Installation Note
Make the connections from the reader to either the Controller 3000-8R or 3000-4R
as shown:
Note: Within each group, you cannot mix Cardax IV Readers with Wiegand Readers.
This is because connecting 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.
