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.

Interfaces

The reader has the interfaces RS-485 and clock/data that can be used alternatively (Details see
Chapter 2. "Interfaces").
RS-485: When started up, the reader automatically identifies the RS-485 interface.
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 bus, a distributor with a 120 Ohm
terminating resistor (from A to B) must be installed in front of the reader.
For further information, refer to the description of the corresponding controller.
Clock/Data: To ensure reliable functioning, ensure that a possible extension of the 6 m connecting
cable does not exceed 200 m (Condition: no external interference voltage).
A JY(ST)Y 6x2x0.6 mm cable (DIN VDE 0815) can be used for extension purposes.
Attention:
Do not confuse the data
lines A and B, otherwise the
device will not function!
