Serial remote control function
In the serial remote control function, a host such as a computer is connected to the unit. By sending control commands from the host to the unit, the unit can be operated, and the status information of the unit can
be checked both on the unit and host.
RS-232C control
You will be able to perform the three control functions from the
host by connecting an RS-232C straight cable to the RS-232C serial
terminal (9-pin D-sub) connector.
