Reflashing / ReflashingTheSPEEDBOX20

Updating the SPEEDBOX20 Firmware

This page contains instructions for reflashing the legacy SPEEDBOX20. It is reflashed using the same program as the current SPEEDBOX. For instructions on how to reflash the current SPEEDBOX please click here.

NOTE: The SPEEDBOX20 and the SPEEDBOX use different firmware. If downloading firmware from the website then please ensure that firmware for the correct product is used.

WARNING: Due to hardware differences, early models of the SPEEDBOX20 may not be compatible with the latest SPEEDBOX20 firmware. If your SPEEDBOX20 has a serial number lower than 50 then please contact Race Technology for advice before attempting to reflash it.

To reflash the SPEEDBOX20 firmware you need to run the SPEEDBOX reflash program. The Race Technology software must first be installed onto a PC, either using the CD supplied with the SPEEDBOX20 or downloaded from the Race Technology website. The SPEEDBOX reflash utility is then accessible through the "Programs" heading on the Windows Start menu, under the "Reflash" section of the Race Technology Software menu.

The SPEEDBOX20 should only be reflashed with approved firmware updates provided by Race Technology. The SPEEDBOX20 will only accept reflash commands for a very short period (about 2 seconds) from startup, after which it switches to normal operation. In order to reflash the SPEEDBOX20, the reflash program is started first, and continually attempts to connect to the SPEEDBOX20. When the SPEEDBOX20 is switched on it detects the attempted connection from the reflash program, sends the correct response, and does not switch to normal operation until reflashing is complete. The following sequence of operations must be performed in the correct order in order to reflash the SPEEDBOX20:

1) Ensure that the SPEEDBOX20 is turned off (remove power supply connection to the unit).

2) Ensure that the SPEEDBOX20 wiring loom is connected to the 12-way main connector on the SPEEDBOX20 case and connect the serial connector on the wiring loom to the serial port of the PC. For PCs that lack a serial port, a USB to serial (RS232) adaptor should be used, which are widely available at low cost.

3) Start the SPEEDBOX reflash program on the PC. Select the required hex file with which to reflash the SPEEDBOX20 (this will be a new firmware file provided by Race Technology, with a .hex file extension) and then select the correct serial port.

4) Reconnect the 12V power supply to the SPEEDBOX20 whilst the reflashing program is waiting for a response. Once the power is re-applied the reflash program will indicate that a connection has been established. Press the "OK" button on the dialog to acknowledge this, and the program will then reflash the SPEEDBOX20, whilst displaying a progress indicator. When this has reached 100% the reflash is complete.

5) After reflashing is complete the SPEEDBOX20 must be re-booted. To do this turn off the 12V power for a few seconds and then back on again. The SPEEDBOX20 should then resume normal operation with the new firmware. If the unit should fail to start, it is likely that the existing firmware was erased, but the new firmware was not correctly written. To correct this you will need to repeat the reflash procedure starting from Step 1), above.
