Connecting to a device at full-duplex
Express 10/100 Stackable Hubs operate at half-duplex. The only way
to connect to a device at full-duplex is with an Ethernet Module.
Connecting to a switch at full-duplex
Not all device manufacturers implement auto-negotiation of duplex
mode. To ensure the Ethernet Module connects to the device at full-
duplex, force the duplex mode to full-duplex.
To force the duplex mode, use the Change duplex button:
1 Long press the Change duplex button. The Auto-negotiate LED
blinks.
2 Short press the Change duplex button. The Full-duplex LED blinks.
3 Long press the Change duplex button. The Full-duplex LED stays
on solid.
4 Configure the device on the other end for full duplex. (See the
device’s documentation for specific instructions.)
To force the speed, follow the steps above using the Change speed
button.
Example configurations
Connecting to a switch at full-duplex
This is an Ethernet Module plugged into a hub running at 100 Mbps.
The module is then connected to a 100 Mbps switch using
CAT 5 TPE cable. The module was forced to run in full-duplex mode.
