adapter, serial cable, warranty card and manual.
2.connecting the cable
Output Connections: The display unit connect with the HDMI interfaces of device's OUTPUT via HDMI
cable; If use an external sound, connect the audio cable to the OUTPUT's A-OUT Interface;
Input connection: input signal that contain USB, HDMI, VGA, AV, USB can access U disk and play the
videos, pictures inside the U disk and so on. Users connect the signal source to be displayed to the
corresponding interfaces inside INPUT box by a cable according to their needs. L, R is the left and right
channel audio with binding Composite video ; A-IN audio bind VGA signal.
RS-232 connection: RJ45 to RS-232 adapter which standard configuration with product access RS232
port of device, then connect with the control computer via RS-232 line.
Power connection: 12V DC power supply which standard configuration with product insert the DC
12V,so the hardware connection is completed, the machine can normal work after setting.
Power on: After connecting the cable above, the configured power adapter of the device insert into an
AC 100-240V power supply, turn on the power switch, power indicator shows green, indicating that the
device is in working condition; red is on standby;on standby state, press the power key of the remote
control to boot and into the normal working condition.
Chapter IV software debugging
After completing the hardware connection, to switch the power on by of remote control, the red
light is on standby, the green light is turned on. Please setting software through the following steps:
1.double-click the icon to run the control software, interface as follows:

7
2.showing the com port number as shown above , you can click directly the of control software
communicate with computer. If the control software does not show the COM port number, Check the
Windows serial port driver is installed . After installation and displays the port number, then restart the
control software to connect.
3.caption adder settings
In input character which will be displayed, click , click at the where
display subtitles,then look at the display unit, you can see the show and the effect of moving of the
enter caption; you can also click to closed captioning display function. And you can set a
variety of display effect of captions:
3.1.text color, the color of display font , font color contain red, green, yellow, blue, black and white .
3.2.Background color - Text background color contain red, green, yellow, blue, black, white, transparent
color .
3.3.show captions - choose to open, the display unit is displayed subtitle; select Off, the display unit
does not display captions.
3.4.text size - that is, the font size, optionally, small, medium and large sizes.
3.5.text position - subtitle show above the display unit; the caption display at the bottom of the display
unit.
3.6.Font's moving speed - still, text display at the center , do not move; medium-speed,font move from
left to right at medium-speed; fast, text fastly moving from left to right.
4.enable the LED function
Click to enable LED function, image can be scaling and screenshots by this feature.
Horizontal and vertical coordinate starting marked as 0, the rightward, the greater the transverse
coordinates; the downward, the greater the longitudinal coordinates, as shown:

4.1.LED function:
The main role of LED's function is to make a complete video signal compress to show on a part of the
display unit, this feature is mainly used in LED full color, as shown below:
If the user's terminal display is a full-color LED screen, LED screen's pixels of 1680x960, the Send
card's resolution of 1920 * 1080,setting in this example:
1. click OK after output resolution of the upper right corner of the control software set to 1920 * 1080, as
2.enable the LED function;
3.the input image can be displayed in full-screen on LED full-color screen after changing the width of
the LED functional areas to 1680, the height to 960 and click OK.
4.change the image's display position of the large screen by adjusting the X and Y's starting point of
the region. LED sending card's horizontal and vertical coordinates are generally set to 0, some special
places setting depending on the user's demand.
4.2.LED screenshot function
Any part of a complete signal can be intercepted and Zoom to full screen display by LED screenshot
function, as shown below:
image before intercepting intercepting part of the image and full-screen display
If we want cut out a part of the image, you can estimate the starting point of the X lateral coordinates
and Y longitudinal coordinates of the portion of the image, but also to estimate the width and height of
the part of the image that to be intercepted. Adjusting the X and Y starting point, width, height of partion
of LED screenshot by sliding the mouse to change the value after estimating,and click the "OK" button
to complete. After completion, May not be coincided with you purpose of the part of image you want to
cut out,then debugging the + or - key of X, Y starting point, width, height, until fully consistent .
The horizontal and vertical resolution of screenshot features, the resolutions of computer output to
device shall prevail. Such as,if computer output resolution is 1920 * 1080,so the maximum lateral
resolution of 1920 and vertical resolution of 1080,and according to this pixels and ratio of 1920 * 1080

9
to calculate the part of the screen you wanna intercept when screenshot.
As shown, if the computer input resolution of 1920 * 1080, and you want to cut out the 6th part of the
picture,the methods and steps as follows
1.the starting point of the transverse direction-X for 480 and the longitudinal direction Y as 360 of this
part;
2.estimating the transverse width as 480 and the vertical height as 360 of this section ;
3.by the mouse, pulling to the corresponding value and click OK;
4.After completion, May not be coincided with you purpose of the part of image you want to cut
out,then fine tuning the + or - key of X, Y starting point, width, height, until fully consistent .
Chapter V Remote Control Description
