WIEGAND
The Wiegand and Magstripe ISO7811/2 (clock & data) interface share the same
connections. This means that only Wiegand or Magstripe can be used and not both
simulaneously.
Wiegand connections:

Ground (0V)
SHIELD
Shield connected to DC-ground.
Message format:
The Wiegand output format is determined by the programming format of the
credential. MACE Wiegand credentials will automatically generate a Wiegand
message. If the credential is not programmed in Wiegand format, you may configure
the message output format as described in chapter 4.5.2.
Make sure to order the correct credential programming format if you want to use the
Wiegand or Magstripe interface. See also the MACE how to order guide (HTOG) for
more information.
