UNEXPECTED RESPONSE/BAD EVENT
The Unacknowledged Write command
received a response from a CAMP server.
You are probably attempting to access a
CAMP server that does not support the
Unacknowledged Write command.
An unexpected event occurred.
If you are accessing a 2572-B, you must have
firmware version 2.0 or greater. Using the
Web browser interface, check the firmware
version. If the version is less than 2.0,
upgrade the firmware.
If you are accessing a 2572 module, the
Unacknowledged Write command is not
supported. You must use a 2572_ for this
application.
If you did not intend to use the
Unacknowledged Write command, change

If this does not correct the problem, the
cause may be a module firmware error.
