Instruction Manual for

Spektrum™ and JR™ Data Interface

Document Version 1.5

Thank you for your purchase! This instruction manual will guide you through the installation and operation of your Spektrum™ and JR™

Interface (the Interface). Please read the entire manual carefully before proceeding. If, after you read the manual, you have further

questions or problems, see the Support page on


for additional information, or email us at

[email protected].

It is extremely unlikely that the installation of the Interface will affect your model’s radio range or control. But, as always
after making an electronics change to your model, it is very important that you range and function test your model once the Sensor is
installed to ensure that there is no impact on your system. Make sure that your “antenna down” operating range is within the
manufacturer’s specifications. See your Radio owner’s manual for the correct procedure for your equipment. DO NOT OPERATE IF

IMPORTANT: Before connecting the Spektrum interface cable to your Spektrum Receiver, ensure that you have configured your
eLogger or Recorder for the Spektrum interface, as described in the “Configuring the Interface with the Windows Application”
section below!

Packing List

Your package should include the following: The Interface cable, and a printed version of this manual. Please check our support web page
for the electronic version of this manual which may be updated if changes were made after printing.

What the Interface Does

For the first time ever, see and hear how your receiver is performing real time, while you fly! The interface provides support for wireless
telemetry and logging of all the Spektrum™ and JR ™ RF link performance parameters, with “FlightLog” compatible RX’s. Just think,
while you do your range check, get instant feedback on the Seagull LCD display about how your RF link is performing. And best of all,
audible ‘beep’ alarms can be programmed on the Wireless Dashboard display, to alert you in real time when things start to go wrong during
flight! With the programmable beep capability, you keep your eyes on your model, where they should be, knowing that your Receiver is
getting a good signal at all times unless alarms sound. Fly with confidence knowing that your radio link is performing optimally!

The Interface gives you access to the following parameters:

Receiver Holds – displays a count of the number of Failsafe Holds that have occurred

Receiver Lost Frames – displays how many frames have been missed during your flight

Receiver Antenna A, B, Left and Right Fades – displays fade (poor signal) counts of each antenna (up to four). This helps you to
determine which of your antennas needs to be repositioned.

NOTE: at this time, the Interface cable CANNOT be used simultaneously with the GPS Expander, as they use the same port. Eagle Tree is
developing a solution to this shortcoming.

Supported Products

The Interface cable is designed to plug directly into the Data port of most “FlightLog” compatible Spektrum™ and JR™ receivers. It will
not work with any other receiver brand or model! NOTE: Eagle Tree has received a report that Spektrum
and JR
receivers will start up in bind mode when connected to our Recorders during power-up, so PowerSafe receivers may
not be compatible.

The Interface works with the eLogger V4 or V3 (not the eLogger V1 or V2), with all versions of our Pro, Glide, Flight, Car and Boat Seagull
and Recorder products that have shipped since 2007, and have a firmware version of 4.XX or higher. If you have a “3.xx” or lower recorder
firmware version, a hardware upgrade is required. Please see our support web page for more information on hardware upgrades.

Steps to Follow

Installation and use of the Interface should be quite easy and enjoyable if you follow these few steps:

Read through the manual to understand the warnings, determine the installation and setup sequence, etc.

Upgrade the Windows Application and Firmware for your Recorder as described in the “Windows Application and Firmware
Update” section below.
