Instruments

Operating FieldWorks with different Instruments, total stations and GPS

1. Connect FieldWorks and instrument using the correct cable. Contact your instrument dealer or XYZworks if you do not have a cable.

2. Start the FieldWorks software.

3. Configure FieldWorks to work with the instrument, if this has not been done. Enter the Options function and select the appropriate instrument. With some instruments you may need to set the baud rate, see below for settings and refer to the instruments operating manual. If the default baud rates will not work with your instrument, see the Baud rate function to change the settings. You can use faster baud rates if you like, as long as Fieldworks is set to match the instrument settings.

4. Use the Collect function to collect data, or the Stakeout functions to stake points.

5. Point the instrument at the prism. You do not need to make a distance measurement on the instrument first, but you can if you want to. Press Measure or Track on FieldWorks. This triggers a measurement and data will transfer and display when measurement is complete. If no data is received within 60 seconds, the function will time out and display a message box: cannot read COM. Re-aim the instrument or check your cables and try again. The Track function will continue to trigger measurements until you hit the Measure, Next Pt or Sideshot function keys.

At this point instructions will vary for different brands of instrument. See the appropriate section below for your instrument: Pentax, Topcon, Geodimeter , Laser Atlanta, Nikon, Sokkia/Lietz, Leica/Wild, NMEA 0183 GPS, Level or Topcon APL1A/GTS-800,Bluetooth/GTS-800.

Model: PENTAX DA-020 series, PCS 200, 300 and 500 series

You should set the instrument to display HA, ZA, SD so that you can confirm that the data transferred correctly. The instrument does not need to be in track (continuous) mode to use the FieldWorks Track function, but the screen display of Towards/Away, Left/Right, Cut/Fill will update slightly faster if you set the instrument to either track or CM mode.

Communication settings: 1200 baud, no parity, 8 data bits, 2 stop bit.

The DA-020 always uses these settings and cannot be changed. The PCS 200, 300, and 500 series default to these settings, but may need to be reset if someone has changed them from this setting. See the Pentax owners manual for instructions on settings.

Model: TOPCON GTS series

You should set the instrument to display HA, ZA, SD so that you can confirm that the data transferred correctly.

Communication settings: 1200 baud, even parity, 7 data bits, 1 stop bit, delimit CR/LF, REC-A, Protocol ON.

See the Topcon owners manual for instructions on setting the instrument.

Model: GEODIMETER 400, 500, 600, 4000 series, TRIMBLE 5600

Communication settings: 9600 baud, no parity, 8 data bits, 1 stop bit, F79 – EOT character 4. Robotics: Slave: No, Req: No, Table 0.

See the Geodimeter owners manual for instructions on setting the instrument. If you select Servo then the Turn button may be used to automatically turn to each new stakeout point after entering the point number and pressing Tab, or after pressing Next Pt.. For robotic mode from the pole, see below.

Model: LASER ATLANTA – ADVANTAGE series

There are 3 options available for these handheld instruments, selected in the options routine:

a) Single – press the Measure button on FieldWorks, then aim and hit the trigger. (repeat for each shot)

c) Multiple – press the Measure button on FieldWorks, which will go into an infinite wait for data mode and recording every shot taken by the trigger on the instrument. The drawback to this mode is that keeping the serial port open and looking for data will drain the battery of the palm-size pc quickly. If you wait more than 60 seconds between shots, the unit times out and you need to hit the measure button again when ready. To get out of the measure routine, wait 60 seconds for it to time out.

c) Triggered – press the Measure button on FieldWorks and it triggers the shot immediately (probably need tripod mount to be useful) like we do with most surveying instruments.

Communication settings: 4800 baud, Serial Format: PRO XL

Model: NIKON D50, C100, DTM, A, and Topgun series

Communication settings: 4800 baud, no parity, 8 data bits, 2 stop bits.

Model: SOKKIA/LIETZ SET series

Communication settings: 1200 baud, no parity, 8 data bits, 1 stop bit.

Model: ZEISS R50, Trimble 3300 series

Communication settings: 9600 baud, no parity, 8 data bits, 1 stop bit.
To configure the instrument, hold Shift-Menu, select 5-Setting Interface, hit Yes, and set Recording V24/1, Format REC500, Parity None, Baudrate 9600.

Model: LEICA (all including Servo/Robotic) and WILD T/TC1010, T/TC1610, T2002

Communication settings: 9600 baud, no parity, 8 data bits, 1 stop bit, , CR/LF.

If you select Robotic then the Turn button may be used to automatically turn to each new stakeout point after entering the point number and pressing Tab, or after pressing Next Pt.. For robotic mode from the pole, see that driver below.

