3.4 Local Unit Installation
To install a Local unit:
1. It is recommended that the PC and other devices are switched off before connection.
2. Using the supplied CPU video/USB cable, connect the Local unit to the CPU as shown
in Figure 4.
We recommend that the Local Unit is connected directly to a CPU
USB port (Root Hub). If the Local Unit has to be connected through an
external hub, you should ensure the hub is self-powered (not bus
powered), or connect a 5V PSU (500mA) to the Local Unit.
3. If you want local access to the CPU, connect the video output(s) on the Local unit to
suitable monitors. Connect a USB mouse and a USB keyboard directly to other USB
ports on the CPU or a connected hub.
4. If you have an audio and serial enabled system, connect the audio cables between the
computer and Local unit as follows:
Computer Local Unit
Audio Out (green) Audio In
Audio In/Microphone (pink/blue) Audio Out
5. If appropriate, connect the supplied serial cable between the serial port on the computer
and the Local unit.
6. For single video units, connect the CATx cable to the INTERCONNECT socket on the
front of the Local unit. For dual-head systems, connect the CATx cables from the
Remote unit to the corresponding INTERCONNECT ports (1&2) on the Local unit (see
Figure 5).
7. Power up the PC.
The Local unit normally takes power through the USB connection. In
video only applications, or when the USB interface has limited power
(from a bus-powered hub, for example), an external 5V PSU may be
required. The power LED will indicate if an external PSU is required
(see page 23).
Please contact Technical Support to obtain a suitable power supply.
