System Component Overview
TT150 Components
TT150 Terminal
TT150 terminal with microprocessor, cellular modem, rechargeable internal battery pack,
cellular antenna, and GPS antenna. Attached to the terminal is a cable for recharging the
TT150 battery pack when the trailer is connected to a tractor.
The terminal is designed according to industry environmental specifications. The system
allows over-the-air (OTA) reprogramming of the terminal’s on-board firmware.
The TT150 terminal also has two LEDs for verifying cellular coverage and a GPS fix when
active.
The trailer operator (truck driver, loader, or unloader) does not need to access the terminal.
It should be mounted in a safe and secure place on the trailer.
Internal TT150 Battery
Internal to the TT150 terminal housing is a lithium ion rechargeable battery that is used
when the trailer is not connected to external power (i.e. not connected to a tractor). A
fully charged terminal will work for 90 days sending one message/position a day when
not powered. The battery will recharge when power is applied to the 7-way. The battery
is not serviceable.
Note: The TT150 does not ship fully charged. It is recommended that the battery be
fully charged immediately after it is installed to provide the best messaging experience.
TT150 Power Cable Assembly
The TT150 power cable assembly is permanently attached to the TT150 terminal enclosure.
The power cable assembly contains fuse holders, which are separate from the power cable
assembly to ease routing of the cable assembly and make installation of the TT150 terminal
easier.
