Page 1 of 7 P/N: 01217-001 Rev. A
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.
