Step 6: Enabling the Autobaud Option

If it is desirable to have the BridgeWay automatically determine the network baud

rate, the Autobaud option must be enabled.

• Highlight the BridgeWay module by left clicking on its icon.

• Select the Device menu option and pull down menu.

• Select the Class Instance Editor option. A pop up Message box appears.

Click on Yes. Another screen appears.

• There are several parts to this screen. Make sure the check box titled Val-

ues in Decimal is NOT checked. At the top right is an Object Address

with 3 text boxes. Set the values in these boxes as follows:

- Class set to 3.

- Instance set to 1.

- Attribute set to 64h.

• To the left of the Object Class section is one titled Service Code. There’s a

text box with a pull down selection titled Description. Pull down the

selections and select “Set Single Attribute”.

• The box titled Data Sent to the Device is now available. At the far left of

this box enter a “01” to enable autobaud, or a “00” to disable it. Then

click on the Execute button.

• A message should appear in the Data received from device box saying the

execution was completed.

Note: Changes to the autobaud option configuration do not take effect until the

module has been power cycled.

Note: If the BridgeWay is the only master on the DeviceNet network, DO NOT

enable autobaud. Automatic baud detection requires there to be traffic on the net-

work, there is typically no traffic until the master establishes connections.
