Install SIM Card into Telemetry Module

Purchasing a SIM Card

Which SIM card to get?

This is largely determined by the coverage map of the race track you'll be at. Use the coverage map checker for the respective carriers.


Purchase a "Pay By the Day" SIM card from your local T-Mobile dealer. We recommend picking a plan with the 2G/3G unlimited data, which is currently $3 USD/day. The plan is only charged when data is actually used during a 24 hour period. Visit T-Mobile for more details on prepaid plans.

Installing SIM card

  • Open telemetry enclosure

Unscrew the end plate on the antenna side of the telemetry module and slide the board from the case.

Unlatch SIM card holder

Unlatch the card holder by gently sliding the cover in the 'open' direction and swing the cover open.

Insert SIM card

Insert the SIM card, taking note of the beveled edge. The SIM card can only be inserted in one direction.

Latch simcard holder in place

Swing the cover closed and slide towards the 'lock' position. take care that the cover is locked on both sides of the holder and it is flush with the board.

Re-assemble case

Slide board back into enclosure. Ensure LEDs are aligned with end plate and reattach end plate with screws.

  • You may need to gently press the LEDs down flush against the board in order for them to line up with the holes in the opposite end plate.

Connect components

Connecting Antenna

  • Connect antenna to RF port

Thread antenna onto RF port of telemetry module, position antenna in vertical position and then torque the nut, locking the antenna into position.

  • Don't overtorque! You only need a moderate amount of force on the nut.

Telemetry LEDs

Power LED

  • Rightmost LED

The telemetry module is powered by RaceCapture/Pro via the RJ11 tethered cable. It should glow constantly when powered up.

Network status LED

  • Middle LED

The Network status LED will flash indicating the cellular network status.

  • Searching: Flashes once per second when searching for the network
  • Registered on network: Flashes slowly (once every 3 seconds) when registered to the cellular network.

Transmit / Receive LEDs

The Transmit/Receive (TX/RX) LEDs indicate communication activity on the network, useful for diagnostics.

  • Top Left LED

This LED will flash when RaceCapture/Pro is transmitting to the network.

  • Bottom Left LED

This LED will flash when RaceCapture/Pro receives data from the network.

When RaceCapture/Pro is streaming to the network you will observe a constant blinking of the Transmit LED.

Install RaceAnalyzer

Follow the software installations instructions here: http://www.autosportlabs.net/RaceCapturePro_SoftwareOperation

Configure RaceCapture/Pro

For general RaceCapture/Pro installation and configuration be sure to review the Installation and Software guides.

Read Configuration

Before configuring any parameters read the configuration from RaceCapture/Pro

Set channel sample rates

Note, with the real-time telemetry sample rates are automatically limited to 10Hz. Logging to local SD card will be at the normal sample rates defined in the configuration.

Available bandwidth

The total available data rate is a function of number of channels combined with sample rate and is also affected by cellular network conditions. We will have an expanded guide and tool set to help identify optimal sample rates.

Set device id

Add your device id that you wrote down when adding your device to race-capture.com to the Telemetry Device Id field under the Logging/Telemetry section: Devicesetup.png

Write configuration

  • Click the 'Write' button in RaceAnalyzer
  • Power cycle RCP (turn off then on again)


RaceCapture/Pro with GPS & telemetry needs more power than a regular USB port can supply. You'll either need to connect it to your car's power directly, via a cigarette power adapter with wires or a powered usb hub similar to these:

We have not tested the above units; we offer them as suggestions of possible USB hubs with enhanced power capabilities.

Press the black switch on the front of your RaceCapture/Pro device to start logging. You will observe the Transmit LED blinking rapidly once the Cellular module is registered to the cellular network and after the link has been initialized, which ranges from a few seconds and up to 1 minute.

Got to race-capture.com/home, you should see a new event labeled 'Ad-hoc event ...', click on it, then click on your device on the next page.

If you cannot see data flowing to www.race-capture.com check the following:

  • Your RaceCapture/Pro logging rates are set to the suggested sample rates
  • You are powering RaceCapture/Pro using a 12v power supply through the terminal block. It will not work over computer USB power due to power constraints
  • When connected to the cell network you should see a slow flash on the cellular module's status light - 1 flash every 3 seconds
  • When actively logging you should see the TX light (upper left light on cellular module) rapidly flashing. This may take up to 1 minute for the initial connection.
