A novelty: with this adapter you have a whole 12 amplified individual outputs for switching loads!
All outputs come from the 21MTC interface and can be used directly.

It also has a direct connection for a buffer electrolytic capacitor (when using ESU decoders).

The following connections of the 21MTC interface are amplified:
Pin 1, 2, 3, 4, 5, 6, 13 and 17.

With the ESU LokPilot v5 decoder the following outputs are thus available:

  8 Light forward
  7 Light backwards
15 aux 1
14 Aux 2
13 aux 3
  4 Aux 4
17 Aux 5
  3 Aux 6
  2 Aux 7
  1 aux 10
  6 aux 11
  5 Aux 12

With ZIMO MS series 11 amplified outputs are available, with ZIMO MX series and Doehler & Haass DH21-B4 their 10.
On ZIMO decoders, set the outputs Aux 3 and Aux 4 to "Logic outputs" when using this adapter.
(With CV # 8 = 3 > MX634D (MX638D) is converted to MX634C (MX638C) (i.e. outputs FA3, FA4 become logic level outputs).

This decoder adapter can be screwed on with the break-off tab or fastened with mounting tape.
