SETTING PARAMETERS

Modbus settings as the RS485/IP interface connected on the same
bus.

- Connection: RJ45, pin 4(-), pin5(+), pin 8(SG)
- Bit rate: 1.2 / 2.4 / 4.8 / 9.6 / 19.2 /38.4 / 57.6 / 115 kbps

ADDRESSING
Addressing can be done:
■ Locally on the product
- addressing from 1 to 9 using the selector.
■ Via software
– addressing from 1 to 247,
– the selector then stays on 0.
The CX³ EMS bus connection specifications are common
to all CX³ EMS products and are detailed in the product
data sheets.
Local setting using the selector takes priority over
software Setting parameters. In the event of
malfunction, check that the selector is definitely on zero.
