Flashing the OrangeRX LRS 433mhz JR module for Taranis.

1) Download Chrome

2) Add openlrs configurator to chrome (Search for openlrs configurator in chrome)

3) Connect TX to USB Serial adapter

IMPORTANT: Must be set to 3.3 volts, NOT 5 volts!!

I used this one from ebay:

FT232RL FTDI USB 3.3V 5.5V to TTL Serial Adapter Module for Arduino Mini Port

You can see the pin labels if you look really close. But, here they are

from top to bottom:

DTR

VC (+ voltage)

CTS (unused for this)

GND (ground)

ANTENNA MUST BE CONNECTED!!!!!!!

Connect this to the TX Via the 6 pins by the antenna (Left side

in pic). I used male-male servo connectors.

IMPORTANT: I could only get the connection to work by

connecting the USB rx to the TX TX pin. And the USB TX

pin to the TX RX pin.

TX USB

DTR to DTR

TX to RX

RX to TX

3.3V to VC

GND not used

GND to GND

4) Connect USB to computer USB port. Both Windows 7 and XP worked for me.

The system should automatically install the drivers. If not, get them from here:

5) Open Chrome configurator (under chrome apps)

6) Click on Firmware Flasher

You will not have success using connect button until tx is flashed.

7) Choose your firmware I tried the “openlrsngtx”, but couldn’t get transmitter to transmit afterwards. So I chose to use flytron m2/m3. This worked fine. 8) Flash the firmware. 9) Click the connect button to flash the receiver, but… I had to disconnect the GND lead on the tx and plug it into the taranis transmitter – USB doesn’t have the power needed for the transmitter. I could only flash the receiver by following this procedure. a) Have a battery and an ESC ready and plugged into the RX channel 1.
