ESU 53900 DCC Decoder Tester
The Decoder Tester enables you to test any decoder without exposing it to any external factors caused by the locomotive that may influence its performance. In order to make things as easy as possible, the Decoder Tester has all commonly used interface sockets for connecting a decoder: 6-pole NEM 651 socket, 8-pole NEM 652 socket, 21MTC NEM 660 interface, a PluX22 socket and a Next18 interface. Decoders without any interface can be contacted with individual terminals.
A quality coreless motor with flywheel serves in conjunction with LEDs indicating the direction for checking the motor output. An LED monitor informs you about the functioning of the headlights and back-up lights as well as the function outputs AUX1 through AUX6.
For testing LokSound decoders there's an integrated a 20 mm speaker. You can choose whether it should be switched off, or rated at 100 Ohm or 16 Ohm. Two SUSI plugs facilitate the direct test of optional SUSI modules as well as the connection to another circuit board.
The electrical connection to either the command station or the LokProgrammer is facilitated by a removable, 2-pole terminal block (same system as used on the LokProgrammer and the ECoS) or via two solder points. There is an extension board that enables you to also connect our large scale decoders to the Decoder Tester.
