1.0 Product Description  
Meridian’s RGB-T/R product is part of Meridian’s new DigiView product family. This state-of-the-art, high  
performance video transmission system transmits fully-compliant DVI, RGsB or RGBHV signals over one,  
multimode fiber. Optional DVI adapter cables allow easy interface to standard video connection interfaces on  
computers, monitors, switches, etc. The RGB-T/R provides real-time, digitized transmission of DVI, RGB and  
H&V sync signals. Because it transmits signals in real-time, no video information is lost and is a perfect solution  
for dynamic video signals with crystal clear video and no color pixel skewing.  
Having both DVI and RGB input/output capability, this system offers an easy upgrade path from RGB to DVI  
systems with the same modules. With this dual input/output capability, the user can easily interface RGBHV  
sources to DVI monitors and also DVI video sources to standard RGBHV monitors and video switches. The  
user can further enhance the video performance with the use of the computer USB interface. This data channel  
allows the user to adjust brightness, contrast, H&V position, picture sharpness, color, etc.  
This product uses Meridian’s standard 1-slot wide chassis mount card assembly and plugs into the following  
Meridian chassis: SR-500/S, SR-1000/S, SR-1200/S, SR-1500/S, and SR-2001 & SR-2000 series 19”  
equipment chassis.  
2.0 Installation  
The RGB/DVI series products are one-slot wide cards and, as such, occupy one slot in Meridian’s standard  
chassis (SR-500/S, SR-1000/S, SR-1200/S, SR-1500/S, and SR-2001 & SR-2000 series 19” equipment  
chassis). To install in the chassis, orient the card with the Meridian logo at the top of the module and slide onto  
the top and bottom card guides in the chassis. Press securely on the top and bottom of the module to ensure  
that it is fully seated in the chassis so that the electrical connector mates with the chassis-mounted  
motherboard. Once installed, manually tighten the two thumbscrews located at the top and bottom of the card.  
Do not use tools to secure these and do not over tighten.  
Note: A fully populated subrack should have forced-air cooling to avoid excessive heat buildup inside the  
chassis. A fan assembly tray (P/N FA-2000/1) with three (3) fans is available from Meridian and should be  
installed under the 19" SR-2000/1 whenever possible.  
2.1  
Fiber connections  
There is one ST style fiber connection interface on the transmitter and a corresponding ST style fiber  
connection on the receiver. These modems are designed for multimode fiber (either 62.5 or 50 micron core  
diameter fiber). The maximum fiber distance is listed below:  
Fiber type  
62.5/125um  
Maximum distance  
300 meters  
50/125um (standard performance)  
50/125um (high bandwidth)  
1000 meters  
2000 meters  
If the fiber distance is larger than that listed above, the video signal quality will be compromised and may not  
operate properly.

3.1  
RGB resolutions & refresh rates  
Meridian’s RGB-T/R-0 transmission system is designed to automatically sense and configure itself to work with  
many of the standard video resolutions and screen refresh rates. When first connected to an RGBHV video  
source, the transmitter/receiver pair will determine the incoming signal characteristics, search its internal  
firmware database and modify the characteristics of the system to properly encode, transmit and decode the  
signal. This initial recognition will cause the monitor’s display to go blank for approximately 1 second while the  
system synchronizes with the incoming signal. Once completed the video transmission will continue.  
The Resolution/Refresh rate table Appendix 1 lists the various video resolutions and refresh rates these  
modules support – at the time of this writing. If needed, please contact Meridian for an updated list of the  
resolutions/refresh rates this product supports.  
3.2  
RGB Video Adjustments  
There are occasions where the resolution of the video source does not exactly match the resolution of the  
monitor or minor adjustments in color, contrast, picture position need to be made. In this case, the quality of the  
video may be somewhat compromised. In order to correct this, the RGB-T/R modules can be adjusted slightly  
to make minor corrections in the quality of the video signal. These adjustments include Horizontal/Vertical  
position, color, brightness and contrast. The steps below identify the proper procedure for installing and running  
the supplied software.  
There are no physical hardware adjustments on this equipment. All of the adjustments are made with the  
supplied software that can be installed on your Windows 2000/XP computer. Please follow the instructions  
below on the software installation.  
RGB-HV Interface software installation  
1. Insert the card into the chassis or card cage and turn the RGB-HV transmitter’s power supply  
2. Insert the USB cable into the USB connector on the transmitter’s front panel and into an unused USB  
port on your computer (This supports either USB1.1 or USB2.0 ports)  
3. Follow the various screen prompts to install the software from the CD supplied with the product.  
4. Once installed you can go to Windows Device Manager (Ports (COM & LPT)) to ensure that the  
appropriate COM port has been installed  
5. Click START button on task bar, then Programs and choose RGBCARDINTERFACE program. The  
interface should come up. Select choose the appropriate com port. If necessary, you can select an  
alternate port where the hardware resides.  
6. There are three (3) tabs on the top of this window – “File”, “Settings”, and “Presets”. Click on the  
“Settings” tab only. The “Display Adjustment” screen will appear.  
7. The only adjustment that may need to be made is Phase Adjust. This may need adjustment if some  
level of unwanted ‘ghosting’ or vertical bars appears on the display. Normally, no adjustments will be  
necessary.

3.3  
RGB to DVI conversion  
These modems are capable of operating in both RGBHV & DVI modes. Both the Tx & Rx  
units can be individually configured to transmit/receive either RGBHV or DVI. In order to do  
this, one switch on the Tx and Rx boards must be set. The table and figure below show the  
location of this switch on the circuit board and the proper configuration of the switch for the  
desired mode of operation.  
RGB/DVI Selector Switch

The photo below shows the location of the bank of switches. The only switch in this bank of  
10 switches that needs to be configured is Switch #1 (far left switch). The default position is  
ON (up) for RGB operation. Each of the Tx/Rx modules can be configured individually so that,  
if desired, you can make a conversion between RGBHV & DVI. The above table indicates  
how each of these configurations can be accommodated using this RGB/DVI selector switch.  
This switch bank can be accessed either by using a small screwdriver to reach inside the slot  
module’s cover on the right side. Otherwise, the side cover can be carefully removed (screws  
in each corner of the card) where the switch can then be accessed.  
3.4  
RGsB Input/Output  
These units can also be used to transmit and receive RGsB (RGB w/sync on Green) video  
signals. The selector switch on the appropriate Tx/Rx units must be set to transmit or receive  
this signal. In order to input or output an RGsB video signal, both switch 1 & 2 must be in the  
ON (down) position.
