GMC Turbo System

For those applications that require longer AxisLink cable lengths, the
GMC Turbo offers the AxisLink Extended Length option. The
Extended Length option allows the user to support up to eight nodes
for a maximum end-to-end cable length of 125 m (410 ft) (user
supplied cable). To enable the Extended Length option, set the switch
located between the Flex I/O and AxisLink connectors on the bottom
of the GMC Turbo system module. See Figure 4.7 for the switch’s
location and Figure 4.14 for switch settings.

The Extended Node option allows the user to support up to 16 nodes
for a maximum end-to-end cable length of 25 m (82 ft). This feature
is enabled in GML version 3.9.1 (or higher) with Firmware version
3.5 (or higher).

Important: You cannot use the Extended node option if the

Extended Length option is enabled.
