To achieve more detailed programming the TCS-GPS has some registers in which each bit has a meaning and that can change dramatically the functions of the unit.
Before being able to use them you should be able to read an hexadecimal number out of a byte, if you need some hints please see a quick example at the bottom of this page.


Here are the details of the various registers that can be programmed with the command #REGrr,vv where rr is the register to be prorammed and vv if the hexadecimal value.

REG00=Service messages
Default value: 00
  • bit 0: Enable SVC MSG: SECXX FULL (#MTX31)
  • bit 1: Enable SVC MSG: AUTO OFF! (#MTX31)
  • bit 2: Enable SVC MSG: EGA ON! (#MTX30)
  • bit 3: not used
  • bit 4: not used
  • bit 5: Enable SVC MSG: GSM READY (#MTX31)
  • bit 6: Enable SVC MSG: GSM WDOG ON! (#MTX31)
  • bit 7: Enable SVC MSG: RCVRY GSI TABLE (#MTX31)


  • REG01=NMEA OUTPUT
    Default value: 31
  • bit 0: Enable GGA sentence (not changeable)
  • bit 1: Enable GLL sentence
  • bit 2: Enable GSA sentence
  • bit 3: Enable GSV sentence
  • bit 4: Enable RMC sentence
  • bit 5: Enable VTG sentence (not changeable)
  • bit 6: not used
  • bit 7: Send NMEA sentence on COM3


  • REG02=OPTIONS
    Default value: 00
  • bit 0: Enable DEBUG SMS on TEL01
  • bit 1: Switch data call to GPS engine
  • bit 2: not used
  • bit 3: not used
  • bit 4: Mark position on input 1 active
  • bit 5: Enable delayed power up
  • bit 6: not used
  • bit 7: not used


  • REG03=SMART LOGGER
    Default value: 00
  • bit 0: Enable 'smart logger'
  • bit 1..2: to mark a point, direction must change degrees: 00=5, 01=10, 10=15, 11=20
  • bit 3: no 'smart logger' below 20 km/h
  • bit 4..7: to mark a point, speed must change: 0000=10%, 0001=20%, ...1001=100%


  • REG04=WAKE UP REGISTER
    Default value: 00
  • bit 0: not used
  • bit 1: Wake-up on serial input COM3
  • bit 2: Wake-up on power presence
  • bit 3: Wake-up on Vibration Sensor
  • bit 4: Wake-up on Input 1
  • bit 5: Wake up on GSM modem RING
  • bit 6: Wake UP on RTC interrupt (#CLA)
  • bit 7: not used


  • REG05=LOW POWER MODE
    Default value: 00
  • bit 0: Modem OFF after STP command
  • bit 1: GPS OFF after STP command
  • bit 2: not used
  • bit 3: not used
  • bit 4: Modem OFF after AUTO OFF
  • bit 5: GPS OFF after AUTO OFF
  • bit 6: not used
  • bit 7: not used


  • REG06=AUTO OFF/ AUTO EGA Function
    Default value: 00
  • bit 0: Enable AUTO OFF function countdown
  • bit 1: Enable AUTO EGA function countdown
  • bit 2: reset countdown on serial input activity
  • bit 3: reset countdown on Power Presence
  • bit 4: reset countdown on Vibration sensor
  • bit 5: reset countdown on IN1
  • bit 6: reset countdown on Modem Ring
  • bit 7: reset countdown on Speed>0


  • REG07=AUTO OFF countdown timer
    Default value: 00
  • bit 0...7= from 0 to FF (255) minutes


  • REG08= AUTO EGA countdown timer
    Default value: 00
  • bit 0...7= from 0 to FF (255) minutes


  • REG09= Vibration sensor threshold
    Default value: 00
  • bit 0...7= from 0 to FF (0-255 decimal) 0=very sensitive


  • REG0A=Acceleration ALARM threshold
    Default value: C0
  • bit 0...7= from 0 to FF. Values below 40 could be too sensitive


  • REG0B= Startup message delay
    Default value: 1e
  • bit 0...7=from 0 to FF minutes.


  • REG0C= GSM WATCH DOG TIMER
    Default value: 00
  • bit 0..7= From 0 to 18 (0-24 decimal)






  • Hexadecimal number primer:
    Assuming bit 0 is on the right and bit 7 is on the left side:
    00000001 is 01
    00000010 is 02
    00000011 is 03
    00000100 is 04
    00001001 is 09
    00001010 is 0A
    00001011 is 0B
    00001100 is 0C
    00001101 is 0D
    00001110 is 0E
    00001111 is 0F
    The same thing happens for the upper nibble, so:
    00010000 is 10
    11100010 is E2
    and so on.
