Laser Measurement

AthleticFIELD allows laser measurement through BluetoothLE, TCP/IP, and Serial (Android only).

Supported Devices

Total Stations

  1. Mato MTS-602R
  2. GoWin TSK 202
  3. Sokkia SET5x
  4. South Station NTS-352R

Leica Handheld Lasers

NOTE: If measuring from the board, the laser and the prism must be at the same height and pointing straight at the laster.

We hope to implement Smart Horizontal Mode for the E7500i and X4 in the near future. This would allow you to use a tripod.

  1. Leica Disto D2
  2. Leica Disto E7500i
  3. Leica Disto X4

Connection Types

TCP/IP

This setup works with iOS and Android devices. Because serial doesn't work with iOS, this is the best option for a hardwire connection between total stations and iOS devices.

Purchase the following for each iOS device you intend to use.

  1. POE Ethernet adapter for iOS (Amazon Link). We like this one because it doesn't turn off when the iOS devices lock or go to sleep
  2. POE Switch (may or may not need this depending on your networking setup) (Amazon Link)
  3. Lantronix DB9 to POE connector (Amazon Link)
  4. Null Modem Adapter - needed because that particular DB9 to POE connector has its TX/RX pins reversed (Amazon Link)

This works by creating a mini-network between your total station and your device.

Serial (Android only)

To connect a total station to an Android device via serial, you need a micro-USB or USB-C OTG adapter. Plug the serial cable from the total station into the OTG adapter, then connect the OTG adapter to your Android device.

When setting up a serial device in AthleticFIELD, you need to know Baud, Stop BIts, Parity, Data Bits, and Flow Control. These are the most common settings:

  • Baud: 9600
  • Stop Bits: 1
  • Parity: None
  • Data Bits: 8
  • Flow Control: None

Most devices seem to work with the "Auto" option. If yours doesn't work, please contact ben@athletic.net so we can add your adapter to the list.

BluetoothLE

For Leica handheld lasers, we support connection via BluetoothLE.

To connect a device via BluetoothLE on the Laser Settings page:

  1. Enable Bluetooth and location on your device.
  2. Click Start Scan.
  3. Eventually, you should see your AirConsole or your Disto device.
  4. Click Stop Scan.
  5. Click "Connect" on the device. You'll see three dots. Once connection happens, the button will change to "Disconnect" and you'll see a green connection message.

NOTE: Previous versions of this documentation recommended purchasing an AirConsole to connect total stations to Android/iOS devices via BluetoothLE. This seemed to be too buggy, so we recommend using TCP/IP or Serial if at all possible.

Bluetooth Gotchas

  1. If your device moves over 20-25m away from the total station, you risk disconnects.
  2. If your device does disconnect, you should get a red warning asking you to reconnect.
  3. If a measurement fails, you can click a button to go back to the settings page and reconnect.

Laser Setup

  1. Open the app.
  2. Click on "Settings"
  3. Click on "Allow Laser Measurement"
  4. Click the back button at the top.
Connect to a Laser
  1. Click on Laser Settings.
  2. Set your options.
    1. Click "Active"
    2. Set your desireed Connection type
    3. Choose your Laser.
    4. Set Measure to Point to Point or Triangular.
    5. If using Bluetooth, choose the Receiver Type (AirConsole for total stations. Leica Disto otherwise).
  3. Click Save.
  4. Click "Test" in the bottom right.
  5. Click "Measure" in the bottom right. After a couple seconds, measurement data should appear.

Setup Throws Triangulation

Note: Triangular laser measurement only works for horizontal throws and for total stations at this time. It does not work with Leica Distos.

  1. From the Laser Settings page and after entering your laser settings, click "Setup Throws Triangulation"
  2. Select the appropriate circle radius.
  3. Click "Measure to Circle Center". After a couple seconds, you should see the measurement details.
  4. To ensure your measurement is correct, set your prism within the throwing area and measure with tape. Then, click "Test Measurement". Make sure the tape measurement and the app measurement correspond.

If you set the Circle Radius to Shot Put, this center circle measurement will work for all Shot Put events. If, for example, you change to a Discus event, the app will not let you take a laser measurement until you re-measure the center circle.

Measure a mark in an event

  1. Check athletes in, then prepare to enter a mark for an athlete.
  2. Click the wand icon in the "Mark" header.
  3. Within a couple seconds, the mark should appear.
