Extension cables
Adding an extension cable longer than 20 m (66.0 ft) to a trunk/tap-off has a direct effect on
the available power for the components connected in the daisy chain. A component can be a
Discussion Device or an Extension Unit.
Use the following table to determine the total number of components that can be connected
to a trunk/tap-off when one or more extension cables are connected to that trunk/tap-off.
–
Limit 1: The maximum cable length for a trunk/tap-off is 100 m (328.0 ft). This includes
all extension cables (including the first 20 m (66.0 ft) of extension cable) + the Discussion
Device cables of 2 m (6.6 ft) per device. + the Extension Unit cables.
