2.2 Troubleshooting
1.
No LED is on after connection of the USB-GT interface to the
host:
Check that the host is powered up.
Check that the host’s USB-ports are operational.
Check connection at both cable ends.
2.
Green LED light, but yellow LED is dark:
A defect in the interface is possible. Please contact your ser-
vice address for repair.
3.
Yellow LED does not blink after connecting the device and is
not identified by the host:
Check that the device is operational and that the connecting ca-
ble is connected correctly. Disconnect the cable between the
host and the USB-GT interface and wait a few minutes.
Re-connect the cable between the host and the USB-GT N in-
terface. The connection should now be active and the yellow LED
should blink.
