Technical Questions

TQ1: What is the A side, B side configuration of PCI cards and what VIO version should one order?

The Component side of the PCI card is the B side, and the solder side of the card is the A side. If looking from the back of the system chassis, the B side is on the right and the A side is on the left. The PCI bus has 5V, 3.3V, 12V, -12V and VIO on the bus. The VIO is intended as the power to the PCI bus interface controller ICs. The VIO could be either 5V or 3.3V, depending on the motherboard PCI expansion slot design. The PCI expansion slot connector is divided into two sections by a plastic divider called the "key". If the key of the PCI expansion slot connector is located near the back of the chassis then the VIO for that slot is 3.3V. If the key is located closer to the center of the motherboard, then the VIO for that slot is 5V. Most of the 32 bit PCI slots are designed to be VIO=5V. For the 64 bit PCI slot, an additional key is placed between the 32 bit section and the 64 bit extension, dividing the connector into 3 sections. However, the identification of the VIO for the 64 bit slot is the same as the 32 bit slot. For a slower clock (33MHz) PCI 64 bit slot, the VIO could be 5V. For a faster clock (66MHz - 133MHz) PCI 64 bit slot, the VIO is usually 3.3V.

If the user's PCI board gold finger has an additional key cut (two cuts for PCI-32, three cuts for PCI-64), then it is considered as an universal card, which means the board can be used in either a 5V slot or a 3.3V slot. An universal card is not using the VIO power for it's interface controller chip. The I/O board is using either the 3.3V or the 5V directly off the PCI bus. However, since there is no universal PCI connector, when placing an order for the extender, the user will need to specify the connector on the extender to be either a 5V or a 3.3V connector. "Universal" applies to the gold finger area of an add-on board or an extender only. This way the appropriate connector will be used and the keys on the gold finger will be cut in proper places. We would recommend specifying the connector having the same key cut as the slot connector on the motherboard, unless you specifically need to change the VIO.

Warning, due to the cuts on the goldfinger area, one could insert the riser into the motherboard backwards. If that happens, the PCI card, the riser and the motherboard could be damaged severely. Please see the following drawings for the PCI keying configurations.


TQ2: Which of the PCI right angle extenders will fit in a 1U / 2U chassis?

The PCITX4-1, PCITX4-2, PCITX8-1 and PCITX8-2 are designed to fit in the 2U chassis. All the others, except the PCITX4-8 and the PCITX8-7, are the shorter versions that can also be used in the 2U chassis. The PCITX4-5, PCITX4-6, PCITX8-5 and the PCITX8-6 are currently the shortest right angle riser cards and they are designed for the 1U chassis. Please see the following PCITX4 and PCITX8 comparison chart.

TQ3: What is the A side, B side configuration of AGP cards and what Vddq version should one order?

The Component side of the AGP card is the B side, and the solder side of the card is the A side. If looking from the back of the system chassis, the B side is on the right and the A side is on the left. The AGP bus has 5V, 3.3V, 12V and Vddq on the bus. The Vddq is intended as the power to the AGP bus interface controller ICs. The Vddq could be either 3.3V or 1.5V, depending on the motherboard AGP expansion slot design. The AGP expansion slot connector is divided into two sections by a plastic divider called the "key". If the key of the AGP expansion slot connector is located near the back of the chassis then the Vddq for that slot is 3.3V. If the key is located closer to the center of the motherboard, then the Vddq for that slot is 1.5V. Most of the earlier 1X and 2X AGP slot was designed to be Vddq=3.3V. In newer motherboards, the AGP slot is usually 4X, 8X, and the Vddq is 1.5V. Some motherboards may also use a universal AGP connector. The universal AGP connector, as specified in the AGP specification, has no dividing plastic "key". This also means the universal AGP card has no cut on the gold finger, which is the opposite of the two key cuts, specified for the PCI universal I/O card. However, true universal AGP card is very rare, most of the so call "universal" AGP cards actually have two cuts, otherwise, it will not be able to insert into a 3.3V or 1.5V only slots.

The AGP-PRO card is intended for higher performance and a higher power AGP card. Two extra sections are added to the AGP slot. These extra sections consist mainly of additional 12V and 3.3V power and ground contacts. The AGP-PRO connector has an extra shorter key. The shorter key prevents an AGP-PRO card to be inserted into an AGP connector. The AGP-PRO has the same 1.5V, 3.3V and universal configuration as specified in the AGP specification

If the user's AGP card gold finger is cut for a universal configuration, then the board is not using the Vddq power for it's interface controller chip. The card is using either the 3.3V or the 1.5V directly off the AGP bus. When placing an order for the extender, the user should specify either the 3.3V, 1.5V, universal or two cut version. This way the appropriate connector will be used and the key on the gold finger will be cut properly.

