The VNM 250 series also supports a reverse audio channel for collaborative applications
where 2-way communication is required.
The VND 250 video output is available only in digital format. It can be configured to display
at the same resolution and refresh rate as the encoder input or it can be scaled to match the
requirements of the display attached to the decoder.
The decoder supports both digital audio, analog audio, or both. The audio output is
independent of the encoder audio source.
User Datagram Protocol (UDP) network data originating from an external source is streamed
along with the video and audio content to the appropriate decoder, where it is extracted for
onward processing.
RS-232 pass-through data transport is full duplex. It can originate at either the encoder or
decoder and may be sent to multiple destinations. It passes through the system unchanged
and may not be recorded.
Figure 1 shows a typical application for the VNM 250.

Figure 1.
A Typical VNM 250 Application
NOTE:
In the setup shown in figure 1, an Extron touchpanel is connected to the LAN-1
port of the VND 250.
Once the touchpanel is connected to the LAN-1 port of VNM 250, the IP Link
controller can receive commands from the touchpanel but can no longer update the
touchpanel configuration.
This setup requires all configuration of the IP Link controller and the touchpanel to be
completed before the touchpanel is connected to the VND 250.
