Com - RACOM RipEX User Manual

7.3.4. COM

* Active only when Router mode
The COM ports in RipEX are served by special daemons, which are connected to the IP network through
a standard Linux socket. Consequently a COM port can be accessed using any of the two IP addresses
(either ETH or Radio interface) used in a RipEX and the respective UDP port number. The source IP
address of outgoing packets from COM ports is equal to IP address of the interface (either Radio or
Ethernet) through which the packet has been sent. Outgoing interface is determined in Routing table
according to the destination IP. The default UDP port numbers are COM1 = 8881, COM2 = 8882. If
necessary they may be changed using CLI, nevertheless it is recommended to stick to the default values
because of dependencies between different settings (e.g. Protocols) in the network.
Important
UDP port settings is valid only in Router mode. In Bridge mode all packets received by COM
port are broadcasted to all COM ports on all RipEXes within the network.
■ Type
