3. 2-Inch User Interface (Optional)
The 2-inch User Interface displays the status of communications to the MTU, (mobile transmitting unit). The MTU uses
GPS and at least one communication channel, (either GSM/GPRS or Iridium satellite) to send vehicle or equipment status
and position.
Connect the User Interface with the wiring harness (HN9040) as shown in the Wiring Diagram.
3.1 Operation
When power is applied your interface display will beep and the LCD will illuminate. To show that the MTU is running the
2-inch display will show one of the following messages:
1. “Wait” is the boot up message, which indicates the unit is trying to communicate with the MTU.
2. “Comm”
Indicates the MTU is running, has a GPS fix and has at least one communication channel open/available,
(GSM or Iridium).
