Ethernet wiring
A Cat. 5 Ethernet cable should be used for wiring.
For the connection technology transition from M 12 to RJ45, a "KDS ET M12 / RJ 45 W - 4P"
adapter is available that lets you connect standard network cables.
If no standard network cables are to be used (e.g., due to lacking IP... protection class),
you can use the "KB ET - ... - SA" user-configurable cables on the side of the MA 208i, see
table 14.4 Bus connection cable for the MA 208ion page 64.
The individual MA
"KB ET - ... - SSA" cable, see "Bus connection cable for the MA 208i" on page 64.
For unavailable cable lengths, you can configure your cables yourself. When doing so, make
certain that you connect TD+ on the M 12 connector with RD+ on the RJ-45 connector and
TD- on the M 12 connector with RD- on the RJ-45 connector, respectively, etc.
Notice!
Use the recommended connectors / sockets or the ready-made cables (see chapter 14 "Type
overview and accessories").
For further information on the topologies, see chapter 4.5.1 "Ethernet".
