Cardax IV Reader
Note: Within each group, you cannot mix Cardax IV Readers with Wiegand Readers.
This is because connecng one Wiegand reader requires all four pins on plug PB.
For example, if you connect a Cardax IV Reader to Port 1 of Group 1, Port 2 of Group
1 can only connect to another Cardax IV Reader.
