DoorKing has discontinued manufacturing the 8055-080, and 8055-081, MicroPlus receivers. The processor used in these receivers has been discontinued by the manufacture.

The blue 8040-080 receiver (pictured) is the replacement for the 8055 receivers. The 8040 can be programmed to operate with either the MicroPlus, or MicroClick transmitters, and can be set for stand-alone operation (relay contact closure), or will output the transmitter data in wiegand format.
