16 Installation & Hook-Up
Figure 2.3 Wiring the AxisLink Connector
When the ALEC is either the first module or the last module on the
AxisLink cable, an external termination resistor must be installed. If
you are using AxisLink in standard configuration, the resistor should
be 150 Ohms. If you are using Extended AxisLink, the termination
resistor should be 300 Ohms. These are in addition to the internal
resistors set by DIP switches 5 and 6 on the ALEC front panel.
IMPORTANT
Anchor the cable so that no more than 2 feet of cable is
left unsupported. The excessive weight of an unanchored
cable could pull the plug out of the connector.
ATTENTION
!
Install the termination resistor only if your ALEC is
either the first or last module on the AxisLink line.
ATTENTION
!
Even though AxisLink and RIO use the same cable, the
connections are not interchangeable. Do not mix
AxisLink and RIO connections. It causes both systems to
not work properly.
