NXT-6RK Proximity Reader and Keypad
Installation Guide
The Keri NXT-6RK is a keypad reader typically used for card + PIN dual verification applications. It
transmits keypad data in either 8-bit burst (default) or 26-bit Wiegand formats and can be used as a
keypad-only device. Since the NXT-6RK communicates via Wiegand format it requires an NXT-RIM
for operation.
