System Verification
TT150 Initial Installation System Verification
Checking the TT150 Terminal LEDs
1.
Apply power to the trailer’s 7-way. When the TT150 terminal gets power it will wake up
and attempt to get GPS and cellular signals. In most cases, a truck with its key in the
ON position and the pig tail connected to the trailer will supply 12 volts of power to the
7-way.
Note: When powering up a TT150 terminal for the first time, it is important that the TT150
terminal gets steady power for more than three minutes for it to establish a connection to
the Omnitracs network.
2.
Check the Communication and GPS LEDs to confirm the device is able to communicate
and get a GPS fix. Both the green GPS and orange communication LEDs should be
solid when the trailer’s 7-way is receiving power.
•
If both LEDs are solid, proceed to the next section, Using the TT150 FST.
•
If both LEDs are off, refer to Chapter 8: TT150 Status LEDs are Off.
•
If the green GPS LED is blinking, refer to Chapter 9: GPS Status LED Blinking.
•
If the orange communication LED is blinking, refer to Chapter 10: Communication
Status LED Blinking.
