7.3.4 BUS OUT for the BCL 358
i
To set up an Ethernet network with other participants with linear topology, the BCL 358
i
makes available
another Ethernet interface. The use of this interface drastically reduces the cabling requirements, as only
the first BCL 358
i
requires a direct connection to the switch, via which it can communicate with the host.
All other BCL 358
i
are connected in series to the first BCL 358
i
, see Figure 7.9.
If you use ready-made cables, note the following:

NOTE
Ensure adequate shielding. The entire interconnection cable must be shielded and earthed. The
signal lines must be stranded in pairs.
Use CAT 5 cables for the connection.
NOTE
For the BCL 358
i
as stand-alone device or as the last participant in a linear topology, termination
on the BUS OUT socket is not mandatory!
