TCS T1-LED, HO Scale Motor Decoder:
The T1 LED has added Blue and Black/White wires for the use of a KeepAlive device. This decoder has internal resistors for LEDs eliminating the use of external resistors for F0F or F0R. This decoder may be hard-wired or plugged directly into any locomotive with a 9-pin JST plug. Use the standard T1 decoder if your locomotive uses incandescent bulbs.
Note: The Green and Purple wires on this decoder are not used. The T1-LED is a 2-function decoder, but still uses the 9-pin JST which includes the Green and Purple wires.
 
Back EMF Load Compensation: Provides superior slow speed control and high performance under load.
Quiet Drive: Super-quiet motor control for "buzz" free motor performance.
DC Mode: Decoder will automatically detect DC power. You can also configure how your lighting effects function on DC.
RailCom®: This feature allows the decoder to talk to the command station. RailCom supports expansion for new features.
Variable Momentum: Allows you to make custom acceleration and deceleration curves.
LED Support: This product does not require external resistors when connecting LED's.
Function Remapping: Buttons 0 through 12 may be used to control the lighting functions of this decoder.
Programmable Lighting Effects: Choose from 20 separate user-programmable lighting effects!
Dimmable Brightness: Configure multiple different brightness levels for your LED's or incandescent bulbs.
Decoder Lock: Feature which prevents accidental/unwanted programming while activated.
Airwire™ Compatible: Fully compatible with Airwire™ operation.
User-Loadable Speed Tables: Configure custom speed curves and set speed limits.
