hi welcome to a video from Robojax. in this video we are going to
look at the features of the radiolink 89 nine channel 2.4 gigahertz
rc transmitter well you just plug it in and connect it
it's now rotating but the direction is reversed has some value you can fix that
so this is a package when you receive the package so the shape looks like this
okay so a Chinese certificate whatever it is I don't know what it says
a manual on the cd
so comes with a part I believe this would be the part that
you can switch the sticks from left to right
also we got r9d this is a nine channel receiver
so this is the transmitter it's relatively average size very well set in your hand the
handle is metal that's nice because you can attach a fpv monitor here that's one of the advantage
this is from north America so on the left side we have the throttle as you can see so usually you
distinctly understand the throttle by uh moving it to any position it stays so that's the throttle
so this is the other control that we have look at the back so here we have a connector for some
devices which I don't know at the moment I have to look at the manual
so this uses eight battery to power this up so threshold battery will work this is
with the JST connector here connector is here
and for this transmitter for the nano technology 1.5 uh 1500 milliampere where will work perfectly
so using this servo cable you just plug it in and connect it you can see the positive is on
this side and negative is on this side so positive on the wall negative is outside so is the battery
and the positive on the battery is at the middle
so I’m just insulting it like this
if you incorrectly connect this the transmitter will die immediately
of course unless there is some
fuse to protect it let's turn on the transmitter
okay the best thing that you can see immediately if it has a
color screen many of these values that you see on the screen or color
but that's the screen on this side we have two of the channels connected here so this can be used
very nicely with a gimbal to control a gimbal or position of a camera that is very convenient and
nice we have four switches a b c and d so that the d has two position switch
the same as a has two position switch b is also two position we can see here e f g and h so
this is three position switch so it has three position
this has push so you just push and release this is also a regular switch of two position
this is a three position switch some of the set basic setup of this one
so we can use it with a multi-rotor or quadcopter whatever you have so I’m just turning this on
and then let's go for the model select if you see on the screen if you wait for a few seconds
or sometimes you turn it this on you will see this screen so when you see this screen it me
you see it says that push this this push button so this is a push button with a rotary switch there's
a mode button an end button so I have to push this so that disappears now mood button if you press it
and hold it you will see the basic menu and then if you press it again you will see advanced menu
so let me go back to the basic menu and then go to the with the rotary switch when we go
we can select different options any option that is highlighted is selected it needs to be pushed
so it can be accessed so let's go for the model type
you see here it says reset push for one second or let's go here next for helicopter and then
push now you can change it you will see aircraft and the sound of a multirotor screen also appears
so press for one second and it says are you sure hold it says please wait
so now it's aircraft press end to exit and end again so now we are in multirotor or aircraft mode
let's change the model name because you can have multiple models hold model select
go up press enter and as you can see here if I go to the right select that sorry and then
go to the left that is 15 which is the maximum so you can have one you see multi-rotor model
two is such under a helicopter so this is model one which is multi-rotor I’m just pressing it
come here for model one and then we can change this for quad let's say so press that you see
all this alphabet appears so you select the value you want let's say you want to make this one blank
q u a d q u a d up to e is quad so all of this this should be and deleted so if I if
you lose that time just press that again so I’m pressing that again until move this until you
see that space so that's space it has been selected press and go to the selected again
so I’m going here for q
and then for a
q u a
you
so let's say this is a quad and you accept it
uh press exit and exit and now you see quad so you can have multiple models like quad one
quad two black red whatever now let's to test that I have the receiver here
and I have connected a battery to an esc and to a motor that you can see
and then you pay attention here that says rx that's the receiver voltage which is being
sent through this so the esc is supplying five volts here through the middle one uh to the
to the receiver but the signal goes back through the white wire so when you look at this here the
negative is at the bottom so negative positive and then signal so this is negative positive
and signal so you insert it like that or if my if I put it the white should be at the top
so the third channel is throttle let's let me put that there so you can see it I connect that
the light is here and you see 5 volts so this has a firmware psi 1k which uh prevents it
so I have to have at the zero you see it's now rotating but the direction is reversed
so I have to reverse it now let's see how we can reverse that
so first this is saying the push so push that mode button works into this mode when you press it once
and hold it goes to the basic and press again it goes to the advanced mode I’m pressing it again
in the basic mode this is a rotary switch let's go down so you can select any
option you want and then press the push button to select it so mode and rotary
switch and then push so I’m going at the reverse push it now here you see
I’ll run elevator throttle that's number three throttle is connected to channel
three so that's why I connected the throttle into channel three so that was a third one
so that is the normal I’m pressing it and holding it
now it's blinking normal let's go here are you sure reverse now it's maximum
so now the motor is so and so forth so the other channels or just as you said that
they will just simply work the same way but you have to make sure that you have
to put them in proper values so this is channel one you see by default it has some
value you can fix that the same way and this is channel two is also having some value so
so at the middle you want to make sure that you have zero and channel four is this one okay
five six seven and eight here are auxiliary
for different so you can assign these buttons to work with those channels
now I have connected the motor through esc to the battery
and I’m going to show you how you can assign different switch to different channels so this
is switch a b c d as you can see this is switch e and f and g and h so those are already labeled
I’m connecting it to channel five this is channel five the light is on
and as soon as I connect as you see here you see 5.2 volts let me just disconnect it
that's the voltage of the receiver rx and also look there
so now the signal is coming it's in channel five send channel five press mode button once and hold
it this is basic menu and this is advanced you need to be in the basic with a rotary switch
just come to the auxiliary here and then press it now channel five so here on the
auxiliary you can set all these from channel five and to eight nine and ten is this is the
same software so this doesn't have nine and ten it will be in the other one in the other model
so again so now go to channel five and then press it until the it's blinking so we will
put sw as you can see here motor is rotating because there are different things are working
so that is switch a when you see swa this switch a will work
so how it works is in normal you can see here down and up so we can change the mood of this so
when you when it's down it should be off so let's say
so that is switch a that that works so you can
the same thing you can do the switch b so for the same channel you can set the switch b so
now let's switch b switch b
so you can change up
um
okay so
so here we can come and change the switch
so you see auxiliary one auxiliary two
it can be either normal or fail safe
so how can we assign this one this is variable switch a or switch b so let me just
go here so let's assign any of these knobs to the switch or any of these variable
sliders at the bottom also so
so that's variable a
now
so that is a variable a if you want the b just select it make b here
the v and the same thing if I variable c is on this side
and variable d so the same way you can assign any of those switches let's say different switch h
and I want to put switch h at channel 8. so now I’m connected to channel 8
go to channel 8 here that's switch h
so that is switch h
as you can see it works so
that's it guys
