RS-232C terminal
When the OUTPUT 2 CONTROL/REMOTE switch is set
to REMOTE, this unit is able to control by external control-
ler.
The specifications are as follows
RS-232C : 9 pin D-sub (male, with inch type screws)
Electrical Spec. : Based on the RS-232C standard
Recommended cable: Multi-core shielded cable for
data communication
Cable length : Less than 15 meters
Communication format
Baud rate
: 9600 bps
Bit length
: 8 bits
Stop bit
: 1 bit
Parity
: ODD
Use the null modem cable when connecting this unit with
computer.
The parallel input and output terminals are those for remote
control by connecting a simple circuit to the outside of this
unit.
By shorting the input terminal to GND for 100 msec or
more, the crosspoint can be selected.
The output terminal is open collector output, the LED etc.
displays the setting condition of the crosspoint of this unit.
