14.7 Cable overview
Please note the maximum cable lengths:
14.7.1 Ethernet interface RJ45 connection
For direct connection between laptop and control ("peer-to-peer") you require a transposed
Ethernet cable ("crossover cable“).
If you establish the connection via your local network (intranet), you normally use a non-transposed
Ethernet cable (patch cable).
Interface Maximum cable length
Ethernet Unshielded 100 m
Shielded 400 m
RS-232-C (V.24) Up to 20 m
Do not use self-made cables (shielding problems, contact problems, short circuits, etc.).
Mark your cable as "transposed" or "non-transposed".
Mark your Ethernet cable as "transposed" in order to avoid confusion.
