Description of the KSUG in a
network
(Jumper H must be OFF)
The KSUG will only work in a network if the
KSUA has been correctly installed. To
communicate, the KSUA and KSUG use a
communication protocol which, at level 1, is
based on RS485. The physical connections are
two-wire links which must also have a ground.
In other words, the units must be linked with
three wires. Experience shows that the system
often works with just two wires, An example
of a widely used cable type is FKAR-PG
2*0.5. This is a 2-wire cable with screen. The
screen is used as the ground and should ONLY
