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
Opening the doors in the housing of the RF120C
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.
