Extended versus Standard AxisLink
AxisLink has two modes of operation: Standard and Extended. In
standard mode the maximum AxisLink cable length for the connected
modules is limited to 85 feet (25 meters). In extended mode modules
can be connected as needed on the AxisLink cable for up to 410 feet
(125 meters). The number of modules that can be connected to
AxisLink is limited to 8 in standard addressing mode where in
extended addressing mode 16 modules may be connected.
Allen-Bradley 845 Encoders
If you are using and Allen-Bradley 845 series incremental encoder, use
the following table to determine the proper setting of the Mode Switch
and DIP Switch 1.

ATTENTION
!
The maximum values for both AxisLink cable length and
the number of available Address nodes, with both
Extended Length and Extended Node selected, were
determined under controlled test conditions. These
values may vary due to field conditions. Allen-Bradley
cannot guarantee these optimal values under field
conditions.
