Serial remote control
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. There are 2 methods for connecting the host and unit, namely RS-232C control and IP Control.
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.
