Abstract

A control unit for an EAS system is described, the unit comprising a controller area network (CAN) communication device operatively coupled with a remote communications link. A master control (MC) module interfaces the CAN device and the remote communications link. Machine readable executable instructions reside on a digital signal processor (DSP). The unit further includes at least one system module having a targeted feature within the EAS system.

Claims

1. A control unit for an EAS system, the unit comprising:

a controller area network (CAN) communication device;

a remote communications link;

a master control (MC) module;

machine readable executable instructions residing on a digital signal processor (DSP); and

,

at least one system module, said at least one system module comprising communication between the MC module and at least one AC power line monitoring device.

2. The unit of claim 1, wherein the remote communications link comprises a POP3/SMTP protocol.

3. The unit of claim 1, wherein the at least one system module comprises communication between the MC module and at least one tag or label deactivation device.

4. The unit of claim 3, wherein the communication between the at least one system module and the MC module transfers tuning information about the deactivation device.

5. The unit of claim 3, wherein the communication between the at least one system module and the MC module transfers deactivation quantity information.

6. The unit of claim 1, wherein the at least one system module comprises communication between the MC module and at least one antenna of the EAS system.

7. The unit of claim 6, wherein the communication between the at least one system module and the MC module transfers deactivation information.

8. The unit of claim 1, wherein the at least one system module comprises at least one manual switch for activating and deactivating the EAS system.

9. The unit of claim 1, wherein the at least one system module comprises an interface between at least one computer and the CAN communication device.

10. The unit of claim 1, wherein the at least one system module comprises communication between the MC module and at least one security device.

11. The unit of claim 1, wherein the at least one system module comprises communication between the MC module and at least one relay.

12. A control unit for an EAS system, the unit comprising:

a controller area network (CAN) communication device

a remote communications link;

a master control module;

machine readable executable instructions residing on a digital signal processor (DSP) interconnected with the CAN communication device;

a computer interface module (CIM);

a transmit control module (TCM);

a deactivator module (DEACM);

an EAS module (EASM); and

,

a power monitor module (PMM).

13. The unit of claim 12 further comprising a security action module (SAM).

14. The unit of claim 13, wherein the SAM further comprises at least one audio or visual alarm device.

15. The unit of claim 12 the PMM further comprising at least one AC power line phase monitoring device.

16. The unit of claim 12 further comprising an external relay module (ERM).

17. The unit of claim 16 the ERM further comprising at least one external relay operatively communicating ingress or egress to an area.
