5 Router communication
You gain access to router for communication purposes by connecting either the router’s
serial port to your computer or by using an Ethernet connection.
Do not use both the router’s Ethernet port and RS-232 serial port at the same
time. Doing so may cause loss of important communication and control data.
5.1 Serial connection
Connection can by be made through the serial port(s) of the router;
The communication parameters are configurable. Please refer to the protocol documentation
of the appropriate communication/control protocol.
Example: The protocol parameters s are as follows:
− Bit rate 19200 bit/s
− Data bits 8 bits
− Stop bits 1
− Parity: No parity
The DB9 female connector for the serial port(s) of the router has the following pin-out:
Pin #
RS-232 mode
1 Not in use
2 Tx
3 Rx
4 Not in use
5 GND
6 GND
7 RTS
8 CTS
9 Do Not Connect!
Note that if the standard RS-232 cable specification (DCE) is followed:
A cable with Male+Male or Female+Female connectors at the cable ends is used
for Rx/Tx crossed connection, and
A cable with Male+Female connectors at the cable ends is used for a straight
through connection.
5.1.1 Maximum cable length (RS-232)
IEEE has specified the maximum cable length for an RS-232 connection to 15m. Longer
distances can be installed depending on the environmental conditions of the installation site.
