Settings#

The GU 192 V3 can be controlled though a command line Interface (CLI) using the USB connection. When connected, type help and press enter to see all available command. They are grouped into following groups:

  • clock

  • gnss

  • system

Serial Connection Tool#

Any tool that can connect to a serial COM port can be used to connect to the movement. This works on phones and computers on all major operating systems.

Examples:

Note: Since the connection is done via USB, Baudrate and similar settings don’t matter. The only relevant setting is the number/name of the port. The CLI accepts all types of line endings (\n, \r, \r\n)

Commands#

Clock#

Command

Sample Response

Note

clock set|get time <hh:mm:ss>

time 12:23:56

clock set|get timeOfDay <seconds>

timeOfDay 12345

in seconds since midnight

clock set|get date <dd:mm:yyyy>

clock set date 24:03:2026

clock set|get timeZone <zoneName>

timeZone Berlin

without continent prefix, default: Zurich

clock get swTrim

swTrim 1234

Unit: ticks/hour

clock get|set mode <12h|run>

mode 12h

Possible responses: 12h, run, searching, on time

SWTrim is the correction value in ticks per hour for the internal oscillator, derived from GNSS data.

Time zones are entered using names according to the IANA Timezone Database, but without the continent. For example, Europe/Zurich is entered as Zurich. Note the ASCII spelling without ü.

gnss sync now

Starting sync now

  • sync on|off: Turn GNSS reception on/off

  • syncTime: The time at which the GNSS module is turned on

  • syncInterval: How often the GNSS module is turned on

  • syncTimeout: How many hours the device can run without synchronization before it enters an error state

  • fixDuration: How long GNSS reception remains active

  • fixTimeout: How long the receiver should remain active when there is no reception

  • activeAntenna: Whether an active antenna is used or not

Settings Saved

system update

Connection stops

Device enters update mode

system reset

Connection stops

Restart, settings are retained

system factoryReset
