  • Page 7: When To Use The Output Pullup Resistors

    • 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.
