Serial
If you have a GX Series device with an I/O X-Card installed, you can execute
many of the serial commands “as is” in a terminal session connected to the
specific port for which the command is intended. However, you can explicitly
specify which port the command takes effect on by adding a port identifier to the
end of the full command.
*PPTIME
*PP2TIME
*PP3TIME
*PP4TIME
Query or set the GPS report time interval (in seconds).
AT*PP[Server number if other than server 1]TIME? to query
AT*PP[Server number if other than server 1]TIME=n to set
• n=0 – 65535 seconds
Note: Your cellular Mobile Network Operator may impose a minimum transmit time.
See also *PPMINTIME, *PPTSV, +CTA.
Note: A report time of less than 30 seconds may keep an RF link up continuously, tying up
an RF resource to transfer small amounts of data. Generally, the RF channel is released
and goes dormant in 10–20 seconds if no data is sent or received.
*PPTCPPOLL Query or set the port to listen on for TCP GPS report polling.
Note: The request to this port needs to come from the same IP address in *PPIP on
page 356 and uses the report type configured for server 1.
AT*PPTCPPOLL? to query
AT*PPTCPPOLL=n to set
• n=0—Disabled
• n=1–65535 (default 9494)
*PPTSV
*PP2TSV
*PP3TSV
*PP4TSV
Query or set the time interval in minutes that the device sends in reports when it is
stationary (Stationary vehicle timer).
AT*PP[Server number if other than server 1]TSV? to query
AT*PP[Server number if other than server 1]TSV=n to set
• n=0—Disabled
• n=1–255 minutes
For example, if *PPTIME=10, the device sends GPS reports at least once every 10 seconds
while it is moving; however, once it stops moving, it slows the reports down to this *PPTSV
value.
Note: In order for the PPTSV (Stationary Vehicle timer) to take effect, the PPTIME value
must be set to a value greater than 0 and less than the PPTSV value. The PPTSV timer
checks for vehicle movement at the PPTIME interval, so if PPTIME is disabled, then
PPTSV will also be disabled.
