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 Rate Cfg]
determines the Ethernet data rate and duplex setting that the adapter will use
to communicate. For definitions of data rate and duplex, see the
Glossary .
1. Set the value of Parameter 16 - [EN Rate Cfg] to the data rate at which
your network is operating.
2. Reset the adapter (see Resetting the Adapter on page 3-16 ).
Setting the I/O
Configuration
The I/O configuration determines the data that is sent to and from the drive.
Logic Command/Status, Reference/Feedback, and Datalinks may be
enabled or disabled. (Datalinks allow you to read/write directly to
parameters in the drive using implicit I/O.) A ‘1’ enables the I/O and a ‘0’
disables the I/O.
1. Set the bits in Parameter 23 - [DPI I/O Cfg].
Bit 0 is the right-most bit. It is highlighted above and equals ‘1’.
2. If a controller is used to control the drive, set adapter Parameters 35 -
[M-S Input] and 36 - [M-S Output] for Master-Slave Hierarchy.
For details, see Setting a Master-Slave Hierarchy (Scanner-to-Drive
Communication) on page 3-8 .
3. If Logic Command/Reference is enabled, configure the parameters in
the drive to accept the Logic Command and Reference from the adapter.

Autodetect
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.