Warning, if a two cut or universal AGP riser is ordered, one could insert the riser into the motherboard backwards. If that happens, the AGP card, the riser and the motherboard could be damaged. Please see the following drawings for the AGP and AGP-PRO keying configurations.


TQ4: Which of the AGP right angle extenders will fit in a 1U / 2U chassis?

All the AGPRX4 and AGPTX4 extenders, except the AGPTX4-3, can be used in the 2U chassis. The AGPTX4-5 and the AGPTX4-6 are designed for the 1U chassis. Please see the following AGPRX4 / AGPTX4 comparison chart.

TQ5: What is the life cycle of the PCI / AGP extenders ?

The extenders can be used either to prolong the life of the connector, on the motherboard or to prolong the gold finger of the I/O card. Therefore, either the connector or the gold finger of the extender, will wear out. For most of the straight extenders, built by Adex, the straddle mount connectors are custom made, heavy duty connectors. The life cycle of these connectors are about 1500 to 2000 insertion cycles. If the insertion and removal are aided by mechanical fixtures, the life cycle could be 3000 to 4000 cycles and higher. The gold finger on most of the Adex's extenders are plated with 30 micro inches of hard gold, with minimum 150 micro inches of nickel underlayer. It is designed to withstand 1500 to 2000 insertion cycles or more.


TQ6: What is the Board ID and Vendor ID of a PCI or AGP card ?

The Vendor ID (VID) is used to identify the manufacturer of the controller IC, and the Board ID (BID) is used to identify the type of I/O function for the controller IC (or board). The VID and BID numbers consist of 4 hexadecimal digits (16 bits). These numbers are maintained by the PCI Special Interest Group. The VID and the BID numbers are usually embedded in the first two registers of every PCI and AGP boards. One may also check the following website to see a list of these numbers: http://www.yourvote.com/pci/ .


TQ7: What is the maximum specified power consumption of a PCI expansion card?

5A for 5V, 8 pins (add 5 pins for VIO=5V in 32 bit PCI bus; add 6 more pins for PCI 64 bit bus).

7.6A for 3.3V, 12 pins (add 5 pins for VIO=3.3V in 32 bit PCI bus; add 6 more pins for PCI 64 bit bus).

500 mA for 12V, 1 pin.

100mA for -12V, 1 pin.

375mA for 3.3Vaux, 1 pin.


TQ8: What is the maximum specified power consumption of an AGP card?

6A for 3.3V, 10 pins for AGP (7.6 A for AGP-PRO, 20 pins).

1A for 12V, 1 pin for AGP (9.2A for AGP-PRO, 13 pins).

2A for 5V, 2 pins.

8A for Vddq, 10 pins (can be either 3.3V or 1.5V)

Approximately 100 to 375 mA for 3.3Vaux, 2 pins (may be 1 pin, if the expansion slot is designed for 3.3V or 1.5V instead of the universal)


TQ9: What is the pin out of the PCI connector?

TQ10: What is the pin out of the AGP connector?

Please download the AGPROPO.PDF file to see the AGP and AGP-PRO connector pinout.


TQ11: How to set up the system for remote control of the Bus Isolation Extenders via software command?

The following zipped file is an example of the necessary hardware connection to a system's parallel port. The software is written in simple debugger commands under DOS to turn the powers and signals on the extender to on and off states. User can also use a digital output boards to achieve the same IXCABLE.zip.


TQ12: How to compose the suffix for the part number of the multiple slot risers?

The suffix of the multiple slot risers is composed of three groups of numbers, -XYZ-ABC-W/N. These numbers have slight different meanings to each type of riser cards, as defined in the following.

