USB-4431 Digital I/O

[jiggle]

Hello, there.

I can not find the digital I/O in MAX Test Panels for device USB-4431.

Please tell me what should I do to test the Digital I/O port of my USB-4431?

Thanks!

According to the specifications for that module there is no digital I/O.

Dear GovBob,

Thanks for the reply.

I wonder what is the function of the "Digital I/O & PFI" port? 

[GovBob · Accepted solution]

The specifications state:

Digital I/O Lines

Power-up mode ......................................................Inputs pulled low

Input protection......................................................+5.6 V/–0.5 V

Purpose...................................................................Start or reference trigger (importing only)

Source ....................................................................PFI<0..7>

Compatibility .........................................................Transistor-transistor logic (5V TTL)

Polarity...................................................................Rising or falling edge

So it looks like they are for triggering.
