Generating a Digital Sample (Line)

You can use the digital lines in your DAQ device to generate a digital sample. This operation is based on software timing. Each line corresponds to a virtual channel in your task.

All E and M Series devices support TTL (transistor-transistor logic)-compatible digital signals. A TTL signal has two states, logic low and logic high:

Logic Low = 0 V to +0.8 V

Logic High = +2 V to +5 V

Common digital generation applications include controlling relays and driving external devices, such as an LED.