PAPTX-PCI (PAPTXP) and PAPTX-AGP (PAPTXA):

The PAPTXP and the PAPTXA are combo risers that are capable of up to two 64 bit PCI connectors and 1 AGP connector. The PCI connectors on the riser can be either 32 bit or 64 bit connectors. The AGP connector can be either a 1X/2X (3.3V), 4X/8X (1.5V) or an universal (no key) connector. The PAPTXP is deigned to be inserted into a PCI-32 or a PCI-64 slot on the motherboard. The PAPTXA is designed to be inserted into a AGP slot.
-XYZ identifies the bus size of the three connectors, counting from top to bottom. The X and Z can be 8, 4 or 0, which means 64 bit, 32 bit or no PCI connector. The Y can be 1 or 0, which means 1 or no AGP connector . For example, -818 means a 64 bit PCI connector at the top position , a AGP connector at the middle and a 64 bit PCI connector at the bottom positions. The -414 means 32 bit PCI connectors at the top and bottom positions. A zero in any of the XYZ suffix, means no connector at that position.
-ABC identifies the VIO voltage selection of the connectors. The A and C can be 3, 5 or 0, which means the PCI VIO is 3.3V, 5V or none. This should correspond to the connectors defined in the XZ suffix above. The B can be U, 3, 1 or 0, which means an universal, 3.3V, 1.5V or none for the AGP connector. For example, -313 means 3.3V, 1.5V, 3.3V for each of the connectors specified in -XYZ position. The -515 means 5V, 1.5V, 5V. The 3U3 means 3.3V, Universal, 3.3V. The ABC suffix specifies which keyed connector types to be used. The Universal for the AGP means a connector with no blocking plastic key. The 3.3V keyed AGP connector is used for the 1X or 2X cards. The 1.5V keyed AGP connector is used for the 4X or 8X cards. A zero in any of the positions means no voltage configuration because there is no connector. These multiple risers allow the PCI connector VIO voltage to be different than the PCI slot VIO, where the riser or the cables plug in.
-W/N means the cable lengths associated with the riser. The W reflects the wide cable in inches. The N reflects the narrow cable in inches. The wide cable carries all the signals from a PCI slot on the motherboard to the riser, and the narrow cable carries only the necessary signals from another PCI slot to the riser. For example -1/3 means 1" wide cable and 3" narrow cable. In PAPTX-AGP, the two PCI motherboard slots used by the cables, must have common bus signals coming from a single PCI bridge controller channel on the motherboard. Both slots must run at the same clock speed and have same VIO voltage. In PAPTX-PCI, the AGP signals come from a AGP riser card behind the riser, so only one narrow cable is needed for the 2nd PCI connector. The 2nd PCI motherboard slot used by the narrow cable must have common bus signals as the PCI slot where the riser plugs in.

PCITX3N1 and PCITX3S1:

The PCITX3N1 and the PCITX3S1 are three slot PCI risers with different bus groupings. Both of these risers can be inserted into a PCI-64 or a PCI-32 slot on the motherboard.
-XYZ means the bus size of the three connectors, counting from top to bottom. The X, Y and Z can be 8, 4 or 0, which means PCI-64 bit, PCI-32 bit or no connector. For example, -888 means three 64 bit PCI connectors. The -444 means three 32 bit PCI connectors. The -884 means two 64 bit PCI connectors at the top and one PCI 32 bit connector at the bottom. A zero in any of the XYZ suffix, means no connector at that position.
-ABC means the VIO voltage selection of the connectors. The A, B and C can be 5, 3 or 0, which means 5V, 3.3V or none. For example, -333 means 3.3V, 3.3V, 3.3V for each of the connectors specified in -XYZ position. The -555 means 5V, 5V, 5V. The -335 means 3.3V, 3.3V, 5V. A zero in any of the positions means no voltage configuration because there is no connector. These multiple risers allow the PCI connector VIO voltage to be different than the PCI slot VIO where the riser or the cables are plugged in.
-W/N means the cable lengths associated with the riser. The W reflects the wide cable in inches. The N reflects the narrow cable in inches. The wide cable carries all the signals from a PCI slot on the motherboard to the riser, and the narrow cable carries only the necessary signals from another PCI slot to the riser. For example -2/4 means 2" wide cable and 4" narrow cable. In PCITX3N1, the narrow cable need to be inserted to a PCI slot that has common bus signals as the slot where the riser plugs in. The wide cable can be inserted into another slot that is independent from the other two. In the PCITX3S1, the two cables need to be plug into two motherboard slots that have common bus signals coming from a single PCI bridge controller channel on the motherboard. Both slots must run at the same clock speed and have same VIO voltage.

