Test the reader / Commissioning
Apply power (the green LED indicates power) and present a valid creden-
tial. The light ring should flash and the sounder should produce a short
tone indicating a successful read. If the Host system is connected the light
ring and sounder should follow the functionality of the Host system.

Cable specification
– The reader is supplied with 2 m (6 ft.) of shielded, 8-conductor
0,14 mm² (AWG 26) cable which may be extended with the length
and size of cable listed below.

Wire assignments
The connection must be carried out in de-energized state! Risk of
damage!
To ensure reliable functioning, ensure that a possible extension of the 4 m
connecting cable does not exceed 152 m (condition: no external voltage
supply unit is required). For extension purposes up to 152 m an additional
JY(ST)Y (6x2x0.6 mm) cable can be used.
The reader can be used remotely for extension purposes at a distance of
max. 1220 m. We recommend using a Cat 5 connecting cable (condition:
an external voltage supply unit for the reader is required).
In general, by use of RS-485 interface:
When the reader is the last user
on the RS-485 bus, a 120 Ω end-of-line resistor (from TRX+ to TRX-)
must be installed in front of the reader. For further information, refer to the
description of the corresponding controller.

Caution
Floating communication lines may cause spurious emissions, invalidating
certification. Ensure all communication lines are properly biased and ter-
minated.
Input Hold line
This input makes it pos-

Operation
When a credential is read successfully, the light ring lights briefly, the
sounder sounds a short tone and the credential associated code is sent
to the Host system.
The light ring and sounder are also controllable by the Host system.
Reader output formats are determined by the personalization of the cre-
dential and/or configuration of the reader; on SmartTech and MultiTech
readers the behaviour of the light ring and sounder can be modified
through configuration.
