Introduction
Access Unit Wireless 3000-U981-02
The Access Unit Wireless (AUW) is a module for the EMKA Electronics
system and has to be controlled with a Control Unit (CU).
It communicates with the wireless Agent E handle (Agent) over radio
frequency (868 MHz Europe and 922 MHz USA/SGP) and can control up
to 1200 Agents.
Features
• Wireless Unit to administer Agent E Wireless in combination with Control
Unit
• Administration of up to 1,200 doors in a wireless network via access
units and Control Unit
• Unique Network ID of each MAUW prevents cross communication
between Agents of different systems
• Max. 16 Access Units Wireless per Control Unit can be added to increase
communication area
• Frequency 868 MHz (version Europe) or 922 MHz (versions USA,
Singapore)
• Two Independent power inputs for redundant supply
• Power distribution through CAN and RS-485 for easy installation
• Configuration and monitoring is managed by the Control Unit

System Overview
The CU has to be connected over CAN Bus with the AUW, this AUW is
the Master Access Unit Wireless (MAUW) and manages the whole
information flow between handles and CU.
Depending on the shape and size of the area that has to covered, the
communication range can be extended, by adding additional AUWs to
the MAUW. Up to 15 additional RelayAccess Units Wireless (RAUWs)
can be connected to the MAUW.A RAUW differs from a MAUW as it
works only as range extender. Since they don't work as modules for the
CU they are not connected via the CAN Bus, the MAUW connects to the
RAUWs over a RS-485 cable connection.
They are connected as a chain and for clear internal identification the
hardware switch on the back of eachAUW is set on a different position.
(The MAUW has to have this switch on position 0). The whole logic about
which RAUW respond to which Agent and which is accepting requests is
done inside the MAUW and does not affect the CU.

In addition to avoid unwanted cross communication between CU
systems that are close to each other the MAUW binds each registered
Agent to his Network ID. A bound Agent refuses to communicate with
other CU/MAUW systems.
To increase reliability an AUW is equipped with a redundant power
supply, to ensure power.
