Announcement
S 1 + isaw i r e l e s s v i d e o transmission equipment, pleasep a y m o r e attention totheannouncement to
prevent damagetoterminal equipment andpersonal s a f e t y duetoimproper operation o r usage.
1.Please usecorresponding frequency o f S1+
products inaccordance with local r a d i o regulations and
complywith local r a d i o l a w s andregulations.
2.For first usage, pleasem a k e s u r e thatthetransmitter andreceiver areconnected correctly andthe
antenna isinstalled correctly.
1、 Installation W a r n i n g
1.Before setting upanelectric circuit, theusershould install theantenna andm a k e s u r e thatthe
interface istightened. Otherwise, itw i l l damagetothecircuit.
2.Pleasem a k e s u r e thetransmitter andreceiver supply thevoltage within theprescribed voltage r a n g e .
Otherwise, itw i l l damage tothecircuit.
3.Beabletokeep antenna o f transmitter downvertically andwithout anyobstacles toprevent
shortening communication distance because o f blocking.
4.T h e antenna o f receiver should beabletokeep away from l a r g e m e t a l p a r t s .
5.Please bes u r e touseaspecified typeo f antenna toensure thatthefrequency, impedance ando t h e r
parameters match.
6.Please payattention tokeeping theproper distance between theelectronic equipment tominimize
theelectromagnetic interference.
2、 Usage warning

1.Please make sure that all connecting wires are fastened and connected correctly.
2.There is no entry into any foreign body (e.g. liquid,sand,etc.)
3. S1+ needs to 40 seconds to turn on, after that, can transfer video.
4.Please ensure that there is no interference in the surrounding environment with the
same frequency and high power wireless transmission equipment, otherwise the receiver
may not receive the video normally.
5.If the signal of the ground is poor, try to change the inclination of receiver’s antenna.
6.Using HDMI cable, LCD display and other accessories, select a better EMC shielding
performance of the product as far as possible.
Product profile
S1+ consists of transmitter and receiver. It can support video transmission and data transmission.
Adopted by H.265/H.264 video decode, OFDM modulation technique, S1+ provides lower latency and
smaller bit rate video. It is suitable for UAV and other applications which need to have two functions:
video transmission and data transmission.
S1+ Technological advantage:
Video transmission and data transmission；
Transmission distance reaches 5~10Km；
Input and output by HDMI and supporting 1080p60fps and downward compatible；
Latency is low to 200ms；
The frequency is 1430MHz-1440MHz；
Passed SRRC.

Examples:
Installation and wiring
Take Muti-rotor UAV for an example:
Connection diagram：
Fix the transmitter on the suitable
Station of drone(by 3M plug or strap),
and then install antenna with vertical down.
Next, connect camera and transmitter
with HDMI cable (or with CVBS cable),
and then connect to power.
Attention：
Please ensure to install the transmitter
antenna and fasten it before POWER ON.
Otherwise, it will damage the transmitter.

Receiver connection diagram:：
Installation notes：
1.Keep the antenna away from metal equipment of drone, and the antenna should have wide space
within 20cm to other objects to ensure efficient transmission;
2.Make a proper planning about frequency of all wireless equipment on UAV. Otherwise it will cause
the equipment to be unable to use normally .
Usage
S1+ wireless HD video/data includes transmitter and receiver.
Connect an appropriate antenna to the transmitter and receiver.
Connect and /or apply a suitable power source to the unit.
Connect HDMI cable to LCD display.
After power on, waiting 15 seconds, the connection status indicator lights. The transmitter and
receiver connect successful.
Within 30 seconds, receiver receives the video signal from transmitter.
Video record（Receiver）
Wireless HD video receiver support video recording. The steps are as follows:
1.Insert USB device, HDMI of receiver output “USB device is inserted” .
Connect the HDMI of receiver to LCD display.
And connect the antenna ,fasten it.

2.Start video recording by short press receiver “SW”, and the OSD on the display indicates:
“Recording XX：XX：XX”(XX represent the hour, minute and second of recorded video)
3.To stop recording, please press “SW” again. After finishing recording, video is automatically saved
to USB storage device in “mp4_record”.
4.When USB device is pulled out, OSD on the display indicates “USB Device Removed”.
