Wiegand port wiring
Wiegand input wiring
The following figure shows how to cable the wires of the “Wiegand In” port of the
terminal for Wiegand protocol. This is used, for instance, to connect an external card
stripe reader to the MorphoAccess® VP MD terminal.

If pull-up’s to 12V have been added on D0_IN and D1_IN inputs on a
previous installation with a MorphoAccess® 500 Series terminal, these
resistors must be removed to avoid any damage to the MorphoAccess® VP
MD terminal.
