2.1 Introduction
With the Remote Video System IP (RVS), you can place one or more video displays at remote locations and
control the displays from a centrally-located CPU. For example, in a retail environment, you might have an RVS
at each cash register (or user station) connected via a network to the CPU. At each user station, you will need
one RVS. Each RVS has one VGA or SVGA port (links to a video-display monitor) and two USB ports (connect
to individual USB devices, such as a keyboard, mouse, or touch panel). If you need to connect more than two
USB devices to the RVS at the user station, you can plug a multiple-port USB hub into one or both of the RVS’s
USB ports. You can link multiple RVSes to one CPU.
The RVS connects to a Ethernet network. One RJ-45 Ethernet connector and two serial port connectors (one
DB9 and one RJ-45 connector) are on the RVS’s back panel to use for these connections. You can use one, two,
or all three ports at a user station.
Because it uses Display Over IP technology, this network-enabled video display hub makes it easy to connect
video displays anywhere on a wired LAN, while eliminating the need for locally-attached host PCs. It provides
one VGA or SVGA video port and multiple serial and USB ports for human interface devices such as a
keyboard, mouse, or touch panel. The Remote Video System IP software enables remote displays to
communicate with the host PC, without changing existing application software. Remote displays can be
centrally managed and monitored from a remote server or PC via an IP address.
The Remote Video System IP uses VNC (Virtual Network Computing) client software to provide remote access
to a computer on the network or Internet. This allows the device to communicate with the host PC without
changing existing application software. You must install VNC server or VNC client software on the host PC.
Centrally monitor and manage airport status displays or stadium scoreboards, for example, from a remote
server or PC via an IP address. For details about VNC software (included on the software and documentation
CD-ROM), see
Section 4.3.5
. To assign an IP address, see
Section 4.1
.
Remote Video System IP uses the patented RealPort COM/TTY port redirection for Microsoft
®
Windows,
UNIX, and Linux environments. RealPort software provides a virtual connection to serial devices, no matter
where they reside on the network. The software is installed directly on the host PC and allows applications to
talk to devices across a network as though the devices were directly attached to the host. Actually, the devices
are connected to a RVS device somewhere on the network. The RealPort driver (included on the CD-ROM)
translates serial over IP.
For legacy terminal-based systems, the Remote Video System IP also supports standard terminal emulation. You
can use the Remote Video System IP today in a terminal-oriented configuration and migrate to newer graphic
displays whenever you want.
Configure the Remote Video System IP for terminal emulation or remote access via a setup wizard. To further
fine-tune the configuration settings, monitor performance, and perform administration tasks, use the RVS’s
Web user interface, command-line interface, or Simple Network Management Protocol (SNMP) interface.
For security, the RVS uses one password and one permission level. It also features encryption and SNMP
security.
