With this adapter, you have 6 amplified, independent outputs for switching loads!
All outputs come from the 21MTC interface and can be used directly.

In addition, this adapter has a direct connection for a buffer electrolytic capacitor (when using ESU decoders).

The following connections of the 21MTC interface are amplified:
Pin 4 and 13 for Aux 3 and Aux 4.

The following outputs are thus available:

  8 light forward
  7 Light backwards
15 aux 1
14 aux 2
13 aux 3
  4 Aux 4

On ZIMO decoders, set the Aux 3 and Aux 4 outputs 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 breakaway tab or fastened with mounting tape.
