Making Remaining Connections

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 (B on figure 2).

NOTE:

 

The RS-232 Over LAN port also connects relay contacts that turn on when a

 

 

critical alarm occurs. See “Filter settings panel“ to define a critical alarm.

Figure 11. Pin Assignment for the RS-232 Over LAN Port

NOTES: 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

Data bits: 8

Parity: None

 

 

 

Stop bits: 1

 

Flow control: None

 

 

 

 

These parameters are configurable to agree with device to be controller (see

 

 

 

Configuring a Serial Pass-through Group“ in the “Operation” section).

LAN Ports

NOTES: 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 “Data Transport Methods” on page 7 for details.

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 Settings” to configure the units.

Items D and E, below, are identified in figure 2 on page 6.

D LAN 1 port — If desired, connect a CAT 6 cable between this port and the network.

NOTE: 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.
