CONNECTION TO THE DEVICE
3.1
Serial Connection
A DB-9 cable should be connected between the Serial port on the FS-X25 and the serial port of the target serial
device.
The Serial 1 port can be configured as either P1 (for RS-232 connection) or R1 (for RS-485 connection). Likewise
the Serial 2 port can be configured as P2 or R2. Note that if a P1 and a R1 connection is declared, the one declared
second will cause a configuration error on the error screen.
