Customer support link 
This control unit is used for connection into the WIS access system. Its construction makes it designated for installation into the lower ceiling with an ability to connect two reading units. For the dragON technology it supports connection of reader heads with the RS 485 interface. It is equipped with a controlling microprocessor x51 and it is able to connect up to 8 reader heads WEGA of the KRBox type or up to 8 APERIO HUBs. It also contains new diagnostic LED diodes which check the functions of the functional departments of the reading unit. When it comes to operation, it can work in an online mode, with the ability to switch offline in case communication problems appear.

Inputs/Outputs
The control unit contains predefined inputs and outputs. Their function is apparent from the connector description J4. The active state of the inputs is given by the configuration of the control unit, and configuration can only be done from the configuration utility. While using the outputs (relay contacts) and controlling the charge of an inductive character the contacts must be connected correctly to the control unit. The positive pole of the controlled charge always must be connected to the NO or NC contacts. While controlling the electromagnetic locks the safety diode must be connected in reverse direction. .
