TrimTrac 1.5 Configuration
Introduction
Configuration is the process of setting the operational and communication parameters of
the TrimTrac 1.5. Most, but not all, of these parameters can be set or changed over the
air; however, certain non-default entries, such as the Unit ID, Security Password and SIM
PIN, can only be entered or changed when the TrimTrac 1.5 is connected to a PC via a
Provisioning Module.
Personnel without prior configuration or provisioning experience should familiarize
themselves with the TrimTrac 1.5 operation and application characteristics as more fully
described in the TrimTrac State Machine chapter beginning on page 52.
Provisioning Mode and Equipment
Before a new TrimTrac 1.5 can communicate for the first time, it must be properly
configured. This entails substituting the Battery Pack or other optional modules with a
Provisioning Module and then connecting it to the USB 2.0 port on a Microsoft Windows
(2000, XP)-based PC. Use of USB 1.0 ports or hubs is not recommended. Some laptop
computers may not have enough power available on the USB port to power Provisioning
Module, especially when the laptop is operating on batteries. If a laptop is used to
provision the TrimTrac 1.5, it is best to have the laptop connected to AC power.
Alternately, if you must use a battery-powered laptop to configure the TrimTrac 1.5, it is
best to first insert the Provisioning Module into the TrimTrac 1.5 base, connect the
Provisioning Module to the USB port and THEN power up the laptop.
Microsoft’s HyperTerminal is then used as the primary programming interface to send
the proper AT Commands. The AT Commands are described in this section and must be
used the first time the TrimTrac 1.5 is provisioned. Text fields need to be enclosed in
quotation marks “_”.
Provisioning Set-up
Before a TrimTrac Provisioning Module can be connected and used with an USB 2.0-
equipped Microsoft Windows (2000, XP)-based PC, the appropriate USB 2.0 drivers and
HyperTerminal program must be installed on the PC.
FTDI Driver Loading
The Provisioning Module uses an USB 2.0 interface chip from Future Technology
Devices International Ltd. (FTDI). The easiest way for HyperTerminal to
communicate with the Provisioning Module is to download and install the
appropriate FTDI driver on the PC on which HyperTerminal will run.
These Windows (2000, XP, ME) drivers are available from FTDI for download
and use at:
