When the Wiegand Output function is used, TTL Output wire is changed to Wiega
nd Data 0 and Chime Bell Output wire to Wiegand Data 1 Output wire. Therefore,
you can't use those functions. In addition, because TTL Output wire is changed to
Wiegand Data 0 Output, you can't initialize the 100W/IP100W using the wires.
(You can use those functions again when setting SW1 and SW2 to the default stat
e.)
