The distance between the interface converter and the last foyer card reader can be a
maximum of 1000 m (installation cable J-Y(St) Y 2 x 2 x 0.6 mm).
The foyer card reader must be correctly grounded!
Shielding may only be applied on one side.
The connection between the foyer card readers may only be made via the connector strip
of the reader.
If the last foyer card reader on the RS 485 bus is a MINITER, the RS 485 bus must always
be terminated with a 250 Ohm termination resistor (resistor is included in delivery).
For flush mounting: At the rear of the housing, the angle bracket that the credit card hits
must be cut off. Only then is the credit card data read correctly.