Model: WILD T1000, T1600, T2000

Communication settings: 2400 baud, even parity, 7 data bits, 2 stop bits

If you have a T1000, it must be vers. 1.4 or newer and must be set to run in T2000 mode by pressing SET, 5, 7, 4, RUN, then press REP until T2000 is displayed, then press RUN.

Model: NMEA 0183 GPS

Communication settings: 4800 baud, no parity, 8 data bits, 1 stop bit.

This driver works with any GPS that outputs in NMEA 0183 format (the GGA sentence of latitude and longitude, and optionally the GST sentence for coordinate quality.) This includes most brands of GPS made, including everything from the small consumer units like Garmin and Magellan, up to the more accurate units like Trimble, Topcon/Javad, Ashtech, CMT, and Allen Osborne. Make sure the GPS is set to the WGS 84 datum, since the latitude and longitude downloaded are converted in Fieldworks to a zone in the WGS 84 datum (in Meters,) and position errors can occur if different datums are used. The ‘Save field data’ option is turned off when using this driver since there are only coordinates.  See the File – Zone function to set a state plane zone for coordinates.  See the Tools- Channel function to change radio channels.

When you enter the Collect or Stakeout functions, or press New Setup, the following dialog box will appear for setup options (localization.) Most options apply only at the rover, not the base. The base will have grid coordinates and ellipsoid height in meters (or feet if the Convert to feet box is checked.) Ground coordinates are a simple way to integrate total station measurements with GPS. A ground coordinate system should normally only be used on projects less than 2 miles across to limit the error to 0.05′ (due to the difference between a plane and the ellipsoid.) The other way is to use grid coordinates by not checking the Grid to ground box. Whether using grid or ground, if you have at least one point at the rover with known coordinates and quality you translate to, you get higher accuracy. Before doing this, make sure you have good coordinate quality and a good distance between the translate and rotate points since the accuracy of the job is affected by those points. Remember that it takes several minutes for the RTK rover to get a fixed solution, indicated by the HQ dropping from around 3′ to 0.03′ after hitting Measure on the Collect or Stakeout screen.

Use the Convert grid to ground box to turn on or off the application of the grid factor.Use the Convert to Feet to convert GPS coordinates to US Survey feet. Use the Convert to Intl’ Feet to convert GPS coordinates to International feet.
Use the Geoid box to adjust elevations using Geoid99 (or newer) see Geoid notes.
Press the Trans. point button when you are connected to your GPS and positioned over a point near the centroid of your project. The coordinates of that point appear along with the computed scale factor and grid factor at that point. You can use the computed grid factor, or enter your own grid factor, or ignore it if you are not converting to ground.
To translate points, enter a Trans to point number. If the point does not exist, you will be prompted to enter the coordinates. To do no translation, enter a point# of 0.
To rotate points into your own system, move to a second point with known coordinates or a desired bearing from the first point, and press the Rotate button. The prompt (Position over rotate point) Enter Rotate to bearing? appears. Press Yes to enter a bearing or No to enter a Rotate point#.
If entering a bearing:
Rotate to bearing or pt#,pt#:
The grid bearing between the 2 points is displayed. The amount of rotation applied is displayed. Enter the desired bearing for that line, or 2 point numbers, and press OK. If you cancel this dialog you get 0 rotation.
Or if not entering a bearing:
Rotate to pt#:
Enter the point number in your coordinate file of the Rotate point. The program computes the rotation and scale to adjust the GPS data to fit the Translate and Rotate points. If you cancel this dialog you get 0 rotation.
Computed scale = 0.99965
Use instead of 0.999543?
The program displays the computed scale and the original scale computed at the translate point. Press Yes to use the new scale or No to use the original scale. The amount of rotation applied is displayed in the lower right corner, and printed in your coordinate quality (.CQ) file. You may want to Rotate your job coordinates into Grid north by collecting 2 grid points and using the Coordinates-Rotate function to make your basis of bearings grid north instead of using this function to Rotate into a different basis of bearings. This is because grid north (no rotation) is more easily repeatable by yourself and others in the future.

