Digital I/O Port - Keysight Technologies E5260 Series Programming Manual

Table 2-2

Digital I/O Port

The digital I/O port is used for the trigger input/output terminals or an interface to
control an external relay circuit and so on. For the trigger input/output, refer to
"Trigger Function". For another usage, the following commands are available:
ERM Changes the digital I/O port assignments.
ERS? Returns the digital I/O port status.
ERC Changes the output status of the digital I/O port
Connector type of the digital I/O port is D-Sub 25-pin. The pin assignment is shown
in Table 2-2. In the initial setting, the all port forces TTL high level (approx. 2.4 V.
TTL low is approx. 0.8 V). The above commands are available for non trigger ports
from DIO 1 to DIO 16.
