PHYSICAL CHARACTERISTICS
PRISM TM2
The Prism TM2 is a custom built transceiver made for Teletrac. The device is a black ABS
plastic box roughly the same size as a small CD carrying case. Internally it consists of a GPRS
modem, a GPS receiver, a controller board and a SIM card. The GPRS modem and GPS
receiver are basically off-the-shelf devices. It’s the SIM card that
makes this product unique.
The SIM (subscriber identity module) card is a small electronic board
that contains the “personality” of the unit. The SIM is a programmable
card that can easily be moved from one unit to the next so that in the
event of hardware failure the card can be remove and placed in a new
unit without any reprogramming. SIM cards and the GPRS system run
on the GSM network which is considered to be one of the most secure
communication systems since both data and voice are encrypted to
prevent eavesdropping. See Section Two for more information about
how GSM, GPRS and SIM cards work.
In theory, the Prism TM2 should work about the same as a VLUplus. It
has been purposefully designed to have a similar wiring scheme and
to use the same installed peripherals. See Unit Five for installation
information.

ANTENNAS
The Prism TM2 uses a hidden combo antenna or roof mount combo antenna. In the future there
will be more antenna options once the physical connector has changed.

PERIPHERALS
MDT
The Prism TM2 is designed to use the same peripherals or accessories that the RF and CDPD
VLU and previous GPRS units uses. In addition to the same peripherals, the Prism TM2 currently
has two inputs and one outputs. Input 0 is configured to work with ignition on/off and inputs 1 &
2 allow for the connection of PTOs.
