Connecting a reader to the RF120C

NOTICE
Correct usage
When connecting non-specified devices to the RF120C, it is possible that the connected
device may be destroyed.
A pre-assembled cable therefore permits the optimum and simple connection of the reader.
The standard version of the connecting cable is available in lengths 2 m, 5 m and 10 m.
Figure 3-2
To connect the cable, open the lower door in the housing as shown in the figure and connect
the reader using the D-sub cable and the 9-pin D-sub socket of the communications module.
At the top right behind the upper door in the housing of the module the version is printed as a
placeholder "X". You require the version if you have questions for Support. In the example "X
2 3 4", the "X" is a placeholder for the version "1".
Note
Pulling and plugging the D-sub is allowed when the power is on. After connecting a new
reader, the "Reset_Reader" block must be called.
