Using a VTAP reader for access control

There are two VTAP100 PAC (Physical Access Control) readers that support the technologies commonly used for access control:

• A VTAP100 Wiegand reader (VTAP100-PAC-W) can interface directly with a Wiegand controller, as a door or turnstile reader in an access control system.

• A VTAP100 RS-485/OSDP reader (VTAP100-PAC-485) will support the Open Supervised Device Protocol, as a Peripheral Device (PD) in secure communication with an Access Control Unit (ACU).

Read on about Using Wiegand or refer to Using OSDP for more about the use of a VTAP100 RS-485/OSDP reader. When OSDP is used, some of the Wiegand data manipulation described here may be needed, but the use of OSDP on VTAP readers is not limited to access control.
