Table 2-3. Jumper J4 Configuration; Digital Input/Output - Omega Engineering DAQ-16 User Manual

When configured for unipolar operation, the output voltage can be calculated from the
equation:
For bipolar operation, the equation becomes:

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.
