The CVT-OPTW allows multiple readers and panels to be connected together
The CVT-OPTW also allows systems with different voltage levels to be electrically
connected together.

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.
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 collector and will work with voltages
from 5 to 24 VDC. Depending on the system, pullup resistors to the higher voltage may be
required.