PEPRX16:

The PEPRX16 is a combo risers that are capable of up to two 64 bit PCI connectors and 1 PCI Express connector. The PCI connectors on the riser can be either 32 bit or 64 bit connectors. The PCI Express (PE) connector can be either a X16, X8, X4 or X1 connector. The PEPRX16 is deigned to be inserted into a PE-X16 slot on the motherboard. However, the gold finger area could be cut down to fit into a X8, X4 or X1 PE slot.
-XYZ identifies the bus size of the three connectors, counting from top to bottom. The X and Z can be 8, 4 or 0, which means 64 bit, 32 bit or no PCI coonector. The Y can be x, 8, 4, 1 or 0, which means X16, X8, X4, X1 or no PE connector . For example, -8x8 means a 64 bit PCI at the top position , PE-X16 at the middle and a 64 bit PCI connector at the bottom positions. The -414 means 32 bit PCI connectors at the top and bottom, with a PE-X1 connector at the middle positions. A zero in any of the XYZ suffix, means no connector at that position.
-ABC identifies the VIO voltage selection for the PCI connectors and PE gold finger size. The A and C can be 3, 5 or 0, which means the PCI VIO is 3.3V, 5V or none. This should correspond to the connectors defined in the XZ suffix above. Since there is no VIO association with the PCI Express cards, the B suffix here is used to specify the size of the PE gold finger area. The B can be 0, 8, 4 or 1, which means no change (X16) to the gold finger, or cut down to PE X8, X4 or X1 size. For example, -303 means 3.3V, X16, 3.3V for each of the connectors specified in -XYZ position. The -515 means 5V, X1, 5V. This multiple riser allows the PCI connector VIO voltage to be different than the PCI slot VIO where the cables plug in.
-W/N means the cable lengths associated with the riser. The W reflects the wide cable in inches. The N reflects the narrow cable in inches. The wide cable carries all the signals from a PCI slot on the motherboard to the riser, and the narrow cable carries only the necessary signals from another PCI slot to the riser. For example -1/2 means 1" wide cable and 2" narrow cable. The two PCI slots that are being used, must have common bus signals coming from a single PCI bridge controller channel on the motherboard. Both slots must run at the same clock speed and have same VIO voltage.

EPPRX16:

The EPPRX16 is a combo risers that are capable of up to two 64 bit PCI connectors and 1 PCI Express connector. The PCI connectors on the riser can be either 32 bit or 64 bit connectors. The PCI Express (PE) connector can be either a X16, X8, X4 or X1 connector. The EPPRX16 is designed to be inserted into a PE-X16 slot on the motherboard. However, the gold finger area could be cut down to fit into a X8, X4 or X1 PE slot. The EPPRX16 is similar to the PEPRX16, but has the top two connector positions swapped.
-XYZ identifies the bus size of the three connectors, counting from top to bottom. The Y and Z can be 8, 4 or 0, which means 64 bit, 32 bit or no PCI coonector. The X can be x ,8, 4, 1 or 0, which means X16, X8, X4, X1 or no PE connector . For example, -x88 means a PE-X16 at the top position , and two 64 bit PCI connectors at the lower positions. The -144 means one PE-X1 at the top and two 32 bit PCI connectors at the middle and bottom positions. A zero in any of the XYZ suffix, means no connector at that position.
-ABC identifies the VIO voltage selection of the PCI connectors and the riser's PE gold finger size. The B and C can be 3, 5 or 0, which means the PCI VIO is 3.3V, 5V or none. This should correspond to the connectors defined in the YZ suffix above. Since there is no VIO association with the PCI Express cards, the A suffix here is used to specify the size of the PE gold finger area. The A can be 0, 8, 4 or 1, which means no change (X16) to the gold finger, or cut down to PE X8, X4 or X1 size. For example, -033 means X16, 3.3V, 3.3V for each of the connectors specified in -XYZ position. The -155 means X1, 5V, 5V. This multiple riser allows the PCI connector VIO voltage to be different than the PCI slot VIO where the cables plug in.
-W/N means the cable lengths associated with the riser. The W reflects the wide cable in inches. The N reflects the narrow cable in inches. The wide cable carries all the signals from a PCI slot on the motherboard to the riser, and the narrow cable carries only the necessary signals from another PCI slot to the riser. For example -1/2 means 1" wide cable and 2" narrow cable. The two PCI slots that are being used, must have common bus signals coming from a single PCI bridge controller channel on the motherboard. Both slots must run at the same clock speed and have same VIO voltage.

