BUS OUT for the BCL 558
i
To set up an Ethernet network with other participants with linear topology, the BCL 558
i
makes available another Ethernet interface. The use of this interface drastically reduces the
cabling requirements, as only the first BCL 558
i
requires a direct connection to the switch,
via which it can communicate with the host. All other BCL 558
i
are connected in series to
the first BCL 558
i
, see figure 7.9.
For the connection of two BCL 558
i
, the "KB ET - … - SSA" ready-made cables are
preferred, see table 13.9 "Bus connection cables for the BCL 558i" on page 180.
If you use user-configurable cables, note the following:
Notice!
Ensure adequate shielding. The entire connection cable must be shielded and earthed. The
signal lines must be stranded in pairs.
Use CAT 5 cable for the connection.
Notice!
For the BCL 558
i
as standalone device or as the last participant in a linear topology,
termination on the BUS OUT socket is not mandatory!
