The following information describes the various options available for the Geodimeter 600 and Trimble 5600 total stations. It's important to note that firmware 696-03.xx or later is required. To check firmware version, select Menu 5, 4, 1 on the instrument.
Comms
Geodimeter/Trimble default communication settings in SurvCE are 9600,8,None,1. To check these settings on the instrument, do the following:
- Select MNU, ENT, 4 (Data com), 1 (Select device), 2 (Serial)
- At prompt “Serial ON?”, select ENT
- Verify COM=1.8.0.9600 followed by ENT
The software allows you to run the instrument in several modes, depending on the capabilities of the instrument. Selecting a model that says DR informs the software that the instrument is a reflectorless (Direct Reflex) model, and the reflectorless EDM mode will be made available.
Settings/Search (Station)
If the instrument is not robotic or you want to operate it as a standard total station, the Station mode should be used.


- EDM Mode: Allows you to specify the EDM measurement setting as one of the following types:
Standard: Standard EDM mode.
Fast: Fast Standard EDM mode.
Reflectorless: Reflectorless EDM mode (DR Models).
- Turn to point in stakeout: Turns the instrument to the horizontal angle as computed to the stakeout location specified.
- Turn to vert. point in stakeout: Turns the instrument to the vertical angle as computed to the stakeout location specified. This option is not typically used unless a true elevation is known for the stakeout location specified.
Settings/Search/Remote (Direct Robotic)
This mode works exactly as the GeoRadio mode except a cable must be used in lieu of the radio. For this mode,the instrument must be robotic and be operating in the Remote mode with the faceplate removed.

- EDM Mode: This selection allows the user to specify the EDM measurement setting as one of the following types:
Standard: Standard EDM mode.
Fast: Fast Standard EDM mode.
Reflectorless: Reflectorless EDM mode (DR Models).
- Guide Lights: This sets the track lights to one of the following options:
Off: Turns off the track lights.
Low: Turns on the track lights on low power.
High: Turns of the track lights on high power.
- Allow Weak Signal: This will allow the instrument to return a distance when the signal is weak.
- Always Initialize Compensator: This will reset the compensator every time the instrument is restarted.

- Search on Read: This setting will force the instrument to perform a search before initiating a reading if the instrument is not locked on the prism.
- Diode Backsight: This setting allows the user to specify if the backsight has an active diode prism or not.
- Horizontal/Vertical Range: These input boxes allow the user to specify the range to search for the prism when a search function is initialized.
- Minimum/Maximum Distance: Determines the range by distance that the instrument will search for or track a prism.

- Standard Deviation: Defines the allowable standard deviation of the instrument readings.
- Search When Lost Lock: This setting will force the instrument to begin searching for a prism as soon as lock is lost.
- Turn Off Instrument: Turns off the instrument.
- Initialize Instrument: Turns on the instrument and initializes the instrument.
Settings/Search/Remote (GeoRadio)
This mode works exactly the same as the Direct Robotic mode, except a GeoRadio must be used in lieu of the cable. The instrument must also be robotic and be operating in the Remote mode with the faceplate removed. The only additional settings are for the GeoRadio itself.

- Initialize GeoRadio: Turns on the instrument and initializes the instrument.
- Channel: Specifices the channel of the GeoRadio.
- Station Address: Specifies the station address of the GeoRadio.
- Remote Address: Specifies the remote address of the instrument's radio.
Putting the 600 in the “Remote Mode”
- Power the 600 on.
- Answer the initial questions.
- If you have not selected the Radio Channels and Address, do the following:
- Press <Menu>.
- <1> for Set.
- <5> for Radio.
- Select Channel (1-8).
- Select Station Address (1-99).
- Select Radio Address (1-99).
- Press <RPU>.
- Press <3> for Remote.
- Press <1> for OK.
- Press <No> for Sector.
- Press <No> for Measure Ref Object.
- Press any key when prompted. You do not have to remove the keyboard as prompted unless you are using the Direct Robotic option instead of GeoRadio. SurvCE will control the total station.
