have been. Verifying checksums helps avoid wasted time spent evaluating invalid
messages.
Out of Sequence Messages
Regardless of which protocol (SMS, TCP/IP or UDP) is being used, messages
received by the server application may be received out of sequence. If Automatic
Message Log Dump is enabled, and the device left and re-entered GSM coverage,
then the device will transmit messages logged while outside of GSM coverage
after GSM has been re-established. In so doing, messages will be received by the
server application out of sequence. When using UDP or SMS, there is no
guarantee that messages will be received in the same order transmitted by the
TrimTrac ProE.
Updating Firmware in the Field
You can upload new firmware from a PC or laptop connected to the Provisioning
Module. For more information on updating firmware in the field, please consult
with your Trimble technical support representative.
LED Indicator
The LED indicator is useful for diagnosing problems. For more information, see
LED States, page 138. If you detect a problem, then have the TrimTrac ProE
inspected by qualified service personnel.
Responding to Query or Set Data Messages
The TrimTrac ProE processes and, except as noted below, responds immediately
to any data message that it receives while in the QUERY state. It does not need to
cycle back through the State Machine before a response is sent back to the server
application unless the response requires a new position fix.
The TrimTrac ProE, however, will not respond to data messages:
1.
that are invalid (i.e. incorrect format, checksum, Unit ID, Security
Password and, if used, SIM PIN), or
2.
that are SET_ALERT_STATE messages in which a priority alert status is
set “0=Clear” but the underlying condition that triggered the original alert
message has not been returned to its “normal” condition.
The configuration of the TrimTrac ProE can be changed using over-the-air SET
messages; however, if these messages are not formatted correctly (i.e. out of
range parameter values are used), then the TrimTrac ProE will send a response
but the response will contain the existing configuration parameter values.
Different network operators may also handle queued up SMS messages
differently. For instance, if the TrimTrac ProE happens not to be in the QUERY
state when the server application sends a SMS message, this SMS message will be
held at the network operator’s Short Message Service Center (SMSC) for future
