  1. TrimbleSPS730 and SPS930 Universal Total Stations How to Setup for Machine Control

  2. Agenda • Using Trimble SCS900 Site Controller Software to setup for Machine Control • Setup the SPS730 or SPS930 Total Station • Establish and orient the instrument • Set the search window • Set the Trimble MT900 target ID • Edit the machine list • Hand off to Trimble GCS900

  3. Setting up the Total Station • Use a heavy duty tripod • Trimble recommends p/n 571126275 • Needed to stabilize high speed Trimble MagDrive™ servo mechanism • Plant legs firmly in the ground, using a wide stance • Mount and level instrument

  4. Setting up the Total Station • Using either a Trimble TCU or TSC2, start SCS900 • TCU or TSC2 will auto connect when attached or cabled • TCU or TSC2 will not auto connect over Bluetooth or radio • From the Main Menu, tap System Setup (6)

  5. Setting up the Total Station • Next, tap Connect Instrument (1)

  6. Setting up the Total Station • Next, tap the method by which you want to connect. • Connect via Radio is used here (1)

  7. Setting up the Total Station • Next, set the radio channel and ID of the controller • This is the channel and ID stored in the instrument for later SPS use • Radio channel 1-30 are used for SPS, 31-60 for MC • Network ID is a value from 0-255

  8. Setting up the Total Station • Once you set the correct channel and ID, tap Next and the controller will connect to the instrument

  9. Setting up the Total Station • At the next screen, tap OK once you are satisfied with the leveling of the instrument • Make your selections on the next screen and adjust temperature if necessary, tap OK • PPM is automatically computed based on the values input for Pressure and Temperature

  10. Setting up the Total Station • When returned to the System Setup menu, select Setup Total Station Position (2)

  11. CP2 CP2 CP1 CP1 Setting up the Total Station • Tap (2) to setup over a known point • Tap (1) for a free station setup • You must be able to see 2 or more known points for this setup BAD SETUP! Resection angle <30 degrees GOOD SETUP! Resection angle 30 – 150 degrees

  12. Good vs Bad Setup • First setup, instrument and control points are in a line • Bad geometry for a re-section • No intersection angle could result in poor computed position of the instrument • Second setup, instrument and control points form a decent triangle • Good intersection will result in a good computed position of the instrument • Avoid free station setups where intersection angles are very narrow (<30 degrees) or very wide (>150 degrees)

  13. Setting up the Total Station • Follow prompts in measuring to control points to position and orient instrument • Setting up over a known point requires measuring to at least one other known point • Setting up over an arbitrary location requires measuring to at least two other known points • The more points measured, the better

  14. Setting up the Total Station • Once you’ve measured to either one (known point setup) or two (arbitrary location setup) control points, you are brought to this screen • Choose Complete Instrument Setup (2)

  15. Setting up the Total Station • You are now given two options • We will choose Setup for use with machine control (2)

  16. Set the Search Window • Define your search window • Tap the Set button after aiming to each location • Either top left/bottom right, or top right/bottom left • You will see green circles once the corners of the search window have been recorded • Tap Next once both corners have been set

  17. Search • Two searches instrument performs • Quick search • Small search window based on last tracked position of target and a horizontal / vertical window defined by angle values in SCS900 • Full search (search window defined in SCS900) • Should be looked at as the extents of your working area • If quick search does not reacquire lock, instrument goes into full search

  18. Set the MT900 target ID • The next screen allows you to set the target ID of the Trimble MT900 Machine Target • If aimed in the vicinity of the target, tap the Check ID button, and SCS900 will retrieve the target ID the MT900 is currently set to • If you know which ID the MT900 is set to, select it from the drop down and tap Next • If you wish to change the target ID, select the number from the drop down, and tap Set Target ID

  19. Changing the MT900 Target ID • Only necessary for SPS use with the MT900 • If you wish to change/set the target ID of the MT900, you must be connected to the MT900 via the MT900 Junction Box • Can also be changed later via the Trimble CB430 Control Box and GCS900 • IDs 9-16 are used strictly by the MT900 • IDs 1-8 can be used by either the MT900 or the active target ID box for SPS use • 1-8 should be used for MC only as last resort

  20. Edit the Machine List • Once you finish setting the MT900, you are brought to this screen • If the machine list was previously loaded to the instrument, tap Get Machine List and it will be retrieved by SCS900 and will populate this screen • If you are creating a new list, tap Add…

  21. Create an Entry in the Machine List • Radio channels 31-60 are reserved for MC use, 1-30 for SPS use • Give the machine a specific name and assign a radio channel from the drop down list, and tap OK • Load up to 5 separate machine names / radio channels

  22. Edit the Machine List • Once you’ve loaded all the machines that you need, tap Save • Giving the machine a unique name that the operator can remember will help in cases where multiple machines are used on site • Name the instrument (not shown), tap Next

  23. Hand off to GCS900 • Point the instrument in the area work will start and tap OK • The instrument radio is configured for MC use • Now disconnect from the instrument at the next screen • If connected via radio or Bluetooth, the connection will be terminated for you

  24. Hand off to GCS900 • The Face 2 display on the instrument shows the instrument scanning one SPS channel, and then the machine control channels loaded earlier from the machine list • Station setup information is written to a memory location in the instrument • GCS900 then calls that information from the instrument

  25. Summary • Setting up with SCS900 takes the normal time to setup and orient an instrument, plus a very short amount of time to go through the Machine Control wizard • MT900 • Target ID 9-16 reserved for MC only, 1-16 available (use 1-8 as last resort only as these are the only IDs available for SPS use) • Radio • Machine use, channels 31-60 • SPS use, channels 1-30
