Performance

Auto-negotiation

Communication speed (10 Mbps or 100 Mbps) and duplex mode 
(full or half) can be determined through auto-negotiation with 
the attached devices. The Network Jack attempts to negotiate the 
fastest connection possible (100 Mbps full-duplex).

The communication speed and duplex mode can also be 
controlled using the configuration management software.
