VN-Matrix 300 • System Conguration 49
Bit rate and network statistics for the current stream are reported in a tabular form.
z The total column contains counts for the history of the stream.
z The window1 and window2 columns contain counts over user programmable
intervals.
z Megabits/sec — The bit rate received from the current data source.
NOTE: The reported bit rate is for the video stream only. Statistics are available
for Audio and FEC on page 45.
z Packets/sec — The number of data packets per second received from the source.
z Dropped packets — The number of data packets dropped during the associated
interval time. This will always be 0 for TCP streams.
Dropped packets will be counted when using RTP streams on busy networks.
z Interval time — The time over which the previous counts are averaged.
The total column assumes an interval time of infinity. The remaining two times are user
programmable in seconds.

Serial Port Control
Bi-directional serial communications (RS-232) can be achieved between any VN-Matrix 300
units on a network.
Serial data is sent independently of the other streams on the network and it is not necessary
to have a direct encoder to decoder relationship.
Pass-through Control Mode
In this mode, serial data is passed from one VN-Matrix 300 device to another. Data ow
is fully bi-directional and is independent of whether the VN-Matrix 300 is an encoder or
decoder. Thus control of external equipment is supported.
Figure 36. Pass-through Control
A single VN-Matrix 300 device is designated the server. One or more VN-Matrix 300 devices
are then configured as clients.
