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. It supports the WIEGAND, I2C or RS 232 interfaces of the connected reading units. It is equipped with a controlling microprocessor x51 and two subordinate processors which ensure communication with external reader heads. When it comes to operation, it can work in an online mode, with the ability to switch offline in case communication problems appear.

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.
