CX8030 / CX8031

Version: 1.6

9.6

Topology

• A bus segment may consist of a maximum of 32 devices (including the repeaters).

• The maximum conductor length of a segment depends on the transmission speed in use and on the

quality of the bus cables being used.

• No more than 9 repeaters may be installed between two devices.

• Stubs are to be avoided, and are not permitted above 1.5 Mbaud.

• The maximum number of devices is 127

• Interrupting the supply voltage from cable ends by switching off the repeater/slave, or by pulling out the

plug, is not permitted.

Fig. 1: RS485 topology with 3 segments and 2 repeaters.
