5. If you wish to view what you type on the HyperTerminal Screen, click on
File, Properties, Settings, ASCII Settings and checkmark the “Echo Typed
Characters Locally” box. Click “OK” to close each panel.
6. To check whether you have successfully connected the TrimTrac 1.5 and
Provisioning Module to HyperTerminal, type:
AT+CTKC?
7. Assuming the factory default configuration has not been previously
changed, the following response should appear:
AT+CTKC=43200,300,120,900,60,168,20,0,0,1,0
OK
8. You are now ready to begin provisioning the TrimTrac 1.5(s) by typing
the AT commands described in the following sections.
WARNING:
Before inserting a Vehicle Adapter or Control Module into a TrimTrac base
unit:
A) Connect the red (+) and black (-) wires to a 9-32 VDC power source and
install a 100k Ohm resistor across the yellow wires; OR
B) Set the TrimTrac MPA Mode to “1=Disabled”.
FAILURE TO DO EITHER OF THESE WILL CAUSE THE TRIMTRAC
1.5 TO IMMEDIATELY ACTIVATE A MEDIUM PRIORITY ALERT
AND BEGIN TRANSMITTING NOMINALLY EVERY 2-3 MINUTES
UNTIL AN ACKNOWLEDGEMENT IS RECEIVED.
9.
When complete, reinstall the Battery Pack with four “AA” batteries or, if
used, the Vehicle Adapter or Control Module.
Configuring Multiple Units
If multiple TrimTrac 1.5s need to be configured, then you can send the units text
files with the desired settings rather then typing individual AT commands. To
configure HyperTerminal to send text files to the TrimTrac 1.5, select Echo and
set the line delay to 500 milliseconds from the HyperTerminal ASCII Setup panel
under File, Properties, Settings.
