Change duplex button and LEDs
You can determine the Ethernet Module’s duplex configuration and
status from the duplex LEDs. Use the Change duplex button to cycle
among duplex modes.
Attach any Express 10/100 Stackable Hub to the Ethernet Module and
the module will automatically negotiate the correct duplex setting
(always half-duplex). The default duplex mode setting is auto-
negotiate.
