New Radio Setup

This document covers the procedure for updating the firmware on the FrSky Taranis X9D-Plus radio, and setting it up to work with the receiver in Cassie.

Setting up Radio

• Put the radio in firmware update mode (press the two horizontal trim buttons toward center and turn on the power switch), and attach to a computer with a USB cable
• Open the OpenTX Companion Software and load the CassieModel.eepe file from the Companion Files folder in the drive.
• On the left hand side of the Companion, there are three download icons (denoted by red downward arrows) for downloading model and settings, radio backup, and firmware. Select each in turn, and specify either TaranisFirmware.bin or RadioBackup.bin as appropriate from the Companion Files folder. The model and settings will be downloaded from the open profile (CassieModel.eepe).
• The opening splash screen can be changed through the firmware download dialogue. Select the FrSkyAgilityLogo.bmp from the Companion Files folder.
• Navigate to the SD card folder drive and replace all folders and files with the ones in SD Card Image folder
• Finally (Do this step last), calibrate the analog inputs on the radio by holding the menu button until the RADIO SETUP screen shows, and pressing PAGE until you get to page 9. Press enter to start the calibration process. First it will find the neutral positions, and then you should move through the entire range of motion for each input.

Pairing the Radio with the Receiver

• Disconnect all wires from the receiver
• Use the jumpers that came with the receiver to channels 1/2 and 3/4 along the top row, and connector 3 (Red, Black, Orange) into one of the bottom sockets, as shown in the pictures below.
• Make sure the the transmission mode is set to D16 in the radio profile (press menu once and then page once to get to the model setup screen, then scroll down until you see the Internal RF settings
• Binding Procedure
• Press [bind] in the radio menu (same menu as the Internal RF settings)
• Press and hold down the F/S button on the receiver
• Power on the receiver via Cassie’s logic power
• Wait for the radio to beep and for the receiver to blink red. This will happen quickly, and the radio will not stop periodically beeping
• Power off the receiver
• Reconnect the wires in the standard configuration and remove the jumpers from the receiver
• Done!
