Ethernet Configuration
Figure 2-5 shows Remote Video System IP in an Ethernet configuration.
In this environment, the server application drives the remote displays through an Ethernet connection. The
display data is sent in the VT200 data stream format. Instead of communicating with a serial communications
port, the server application now communicates with a virtual communications port—both of these ports appear
identical to the server application so no modifications are required to the server application. The virtual COM
port transports the display data over the Ethernet to the destination Remote Video System IP where it is
received, interpreted, and rendered to the attached VGA display. As in the first configuration, you can attach a
local bump bar or other keyboard device to the Remote Video System IP if desired. In this configuration, one
or both of the serial ports on the Remote Video System IP are now available for use as serial ports. You can map
those serial ports to additional virtual communications ports on the server for the application’s use. The
Remote Video System IP appears to have three serial ports. Actually, there are two native serial ports (serial port
1 and serial port 2) and one VGA/video port.
