cable diagram/connection diagram for shc50-68

[_S_G]

I am using a 50 pin to 68 pin cable to connect the digital pattern on my Arbitrary Waveform Generator (NI 5411) to a breakout box, and I am unable to find documentation on how the pins on one end of the cable are connected to the pins on the other end.

Where can I find this document?

Hi S G,

I will look into this, and post back ASAP when I have more information.

S G,

This knowledgebase has the pinouts that you are looking for.

Thank you.

I had a problem with 2 signals after plugging this cable into a SCB-68 breakout box and a PXI-5411.  I created a simple VI that exercised all 16 digital outputs of the digital connector.  This alone wasn't too easy considering I could not find an example for sending a digital pattern out the digital connector (there are a bunch for sending an analog signal out).  Anyway, pins 7 and 8 in the box appeared to be conflicting with each other since there was a 3rd voltage level appearing midway between a high and low.  After troubleshooting I flipped S1 and S2 in the box to the right, and the signals looked good.  The SCB-68 User Manual shows the correct switch settings in table 2-1 for "Direct feedthrough."  What is misleading is in the manual "Installation Guide - IMAQ SCB-68 Connector Block and IMAQ SH68-C68 Cable" (373053a.pdf) it shows in Figure 1 on page 3 the opposite directions for setting the switches, even though the text immediately above it says it's doing the same thing.  Maybe someone was looking at the box upside down when they drew the images... or pasted them upside down in the document?

Anyway, I attached my 1st working attempt at getting a digital pattern out the digital connector (in LV 8.5).

Hi Brad,

The IMAQ SCB-68 is actually a different product than the SCB-68.  IMAQ referes to our Image Acquisition product line, and that specific breakout box is designed to be used with these devices.  It will have different switch settings than the SCB-68, which is a more general-use breakout box.

Now that you have the switches set correctly, are there any other problems with the digital outputs?  It sounds like you have everything up and running, but please let us know if you encounter any issues.  I apologize for any inconvenience--I can see how the naming of the two breakout devices would be confusing.  Thanks for posting and Happy Holidays!
