7.3 Installation
7.3.1 Setting the Operation Mode
Setting the operation mode
Turn off the power switch before setting the operation mode. Use the operation
mode setting switches A1 to A4 (SET A). A1 and A2 control the mode for port 1, and
A3 and A4 control the mode for port 2. (Ports 1 and 2 can be set independently.)
Setting port 2
Set port 2 to either RS-232C or RS-422A modes.
• If port 2 is set to RS-232C mode and is connected to an external unit set to
RS-422A mode, the connected unit may be damaged.
• When setting port 2 to RS-232C mode, set the TERMINATOR (terminal
resistor) to OFF.
