8. Remote PLC
8.1 Signal Output
The rear panel connector of the 300XAC Series provides output signals to
remotely monitor PASS, FAIL, and PROCESSING conditions via a 9-Pin D-type
connector. When a terminal becomes active the relay closes thereby allowing
the external voltage to operate an external device. The following table provides
the conditions of each pin and the relay state.

8.2 Signal Input - 7 Memory Recall (Opt. 04)
The 300XAC Series also provides an optional remote input interface (Opt. 04) to
control any test operation via remote. The 9-Pin D-Type connector signals for
Test, Reset, and 7 Memories (M1 – M7) input control signals. PLC remote
functions will be activated once the PLC Remote from the System setup
Parameter is turned on. Upon turning on the PLC Remote setting, the
TEST/RESET LED will be lit and the buzzer will beep twice before returning to
the RESET condition, when any key on the front panel is pressed. Whenever
