PC interface keyboard/mouse (Long Distance) X27

This interface is used when the computer system and the control panel are separated by
more than 5m. The mouse and keyboard signals are transmitted via a common cable. A
standard CAT5/6/7 Ethernet cable with an RJ45 connector is used. If this interface is used
the PC must have a corresponding receiver which can convert the incoming signals back to
standard keyboard and mouse signals (see Fig. 5, page 49).
