5V power supply at SCB 68 from PCI 6602?

[happyeveryday]

Hi,

Is this proble resolved? I had the same problem. I can not get 5V at SCB 68 from 6602.

Besides, The last two DIO (P0.30 and P0.31) are not working.

Hello Yi,

If you are experiencing issues with both the 5V output and the DIO lines on your 6602 device, the device itself may be in need of repair. There is a page called "Sending in a National Instruments device for Repair or Calibration" that details how to go through this process. 

If you are interested in going through additional troubleshooting in this forum, I will be happy to work with you.

Hello,

I also have a problem with a missing +5V which should be at PIN 1 at the SCB-68 in combination with a PCI-6602. The switches are in the position as described in the SCB-68 Label for TIO devices. As I understood in the SCB-68 manual this means the accessory power is disabled, but from PIN 4. Am I right? So why do I not have +5V on PIN 1 as described on the label?

All other PFI outputs (including 30 and 31) are working properly.

Regards,

Karl

Hello Karl,

You should have access to the +5V on PIN 1 with your PCI-6602 when used with the SCB-68. I would appreciate if you could clarify some aspects of the issue:

Does the card function properly otherwise?

Exactly what settings do you have the switches set to currently?

Are you referencing the +5V to the DGND?

If you use direct feedthrough mode as shown in Table 2 of the SCB-68 User Guide, are you still unable to read +5V?

Hello Andrew,

thanks for your reply. I couldn't measure it  yesterday, but it worked this morning (don't know what I have done wrong yesterday).

I had a similar problem.  It turns out that 4 of the pins on the SCB-68 connector were pushed in, so that when you plugged in the cable, they did not make contact.  I used a screwdriver to push on the pins from the inside, to make them look like the other pins from the outside.  Now my 5V is restored.

It looks like in my SCB-88A pin 1 and 35 is +5v. and pin14, 8 and 9 is Ground.
