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 300 metres apart.

In some installations, you may see some ‘shadows’ to the right of high contrast screen characters. This can be caused by an incor- rect video compensation setting and it may be necessary to make adjustments to correct this. Please see Video compensation in the ‘Installation’ section.

4.2 Dual user arbitration

When using two sets of ServSwitch Wizard VGA-USB modules to allow two users to access a single computer, be aware that arbi- tration between the users is handled by the USB sub-system of the computer. Unlike with other Black Box products, this means that both users can control the computer at exactly the same time and the resulting keyboard and mouse influences will be an amalgam of the two inputs - i.e. a mouse move to the right by one user will cancel out a simultaneous left mouse move by the other. The same is also true when the local module has feed-through peripherals attached to it, adjacent to the computer.

For this reason, the ServSwitch Wizard VGA-USB dual user arrangement is better suited to situations where two users would not often require simultaneous access.

4.3 Peripheral operation 4.3.1 USB

Each ServSwitch Wizard VGA-USB remote module provides four USB outlets, each of which can support USB 2.0 peripherals at speeds up to 12Mbps. The ServSwitch Wizard VGA-USB appears to the computer as a four port USB hub.

If the link between the modules is interrupted, any connected USB peripherals will be automatically disabled and re-enabled once the connection is restored.
