Remote-Control
Each OverView cDG67-DL projection module can be controlled by a serial interface or by an IR
control unit (IR RCU)
3.7 Contro ller
The projection units of an O
VERVIEW CDG67-DL Display Wall are provided with display infor-
mation by the controller. The controller is available as a standard X-Terminal with exceptional ad-
ditional properties or as a Windows NT/2000 Workstation.
3.7.1 Control ler as X.11 Terminal
The X Window System (also abbreviated to X.11) was originally developed by MIT as a graphic
system for UNIX workstations. In the meantime, it is available on a large number of computer
platforms. These also include operating systems such as VAX/VMS or OS/2 in addition to various
UNIX versions.
The X Window System is divided into two parts: The X client and X server are connected to one
another by a communication system (usually TCP/IP). This division permits execution of the
X server and X client either on the same system or also on different systems connected by a net-
work.
The X server is executed on the controller. It implements the graphic display and handles the in-
puts from the keyboard and mouse. The X clients can be executed also on the controller or on
other systems in the network.
The controller satisfies the X.11 protocol (Rel. 6.), and can thus be used by any X clients, toolkits
and window managers. All X clients (including window managers) use the multi-screen facility
without actually 'knowing' this.
Video and RGB Input
The controller has inputs to which video cameras or recorders as well as monitor signals can be
connected.
Simple Integration
The controller possesses the generally established interfaces (Ethernet, TCP/IP, X.11 protocol),
thus guaranteeing simple integration into existing computer networks.
Blinking
The controller provides blinking colors (frequencies to DIN).
3.7.2 Control ler as Windows NT/ Windows 2000 Workstation
If applications based on Microsoft Windows NT or Windows 2000 should be operated via
O
VERVIEW CDG67-DL, the controller as Windows NT/2000 Workstation is used. The operating
system in this case is Windows NT 4.0 or Windows2000, so O
VERVIEW CDG67-DL is like a PC
with Windows NT/Windows2000 connected to a large monitor. No software modifications are
necessary to run applications on O
VERVIEW CDG67-DL.
The Windows applications are operated by keyboard and mouse of the controller.
Video and RGB Input
The controller has inputs to which video cameras or recorders as well as monitor signals can be
connected.
