1552 TCS Train Control Systems / IMFP4-NF 4-Function DCC Decoder f/Intrmntn FP7/FP9 (SCALE=N) Part # 745-1552

The IMFP4 - NF 4 - Function DCC Decoder is a must - have for N scale train enthusiasts. It's specifically designed to fit Intermountain FP7 and FP9 locomotives with a soldered - wire motor mount. With a drop - in interface type, it's easy to install. Its dimensions are 2.207' x 0.551' x 0.179' (56.05mm x 14mm x 4.54mm). It offers a continuous/peak current of 1.0/2.0 Amp, 4 total functions with a function rating of 80 mA, 4 12V outputs, and 4 LED outputs. This decoder is perfect for InterMountain FPA - unit locomotives like FP7A and FP9A. It's designed for the newer InterMountain frame where the motor connects to the control board via wires. Key features include Back EMF Load Compensation for great slow - speed control, Quiet Drive for noise - free motor performance, DC Mode for automatic DC power detection, RailCom® for communication with the command station, Variable Momentum for custom acceleration and deceleration, LED Support without the need for external resistors, Incandescent Bulb Support for 12 - Volt bulbs, Function Remapping for easy lighting control, 20 Programmable Lighting Effects, Dimmable Brightness for customizing light levels, Decoder Lock to prevent accidental programming, Airwire™ Compatibility, and User - Loadable Speed Tables for custom speed curves and limits.

Using this IMFP4 - NF 4 - Function DCC Decoder is a breeze. First, make sure your locomotive is an Intermountain FP7 or FP9 with a soldered - wire motor mount in N scale. Then, simply drop the decoder into place as it has a drop - in interface. When you power it up, the decoder will automatically detect DC power. You can configure how your lighting effects work on DC. For customizing speed and lighting, you have a lot of options. You can set custom acceleration and deceleration curves using the variable momentum feature, and choose from 20 different programmable lighting effects. You can also set different brightness levels for your lights. Just be careful when programming the decoder. Activate the decoder lock feature to prevent any accidental changes. When it comes to maintenance, keep the decoder clean and free from dust. If you have any issues, refer to the installation pages for a list of compatible engines and check the connections to the motor and control board. Also, since it supports RailCom®, you can look into future expansions for new features.
