The Digi-Code DC5100 is a single-channel, Multi-Code compatible radio receiver designed to add or restore remote control to garage door openers, gate operators, and access control systems. Operating in the Multi-Code format at 300 MHz, it serves as a universal replacement or upgrade for installations that use Multi-Code 300 MHz handheld transmitters. Typical applications include residential and light commercial door and gate systems where a stand-alone add-on receiver is needed to interface with push-button trigger inputs on the operator.
This receiver uses a 10-position DIP switch to set its code, matching the transmitter’s DIP code for simple, reliable programming without a learn mode. It provides a momentary dry-contact output to simulate a wall-button press and connects to the operator’s low-voltage control circuit and accessory power. The DC5100 works with common Multi-Code 300 MHz remotes such as Multi-Code 3089 and compatible Digi-Code transmitters in the 5000 series. An external antenna is typically included to optimize reception; mount the antenna away from large metal surfaces and motors for best range. Installation requires basic low-voltage wiring and observing standard safety practices, including removing power from the operator before making connections and mounting the receiver in a dry location or protective enclosure as required by the site conditions.
