Doorking 2358-010 Tracker Expansion Board (replaces 2351-010)
Easy to install, and the included instructions were essential to programming. It's a more sophisticated version of the 2351-010 it replaces, so you can't just swap wires but the instructions made it straightforward. Great packaging and shipping - at the best price around! Gatehouse Supplies continues to provide us terrific service!
