This article explains how to wire the Ericsson IBR900 / IBR600 router to send digital alerts to HAAS Alert’s Safety Cloud.
Warning: When using a GPIO extensibility cable, DO NOT leave unused wires exposed. Cap or tape off unused wires to prevent electrical shorts or damage.
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 extensibility 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.
