MRR - MRRF - MRRE
GENERAL INFORMATION
The MRR receiver was designed to be connected to access control central units as a radio reader. The code received from the transmitter is
re-sent to the terminals according to the format and protocol selected by means of the programming dipswitches.
The formats available at the output are those most commonly used in access control systems and make it possible to interface the MRR
with not only the M5000 control units, but also with the majority of the control units on the market.

SELECTION OF OUTPUT FORMAT AND PROTOCOL
CHANNEL ADDRESS
The MRR receiver can be operated by one or more push buttons of the transmitters by
means of the channel address dip-switches (see figure).
OUTPUT LEVEL SELECTION
A jumper on the circuit (see figure makes it possibile to select the level
of the output signals in the wiegand, Dataclock and
TTL formats.
CONNECTIONS
The EN terminal must be connected to GROUND to enable the receiver.
The cable recommended for the connection of the MRR reader is STP class 5 or FTP class 5 or better.
