Multiple Wiegand Reader Connection
Multiple reader mode allows the connection of 4 Wiegand reading devices controlling 2 doors each with entry/exit
readers.
In multiple reader mode, the secondary reader has all connections wired to the same port as the primary card
reader, with the DATA 1 connection wired to the opposite reader connection DATA 1 input.
The reader that is multiplexed into the alternate reader port will operate as the
exit
reader, and the normal reader
connection operates as the
entry
reader.
