MTH DCS Remote Commander in Passive Mode?

Eddie,

From page 206 of The DCS Companion 3rd Edition:

Connecting the DCS Remote Commander Receiver in Passive Mode

The DCS Remote Commander Receiver may be connected to a layout in Passive mode of operation, in the same manner as may a TIU.

Under passive mode, the DCS Remote Commander Receiver obtains its power from the tracks and a power transformer power source may not be connected to the DCS Remote Commander Receiver's Power connector. This allows the operator to control a DCS engine using the DCS Remote Commander Receiver while, at the same time, using the layout's existing transformer controls to operate conventional engines.

For a complete understanding of Passive mode of operation, refer to Part V - Advanced Features and Functions, 10. Passive TIU Mode of Operation earlier in this book. While reviewing that section, consider the DCS Remote  Commander receiver to be the equivalent of a TIU channel.

...and page120:

The only real difference between wiring TIU channels normally and wiring them for Passive TIU mode of operation is that, instead of transformer power for the tracks being connected to the input terminals of the TIU, transformer power is connected to the output TIU channel terminals or directly to the tracks. All other wiring from TIU output terminals to terminal blocks and to tracks remains the same, and the wiring guidelines presented in the DCS Implementation section should still be followed.

To connect a DCS Remote Commander in passive mode to a track system other than RealTrax, just leave the CW-80 connected to the track as it currently is, and use a pair of wires to connect the DCSRC's receiver to the track, red post to center rail and black post to an outside rail.

This and a whole lot more is all in MTH’s “The DCS Companion 3rd Edition", available for purchase  from many fine OGR advertisers and forum sponsors, or as an eBook or a printed book at MTH's web store!

Thank You, I understand.  It is now working!
