MXT-5G8-S1 Manual
MXT-5G8-S1 is a 25mW analog video transmitter integrated with a
800TVL minimal illumination camera. It not only supports OSD signal input,
but also supports MX-SmartVTX protocol(compatible with SmartAudio),
moveover, it can switch automatically to video signal input source when
MX-SmartVTX or SmartAudio is detected
VTX Features：
1）Power supply：3.5~5.0V;
2）Current consumption：360mA/3.5V，240mA/5.0V;
3) VTX output power：25mW;
4）General used 40CH working frequencies globally;
5) Integrated with Low-pass LC filter;

6）Supporting OSD signal input;

8）Switchable video signal input source;
9）Size：22.5*13.5*40mm(L*W*H);
Note: 1) MX-SmartVTX is a protocol for connecting between VTX and flight
control board, through which customer can set up working frequency and power
graphically, besides, MX-SmartVTX is compatible with SmartAudio.

Button operation:

The button on VTX board has three functions or use ways on MXT-5G8-S1:
set up Channel, set up band; set up video signal input source. Connect power,
press SW 2 seconds after LED working frequency indication is finished, VTX
will enters set up menu, and two of the LEDs will indicate the present menu
state. The operation way is as the following:
1) Set up Channel: Long press SW 2 seconds till blue LED is on then release
SW, enters Channel set up mode (red LED flashes one time), short press
SW selecting Channel----the number of the blue LED flashing times
indicates the present Channel value;
2) Set up Band: Long press SW 2 seconds till the blue LED is on and then
release it, enters Band set up mode (red LED flashes twice), selecting
Band by short pressing SW---- the number of the blue LED flashing
times indicates the present Band value;
3) Exit and save: Long press SW 2 seconds till the blue LED is on then release
SW, red and blue LED blinks 5 times alternately, indicating set up mode
of VTX exits and the changed parameters are saved.
Menu structure for button pressing:

Set up video signal input source (for connecting an outside OSD):
MXT-5G8-S1 supports two video signal input sources: one is from the
internal analog camera MX-CAM01; The other is for outside video signal input
source such as OSD signal, under this mode, the video signal from internal
MX-CAM01 will be overlapped to the outside OSD and then input
MXT-5G8-S1.
Press SW, connect power ( the blue LED light indicates internal MX-CAM01
video signal, the off-blue LED indicates the video signal from outside), then
release SW, video input signal source will be exchanged alternately one time.
Since then, when it is powered everytime, the blue LED light indicates the video
signal from internal MX-CAM01 and the off-blue LED indicates video signal
from outside.

Besides: As soon as MX-SmartVTX is detected by MXT-5G8-S1,
MXT-5G8-S1 will change its video signal input source to outside. If customer
wants to make the outside video signal as default input source, customer needs
set up it manually.
Note: 1) When the video signal from internal analog camera MX-CAM01 is
as input video source, and also is connected video signal from outside at same
time, the image would turn obscure, it is normal, do not worry.
2) When video signal from outside is as input source, if no image comes
from the analog camera MX-CAM01, please check if the connection is correct
or the OSD is NTSC.
MX-SmartVTX Protocol:
MX-SmartVTX protocol is a convenient operation for setting up VTX
working frequency and power on OSD display through radio, it is a solution for
connection between VTX and flight control board., which is very simple and
direct way.
For using this function, please connect RXD on VTX to TXD on UART3 or
UART6 of flight control board first, turn on SmartAudio function on flight
control board as the following(Note: MX-SmartTX is compatible with
SmartAudio):

Then enter set up mode according to guided message on OSD, and enter set
up menu for VTX, VTX will save the data automatically as soon as the setup is
effective(red and blue LED flashes 6 times in turn).

Indication for MXT-5G8-S1 VTX working frequency
LED flashing state indicates current working frequency when VTX is powered.
LED Indication function:
MXT-5G8-S1 indicates different working state through two color LED lights
which is simple and efficiency. Flashing times of red LED indicates different
option, flashing one time indicates Channel, flashing two times indicates Band,
Flashing times of blue LED indicates the value of the option.
Red LED
Option:（Channel）,（Band）, VTX power
Blue LED
value of the option
Example: Channel 5, Band B, the LED flashes like the following:
●1x Red & 5x Blue = Channel, 5
●2x Red & 2x Blue = Band, 2 (=B)

Ports description:
Note: Video Out is signal output from internal analog cam MX-CAM01, RXD
is MX-SmartVTX protocol or SmartAudio protocol signal cable, EX video IN is
Video signal input from outside (normally is for OSD input), GND is for ground
cable.
