TrimTrac ProE Locator Technical Manual v2.0e 73
1. Inspect the spring loaded connectors on the TrimTrac ProE to confirm that
none are damaged or misaligned.
2. It may be helpful to clean the contact pads on the Provisioning Module,
especially if the Provisioning Module has been in service for an extended
period of time. A pencil eraser has proven effective in removing any
residue or oxidation that may have built up.
3. When inserting the Provisioning Module into the TrimTrac ProE, make
sure all four corners of the Provisioning Module are completely and
securely snapped into place. If not securely snapped into place, then there
may not be good contact between the Provisioning Module and the
TRIMTRAC PROE base.
4. Start Hyperterminal and open a new connection using the recommended
settings. Type ATI and see if you a response. If no response, then
squeeze the Provisioning Module and TRIMTRAC PROE together near
the end where the connectors mate. You may get a RDY response or
string of characters if there is an intermittent connection.
5. Inspect the bottom of the Provisioning Module PCB. There are several
through-hole leads near the corner with the bar code label. If any leads are
protruding up through the solder, then perhaps they need to be trimmed if
you received an early version of the provisioning module built before the
lead trimming process had been fine tuned..
No Data Communication with Base
If the TrimTrac ProE is not communicating with the server application as
expected, do the following:
1. Confirm that a data-enabled SIM (SMS or GPRS) is inserted in the
unit and that the hold down latch is pressed all the way down and
securely holding the SIM card at all four corners.
2. The TrimTrac ProE is specified to work with 3.0 Volt SIMs only. If a
5.0 Volt SIM is used, the device may work with SMS, but it will NOT
work with GPRS.
3. Confirm proper provisioning, including Unit ID, SMS Destination
Address, Security Password, and, if needed, SIM PIN. Make sure the
correct APN, Username and Password are used for GPRS;
4. Verify that the unit has its application parameters configured as
desired. Pay particular attention to the Report Delay Flag, QUERY
Timeout, T5, and TRANSMIT Timeout, T3, settings. Default settings
for QUERY Timeout, T5, and TRANSMIT Timeout, T3, are
recommended.
5. Set the Diagnostics Mode to “1=Enabled” and observe the LED to
confirm that the unit properly enters the TRANSMIT and QUERY
states.
