correctly.
Warning
The bus is electrically isolated from the telephone line circuits according to
the EN60950 requirements and its low voltage cannot cause any electrical
accident.
Caution
Find the 3-pin termination resistance connecting jumper between the
main bus connector and lift number switch.
Connect the jumper to the first and last device (CU, splitter or I/O
module) on the bus. Refer to the CU section for more details.
By default, the termination resistance jumper is off.
Warning
Do not set address 0 and 9 to avoid system error.
