1.5 Keypad Formats
• 8-bit burst (default)
• 26-bit Wiegand
The Keypad format can be toggled between 8-bit burst and 26-bit Wiegand using the
KeypadDataMode card that is provided with the keypad. Present this card within 60 seconds of power
up to toggle between states.
1.6 Cable Options
NOTE: On long cable runs, cable resistance causes a drop in voltage at the end of the cable run.
Ensure the appropriate power and current for your device is available at the device at the end of the
cable run. Heavier gauge cable reduces this effect.
NOTE: Keri does not recommend hot-plugging a Reader, RIM, or 4x4 into an NXT controller.

Remove power from the controller prior to connecting these devices.
