4.2 X1P1 (LAN) interface

4.2 X1P1 (LAN) interface
Connecting the X1P1 (LAN) interface
The interface supports autonegotiation and autocrossing. For the connection, use a patch
cable with an RJ-45 plug. You will find the properties of the X1P1 interface in the technical
specifications.
● Connect your local area network, the PC or the BM to X1P1 (LAN) of the CMR.
Inputs and outputs
The CMR has two inputs and two outputs. The connecting terminals are on the underside of
the device.

Inputs I1 and I2
The connecting terminals of the inputs are labeled I1 and I2. The reference potential for both
inputs is "M".
Using the Web user interface, you can assign any function to each input, for example
triggering an alarm SMS message (Page 94).
The status of an input can also be read using SMS.
Outputs Q1 and Q2
The connecting terminals of the outputs are labeled Q1 and Q2. The reference potential for
both outputs is "M".
You can assign any function (Page 94) to each output using the Web user interface. The
outputs can be set and reset using SMS messages.
Note
Remember the electrical load capacity of the output.
You will find the electrical values for the inputs and outputs in the section Technical
specifications (Page 143).