EPERXP:

The EPERXP is a combo risers that are capable of up to two PCI Express connectors and 1 PCI connector. The PCI connector on the riser can be either a 32 bit or a 64 bit connector. The PCI Express (PE) connectors can be either X16, X8, X4 or X1 connectors. The EPERXP is designed to be inserted into a PCI-32 or a PCI-64 slot on the motherboard.
-XYZ identifies the bus sizes of the three connectors, counting from top to bottom. The X and Z can be x, 8, 4, 1 or 0, which means X16, X8, X4, X1 or no PCI Express connector. The Y can be 8, 4 or 0, which means 64 bit, 32 bit or no PCI connector. For example, -x81 means a PE-X16 at the top, a 64 bit PCI connector at the middle and a PE-X1 connector at the bottom positions. A zero in any of the XYZ suffix, means no connector at that position.
-ABC identifies the VIO voltage selection for the PCI connector or the size of the PE paddle boards. The B can be 3, 5 or 0, which means the PCI VIO is 3.3V, 5V or none. This should correspond to the connector defined in the Y suffix above. The A and C can be 0, 8, 4 or 1, which means X16, X8, X4 or X1 PE size paddle board at the end of each cable. For example, -031 means 3.3V PCI connector with a X16 and a X1 cable attached. This multiple riser allows the PCI connector VIO voltage to be different than the PCI slot VIO where the riser plugs in..
-W/N means the cable lengths associated with the riser. The W reflects the cable length of the paddle board attached to the top PE connector, in inches. The N reflects the cable length of the paddle board attached to the bottom connector, in inches. For example -2/1 means 2" top cable and 1" bottom cable.


TQ13: How to select a right angle riser to fit properly into an existing chassis cutout?

There are many ways to go about making a selection. One approach would be to follow the below steps:

1. Put your I/O card into the desired chassis cutout, without a riser.

2. Measure the distance from the center of the I/O card's PCB to the top of the motherboard.

3. Subtract that distance by 0.3" for ISA or PCI slot, 0.25" for AGP slot or 0.14" for PCI-Express slot. The result should be the proper connector center height of a right angle riser card.

4. Select a riser card with a connector center height that is the closest match to the calculated height (in step #3). One can use the riser comparison chart for easier selections. The connector center height is measured from the bottom of the riser to the center of the connector.

TQ14: What are the maximum cable lengths on flexible extenders?

The following cable lengths have been tested to function reliably using Adex's flexible extenders. Longer cable lengths are not recommended or guaranteed.

Bus type Bus Speed Max reliable cable length
PCI 32 BIT 33 MHz 5 INCHES
PCI 64 BIT 66 MHz 3 INCHES
PCIX 64 BIT 66 MHz 3 INCHES
PCIX 64 BIT 100 MHz 2 INCHES
PCIX 64 BIT 133 MHz 1 INCH
PCI EXPRESS (all lane sizes), GEN1 2.5 GHz 15 INCHES
PCI EXPRESS (all lane sizes), GEN2 5.0 GHz 12 INCHES
PCI EXPRESS (all lane sizes), GEN3 8.0 GHz 8 INCHES

TQ15: How to determine the proper cable length for single and combo risers?

The slot spacing on the M/B is fixed to 0.8" apart. For convenience and to allow tolerance on the cable, Adex typically uses 1" per slot spacing to determine the needed cable length. For example, if a cable needs to reach from slot 6 to slot 4, then the cable length would be 2". This applies to the single ended flexible risers, as well as the wide cable used on the combo risers. For the narrow cable on the combo risers, an additional 1" increment needs to be added to the cable length, with one exception. The PCITX3N1 riser would require the narrow cable length to be 1.5" longer, due to the PCB design. However, to insure the reliability of the riser, the cable length should not exceed the maximum cable length stated on TQ14 above. We would further recommend the user to specify cable lengths, no longer than necessary.

TQ16: How to measure current using the CSR?

Some of the riser/extender cards offer a CSR option. The CSR (Current Sensing Resistor) can be used to measure the current consumption of the unit that plugs into the riser/extender. The typical CSR has a value of 0.010 ohm, 1% tolerance and rated at 1/2W (5amp). Under operation, the user will simply measure the voltage drop across the CSR, then divide it by 0.010 to obtain the current. I=V/R=V/0.010. A good DMM (Digital Multi-Meter) of 4 digit accuracy is recommended. A DMM with 4 point probes would be excellent. Each CSR can handle only one power rail. Some extenders have multiple CSRs to handle multiple powers.

