4, 5, and 6; find the wiring diagram that matches your application and set up a bench test accordingly. In many applications, the access control equipment is already installed and a bench test is not practical. In these applications, install the CVX-OPTW with the existing access control equipment and test the system thoroughly.
The wiring diagram below shows how to connect two Wiegand readers to one access control panel Wiegand port, using the CVX-OPTW to electrically isolate Reader 1 from Reader 2 and the access control panel while passing the Wiegand signals from both readers to the access control panel.
The wiring diagram below shows how to connect one Wiegand reader to two access control panels, using the CVX-OPTW to electrically isolate the Wiegand reader and Access Control Panel 1 from Access Control Panel 2 while passing the Wiegand signals to both access control panels.

• If the voltage levels of the Wiegand device(s) are below 4.4VDC while it is not connected to other devices, they the problem lies with that device and not the CVX-OPTW. This may be able to be recovered using external pullup resistors. Connect a 1K to 2K through-hole resistor to the low data line and a 5VDC output.
