LED clusters - last approx. 10 years or more.
Hooded clusters for better sun protection.
Waterproof aluminum cabinet including power supply and main board.

The RGB graphic board makes use of 3 LED pixel technology consisting of Red, Green and the Blue LED’s, each LED is controlled through 256 levels of brightness giving a total of 16 million different colors, a colour depth comparable to computer screens.

The graphic modules are connected to a controller module, which is in turn connected to conventional computer via the VGA card, a portion of the screen is then represented on the graphical display pixel for pixel.  This means that whatever can be displayed on a computer screen can be displayed on a graphical display.

Software;
A program called  *“Animplay” designed by Polycomp©, is used for setting up the computer and the controller via RS232, it allows scheduling of files and loading of various different files to be displayed from MPG’s and AVI’s to BMP’s and JPEG’s.

Live feeds from camera’s and DVD players can also be accommodated through the use of a PCTV card, which captures the incoming signal and displays it on the Graphic display.

Remote connectivity is made possible thought the use of a modem, or a LAN connection, and a program such as **Laplink 200, giving you, as a customer, the ability to dial up to the Display and upload new files i.e. adverts, and make the necessary changes to the settings on Animplay.

Polycomp© has recently introduced a new concept in Graphic Displays, the use of Virtual Pixel technology, which allows the same data to be displayed in a ¼ of the screen size.  The width and height of the image are both shrunk in half creating a new image, which is a ¼  the size of the original image.

Advantages
-VGA compatible Real Time Animation (up to 70 frames per sec).
-Running Text
-Pre-Scheduling of "Graphics" to appear at a certain time, date, speed.
-User friendly menu and ICON based software.
-Graphics from DOS, Windows (*.avi, *.mov, *.bmp etc).
-Interface to Scanner, Video Camera, Modems.

Explanation of each module

• Remote Computer: Responsible for connecting to the Local PC, allowing the user to transfer files to the local computer and uses the remote console facility to change settings on the computer, particularly settings for Animplay.
   

• MODEM – Either an Analogue 56K modem connected  to an analogue tel. tel. ISDN modem connected to a digital line allowing connection speeds of either 64K or 128K,  GSM modem – used in remote locations when there is no access to telephone lines.
   

• LAN Connection – Remote PC can be connected onto a Network and update the local PC via TCP/IP protocol.
   

• Local Computer – Responsible for sending the data to be displayed to the Graphic controller, receives the files to be displayed from the remote PC via program called Laplink 200,    this allows a remote connection either via a modem or a LAN connection.  Uses a program called Animplay to setup and control the Graphic Controller.
   

• Modem – Either an Analogue 56K modem connected to an Analogue tel. line ISDN modem connected to a digital line allowing  connection speeds of either 64K or 128K.
   

• LAN Connection -  Local PC can be connected onto a network and updated via TCP/IP protocol from the remote PC
   

• LAPLINK 2000- This is the software used for remote file access, Loaded on remote and local PC, allows file sharing and allows new files to be uploaded from the remote PC to the local PC, allows the user to gain complete control over the local PC from the remote PC, using Remote Console facility.
   

• PCTV Card*** – This is an additional card installed in the PC, S-Video, Composite or RF input is available, allows live feed from various different sources i.e. DVD, Video, Camera, DSTV, etc...
   

• Animplay – this is a program developed by Polycomp©, and is used  to setup the computer and the RGB Graphic Controller, it allows the user to adjust the settings for the RGB graphic controller, select the particular files to be displayed, schedule when particular files should be displayed.
   

•  VGA Card - Responsible for the output from the computer to the Graphic Controller, the VGA card should have a minimum screen area setting of 640 x 480 pixels, and should have a colour depth of 16 million colours, the less colours used , the less colour depth will be experienced on the graphic display.
   

• Graphic Controller – Responsible for the analogue  to digital conversion of the VGA signal from the computer, and makes use of FPGA technology for the conversion, allowing a fast  and clean signal conversion and processing, which is then sent to the Graphic display modules. Communication with regards setup takes place Animplay via RS232.
   

• Graphic Modules – Contains the Pixels (3 LED’s each) Red, Green and Blue, and logics required to display the data from the controller, each module measures 64 pixels wide by 48 pixels high, these modules are combined together to create a large outdoor Graphic Display.

* Animplay:  This program is responsible for displaying of the pre selected scheduled files on the graphic display screen, various settings and adjustments can be made to the settings.  Various different file formats are accepted and displayed, these are: MPEG, MPG, M1V, AVI, WMV, WMA (all video formats), various picture formats are also supported, amongst these are: BMP, GIF, JPEG, basically any video file format that is supported by Windows Media Player™ is also supported by Animplay.  A dimming setting can be used to change the brightness of the sign, for day and night viewing, making it less harsh on the eye at night and more visible when competing with the sun in the day.  Each of the three different colours can be adjusted to balance the white produced when all three colours are on at the same time.

** Laplink 2000:  A remote connection is facilitated to the local computer from the remote computer via the use of Laplink 2000.  The remote connection is further facilitated through the use of either a modem or a LAN connection.  If a modem is used, it can either be connected to a conventional analogue telephone line (normal 56K modem), digital line (ISDN modem connected at either 64KBPS or 128 KBPS), or in the case of a remote location where no telephone access is available, a GSM modem. Alternatively, if the remote computer and the local computer are relatively close together, a LAN connection can be used, making use of the TCP/IP protocol. (Laplink supports either modem or LAN)

***PCTV Connection: If a live feed is required to be displayed, the PCTV card is installed in the computer, as well as the required software.  A PCTV card has 3 different video inputs, these are: S-Video input, Composite input, RF input.  The S-Video and Composite inputs can be used for inputs from a DVD player, Video player, Digital satellite receiver, video camera and various other units.  The RF input is connected to a RF tuner onboard the PCTV card and allows the program to tune the PCTV card to a particular RF frequency, allowing the viewing of a terrestrial TV station.
