RS-485 Cable Requirements
RS-485
bus runs can daisy-chain together an NXT-4x4 and NXT-Reader on one
line. The total cable run distance should be no more than 500 feet from
the Intelliprox Blue controller for runs with 4x4s and no more than 1,000 feet for reader-only runs.

To meet CE and C-tick regulations, the length of the controller power line can be no longer than
3 Meters (9.85 feet).
- Use
the shortest possible path from earth ground point to PCB. Connect the
earth ground only to the designated pin on the terminal block. This is
important as all transient protection for the unit is made through this
earth ground connection. For unit protection, the earth ground
connection should always be made first.
- Values listed are minimums. Individual input and output devices may have more specific
requirements.
Notes: - The
Lock Output relay may require a heavier gauge of wire depending upon
the current demands of the lock and the length of the lock wiring run.
- 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 effect.
- Keri does not recommend hot-plugging a Reader, RIM, or 4x4 into an Intelliprox Blue controller.
Remove power from the controller prior to connecting these devices.
