Auto Negotiation on iMcV-LIM
iMcV-LIM modules include the feature Auto Negotiation. When Auto Negotiation is
enabled, the module negotiates as a 100 Mbps full-duplex device. If the connected
device can operate at 100 Mbps full-duplex, a link is established. Auto Negotiation
(DIP Switch #1) is enabled by default.
If the twisted pair port on the other device does not have the ability to Auto
Negotiate or if the 100 Mbps half-duplex connection is desired, then Auto
Negotiation must be disabled. Half- and full-duplex settings must be set manually
and match on does devices.
The following diagram shows a typical application and with three possible
configurations.
End-to-End Connection Switch TX/FX
Half-Duplex Configure HDX manually Auto Negotiation is OFF
Full-Duplex Configure FDX manually Auto Negotiation is OFF
Full-Duplex Auto Negotiation is ON Auto Negotiation is ON
Configure Auto Negotiation on an iMcV-LIM by adjusting the DIP Switch setting (for
unmanaged modules) or via the management software. Refer to the DIP Switch table
for switch location and settings.
AutoCross Feature for Twisted Pair Connection
All twisted pair ports on the iMcV-LIM includes AutoCross, a feature that
automatically selects between a crossover workstation and a straight-through
connection depending on the connected device.