The Skyview button produces a graphic plot of all the satellites in view and highlights the currently locked satellites. It continues to update until you hit the Menu button. If you are using the NMEA GPS driver, you need to set your GPS to output the GSA and GSV sentences if you want a Skyview. Garmin GPS always send this when you have NMEA output chosen.
The Tolerance field is used so the program warns with a special beep when HQ exceeds the tolerance during Collect or Stakeout. To avoid those warnings, don’t enter a tolerance or set it high. With NMEA, the HQ number is the Horizontal Dilution of Precision, and the accuracy is nearly a constant # times the HDOP, for a Garmin without WAAS, accuracy = HDOP x 5. For all GPS except NMEA, the HQ number is actual accuracy, and the coordinate quality will be displayed in fields labeled HQ: for the horiz. quality, and VQ: for the vertical quality. A report of the point#, latitude, longitude, ellipsoid height (corrected only for HI) and 3-D quality of each point collected will be saved in a file with the job name and a .CQ extension.
All the GPS settings on this screen are saved with the job and recalled each time you come back to simplify setting up again, you just hit OK. You should normally not change the setup after collecting some points, since then you may create a slightly different coordinate system that may not match your previous one. The elevation difference between the collected point and the stored translate to point will be displayed and you have the option to adjust your GPS elevations by this amount, press Yes or No.

Geoid
If you don’t understand what a geoid model is, you should not check this box. This is a way for advanced users to get more accurate elevations. When this box is checked, the program uses a Geoid99 (or newer) .BIN data file that you download from NGS at http://www.ngs.noaa.gov/GEOID/GEOID99/dnldgeo99pc1.html. After downloading, you should extract a portion of the Geoid file using the XNTG program from the NGS. . If you don’t have fast internet access, contact XYZworks to get the data on a CD. Choose only an area which covers the latitude and longitude you work in, since the original files from NGS cover many states and consume 4.7MB of memory and will slow down the program. This extracted file is then renamed to geoid.bin and copied to the \Mobile Device\My Documents folder. This way you could have several geoid files on your desktop PC and download to the data collector only the file you need for the portion of the state you are in. If you don’t do this before checking the Geoid box, or if you move outside the portion of the geoid you have loaded, you will get an error message. With Leica GPS, it is better to load the geoid into the receiver instead of the data collector and not check this box.

When you go to the Collect screen, there will be 2 new buttons when using a GPS driver. The AutoInv button is used to display the bearing and distance from any stored point to the current position, updating rapidly as you move. Useful to find corners by simply watching the bearing and distance update as you walk until you get near what the plat bearing and distance is. After you find a point and save it by hitting Sideshot, that point becomes the new From: point for the next AutoInverse bearing. Or hit AutoInv again and enter a different point.

The Adj.Brg button is used in Collect when displaying the AutoInverse bearing, to adjust (rotate) the true bearings displayed to match an old plat bearing. The adjusted bearing is displayed below the true bearing. The computed rotation angle will be added/subtracted from all future AutoInverse bearings until you do a New Setup or choose Adj.Brg again. This does not affect coordinates that are stored, it is only for display.

Model: Leica GPS

Communication settings: 9600 baud, no parity, 8 data bits, 1 stop bit. Use the Leica controller, hit Configure, Interfaces, Remote interface, Port 2, RS232 Device. You do not need to set it to send NMEA with this driver.

See Operating with GPS above for a description of other options. You can disconnect the Leica controller and use only Fieldworks on the Rover if desired. You also have the option to get/send ASCII coordinate files to the PC Card storage on the GPS by using the File menu – To RS232 and From RS232 functions. The battery % charge for the A and B battery are displayed on the New Setup screen. You can also turn off the Rover from that screen. Remember to enter the antenna height either into the Leica controller, or as the H.I. in Fieldworks, but not both places.

Model: Digitrace depthfinder and NMEA depthfinder

Communication settings: 9600 baud, no parity, 8 data bits, 1 stop bit.

This instrument is only a choice if you check the 2 Inst. Box on the options screen. It will automatically take a reading immediately after a reading from the main instrument. The depthfinder must be hooked to COM1 and the other instrument hooked to an added port, usually COM5. See Tools-Baud rate to set the COM port for the other instrument. The depth will be subtracted from the elevation computed from the main instrument. The depth reading is appended to the description of the point.

Model: File Capture

Communication settings: 9600 baud, no parity, 8 data bits, 1 stop bit.

This is a special driver used to capture whatever data comes into the COM port and store it in a file with the job name and an extension of .CAP. This can be used for troubleshooting or to log static data to a file (if you have your GPS configured to output the proper data.) Go to the Collect screen and hit Measure to start capturing data. The number of lines of data will appear in the #S field. Tap on the blank area of the screen to stop the file capture.

Model: Bluetooth instruments setup

Make sure your instrument is set to Bluetooth, for the Topcon GTS235 you hit Menu, F4, F4, F2: Parameters, F4, F4, F1:Select COM, F1:Bluetooth.

