3.13 Digital I/O
Digital I/O functions are supported with the DIO/Analog card
installed.
The instrument uses a DB-9 9-pin interface for digital I/O operations.
A total of 9 pins are available, 8 of which can be configured as
INPUT or OUTPUT and 1 for ground (GND) via remote commands
(Refer to Table 5). The maximum voltage for input is 5 V, and
maximum voltage for output from the supply is also 5 V.
