PSR BUS
Used together with a dedicated modular cable to connect to a PSR series power supply
unit.
RS-232C
Used together with a crossover cable to connect to the RS-232C of a PC.
LOCAL/PSR-M
BUS
Used together with a dedicated modular cable to connect to the local bus.
Specifying the appropriate settings enables it to be used as a unit compatible with
PSR-M series power supply units.
CN1
Connects to the power unit. For details about how to connect to the power unit, see the
IF-71RS instruction manual.
CN5
Connects to the terminator of the local bus and the internal bus when he circuit is
closed. In the local bus, a terminator is required for the power supply units at each end of
the signal line or for stand alone.
