Configuration
Function of the LAN interface X1P1
● The X1P1 interface (Ethernet RJ-45) of the CMR is used to connect a local PC for the
configuration.
● After completed configuration, the X1P1 interface serves to connect to the BM only if the
CMR is not being operated in standalone mode (Page 38).
You will find the properties of the X1P1 interface in the technical specifications (Page 143).
By using autonegotiation and autocrossing, the transmission speed, duplex and polarity are
detected automatically.
Configuration of the Ethernet interface
Note
IP address and subnet mask according to RFC 1918
The factory
-set IP addresses and subnet masks can be changed as required, but must keep
C 1918. The CMR does not run any strict checks of the address
Do not set an IP address that is already assigned in your LAN, for example for other BMs.
If a duplicate IP address is detected, the red error LED starts to flash. The CMR is no longer
av
ailable via the Ethernet interface. No other functions are affected: e.g. sending an SMS
message due to events of the CMR itself.
