Using AUX2 input to count digital pulses:
You can select the feature using the configuration menu program.
Select the ‘View/Setup/Select Voice/ ADC Configuration’ option.
Select AUX2 input function to ‘Pulse counter’. The counter can count from 1 to 65535 Max. After 65535 the
counter will reset back to zero and continue counting.
When enabled the pulse counter value is automatic added to the end off the location message in Hex format.
The hex format is from 0000 to FFFF (65535 decimal).
The ‘Pulse counter Prescale’ can be used where more then 1 pulse is generated per KM. As example you
have a vehicle where 10 pulses are generated every 1 KM. In this case you can configure the prescale
counter to 10. Once the ‘Prescale’ counter has counter 10 pulses the ‘Pulse counter’ will increase with 1.
The maximum value for the ‘Prescale’ counter is 65535.
Example (counter value is 043F (hex)):
05*850,000,L001,A,2459.3640,N,12125.2958,E,000.0,224.8,00.8,07:47:26 09-09-05,9.00,D3,0,C4,1,043F
The AUX2 option must be selected using the configuration menu program. It cannot be enabled or disabled
any other way.
Care must be taken when there is noise on AUX2 input. The counter will increase every time a high to low
pulse is detected.
