The NETLink PRO ETH comes with a shielded category 5 TCP cable with a
length of three meters.
The maximum cable length between two TCP interfaces is 100 meters
according to IEEE802.
If distances greater than 100 meters have to be covered, the use of switches
or hubs is recommended.

If an external power supply is used, please make sure the polarity is correct
and all technical data are complied with.
