The Verkada AC41 is capable of supporting Verkada Readers over RS-485 and standard Wiegand readers. The following diagram shows the wire types that are recommended for use with the Verkada AC41.

We recommend using one twisted pair for GND and VIN (power) and one twisted pair for the data (D0/D1 or A/B).

If you are using shielded wiring:

  • Connect one end of the drain wire into the GND input of the AC41 cassette.
  • The drain wire and the GND wire should simultaneously share the COM [Common] port on the cassette.
  • The other end of the drain wire shouldn’t be connected to anything.

Here's an article that will walk through the actual installation.
