Atlas GP7

"Plug and Play" install with TCS TH150DP

On the top of the TCS TH150DP decoder is a part with a marking of "8.00". This part is used to orient the decoder in relation to the locomotive's cab during installation. The TCS provided extension socket is used for this installation.

TH150DP Decoder
8.00 part away from cab
Use supplied extension plug

Important note: recent versions of the GP7 from Atlas has the locomotive circuit board attached to the top of the motor turned 180 degrees from the picture.
That arrangement does not allow clearance for the TH150DP.
This can be fixed by turning the locomotive circuit board end for end (see instructions below)

Train Control Systems TH150DP

  • 14/28/128 speed steps, extended addressing, advanced consisting
  • 1.3 amps, quiet drive, dither, function remapping
  • Five functions (each rated 125ma), Special lighting effects
  • OPS, Direct, Paged, Register and Bit Manipulation programming
  • NMRA medium 8 pin plug, 0.845"x0.68"x0.165"
  • Photo provided by Train Control Systems. Used with permission.
If you need to turn the GP7 locomotive circuit board end for end:
  1. Remove the four push clips that attach the wires from the trucks.
  2. Remove the circuit board, turn it end for end, and reinstall.
  3. Reattach the four wires with the push clips.
  4. Install TH150DP decoder as shown above with 8.00 part oriented away from the cab.
  5. Remove motor leads from the locomotive circuit board and swap them (black is now where red was, and vice-versa).
  6. To get the correct auto reverse operation of the headlights make CV49=16 and CV50=00.
