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, or NCB ports,
at the same time. Doing so may cause loss of important communication and
control data.
5.1 Serial connection
Connection can be made through the serial port of the router; see also Chapter 2.5 for
connection details.
The communication parameters are configurable. Please refer to the protocol
documentation of the appropriate communication/control protocol.
Example: The protocol parameters of the VikinX Compact routers are as follows:

Bit rate 19200 bit/s

Data bits 8 bits

Stop bits 1

Parity: No parity
For further details concerning this protocol, please refer to the following manual:
NCB Protocol.pdf .
The DE9 female socket for the serial port 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.
It is the responsibility of the installer / user to secure a proper installation of the
RS-232 connection.
