In Figure A , there are effectively two cable runs of 50M each, with two stations on each run. This
is acceptable because it is permissible to have two stations on a 50M run of cable.
(see section " MAXIMUM LENGTH OF CABLE RUNS")
In
Figure B , there is only one cable run of 100M in length, with four stations on the run.
This is unacceptable because it is only permissible to have one station on a 100M cable run
(see section " MAXIMUM LENGTH OF CABLE RUNS")
Because a DC power supply is used, it is important that the positive lead of the power supply
connects to the POS terminal and the negative lead of the power supply connects to the NEG
terminal of the applicable Room Station.
