Note:
The distance between the interface converter and the last foyer card reader
must not exceed 1000 m (installation cable J–Y(St) Y 2 x 2 x 0,6 mm).
Ensure the foyer card reader is correctly grounded.
Shielding may only be applied on one side.
The foyer card readers must only be connected
via the card reader connectors.
If the last foyer card reader on the RS 485 bus is a MINITER,
then for termination of the RS 485 bus, a terminal resistance of
250 ohms is always required (resistance is included in the scope
of delivery)
To enable the foyer card reader to read the cards, the back square
at the rear of the inner housing must be cut out.
