Escalate to P2 Smart Carts and include the smart cart ID and a screenshot of the response.
NOTE: The connector is on the top shelf of the smart cart, and is labeled with “ZIP” heat shrink or “DROID” heat shrink.



green activity light blinking or solid?
1. The board is powered.
2. The Ethernet cable is connected between the NEO and the T1 adapter board.
3. The SLV jumper has been removed. The image below shows the correct jumper setup with the SLV jumper removed.

4. The twisted pair is connected to the vehicle and the T1 board.
5. The twisted pair polarity is correct. If in doubt, try swapping the wires if it has been moved.
6. The twisted pair is twisted.
- If the twisted pair looks more like two loose wires, there might be too much noise on the line (https://en.wikipedia.org/wiki/Twisted_pair).
1. The box is powered. You should see a red PWR light in the front.

2. The Ethernet cable is connected between the NEO and the T1 Converter.
3. The master/slave switch is set to master.

4. The twisted pair is connected to the asset and the T1 board.
5. The twisted pair is twisted.
- If the twisted pair looks more like two loose wires, there might be too much noise on the line (https://en.wikipedia.org/wiki/Twisted_pair).
