Then each lane has to be divided into equal parts, called lines: lane 1 (with 4 lines: line 1, line 2, line
3 and line 4) and Lane 2 (with 2 lines: line 5 and line 6).
The cable lengths or number of loads (sensors) must not be exceeded when the modules are
connected to the CMCG (i.e., maximum 50 sensors and 150 m (490 ft) of wire in a line).
In the example below, the distance between the sensors is 3 m (9.8ft).
The small dots represent the wiring nodes and the black lines indicate the distance between the
CMCG to the 1
st
sensor of each line.
As shown in the table below, for all the lines the maximum limits are not exceeded:
