This installation documentation is for the HO-Scale Broadway Limited Blue Line SD40-2. This installation uses the M1P-1" decoder, and was performed by a TCS customer.

There are several good options for installing a TCS decoder in this Blue Line SD40-2 locomotive. The DP2X is the most simple and straight forward, it plugs directly into the 8 pin NMRA socket supplied with the locomotive. The TCS extension plug must be used with the DP2X decoder for this installation. The extension plug is sold separately from the decoder. The T1P-SH, the MC2P-SH, or M1P-SH will also work just fine. Plug in the decoder so that the Orange wire lines up with Pin #1 of the socket. Pin #1 will be designated with a "1" or a small arrow/chevron.

Important Soldering Tip

Please do not use any flux either liquid or paste on the mother board. Over time, the acidic properties of liquid or paste flux will begin eating away at the fiberglass PCB and will damage it. Use only Rosin-core solder or no-clean flux approved for electronics use.

TCS recommends the use of Kester "44" Sn63 Pb37, .015" diameter Rosin-core solder. Kester part number 24-6337-0007.

You can order this solder from the following retailers:
Digikey - PN:KE1110-ND
Techni-Tool - PN:488SO6775

Other solder tips

When stripping wire, only strip a tiny little bit of the insulation. Strip no more than a 1/32 of an inch. When the wire gets tinned with solder, the insulation will shrink back more. Try to not expose any more wire than half the length of the solder pad at most. In no case should solder or exposed wire wire ever be outside the boundary of the the solder pad you are attaching a wire to.
