CAT5 Video Display
1
1. What is the CAT5 Video Display system?
The CAT5 Video Display (VDS) system from Minicom broadcasts real-time high-resolution video signals to hundreds of remote display monitors.
The VDS system consists of the following: • Broadcaster + Control Unit
• Line Splitters to expand the system
• Remote units that connect to each remote monitor/computer • Remote Dual Screen connects 2 monitors to the system
CAT5 UTP or FTP cables connect the VDS system. The Remote units can be up to 110m/360ft away from the Broadcaster.
This Quick Installation Guide illustrates the VDS system and explains how to install and operate it.
2. The multi-functional VDS system
You can use the VDS system in the following ways:
(A) Without the Control Unit
The VDS system constantly broadcasts a computer screen to all remote monitors.
(B) With the Control Unit
• Broadcast a computer screen to all remote monitors • Darken all remote screens
• Release the remote screens to allow local monitor viewing (when remote computers are connected).
The screen dark function is useful when carrying out maintenance, changing the broadcast program or in a classroom environment to grab students’ attention.
With both applications broadcast the video up to resolutions of 1600 x 1200 @ 75Hz depending on the cable length.

4. Expanding the VDS system
You can expand the VDS system to 512 Remote units by having 2 levels of Line Splitters. Level 1 Line Splitters can have 8 Remote units or Line Splitters
connected. Level 2 Line Splitters can have 8 Remote units connected. (See page 4).
5. Pre-installation instructions
Note! In the VDS system the CAT5 UTP or FTP cables carry electrical power. Therefore do NOT connect them to any other device. To avoid this we recommend you attach the stickers provided to the ends of each cable.
Place cables away from fluorescent lights, air conditioners, and machines that are likely to generate electrical noise.
6. The VDS cables
The Video cable is illustrated below. Connect the cable as explained.
Broadcaster Video cable
To computer’s Video port
To Broadcaster’s Video In port Connecting an optional remote computer
You have the option to connect the Remote units to a computer, which can be worked on locally. To do so you need to connect Video cable between the Remote unit and a computer. You can order Remote Video cables from Minicom.
Connecting the CAT5 cables
Please note! Connect the CAT5 cables to the Broadcaster and Line Splitter units
when the units are powered off. We recommend that you connect the CAT5 cables
BEFORE connecting the power supply. Power supply
Connect the Broadcaster and Line Splitters to the power supply with the 12 VDC, 2A from the AC/DC adapter provided. The Remote units and the Remote Dual Screen receive 12 VDC, 160 mA via the CAT5 cables from the Broadcaster or Line Splitter.
7. The VDS configuration for a CBT application
The figure below illustrates the VDS configuration with the VDS Control Unit and the optional remote computers. The Remote Dual Screen has no VGA input and is therefore not suitable for CBT applications.
