Communication Status LED Blinking
Problem: Orange Communication LED Blinking
If the Orange COMM LED continues to blink slow (1 blink every 2 seconds), this indicates one
of two possible conditions:
•
The location of the trailer is not within cellular coverage. All TT150 messages will be
queued and then transmitted once the trailer is relocated to an area where cellular
coverage is available.
•
The TT150 terminal is not properly provisioned for the cellular network, contact the
Omnitracs Hotline at 800-541-7490 to check the provisioning of the terminal.
If the Orange COMM LED continues to blink fast (1 blink per second), this indicates the trailer
is in cellular coverage but the Omnitracs network server is not responding. This could be a
temporary condition – possibly during a system maintenance window. If the condition persists,
call the Omnitracs Hotline at 800-541-7490 to check the terminal’s provisioning status and
TT150 system availability.
If the Orange COMM LED alternates from solid to blinking fast, this indicates one of two
possible conditions:
•
The TT150 was recently installed and did not receive power long enough to get fully
registered. Reapply power to the 7-way connector for five minutes. If the condition
persists, check the fuses and the white, blue, and brown wire connections at the trailer’s
7-way connector and reapply power to the 7-way connector for five minutes.
