The CVX-OPTW is designed to provide isolation between different Wiegand signal
sources.
The CVX-OPTW allows multiple readers and panels to be connected together.
The CVX-OPTW also allows systems with different voltage levels to be electrically
connected together.
The CVX-OPTW may be cascaded to connect additional readers or panels to be
connected.

If voltage levels other than 5 volts are required at the output, then do not connect the
internal pullup resistors. The outputs are now open collectors and will work with voltages
from 5 to 24 VDC. Depending on the system, you may need pullup resistors to the higher
voltage.
Previous versions of the CVX-OPTW had internal pullup resistors connected to the output
ports. These pullup resistors were wired to the +5VDC supply. This newer version provides
the option of connecting the pullup resistors in order to allow connection as a true open
collector output.
With the pullup resistors connected as indicated in the above diagram, the new OPTW is
equivalent to the previous version.
