Any mobile (loco) decoder that is capable of operating a motor. I would look for the cheapest available! Lais seem to be around the cheapest. Example... ebay Lais decoder

Cut off the 8 pin plug** and connect the decoders Red and Black wires to the DCC bus pair and the Orange and Grey wires to the TT motor terminals. All other wiring from the decoder is not needed, but the Blue with Green could be used for one or two lights around the TT. Green is the Negative while Blue is the Positive to all function outputs.
** You could leave the 8 pin plug and wire an 8pin socket to the DCC bus and TT motor, then the decoder is plugged into the socket making it easy to replace it if ever needed!

Set decoders address number to whatever you want the TT to operate on. On the Select this has to be in the range of 1 to 59. Then the DCC console will operate the TT in the direction set and at the speed set.

Thank you, Brian.
As always, an easy-to-follow reply which even I can follow. I have a spare decoder which I thought I could only use on Locos so I will give it a go.

Good afternoon, Brian.

Done all the above, Red & Black to bus wire, Grey & Orange to motor, set Select Controller to 40, no rotation of motor shaft. Checked Voltage output at the output of decoder, got 15v. Wired up the Peco motor to independent 12v supply, plug in Peco controller, all worked! Put unit back to "bus wire" connection and left the Peco controller connected, still no work, but the green light on the Peco controller was alight, indicating power.

Can you help solve the problem?

Thank you

John

PS. Looked at your website for Turntables and your instructions match what I have done.

I presume the decoder has also been given address 40?
I would start with a factory reset to put it back to address 0003 then test it on that address first.

Hi
What you have, discovered from another thread here, is the Peco PL-55 stepper motor and control unit. It just needs a 2.0Amp 12volt power supply and cannot be used with DCC.

For DCC operation via a loco decoder a standard 12volt DC motor and reduction gear is needed.
