RailCom Data Display
RailComDisplay is a local detector that displays data transmitted from RailCom decoders.
When a locomotive enters in a isolated section connected to RailComDisplay, the data transmitted by the decoder will be displayed: its address and depending on decoder its speed, temperature and load.
It does not matter whether the locomotive in this section stop or whether is in motion, data are send continuously
This circuit can also display the CV value when they are read using PoM while the locomotive is in the isolated section
RailComDispay requires that a ‘cutout’ device conforms the DCC signal, to be able to visualize the transmissions and the decoder has active the RailCom functions. The isolated section should be at least twice the length of your longest locomotive.
Installing RailComDisplay is easy; signal from booster is connected to J and K terminals, and the isolated track section to the terminals J1 and K1. Data are displayed in a 16 characters, two lines LCD display. If you use backlight, connect to an external power supply, not to the internal 5V.
In order to program the PIC you can download the HEX file.
NOTE: In 2008 following NMRA RP-9.3.2, besides of address and CV, Lenz Gold sends speed and temperature and Zimo decoder sends speed, temperature and load, but now RailCom specification is changing to RailComPlus not following the RP-9.3.2 of the year 2008 so with new decoders as Lenz and ESU you only get address and CV that are compatible with RP-9.3.2
