What Is the ArmorPoint DeviceNet Adapter? 2-11

The baudrate may not take effect until power is recycled or the I/O

modules are reset.

Backplane/Subnet Baudrate performs the following functions:

• Sets the adapter’s Subnet baudrate

• Sends a message to all connected backplane I/O modules. If an

I/O module is set to autobaud, it receives the message but

ignores the new baudrate.

IMPORTANT

Changes to the Backplane/Subnet Baudrate

parameter only take effect if they are downloaded on

an individual basis. (For example, if you change the

Backplane/Subnet Baudrate and download the

changes with additional changes to other features,

the Backplane/Subnet Baudrate remains at the

previous setting.)

Also, this parameter should be set to ‘Do Nothing’

when you download all parameters or when

Automatic Device Replacement is enabled for

the adapter.

If you want to set an I/O module to use a specific

baudrate (i.e., 125, 250, 500), you must first disable

Backplane Autobaud for that module.
