6.1 Controlling 3154 with External I/O

External I/O terminal connector board is located in the back
and enables signal input for START STOP test voltage
control and signal output for 3154 status (TEST status,
etc.) comparator judgment results.
All signal leads are isolated through a photocoupler from
other parts. (Not isolated between signal leads)
Use external power supply (5 to 30 VDC).
Internal power supply 5 V and GND are output by external
I/O terminal enabling simple external I/O functions. Use
caution because external I/O, RS-232C connector and
analog output terminal are not isolated.
