This installation of TCS DP2X Digital Decoder is for HO Scale Atlas Trainman RS32 and was performed by Scott Russell of Sandy Hook, CT
Important Soldering Tip:
Please do not use any flux either liquid or paste on the mother board. It will damage it. Use only Rosin core solder approved for electronics use.
We recommend to use only Kester "44" rosin core, SN63PB37, .015" diameter, part number 24-6337-0007.
This can be ordered from Techni-Tool under Techni-Tool part number 488SO157 http://www.techni-tool.com
It is similar to
the RS-11 (it uses the same chassis). Atlas twists the truck wires above the end
of the board and next to the plug. The wires need to be moved out of the way
temporarily so the decoder fits flat. Then the wires can be twisted back out of
Note the DP5X is shown here , but that decoder has since been replaced by the DP2X.
Other solder tips:
When stripping wire, only strip a tiny little bit of the insulation. Strip no more then a 1/64 of an inch. When the wire gets tinned with solder the insulation will shrink back more. Try to not expose any more wire then 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.
