DP5X Decoder
The DP5X decoder (formerly called the TH150DP) is designed as a direct Plug N' Play to fit many different HO and OO scale locomotives (see list of known incompatible locos). There is no wire harness and no soldering is required. Installation is very easy. Plug the decoder directly into the locomotive DCC socket. DP5X is a five function, full featured decoder not a stripped down decoder. It is ideal for locos such as the Heljan Hymek and Class 47 diesels.

Features:
-
Auto detect allows operation on DCC only or DCC and DC power. TCS decoders are almost transparent on DC making the engine act like a decoder isn't there. Brake on DC allows you to control the lights while the train is in a DC block.
-
Quiet Drive is active at all times which greatly reduces engine noise.
-
Dither provides rapid bursts of power to overcome resistance. You control both the power and frequency. See slow speeds unequalled in the industry.
-
Lighting Effects: Auto reversing headlights, Mars, Gyra, Rotary Beacon, Single and Double Pulse Strobe, Opposite Dim, Flashing and Random flicker. Rule 17 headlight dimming can be set to occur when stopped, opposite the direction of travel, or both. You always have manual control.
Button Control allows you to pick the control buttons of your choice. -
Factory Reset lets you change most of your choices back to their factory default values if you get into a situation you don't like.
-
128 speed steps are active when Mid volts, Top volts, Start volts or the user loadable speed table is active for much smother operation.
-
Primary 2 digit addressing or advanced 4 digit addressing may be used.
-
Consist Addressing has a Special Feature allowing you to automatically turn off any undesired lighting when you add the engine to a consist.
-
Goof Proof Warranty as always. One year no questions asked replacement warranty. Handled entirely by TCS.
-

Class 52 Diesel |
There is insufficient space between the NMRA socket and the interior of the roof to plug in a DP5X. | Use M1-UK, MC2-UK or T1P decoder, which have NMRA plugs fitted |
Hornby |
Class 50 Diesel |
The underside of the PCB comes into contact with components on the main board in the loco and will cause a short circuit. If the extension plug is used, as supplied with the decoder, this raises the DP5X too high and it is not possible to refit the body. | Use M1-UK, MC2-UK or T1P decoder, which have NMRA plugs fitted |
