4. Setup and Installation
This section outlines the steps for installing the FrSky Taranis Q X7 ACCESS Internal RF Board into your compatible transmitter. Caution: This procedure requires opening your transmitter and handling sensitive electronic components. If you are not comfortable with this, please seek assistance from an experienced technician.
- Preparation:
- Ensure your FrSky Taranis Q X7 transmitter is powered off and disconnect any external power sources or batteries.
- Gather necessary tools: small Phillips head screwdriver, plastic prying tool (optional), and a clean, static-free workspace.
- Opening the Transmitter:
- Carefully remove the screws securing the back casing of your Taranis Q X7 transmitter. Refer to your transmitter's original manual for exact screw locations.
- Gently separate the back casing from the front, being mindful of any connected wires (e.g., battery, speaker).
- Locating the Existing RF Board:
- Identify the current internal RF board. It is typically located near the antenna connection point.
- Removing the Old RF Board:
- Carefully disconnect any ribbon cables or connectors attached to the existing RF board. Note their orientation for re-installation.
- Remove any screws holding the old RF board in place.
- Gently lift and remove the old RF board.
- Installing the New ACCESS RF Board:
- Align the new FrSky Taranis Q X7 ACCESS Internal RF Board with the mounting posts inside the transmitter.
- Secure the new board with the screws previously removed.
- Carefully re-connect all ribbon cables and connectors to the new RF board, ensuring correct orientation and a secure fit.
- Reassembling the Transmitter:
- Carefully re-align the front and back casings of the transmitter, ensuring no wires are pinched.
- Replace and tighten all screws removed in step 2. Do not overtighten.
- Firmware Update (Crucial):
- After hardware installation, it is essential to update your Taranis Q X7 transmitter's firmware to a version that supports the ACCESS protocol. Visit the official FrSky website for the latest firmware and instructions.
- Ensure both the internal RF module and the transmitter's OpenTX firmware are updated to compatible ACCESS versions.
5. Operating Instructions
Once the ACCESS RF board is installed and firmware updated, you can begin using the new protocol. This section covers basic operation related to the RF module.
- Binding with ACCESS Receivers:
- Power on your Taranis Q X7 transmitter.
- Navigate to the Model Setup menu.
- Select "Internal RF" and choose "ACCESS" as the mode.
- Initiate the binding process on the transmitter (usually by selecting "Bind").
- Put your ACCESS-compatible receiver into bind mode (refer to your receiver's manual for specific steps).
- Once bound, the receiver's LED indicator will confirm successful binding.
- Range Check:
- Always perform a range check before flying.
- With the model powered on and the transmitter in range check mode (usually a specific option in the RF settings), walk away from the model while observing control response.
- Ensure adequate control range and signal strength.
- Telemetry:
- ACCESS protocol supports advanced telemetry features. Ensure your receiver and sensors are properly configured to transmit telemetry data to your transmitter.
- Monitor telemetry data (e.g., RSSI, battery voltage) on your transmitter's display during operation.
