1. Product Description
The PC Live Control System, LT-5100, is a LED control system which is used for controlling building brightness, indoor
and outdoor, as well as playing video. The customers can show contents according to their own ideas，through the
real-time control and transmission by computer, Any image can be shown in the LED screen. Figure 1 is the controller
appearance..
Figure 1
2. Product Features
Synchronous control system by computer，Whatever is shown in the computer also can be shown synchronously in the
LED screen.
Using the latest control technology to overcome the complicate connection shortage. Enable the connection simple, and
the production, engineering and maintenance easy and convenient.
Using standard Ethernet output to enable the transmission distance unrestricted.
Using advanced image processing software technology，no need additional graphic cards and sending cards. It can be
controlled by desktop or notebook PC, very easy for debugging and demonstration.
Contrast control, full color, rich picture stunt display.
It can implement image segmentation and synchronous display, and suitable for large screen and high density display
control.
Nice anti-jamming capabilities and auto-recover after failure.
3. Performance parameters.
A single controller can control max 15360 LED pixels which can form in width and length at will..
Multi-controllers can be used meanwhile to control a larger screen.
Signal output type: SPI (TTL).
Contrast: Every single color has 65536 steps, increase from step 32 in turn, forming 16,777,216 true colors.
Frame rate: 30 frames /s.
Screen refresh rate: 120Hz～3000Hz.
Control mode: Full color synchronous control by computer.

4. Connection Mode
4．1 The connection of computer and controller
The connection of the computer and controller through the Ethernet is shown in Figure 2.
Figure 2
4．2 The connection of controller and pixel screen
Figure 3

LT-5100 PC Real-time Video Controller V7.6 Page 5 of 22
4．3 The connection of controller and digital tube
Figure 4
Connection Description:
1．Each controller has 15 splitters, which are connected with the controller’s ports by using
16PIN line, each splitter has two outlets, total 30 outlets;
2．The splitter outputs TTL signal, max 20m between splitter and the led lights;
3．Each splitter can run max 512 pixel dots. For example: If adopting 16 segment digital tube,
namely an output can control 32pcs of digital lamp tubes, but better control below 20
meters to reach a perfect effect.
4．4The connection of multi-controllers
When a single controller is not enough to control the entire screen, Multiple controllers are
needed to work together, The connection is shown as in Figure 5. At the same time The
controllers shall be identified with number through the dip switch.

LT-5100 PC Real-time Video Controller V7.6 Page 6 of 22
Figure 5
5. Setting Controller Number:
Two ways to set: automatically distribution and manually setting：
1）Put the dip switch at “OFF”, the controller will distribute a respective IP and a serial number for
each controller automatically;
2）Manual setting:
When multi-controllers work together, you need to set serial number to every controller(for
details , pls see《Table 5.1》).Through DIP switch the controller can change its serial number. The
DIP switch has 8 dials, from dial 1 to dial 8,each dial has 2 states，switch to “ON” denoting “0”，
otherwise denoting “1”. 8 dials of the DIP switch compose a 8 binary digit，NO 1 is the highest，
NO 8 is the lowest，the DIP switch is as shown in Figure 6;

LT-5100 PC Real-time Video Controller V7.6 Page 7 of 22
Figure 6
When using a single controller independently, please set the controller number as 0, and its
responding switch state as “00000000”.
The relationship of the serial number of the controller and the IP address of the controller is
shown as in Table 5.1.For example, to No 0, switch state is “00000000”，The corresponding IP
address is “192.168.18.60”；DIP switch state is “01111100”, namely No. 124，Its corresponding IP
address “192.168.18.184” can be found from Table 5.1.
Table 5.1 the IP address correspond to the DIP switch

6. Setting the computer
Ⅰ. In order to read the video data accurately, “DirectDraw” must be forbidden. The
operation method is shown from Figure 7 to Figure 10.
Click on “start”-“run”, input “dxdiag”, click on “OK”.
Figure 7

1). Appear “ DirectX”, click on “Yes”
Figure 8
2). “DirectX”box pops up, select“display” and click on “Disable”
Figure 9: Forbid DirectDraw speedup
Then Figure 10 will be shown which means the option is already forbidden.
Figure 10 the interface of after forbidding
Ⅱ. In order to connect the controller normally，the IP address must be set as follows:
Please set IP to “192.168.18.38”，set Subnet Mask to “255.255.255.0”，definitely can not use
the IP address in Table 5.1 of《the IP address correspond to the DIP switch》.For not affecting
other functions of the computer network, you can use advanced configuration of TCP/IP bundling
several IPs. As shown in Figure 5-5, one network card bundling several IP addresses, of which,

LT-5100 PC Real-time Video Controller V7.6 Page 12 of 22
“192.168.1.2” is used to connect the Internet and other networks. The added IP
address,“192.168.18.38”, is used to connect the controller. For more advanced network settings
and topology planning, please let professional to do.

7．Software operation
The controlling software is pure green software, no need to install, just copy the file
LT-5100.exe to computer
7．1 Start
Double-click on the icon of LT-5100 7.6.exe to run the software which is written in mulit-languages.
First choose the language, as shown in Figure 12，and the screen number as shown in Figure
13.After clicking “ok” it will be shown as Figure 14，The screen No. will be shown. If clicking “start”
or using the in-build broadcasting before the controller is completely activated, it will be shown as

7．2 Configure the software
Each specific screen has different layouts, as a result, the configuration is different, for professional users,
you can fill in each parameter by yourself according to the actual installation; as for beginner, we will set a
configuration file according to customer’s actual screen layout, users can upload the configuration file to the
