The Device oers serial ports named as COM1 and COM2. For remote control of the serial ports

the protocol known as RFC 2217 is used.

Figure 59: NetCom Conguration

The upper section COM1 congures operation of serial port COM1, while section COM2 congures

the COM2 port. By default the positions of the DIP switches decisive of the active mode. The

DIP switches are on the underside or back of the device. If the position of the DIP switches is

select by software (OFF OFF ON ON) the conguration of the SW-Mode is valid. The SW-Mode

supports the modes: RS-232, RS-422, RS-422 with termination, RS-485 full duplex, RS-485 full

duplex with termination, RS-485 half duplex, RS-485 half duplex with termination, DIP switches

congured mode and loopback mode.
The connection for remote control is via TCP/IP, so a TCP Port is required. By default the rst

serial port uses 5100, the next ports use 5101 and following (if there are more than two ports). The

serial ports then operate in the same way as the
