Flexibility
Maximum flexibility for location of the Control Panel on the equipment.
The connection from the Control Panel to the PC itself is made via CP Link,
a transmission technology having a data rate in the gigabit range. CP Link
implements transmission segments up to 100 m on a twin-core coaxial
cable. No additional power supply is needed. The CP-Link Interface is
implemented as an ISA and PCI bus plug-in card and is thus usable in any
PC. The PC is also equipped with a graphics card providing an LCD
interface. The PC ports for LC display, keyboard, COM ports, PS/2 mouse
and floppy drive are converted by the CP-Link plug-in card into a high-
frequency serial signal and transmitted via coaxial cable to the Control
Panel. The CP-Link Interface in the Control Panel re-converts the serial
signal for the original PC ports, to which the components of the Control
Panel, such as keyboard, LC display, touch screen, touch pad, PS/2 mouse
and floppy drive are connected, but at a 100 meters longer distance than
would ordinarily be possible. There is a CP-Link channel for each direction
of the communication between the Control Panel and the PC. Two coaxial
cables are laid for this reason.
