4 Router communication
You gain access to router for communication purposes by connecting either the router’s
serial port to your computer and/or by using an Ethernet connection.
4.1 Serial connection
Connection can by made trough the serial port(s) of the router; see also Chapter 1 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 detail concerning this protocol, please refer to the following manual: VikinX
Compact Protocol.pdf.
The DB9 female connector for the serial port(s) of the router has the following pin-out:
Pin # RS-232 mode RS-422 mode
1 Not in use Not in use
2 Tx Tx -
3 Rx Rx +
4 Not in use Not in use
5 GND GND
6 GND GND
7 RTS Tx +
8 CTS Rx -
9 Do Not Connect! 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.
4.2 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.
4.3 Ethernet connection
The connections follow the standard set by the IEEE 802.3 100BaseTX specification. The
cables that are to be applied should be CAT-5 / CAT-5E standard, or better. It is the
responsibility of the installer / user to secure a proper installation of the Ethernet connection.
