RS-232 Over LAN Port

If you want the VN-Matrix units to pass serial data or control signals, such as for serial
control of a projector, connect RS-232 devices to RS-232 Over LAN port on all codecs that
are hosting controlled or controlling devices. Figure 11 shows how to connect a host device
to the pass-through device to the RS-232 Over LAN port (

Pin Assignment for the RS-232 Over LAN Port
The VNC 325 uses 9-pin D male connectors. You may need an adapter.

The default RS-232 protocol for the RS-232 Over LAN ports are as follows:
Baud rate: 115200
Stop bits: 1
These parameters are configurable to agree with device to be controller (see

• The number of units that can be connected to the network, while still
providing optimal performance, varies depending on the data transport
method used. See
• Do NOT connect VN-Matrix units to an existing network until each is correctly
configured. Incorrect configuration may cause disruption to other network
users. See "Configuring Network

The factory default IP address for this port is 192.168.0.1.
Link (left) LED indicator — Indicates that the codec is properly connected
to an Ethernet LAN. This LED should light steadily.
Act (right) LED indicator — Indicates transmission of data packets on the RJ-45
connector. This LED should flicker as the codec communicates.
