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

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:
