Switch 1: Ethernet Auto Sense
To configure the unit for full auto sense capability or limited auto sense capability, push the first toggle switch
up or down. Full Auto sense capability consists of standard Ethernet Auto sensing (100BaseT full duplex,
100BaseT half duplex, 10BaseT full duplex, and 10BaseT half duplex). Limited Auto sensing capability con-
sists on only auto sensing for 100BaseT half duplex, 10BaseT full duplex, and 10BaseT half duplex. The lim-
ited auto negotiation feature is used when an Ethernet device does not comply with IEEE 802.3x (back
pressure flow control) at 100M full duplex
.
Refer to
