Details Cat(egory) 5e Cable is an enhanced version of Cat 5 that adds specifications for far-end crosstalk.
It replaced the specification for Cat 5 with the 2001 introduction of the TIA/
EIA-568-B standard. Cat 5e cable performance characteristics and test meth-
ods are defined in TIA/EIA-568-B.2-2001.
RS422 Cables (Cat 5e) (both ends with shielded connectors) from the distribution box to all kinds
of desk and screen modules.

Ethernet Cables (Cat 5e) (both ends with shielded connectors) for use between the SCore host card
and the main screen module (via hub/switch), as well as for HD Link, D21m
control, and networking connections. Since modern hubs and switches have
auto polarity selection, straight-through cables may be used in any case.

* Caution
Connectors are identical on the RS422 and the Ethernet
cables. Make sure not to mix them up since the RS422 sockets
carry DC supply voltage!
