Input Module
Sends an input module firmware version request at about 1Hz until a response is received.
Thereafter it sends a data request on receipt of every GPS sample.
Laptime Telemetry
Sends a telemetry messag when a finish of start/finish gate is crossed. If „SplitOutput‟ is enabled it
will send a telemetry message when a split gate is crossed.
Laptime Pulse
Sets the lap time pulse for 0.25 seconds when a finish or start/finish gate is crossed. If „SplitOutput‟
is enabled, it will set the lap time pulse for 0.25 seconds when a split gate is crossed.
Drift Telemetry
If in Drift Sectors mode and sector 1 start gate is crossed, the unit will send a telemetry message .
If in Drift Sectors mode and a sector end gate is crossed ;
If „TELEM.FORMAT2‟ is not enabled the unit will send telemetry message 1
If „TELEM.FORMAT2‟ is not enabled the unit will send telemetry message 7 and aslo write the
information into a scores.log file.
If in Drift Practice mode (sectors not selected) the unit will output practice drift information at 10Hz
shown below :
$DBOX,sss.s,±g.gg,±l.ll,±ddd.d,pp.pp
Yaw Diagnostics
Will output temperature, yaw rate and yaw calibration (offset and gain) as shown below.

01828,01764,1766.10, 6.82545
Where:
temperature is corrected ADC count 2 + Calibration MinTemperature
yaw rate is corrected ADC count 3
yaw cal offset and gain are the current gain and offset being applied to calculate the yaw.
