Transponding

Transponding & Rocrail

Transponding can be ordered to the same category as Lissy and RailCom but uses another technique.

With the basic transponding decoders the following info is received by Rocrail:

  • decoder address
  • BDL168 board number
  • zone A, B, C, D, E, F, G or H


More advanced transponding decoders can supply also:

  • operations mode readback of decoder CVs
  • information about the speed and other status data
  • surround sound system support



Addressing

To avoid conflicts with the current sense addressing bus 2 is used for the transponder receivers.
So if the board address is set to 1 the first transponder receiver will report in Rocrail with address 2-1, and the first sensor with address 0-1. (bus-address)

The BDL168 transponder addresses increment by 2, not 1. This means with board address 2 that Zone A is 1, Zone B is 3, etc. See this table:


Board 1 RX's
Zone Bus Address
A 1 1
B 1 3
C 1 5
D 1 7
E 1 9
F 1 11
G 1 13
H 1 15
