System description
Using a CDB650 connection module (optional)
Optionally, the RFU6xx RFID interrogators can be operated at the access points via
a connection module. The connection module connects the RFID interrogator to the
power supply and, via a digital switching output, to the electronic access control system.
It helps to bridge extended distances between the RFID interrogator and the connections.
The RFID interrogator is connected to the connection module via a pre-assembled cable.
The connection module is wired to the power supply and control system via corresponding
terminals inside the housing.

As the connection module is generally mounted at a location that is not accessible to
outsiders, it is also ideally protected against tampering.
If the switching operations are not to take place directly in the RFID interrogator, but in the
connection module instead in order to provide increased protection against tampering, the
CMC600-101 cloning module must also be connected there. The cloning module supports
the connected RFID interrogator with two additional inputs and outputs.
