Decoder Display Capability
As a decoder, the VNC 200 is compatible with both digital (DVI) and analog (RGB)
graphics sources up to UXGA (1600 x 1200 at 60 Hz, 24-bit color) resolution.
NOTE: By default, sources are displayed at their native resolution and format.
The decoded image may also be scaled by the decoder to match the native
resolution of the local display.
Control Capability

Source control

The VNC 200 provides loop-through connections for the keyboard and mouse of the
source computer. Local keyboard and mouse control of the source computer is fully
maintained while connected to the VNC 200. In addition, keyboard and mouse functions
can be remotely controlled from the viewing station.

System setup and configuration

Low level communications setup of the VNC 200 is achieved using a serial data link
connected to the Remote port. High level configuration is achieved via the network using
the Integrated Web Management System.

Integrated web management system

The VNC 200 incorporates an integrated web management system (web interface). This
allows any VNC 200 unit on a network to be configured via a PC/laptop (on the same
network), using a standard web browser (for example, Internet Explorer or FireFox).
One VNC 200 unit on the network must be designated as a controller. This unit acts as
a server for the web interface and also holds a database of all VNC 200 devices on the
network.
Any VNC 200 unit, whether it is configured as an encoder or decoder, can be used as a
controller.
The web interface includes a full online help system.

Remote Control

RS-232 serial data can be routed between selected VNC 200 units, for example, to provide
remote control of a source.
Network Requirements
VNC 200 uses highly efficient compression algorithms to minimize the amount of required
data transported across the network.
It is, however, crucial to the effective operation of the VNC 200 that sufficient data
throughput can be achieved, especially where multiple sources are being encoded.
The efficiency of a network will be directly affected by the speed and configuration
of each element within its infrastructure, that is, switchers and routers. The VNC 200
will achieve optimum transmission results over a dedicated 1 Gbps network (gigabit
Ethernet). For more general information on networks and network performance, see
“Understanding Network Performance”.
