Connection diagram
A plug has been soldered to the cable of the reader at the factory especially for test and
premounting sets. For the final installation, it usually has to be cut off.

Clock/Data and RS-485 interface
The reader has the interfaces
up, the reader automatically identifies the interface that is in use.
Clock/Data:
To ensure reliable functioning, ensure that a possible extension of the 6 m connecting
cable does not exceed 200 m. A JY(ST)Y 6x2x0.6 mm cable can be used for extension
purposes.
RS-485:
The reader can be used remotely at a distance of max. 1200 m. We recommend
using a Cat 5 connecting cable.
If the reader is the last user on the RS-485 module bus, a distributor with a 120 Ohm
terminating resistor (from D to D*) must be installed in front of the reader.
For further information, refer to the description of the corresponding central control
unit.
Attention:
Do not confuse the data
lines A and B, otherwise the
device will not function!

Synchronization
In order to prevent densely packed readers from affecting one another, they must be connected to
one another via the "Synchronization" line (black). Up to 4 readers can be synchronized in this
manner.
Synchronization is required at a distance of
The transponder that is identified first has priority during the read process. The other readers
involved are inactive. After a period of 5 sec. they are reactivated.
