Flashing Guide

-- Connect your device to the computer as shown in the Connection Guide. Find the COM-port associated with the USB-serial adapter.

-- Open cTn's configurator for Google Chrome and select the COM-port from the Serial Port menu. If you plugged in your USBserial adapter after starting the configurator, click refresh to update the list of detected COM-ports, or click Disconnect if the configurator has auto-connected. Don’t click on Connect: click on Start Firmware Flasher.

-- Select the hardware you are flashing. Note that some receivers can also be flashed with transmitter firmware, allowing them to be used as transmitters with some additional components.

-- Select whether or not to erase eeprom. It is always recommended to leave this enabled unless you know what you’re doing.

-- Click the Flash Firmware button. If the flashing was unsuccessful, check to make sure the correct COM-port is selected, the pins have been connected properly (you may have to swap TX and RX, depending on your USB-serial adapter), the LEDs on the receiver are off for the duration of the flashing (indicating that the device is indeed being flashed), and that the device being flashed is being powered properly. Some 1-watt transmitters draw more power than a USB port can give; in this case the transmitter must be powered by a battery while flashing.
