Recommended twisted pair cables
Recommended twisted pair cables
The signals between the IO card
modules are transmitted using category 5e (or better) twisted pair cables.
NOTE:
It is permitted to connect several segments of a cable connection with patch
panels and connection ports. It is, however, not permitted to connect active com-
ponents such as network switches, hubs or repeaters.
The data transmission is reliable over a distance of at least 80 metres using a regular
standard twisted pair cable (category 5e or better).
The distance that can actually be bridged depends on the quality of the applied
cable. High-quality S-STP cables with an AWG22 wire gauge coding can bridge a
distance of up to 140 metres.
Patch cables with an AWG26 wire gauge coding can only bridge a maximum of 80
metres.
In order to ensure reliable operation even in environments with interferences, use
installation cables with at least AWG24 coding for lengths over 80 metres:
Wire gauge
AWG22
AWG24
AWG26/27
NOTE:
The lengths mentioned in the table above must be interpreted as the sum of
all segments between the devices.
The following cables achieved the best results during test operation:
Up to 80 meters:
Up to 100 meters:
Up to 140 meters:
