The AX11 card reader interface is capable of supporting Verkada Readers over RS-
485 and standard wiegand readers. The following table shows the wire types that are
recommended for use with AX11.
We recommend using one twisted pair for GND and VIN (power) and one twisted pair for the data (D0/D1 or
A/B). Wiring methods shall be in accordance with National Electrical Code, ANSI/NFPA 70.
Required Network Settings
With the AX11, you must use shield wiring.
Drain wire of the cable should be secure to the nearest grounding point, indicated with on the controller,
with a conductive M4 screw.
An Ethernet connection with DHCP must be used to connect the AX11 to the Local Area Network (LAN).
You also need to congure rewall settings to communicate with the AX11.
