Chapter 2: Overview 2. Overview Thank you for choosing the ServSwitch Wizard VGA-USB extenders which provide a very effective way to put distance between your computer and its peripherals. The compact casings and ease of use of the modules belie the ingenuity of their operation. Using our proprietary transmission techniques we are able to reliably transfer more signals than ever before along a single length of Category 5, 5e, 6, 7 or 7a twisted pair cabling.
ServSwitch Wizard VGA/USB 3. Installation 3.1 Mounting the modules – desk or rack The modules can be situated on a desk or alternatively, for larger installations, mounted within an optional rack mount chassis. 3.1.1 Desk mount Apply the supplied self-adhesive rubber feet to the underside of the module as shown in Figure 3-1: Figure 3-1. Applying the supplied self-adhesive rubber feet to the underside of the module Page 8 724-746-5500 | blackbox.
Chapter 3: Installation 3.1.2 Rack mount Note: The module switches are not accessible once it is inserted into the rack, therefore, check all settings before insertion. 1 Place the rack securing plate (available as a separate kit) onto the front of the module and secure it with the two countersunk screws. 2 Orient the module on its side so that its labeled face is the correct way up. 3 Slide the module into the required rack position.
ServSwitch Wizard VGA/USB 3.2 Connections Installation of the modules is straightforward and requires minimal configuration in most cases. • Connections at the local module • Connections at the remote module IMPORTANT: The ServSwitch Wizard VGA-USB can be used with other hubs in the system, but please note that the local unit should not be connected to the downstream port of a bus-powered hub due to power constraints.

ServSwitch Wizard VGA/USB 3.2.1.2 USB connections IMPORTANT: The Wizard VGA/USB can be used with other USB hubs in the system, but please note that due to power constraints, the local unit should not be connected to the downstream port of a bus-powered USB hub. Additionally, Wizard VGA/ USB dual-variant local units must always be powered using their supplied power adapter. Please see section 3.2.1.5 Local module power for details.

Chapter 3: Installation 3.2.1.5 Local module power The single- and dual-variant local modules differ in the way that they are powered: • The single-variant local module is designed to derive its power from the host computer via the USB connection. If this is not possible, then use an optional power adapter, available from your Black Box stockist. • The dual-variant local module always requires the use of a power adapter and hence two power adapters are supplied with all Wizard VGA/USB dual-variant units.
ServSwitch Wizard VGA/USB 3.2.2 Connections at the remote module 3.2.2.1 Video connections 1 Where possible ensure that power is disconnected from the computer system to be connected. E 2 Attach the lead from the video display to the video out socket on the remote OTmodule as shown in Figure 3-14: EM R Figure 3-14. Attaching the VGA video display cable [Dual-variant only] Optionally attach the lead from a second video display to the upper video out socket on the dual-variant remote module.
Chapter 3: Installation 3.2.2.2 USB connections 1 Attach the leads of up to four USB devices (two of which are usually a keyboard and mouse) to the sockets located adjacent to the video output connector as shown in Figure 3-16: TE TE MO RE MO RE B A Figure 3-16. Attaching the keyboard, mouse and other USB cables [Dual-variant only] IMPORTANT: When connecting four USB devices to the remote module, ensure that their total power requirements do not exceed 1700mA (1.7A).

ServSwitch Wizard VGA/USB 3.2.3 Dual user configuration You can combine two ServSwitch Wizard VGA-USB extender sets to create a dual user configuration. Such an installation would allow a single computer to be controlled from two different positions, with each position receiving the same audio visual output and having equal and concurrent control over the computer.

ServSwitch Wizard VGA/USB 3.3 Video display (DDC) information The Display Data Channel (or DDC) is an industry standard scheme which allows video monitors to declare their capabilities to the computer’s video adapter circuitry, allowing the latter to optimise their outputs accordingly. Since the widespread adoption of the scheme, video adapters have become increasingly dependent on receiving relevant DDC information during startup, before they will output anything more than a rudimentary video signal.
Chapter 3: Installation O 3.3.1 DDC indications R O E M N O T E L IN K When power is first applied to the local module (either from the computer’s USB port or an optional power adapter) it will search for valid DDC data on its video out connector. During this process, the green indicator (built into the link connector) will flash to indicate its progress: • If no valid DDC information is located, the green indicator will give one very short flash, representing an attempt to read data.
ServSwitch Wizard VGA/USB 3.4 Video compensation The ServSwitch Wizard VGA-USB modules include a video compensation system that allows you to get the best results from your remote video display(s). Using this special mode you can configure: • Cable type - Select the type of link cable used. • Cable length - Enter the length of the link cable. • Video gain - Alter the signal gain for the image. • Color skew - Adjust the timing of each color to fine tune the image.
Chapter 3: Installation 3.4.1 To enter video compensation mode 1 Ensure that the two ServSwitch Wizard VGA-USB units are connected to the computer and powered on. A USB keyboard must be connected to the remote unit. 2 Arrange your test images on the remote screen. Please refer to the section ‘Test images while compensating’ shown bottom left. 3 On the remote unit, click the miniature switch 1 to its ON position.
ServSwitch Wizard VGA/USB 3.4 Video compensation (continued) Once you have entered video compensation standby level, you can choose which adjustments to make. Generally you should set the cable type and cable length options first. Then, if necessary, use the video gain and color skew adjustments to fine tune the remote video image. Dual-variants By default, all video compensation changes that you make will affect both channels equally.
Chapter 3: Installation 3.4.5 To adjust video gain a From standby, use and to decrease or increase the gain level. If necessary, press Gain adjustments are saved automatically. to return to a neutral setting. 3.4.6 To adjust color skew You will only need to use these adjustments if the video image is not sharp after adjusting the cable type and length. Before entering video compensation mode, display the suggested screen content (see Test images while compensating on the previous page).
ServSwitch Wizard VGA/USB 4. Operation 4.1 General use In use, the ServSwitch Wizard VGA-USB modules should be transparent - the system and its peripherals should operate exactly as normal, the only difference being that they are now up to 984 feet (300 meters) apart. In some installations, you may see some ‘shadows’ to the right of high contrast screen characters. This can be caused by an incorrect video compensation setting and it may be necessary to make adjustments to correct this.

ServSwitch Wizard VGA/USB Appendix A. Troubleshooting A.1 Status indicators The green indicators built into the link connectors on each module provide useful feedback regarding the connection and power status: During startup (of the local module) • One very short green flash: no valid DDC information available from a locally connected video monitor, no changes made to stored DDC information.
Appendices Appendix B. Safety Information • For use in dry, oil free indoor environments only. • Do not use to link between buildings. • Ensure that all twisted pair interconnect cables are installed in compliance with all applicable wiring regulations. • Do not connect CATx link interfaces (RJ45 style connectors) to any other equipment, particularly network or telecommunications equipment. • Warning – the power adapter contains live parts.
