The ZK C3-100, ZK C3-200, ZK C3-400 controllers are configured on the settings panel of the corresponding objects AC ZK Controller C3-100, AC ZK Controller C3-200 and AC ZK Controller C3-400 which are created on the basis of the AC ZK Teco object on the Hardware tab of the System settings dialog window.

To configure the ZK Teco controllers, do the following:

1. Go to the settings panel of the corresponding ZK Teco controller.
   
2. From the Gate drop-down list (1), select the type of controller connection (see Configuring the connection via Ethernet standard or Configuring the connection via RS-485 standard).
3. In the Password field (2), enter the password for controller connection.
4. If the Ethernet connection type was selected, then enter the IP address of the controller in the IP field (3).
5. If the the RS-485 standard connection type was selected, then select the connection COM port number from the Address drop-down list (3).

6. From the Anti-passback drop-down list (4), select the mode of anti-passback operation:

   Mode	Description	Controller
   Disable	The anti-passback function is disabled	All controllers
   Readers of Door 1	The anti-passback function is enabled between the readers of Door 1	ZK C3-100, ZK C3-200
   Readers of Door 2	The anti-passback function is enabled between the readers of Door 2	ZK C3-200
   Readers of door 1, readers of door 2	The anti-passback function is enabled between the readers of Door 1 and Door 2 respectively	ZK C3-200
   Door 1 and 2	The anti-passback function is enabled between the readers of Door 1 and Door 2	ZK C3-200, ZK C3-400
   Doors 3 and 4	The anti-passback function is enabled between the readers of Door 3 and Door 4	ZK C3-400
   Doors 1 and 2, doors 3 and 4	The anti-passback function is enabled between the readers of Door 1, Door 2, Door 3 and Door 4	ZK C3-400
   Doors 1, 2 and doors 3, 4	The anti-passback is enabled between Door 1, 2 and Door 3, 4	ZK C3-400
   Door 1 and doors 2, 3	The anti-passback is enabled between Door 1 and Door 2, 3	ZK C3-400
   Door 1 and doors 2, 3, 4	The anti-passback is enabled between Door 1 and Door 2, 3, 4	ZK C3-400

   
   

7. From the Interlock drop-down list (5), select the mode of doors interlocking:

   Mode	Description	Controller
   Disable	The interlock function is disabled	All controllers
   Door 1 and 2	Doors 1 and 2 are interlocked mutually	ZK C3-200, ZK C3-400
   Door 3 and 4	Door 3 and door 4 are interlocked mutually	ZK C3-400
   Doors 1, 2 and 4	Door 1, door 2 and door 4 are interlocked mutually	ZK C3-400
   Doors 1 and 2, doors 3 and 4	Door 1 and door 2 are interlocked mutually, door 3 and door 4 are interlocked mutually	ZK C3-400
   Doors 1, 2, 3 and 4	Door 1, door 2, door 3 and door 4 are interlocked mutually	ZK C3-400

   
   

   To open one of the interconnected doors, the other interconnected doors in the group must remain closed. This means that in a group of interconnected doors, only one door can be opened at a time.
