When configured for unipolar operation, the output voltage can be calculated from the

equation:

A = V * * gain

2.3 Digital Input/Output

The DAQ-16 offers four bits of digital output and four bits of digital input for

control/monitoring of external digital devices. The four digital output lines are LS TTL

compatible and will initialize low (0 volts) on power-up. The four digital inputs are also LS

TTL compatible. There is no termination provided on the digital input lines and a read of an

unused digital input will result in an indeterminate value.
