Hi,
I want to control a TTL input with the NI 9381. It allows you using a digital output.
I have measured the output signal and it was 2.8 V. The control has failed and I think that 2.8 is not enough to control a TTL input.
The device specifications:
Output high, VOH Sourcing 100 µA..................2.7 V
Could anybody help me?

Hi GerdW, thank you for answer.
I want to turn on and off an equipment. The equipment manual says: The voltage applied to the REMOTE BNC connector must not exceed 5.5 V.
So, I want to send 0 or 1 (0 or 5 V) to turn on and off.
I do not know if I have answered your question. If have not done, ask me again, please.
Best regards

Hi srglzal,
when you want a 5V output signal you should
- at first read the manual, especially page 20, with the specifications of your module
- then build a small amplifier to convert from LVTTL to TTL levels…
RTFM!
