How to wire the Ericsson IBR900 / IBR600 router for digital alerting

This article explains how to wire the Ericsson IBR900 / IBR600 router to send digital alerts to HAAS Alert’s Safety Cloud.

The IBR900 / IBR600 can be wired using one of three methods, depending on whether ignition sensing is used and which cable is available.

• Option 1: Use the 4-pin square power port (default)
  Use this option only if ignition sensing is not in use.
• Option 2: Use the GPIO extensibility cable
  Use this option if:
  • Ignition sensing (orange wire) is already in use
  • 4-Pin square power port wire is unusable for warning light activation
• Option 3: Use the GPIO exensibility dock w/cable
  Use this option only if the extensibility dock has been installed

Option (Use ONE Only)	Description	Pin-Out
	Connection (Option 1) Use the orange wire from the 4-pin square power port cable (Input / Pin 3). Connect the orange wire to the positive side of the vehicle's warning lights switch. If the orange wire is already used for ignition sensing, Option 2 or 3 must be used. R2R (if subscribed) will use the blue wire (Output / Pin 4).
	Connection (Option 2) Use Orange (preferred), yellow, blue, white, or green wires on the GPIO extensibility harness: Orange → Pin 7 Yellow → Pin 2 Blue → Pin 3 White → Pin 4 Green → Pin 5 Connect any one of these GPIO wires to the positive side of the vehicle's warning lights switch. R2R (if subscribed) will use one of the remaining GPIO 1, 2, or 3 (Pins 7, 6, or 5) wires.
	Connection (Option 3) w/Extensibility Dock Use orange (preferred), yellow, blue, white, or green. Orange -> Pin 5 Yellow -> Pin 6 Blue -> Pin 7 White -> Pin 8 Green -> Pin 9 Connect any one of these GPIO wires to the positive side of the vehicle's warning lights switch. R2R (if subscribed) will use one of the remaining GPIO 1, 2, or 3 (Pins 7, 6, or 5) wires.

Important Notes

• Only one wire is used to detect warning light activation
• Ensure connections are made to the positive side of the warning lights switch
• Always secure unused wires with heat shrink or electrical tape if using the extensibility cable
• If unsure which cable to use, contact HAAS Alert support for guidance