The process will vary slightly depending upon what handheld you are using, here are the keys to get it setup:
HP iPAQ: Hit the Bluetooth icon in the lower right corner, and pick enable Bluetooth. Then hit it again and pick Bluetooth manager, New, Connect, Explore a Bluetooth device, Next, Next. Then your instrument should appear, choose it, for Service selection pick COM1, Next, Finish. To find out what COM port number to use, hit the Bluetooth icon in the lower right corner, and pick Bluetooth settings, hit right arrow until you see the Serial port tab, hit that tab, check the box Enable service, then read the Outbound COM port number, on my iPAQ 2215 this is port 8. Enter that number into Fieldworks BAUD function and the program will use the Bluetooth connection instead of the cable. You can enter a fast baud rate, try 38400 into the baud rate.
If you have a PIN# in the instrument, either enter it when prompted, or use bluetooth manager, pick paired devices, hit the lookup icon, choose the device, then enter the PIN# which is usually 1111 for Topcons.

Fieldbook or Panasonic: with Socket Bluetooth card, hit Bluetooth icon in taskbar, Advanced Features- Bluetooth Devices, then Tools-Device Discovery, Next, Next, Check the box for adapter, Next, Finish. Device, Bond, Next, enter 1234 or whatever your devices PIN# is (if needed), Reply, Finish. Tools, My Favorites,Com Port tab, Check use the favorite selected, OK. Then enter 9 for COM port in Fieldworks Baud function.

Fieldbook XL: hit Bluetooth icon in taskbar, Bluetooth Connection manager, Generic device search, Next, select the device, Next, select Serial 01, Next, check add this to my favorites, connect. Then to use each time you power up, hit Connection Manager, My Bluetooth favorites and double tap the icon for the instrument before you Measure. Or keep My Bluetooth favorites on the taskbar and hit it there. Enter 6 for COM port in Fieldworks Baud function.

File – View

This function is used to view text files created by Fieldworks such as a coordinate quality .CQ, cutsheet .CUT, or printout.txt file. The only prompt is to choose the file name. It defaults to show CQ files, to show other types of files, choose the type from the drop down list.

File – Zone

This function is used to choose a state plane zone for GPS coordinates: UTM, NAD83 Lambert or Transverse Mercator. If you have not chosen a zone, it defaults to UTM since that works worldwide. The Lambert zones are listed first, then the Transverse Mercator. Pick a Zone from the drop down list, and hit OK. The zone you have chosen is saved and used with any jobs you open. UTM and NAD83 State Plane Coordinates are in meters by definition. To perform an automatic conversion to/from US Feet (*3.28033333) or to/from International Feet ( /0.3048) check the appropriate radio button. These don’t convert the elevation, just N and E. It is recommended that if you apply any conversion to the metric units you also translate the numbers (such as drop the millions digits using Coordinates-Rotate) so people don’t mistake they are SPC.

To transform stored grid points to Latitude and Longitude, press the To Lat button. Enter a file name for data to be stored in, defaults to a .lat extension. Then enter the first and last points to be transformed, and press OK. The latitude and longitude of the points is stored in ASCII format and also displayed.

To transform an ASCII file with the format: Point# Latitude Longitude Elevation Description into grid coordinates, press the From Lat button, and enter the file name  to read the data from. The computed grid points are stored in the current job.

To enter a Latitude, Longitude and Elevation and transform into grid coordinates, press the EnterLat button. The program asks for a Point# and stores the point in the current job.

TOOLS-CHANNEL

Use this function to change the channel on PacCrest radios used for RTK and Robots, including the internal radio in Ashtech and Topcon HiPer GPS. This is useful if you are getting radio interference on a busy frequency. For brands other than Ashtech and Topcon, you need to be connected directly to the radio. For Topcon, the radio must be on port C or internal. For Ashtech, the program asks for the Port (B-D) where the radio is connected, port D is used for an internal radio.

There are some tricks sometimes needed when changing channels on Ashtech and Topcon rovers if the receiver is busy trying to process the incoming corrections it may not respond to the channel commands. The tricks are to disconnect the radio antenna (at the rover, not the base!) to stop it from processing that extra data, and/or turn off the base radio so it is not sending the corrections. (if you are within a hundred meters of the base it can still receive corrections even with no antenna – if the receive light is flashing, this could interfere with channel changing.) After changing the channel on Ashtech or Topcon radios, you need to do a new Set Base or Set Rover command. The program displays:

Channel (0-15): The current channel is displayed. Enter the desired channel and press OK. Make sure to finish this function (don’t terminate the active program or disconnect the radio), since the radio is put into a special ‘Packet Mode’ which doesn’t get reset to normal ‘Transparent Mode’ until you finish this function. With Ashtech and Topcon HiPer, it also sets up a ‘Daisy Chain’ so commands that are sent to the GPS get directed to the radio, so this is another reason to be sure to finish this command. Remember to change the channel at both the base and rover to the same channel.
