Possible Causes and Solutions
There may be insufficient current on the constant power connection.
Check that connection. Ensure the source wire is capable of supplying 5 amps.
There may be a loose or insufficient chassis ground. Inspect the ground
connection to ensure it's tight and it's in a location free of paint or rust.
There may be an issue with that specific USB port. Try connecting to a different
USB port on the laptop.
The laptop may not be detecting the device. Open Device Manager on your
laptop. Verify that "Remote NDIS6 based Device" shows up under "Network
Adapters".
The ER-SF1 may not be detecting Ignition from the brown wire. Check the wire for
damage. Check the wire with a voltmeter for 12V/24V with the ignition on. Check
the vehicle fuse for that circuit.
There may be an issue with Windows Firewall. Plug the device in again and verify
that the Lytx Installation Tool is allowed through Windows Firewall.
There may have been a momentary issue. Try creating a manual event and then
doing a forced check-in.
To manually create an event, push either of the blue manual record buttons on
the ER-SF1. The LED status lights on the ER-SF1 will light up green one-by-one
from the left to right until all are lit, indicating the event has been created.
After the event is created, hold one of the manual record buttons for 10 seconds
to attempt a forced check-in to Lytx. The LED status lights will light up and blink
one-by-one from the left to right until all are lit, indicating the check-in was
successful.
The device may be in an area without reception. Bypass this for now by checking
the "Known Issue Bypass" box. Re-test this connection when the device is in a
location with better reception.
