AS-i
Permissible AS-i cable lengths
The maximum length of any one segment on the AS-i network is normally 100 m (328 ft).
However there are a number of devices that allow the length of network segments to be
extended.
Repeater
A repeater allows the maximum cable length to be extended to 300 m (984 ft) using the
maximum of two repeaters. Slave nodes can be used on both sides of a repeater.
Extender
The extender allows the distance between the AS-i master and an AS-i segment of the network
to be extended to a maximum of 100 m (328 ft). With repeaters connected in parallel, a cable
length significantly longer than 300 m (984 ft) can be achieved. The maximum
span is 500 m (1640 ft). The only limitation of the extender is that slaves can only be used
downstream from the extender.
Extension plug
Using the extension plug, the maximum possible cable length in an AS-i segment can be
doubled from 100 m (328 ft) to 200 m (656 ft). The extension plug is a passive device and is
connected to the part of the AS-i network furthest from the power unit. Only one power
unit is required to power the slaves on the segement up to 200 m (656 ft).
