RCA-1
4. Connecting the RCA-1
Connecting a local detector
You can connect the RCA-1 either
§
directly to the detector which is intended to display the read out
data or
§
to the detector via a data bus line connected to other detectors or
display devices.
When connecting the RCA-1 make sure to connect pin A of the display
device to pin A of the detector and pin B to pin B.
Connecting the power supply
As a power supply you can use an a.c. transformer with 12 – 18 V
already in use on your layout, e.g. for the lighting power supply. On no
account should you connect the RCA-1 to a transformer connected to
the digital system, this would cause a serious malfunction.
It is recommended to use a seperate transformer to supply all RailCom
display devices on the layout.
