Connection via the RS485 bus (optional)
According to EIA-RS-485, the QD2 bus interface is designed for connecting
up to 30 network elements with an own QD2 interface.
If the node is configured as QD2 Master (hardware setting on the Central
Unit, Switch S3), another SISA-V (3) appears below the SISA-V. Up to 30
NEs can be connected to this SISA-V (3) via the RS-485 bus. The SISA
address area ranges from 1 to 30. The node number can be identical with
or differ from the SISA node number.
