Operation
Operating the receiver is simple. Two push buttons are used to select the
frequency band, and the channel required. They are also used to set up user
configurable settings. After applying power, and provided the ‘auto’ setting for the
low voltage warning is selected, it’ll beep the number of LiPo cells it has detected.
So two beeps is a 2S LiPo and the low voltage warning is set to 6V, three beeps is
a 3S LiPo and the low voltage warning is set to 9V.
The Uno 2400 A/V receiver can tune to 13 unique frequencies in the 2.4GHz
Amateur radio, and ISM bands. All of the channels from the popular ‘Lawmate’
2.4GHz transmitters are supported, along with frequencies used in earlier
ImmersionRC 2.4GHz equipment (also known as the 2.4GHz ‘Airwave’ band).
When the low voltage battery alarm is triggered the receiver will start to beep
indicating you need to charge or change the battery. Furthermore it’ll also beep
when the input voltage is too low, less than 5V or too high, more than 13V. At
voltages less than 5V it will not work reliably, at voltages over 12V it will run hot
over a longer period of use, so this is not recommended. The power input is
reverse polarity protected; however it is good practice to always check polarity
prior to applying power. The Uno 2400 A/V receiver power connector is center pin
positive.
Programming
The Uno 2400 A/V receiver can be configured to store user selected configuration
settings. The selected band, and channel will always be stored so at power up it
defaults to the last selected frequency.
Other settings that can be configured are:
●Low voltage alarm threshold
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.
