It is recommended to use shielded twisted copper cable (e.g. SYKFY ). Outside diameter of the

cable must be from 3 to 6.5 mm, maximal length 1200m. The cable must be located at indoor

rooms.

Nominal cable impedance should be 100 Ω, loop resistance max. 240 Ω, cable capacity max.

65 pF/m. Suitable cable is e.g. SYKFY 2x2x0,5 mm

, where one wire pair serves for transmitter

powering and the other pair for communication link.

The cable should be led in one line, i.e. NOT to „tree“ or „star“. Termination resistor should

be located at the end. For short distance other topology is allowed. Terminate the network by a

termination resistor. The value of the resistor is recommended about 120

Ω. For short distance

termination resistor can be left out.

The cable should not be led in parallel along power cabling. Safety distance is up to 0.5 m,

otherwise undesirable induction of interference signals can appear.

Electrical system (wiring) may do only worker with required qualification by rules in

operation.
