Peripherals Page and Serial Port Control
The VN-Matrix units can pass bidirectional serial (RS-232) data or control signals, such as
for serial control of a projector, across the network. See
"Serial Port
other streams on the network and it is not necessary to have a direct encoder to decoder
relationship.
In Pass-through Control Mode (see figure 40), serial data is passed from one VNC 325 to
another. Data flow is fully bidirectional and is independent of whether the VNC 325 is an
encoder or decoder. Thus, control of external equipment is supported.

Figure 40.
One VNC 325 device must be designated the server. All other VNC 325 devices are then
configured as clients.
Data that is input to the server is sent to all clients simultaneously. Data that is received at
a client is sent to the server. Simultaneous data transfers are processed on a first in first out
basis. Any number of pass-through groups can exist on the same network. Communication
can only take place between a client and a server; one client cannot communicate with
another.
