Notice for connecting the Ethernet TCP/IP interface!
Ensure adequate shielding. The entire connection cable must be shielded and earthed. The
RD+/RD- and TD+/TD- wires must be stranded in pairs.
Use CAT 5 cable for the connection.

BUS OUT
To set up an Ethernet network with other participants with linear topology, the MA
makes available another Ethernet interface. The use of this interface drastically reduces the
cabling requirements, as only the first MA
via which it can communicate with the host. All other MA
the first MA 208i,(see figure 4.5 on page 19).

For the host connection of the MA 208i, the "KB ET - ... - SSA" ready-made cables are
preferred, see table 14.4 Bus connection cable for the MA 208ion page 64.
