output-spec is an integer below 32, whose bits tell the digitizer
which status lines to output.
●
Setting bit 0 (1) produces lines showing the current internal
clock offset, frequency error, and GPS fix type. For example:
2006 9 4 13:13:00 2 MicroSeconds Fast Freq error 0 e-9
Auto 3D [-4]
●
Setting bit 1 (2) produces lines showing the current GPS offset,
drift, PWM measure, and fix type. For example:
2006 9 4 13:13:00 o/s= 340 drift= 0 pwm= 8382 Fix= "3D"
●
Setting bit 2 (4) produces lines showing the GPS latitude and
longitude. For example:
2006 9 4 13:13:00 Lat= "51'21.6526N" Long="001'09.8148W"
●
Setting bit 3 (8) produces lines like
Boot Log : Power_cycles= 11 Watchdog_resets= 51
Last boot 2006 8 23 08:49:22 2006 8 23
08:50:40 Run 12Days 04:22:20
showing the number of times the digitizer has been reset, with
the time of the last reset and the current up-time.
●
Setting bit 4 (16) produces lines showing the current power
supply voltage and temperature. For example:
2006 9 4 13:13:00 External supply : 14.3V Temperature
29.75'C
The bits should be logically ORed (i.e. the decimal numbers added) to
produce multiple status lines. For example, the command
6 SETDSS (= 2 + 4)
will cause the digitizer to begin outputting status blocks containing
GPS timing and position information only:
2006 9 4 13:13:00 o/s= 340 drift= 0 pwm= 8382 Fix= "3D"
2006 9 4 13:13:00 Lat= "51'21.6526N" Long="001'09.8148W"
To use a DM24 with a DCM running a DSS server, you should issue
31 SETDSS
To return to normal operation, issue the command
