Additionally, some Wiegand access controllers are not compatible with the non-standard Wiegand interface. Additional hardware, such as the OPTW-200, is required to parallel hybrid data interface readers with a standard Wiegand interface or connect a non-standard Wiegand reader with an incomplete Wiegand access controller.
OPTW-200 Manual - Bench Testing When installing the OPTW-200 with new access control equipment, bench testing is recommended. Refer to the wiring diagrams on pages 5, 6, and 7; find the wiring diagram that matches your application and set up a bench test accordingly.
The wiring diagram below shows how to connect one hybrid Wiegand/OSDP reader to one access control panel. The OPTW-200 is used to standardize the hybrid Wiegand interface; this is needed when the non- standard Wiegand reader cannot communicate with the access control panel.

1 Hybrid Wiegand/OSDP Reader and 1 Standard Wiegand Reader to a Panel Wiring Diagram The wiring diagram below shows how to connect in parallel one hybrid Wiegand/OSDP reader and one standard Wiegand reader to one Wiegand port on the access control panel. The OPTW-200 is used to standardize the hybrid Wiegand interface.

The wiring diagram below shows how to connect two hybrid Wiegand/OSDP reader to one access control panel. The OPTW-200 is used to standardize the hybrid Wiegand/OSDP interfaces. This setup may be used in applications such as high/low readers at vehicle gates, and in/out readers at building entrances.
The troubleshooting steps below assume 5VDC Wiegand devices Common ground connections: • The OPTW-200 must have a common ground with the Wiegand reader and Wiegand access controller. • The common ground is landed on the Ground (GND) pin on the J1 header.
