Communications
The Communications screen allows the user to configure the N-664’s four serial ports.
Each serial port has a fixed number indicating which hardware port it corresponds to.
These numbers cannot be changed. Each serial port also has a user-settable text label
identifying it for user documentation purposes. This string can be up to 15 characters
long.
The serial mode drop-down menu allows the user to select both the hardware interface
and the software behavior of each serial port. The hardware mode of each port can be
selected between RS232, RS485 in 4 wire mode, and RS485 in 2 wire mode, to control
the hardware behavior of the serial output pins. RS232 mode ports can be connected to
customer equipment with any standard serial cable. RS485 2 wire or 4 wire ports will
need to use a custom header to connect to customer equipment.
The software mode can be selected from server or client mode. “Disabled” mode can be
selected to leave a port completely unused.
