Cable Options
RS-485 bus runs can daisy-chain together an NXT-4x4 and NXT-Reader on one line. The total cable run distance should
be less than 500 feet from the NXT controller for runs with two Readers or one Reader and one 4x4, and less than 1,000
feet for single Reader runs.
NOTE: Cable resistance causes a drop in voltage at the end of long cable runs. 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 affect.
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.
