3.0 OPERATING PROCEDURES
3.1 Configuring the LTCA Software for use with the TRM
The TRM can be used with a PC using the Vanguard LTCA software. Follow the steps below to
properly connect the TRM and configure the LTCA application to recognize the unit.
a. Install the LTCA software (please see the LTCA software user’s manual for details).
b. Connect the TRM to the PC by connecting a USB cable from an open USB port on the PC
to the unit’s “USB PC” port.
c. Turn on the power on the TRM.
d. If this is the first time you are connecting the unit to the PC, Windows will recognize it as
a new device and automatically install necessary drivers. If using Windows XP, you may
be prompted to install drivers. Select the automatic installation option and Windows will
locate the generic drivers necessary.
e. Please note that although the unit is connected via USB, it uses an internal serial
interface to communicate with the PC. As such, it will appear in the windows Device
Manager as a USB Serial Port. Open the Device Manager from the Windows Control
Panel and note the COM port number. For example, in the installation shown below, the
TRM is shown as COM10 (USB Serial Port).