TQ17: Adex Flexible cable extender configuration

Most of the Adex's flexible cable extenders can be ordered in Female to Male, Female to Female, and Male to Male configurations. The extender cable construction can be either swap or non-swap. The standard extender is Female to Male, with a connector at one end, and a gold finger at the other end, and it is not swapped. However, for Male to Male and Female to Female configurations, the default cable connection is swapped. The swapped version makes proper A/B-side to A/B-side connections with the cable soldered differently. Please see, Adex_flex_cable.

General Questions

GQ1: How does one place an order ?

We suggest you place an order by telephoning us at: (949) 597-1772, faxing us at: (949) 597-1729, or by e-mailing us at: adex@adexelec.com. Our company hours are: 8:30am to 5:30pm, Pacific Standard time, Monday through Friday. Orders placed can not be cancelled after a 30 day period. Order quantity change will incur a price adjustment based on actual quantity ordered or shipped.


GQ2: What are the best shipping methods ?

The most common methods of shipping within the US are as follows: Fedex P1 (overnight, am delivery), Fedex Standard (overnight delivery), Fedex Economy (2 day delivery), Fedex Saver (3 day delivery), UPS Red (overnight, am delivery), UPS Blue (2 day delivery) or Priority Mail (2-3 day delivery, not guaranteed). Other carriers available, but not as commonly used are: DHL, Airborne and Emery. Outside of the US, we suggest you use Fedex, UPS, DHL, Airborne or Emery. To use one of these carriers, we need you to provide your company's shipper account number as we are unable to estimate the cost of tax and duty, where applicable. If it is inconvenient to use your own company's account number to ship against, we recommend you have us ship by way of DHL Collect (they will collect the shipping fees, tax and duty fees upon delivery). Other options for overseas shipping are: Express Mail or Global Priority Mail, through the US postal carrier. Express Mail delivery is generally within one week. Global Priority Mail is the least expensive method, generally takes 1-2 weeks delivery time but only delivers to certain areas and is not guaranteed (no signature is required).


GQ3: How does one open an account with Adex Electronics?

To apply for Net 30 terms with Adex Electronics, Inc, we need your accounting department to fax us your company's trade references and bank information. We will then process your information and set up an account for you provided your trade references are verifiable and you are in good credit standing. For smaller customers just recently established, we prefer to take Visa or Master card for initial orders. If this is inconvenient, we can also ship products out by C.O.D. For our first time overseas customers, we prefer to have your orders prepaid by bank transfer (T/T) or credit card (Visa/Master card).


GQ4: What is the repair and upgrade policy offered?

If you have a board that you wish to have repaired, you may contact us for an RMA (return merchandise authorization) number. Adex offers a repair service as a courtesy to our customers. The flat rate for repairs to bus isolation extenders is $30.00 per board. This does not include the cost for new connectors should they need to be replaced. If your board needs a new connector, the additional cost would be $15.00 each. If your board is damaged beyond repair or you have an older revision that you wish to upgrade, we will take your old board in on trade for a new board at half the list price.


GQ5: How does one buy spare parts?

You may purchase spare parts directly from Adex Electronics, Inc. Please contact us for correct part numbers and pricing on all spare parts.


GQ6: What does it take to get a custom extender card made?

To obtain a quote for a custom designed card, we would need you to provide us with the necessary details of height, dimension, and mechanical information. We would need to know your desired quantity and preferred lead time. The average lead time for a custom designed board is typically 4 weeks. If you wish to have one of our existing boards modified, the cost would then be based on a minimum order of 100 pieces. The lead time would generally be 2-3 weeks. The price would be based on our list price for the first 100 boards. After the first 100 pieces, our volume discount schedule will apply.


GQ7: What is the return and exchange policy on extenders?

You may return a board for credit or exchange it for a different board within a 30 day period, provided the board has not been used. However, only one exchange or return is allowed per order. If you receive a board that is defective due to parts or labor, we will be happy to take the board back and issue you a new one. All defected material must also be returned within 30 days.

GQ8: Do you offer free samples or boards for evaluation?

We do not offer free board samples. However, we do offer our boards for a 30 day evaluation period. We still require a company purchase order or credit card to process a 30 day evaluation order. If you wish to return the board within the 30 day period, we will not charge your purchasing department or refund your credit card (shipping charges are not refundable).


GQ9: How is the weather in Southern California today?

It's beautiful here, haven't you heard…it never rains in Southern California! (smile)
