There is absolutely no programming nor soldering required.  The 3 wires from the detectors are attached to the control unit using screws built into the control unit.  It couldn't be easier.

The fibers are inserted into two "chimneys".  Each can hold either a 1.0mm fiber or a 0.75mm fiber.  The HO Tall Block Signal uses a 1mm fiber.

When ordering the kit, select

1. Whether you want a power supply (9V) (extra cost) or not (in which case you can use your DC bus from your layout which must be >7V with center positive wiring into the power jack connector provided in the kit) and you are done.

If you have a double track, just order another 2 detectors that you will find on our site and they will be added to the kit.
