5-12 APPLICATION OF CENTRALIZED CONNECTOR
The DPM-900/950 series provides a centralized connector on its rear panel. Generally, the connector is
used to connect with an AC power supply via the accessory power cable. The connector also provides a pin
that connects with a DC power supply. The connector also enables connection of input/output signals.
Names and functions of these signals are shown in the following table.
For details of external control signals (with REM on the signal name) in the table, read “5-13 REMOTE
CONTROL.”

5-13 REMOTE CONTROL
The following functions can be controlled remotely.
Execution of balancing
REM BAL signal
Outputting CAL
REM +CAL, REM –CAL signals
Execution and cancellation of key-lock
REM KEYLOCK signal
Remote control has the same significance as manual operation of the front panel switches that control the
DPM-900/950 series functions. The priority is given to the first operated one.
