Issue Details

I am trying to wire my NI SCB-68A and want to print a quick reference label to go on the lid so I can quickly understand the pinouts or signal mappings. Where can I find printable Quick Reference labels or pinout labels for my DAQ device?


The NI SCB-68A quick reference labels for various classes of DAQ devices are linked below. Refer to these links for your specific device series.

Note: The attached files show pinouts for various devices and the terminals they match to on the NI SCB-68A. These pin numbers do not change from device to device; only the labels change, as it is standard hardware mapping of the device connector output to the terminal block. Keep this in mind if a quick reference label does not exist for your specific device. 

Additional Information

Please also note that, for certain devices like the NI 6225/6255, the general NI 63xx and 62xx pinout labels might not accurately describe the true pinout of your device. For example, Figure 2 in the NI 63xx and 62xx documentation suggests that pins 33 and 66 on CONNECTOR 1 of the SCB-68A map to +/- AI 17 for M Series and X Series devices, while the 6225/6255 CONNECTOR 1 documentation suggests that pins 33 and 67 map to the same AI channel (this is correct). When using the various SCB-68A pinout documentation, make sure you use the most appropriate document for your hardware.
