The Pulsar 8866TC-OCS garage door operator transmitter features open, close, and stop functions for six distinct door operators. This transmitter serves as a replacement for the older, discontinued Allstar, Allister, and Pulsar transmitters that operated on the 318FL and 318MHz frequencies. It is compatible with 318MHz receiver models 833, 833T, 8833, 8833T, ADX8833, PDX8833, and MVP receivers.

This transmitter features eight trinary switches, each with three positions, that must be matched with your receiver to control the open, stop, and close operations.
