Chapter 3 Configuring the Adapter
Setting the Data Rate
By default, the adapter is set to autodetect, so it automatically detects the data rate
and duplex setting used on the network. If you need to set a specific data rate and
duplex setting, the value of Parameter 16 - [EN P1 Rate Config] determines the
Ethernet data rate and duplex setting that the adapter will use to communicate. For
definitions of data rate and duplex, see Glossary on
1.
Set the value of Parameter 16 - [EN P1 Rate Config] to the data rate at
which your network is operating.

By default, the adapter is set to autodetect, so it automatically detects the data rate
and duplex setting used on the network. If you need to set a specific data rate and
duplex setting, the value of Parameter 18 - [EN P2 Rate Config] determines the
Ethernet data rate and duplex setting that the adapter will use to communicate. For
definitions of data rate and duplex, see Glossary on
1.
Set the value of Parameter 18 - [ENEN P2 Rate Config] to the data rate
at which your network is operating.

TIP
Auto detection of baud rate and duplex works properly only if the device (usually a
switch) on the other end of the cable is also set to automatically detect the baud
rate/duplex. If one device has the baud rate/duplex hard-coded, the other device
must be hard-coded to the same settings.
