K-Bus connections

Connection to the K-Bus Port is by standard Midos 4mm screw terminals or snap-on

connectors. A twisted pair of wires is all that is required; the polarity of connection is not

important. It is recommended that an outer screen is used with an earth connected to the

screen at the Master Station end only. Termination of the screen is effected with the "U"

shaped terminal supplied and which has to be secured with a self tapping screw in the

hole in the terminal block just below terminal 56, as shown in the diagram. Operation has

been tested up to 32 units connected along a 1,000 metres of cable. The specification for

suitable cable will be found in the technical data Chapter. The method of encoding the

data results in the polarity of the connection to the bus wiring being unimportant.

Note:

Figure 34:

Basic communication system

K-Bus must be terminated with a 150Ω resistor at each end of the

bus.

The master station can be located at any position, but the

bus should only be driven from one unit at a time.
