Connectors and Pin-Outs

A/V connection

Two Audio/Video outputs are provided on the Duo2400, plus the GS-Link connection.

These outputs are standard 3.5mm 4-pole jacks, compatible with all ImmersionRC and

FatShark products equipped with the same connector.

Video, and Stereo-Audio are available on these jacks, which can be connected directly to

an LCD headset, display, or recording device.

The A/V outputs may also be used to connect to the ImmersionRC iTelemetry dongle, to

decode telemetry data from your model on your smart-phone or tablet (iPhone, iPad, and

Android devices supported).

Power

The diversity receiver works best with either a 2S or 3S LiPo battery. A cable to connect

the battery is provided. You will have to connect your preferred type of battery connector

to the cable.



5



The receiver automatically sets audible low-voltage warnings based upon the type of

battery sensed. See the programming section on how to set additional low voltage

warnings.

Groundstation Link Connection

The Ground Station link is a standard 6-pin mini-din, as used for many years by PS/2 mice

and keyboards.

This connector may be used to power the receiver, control band and channel options, and

also interface to the Video, and Audio output lines.

The ImmersionRC Antenna Tracker v2, currently shipping, includes a compatible

connector.

Instructions on use

Operating the Duo 2400 Diversity Receiver

The Duo 2400 A/V receiver can be configured to store user selected configuration

settings. The selected channel will always be stored so at power up it defaults to the last

selected channel. Other settings that can be configured are:

●Low voltage alarm threshold

●Low Batt 100mV

●Rx Ticks

Programming these settings is accomplished by using the CHAN push button, with

feedback from the internal beeper, in a manner similar to that used by most ESCs

(Electronic Speed Controllers).

To enter the programming menu, hold down the CHAN push button for 5 seconds or

longer. Once the programming menu has been activated, the receiver will start cycling

through the menu options, in the order listed.

To change one of the items, wait for it to be ‘played’, and immediately after, press the

button.

The receiver will then ‘play’ the current value, as a number of beeps, and will then start

from the first option, and play each option until the last. Selecting an option is simply done

by waiting for it to be played and pressing the button briefly.

Rx Switch Tick

1 – Tick Off

2 – Tick On *

Note that * indicates the default value .

For example to change the Low Battery 100mV setting:

Button pressed for > 5 seconds

Dash Dot Dot - second menu item press button briefly to enter setting

Dot - current setting (auto)

Dot - first available option 0.0v press button briefly

Dot Dot - second available option100mV press button briefly

At this point the Low Battery 100mV setting has been changed to ‘100mV’. The module

will now continue with the next item in the menu, and continue to the end of the list. Once

the end of the list is reached, the receiver will automatically exit the programming mode

signaled by two short beeps.

Low Battery Volts and Low Battery 100mV

These two options can be combined to set the threshold at which the low-voltage alarm

sounds.



8



In Auto mode (the default), the receiver will sense the attached battery voltage, and will set

the alarm voltage accordingly (6V for 2S and 9V for 3S LiPo). This mode is designed only

for use with LiPo batteries. For use with NiCD, NiMh, or other batteries, set the alarm

voltage manually, for example:

9.2v set LowBattVolts to 5 (9v), and LowBatt100mV to 3 (0.2v)

10.0v set LowBattVolts to 6 (10v), and LowBatt100mV to 1 (0.0v)

When powering the receiver from LiPo batteries, it is important to note that the discharge

curve is fairly flat, and drops off quickly near the end. Setting a threshold of around 3.0/cell

is relatively safe. It is however highly recommended to perform a ‘dry-run’ after setting the

voltage warning threshold to make sure the low battery warning is set up correctly.

If upon connection of a battery pack the receiver beeps continuously then the low battery

warning is set higher than the voltage from the battery pack, so reset accordingly or

charge the battery pack.

Note that regardless of the low battery alarm settings, a fixed alarm will occur when an

input voltage smaller than 5V or larger than 13V is detected. This safeguards the receiver

from being used with input voltages with which the correct operation cannot be

guaranteed.

Safety Note: Even though this alarm will provide some protection against loss of video

signal during an FPV flight, it is highly recommended to fully charge all battery packs used

before each and every flight.

Rx-change Ticks

When the diversity receiver’s microcontroller switches receivers, it issues an audible ‘tick’.

A useful confidence-building feature when using the receiver, but if you feel the ticking

becomes annoying you have the option of turning it off.

Optimal Antenna Connection

The Duo2400 was designed to be connected directly to the antenna’s RF connector with

as short a cable as possible, or ideally no cable at all.

Months of testing has shown that with this configuration, the best reception will be

obtained. You can even connect the Patch antenna directly to the Duo2400 (please be

careful not to put too much force on the SMA connectors if this mounting technique is

chosen)

Antenna Selection & Placement

The diversity receiver may be used with standard 2.4GHz antennas, equipped with a male

SMA connector. The spacing between the two antennas is not too critical on the 2.4GHz

band, even with two spiroNET antennas placed touching each other, multipathing effects

will be greatly reduced.

Frequencies

The Duo2400v3 supports 20 frequencies, spread over 4 bands. These bands correspond

to various standards commonly used in the 2.4GHz FPV world, and have some history

behind them.
