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
REG01=NMEA OUTPUT
Default value: 31
REG02=OPTIONS
Default value: 00
REG03=SMART LOGGER
Default value: 00
REG04=WAKE UP REGISTER
Default value: 00
REG05=LOW POWER MODE
Default value: 00
REG06=AUTO OFF/ AUTO EGA Function
Default value: 00
REG07=AUTO OFF countdown timer
Default value: 00
REG08= AUTO EGA countdown timer
Default value: 00
REG09= Vibration sensor threshold
Default value: 00
REG0A=Acceleration ALARM threshold
Default value: C0
REG0B= Startup message delay
Default value: 1e
REG0C= GSM WATCH DOG TIMER
Default value: 00
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.
