TCS-1596, Auxiliary Decoder Tester and Expansion Board
This auxiliary decoder tester board adds additional connectors to your TCS Decoder Tester. Simply inset the head pins into the screw terminals on the decoder tester and you are ready to use the additional connectors.
TCS' premium decoder tester provides an easy way to test and program your decoder prior to installation, or perform diagnostics.
The TCS decoder tester and expansion board are mounted on soft rubber feet. The TCS decoder tester sets up in seconds with the simple attachment of track power via screw terminals. Our tester is 100% compatible with any command station.

- 7-Pin JST (MC-series)
- 6-Pin JST (FL2)
- 7-pin WOW Aux Harness
- 2-pin Keep Alive® (Input)

*Speaker output is only to be used if no other speaker is connected, including the decoder tester's onboard speaker. Speaker input is only to be used if a decoder is NOT connected via the WOW Aux connection.
