Proximity Readers for legacy systems
• Mounts on and connects directly to
NXT Controller
• Also mounts on and connects to NXT4X4 and GIOX Input/Output Expansion
Modules for applications where

access control access control functions
are moved closer to the door
Keri’s NXT-RM3 Reader Interface Module is designed to make it easy to connect reader technologies with industry
standard Wiegand output to NXT Controllers. It also allows connection of Keri MS Series Proximity Readers, most
commonly used for legacy systems where PXL-500 Controllers are also in place being used with KC-10X, MT-10X, or
PKT-10X credentials.
The NXT-RM3 securely plugs directly onto an NXT Controller or an NXT-4X4 or GIOX I/O Expansion Module with
excellent mechanical and electrical integrity. The option to bring the reader terminations to the I/O modules
provides substantial savings in wiring costs because door functions can be located closer to the reader/door, with
only 4 wires required to be cabled to centrally located controllers.
