WARNING

UNINTENDED EQUIPMENT OPERATION

z Never assume that your controller is in a certain controller state before

commanding a change of state, configuring your controller options, uploading a

program, or modifying the physical configuration of the controller and its

connected equipment.

z Before performing any of these operations, consider the effect on all connected

equipment.

z Before acting on a controller, always positively confirm the controller state by

checking for the presence of output forcing, and reviewing the controller status

information via SoMachine

Failure to follow these instructions can result in death, serious injury, or

equipment damage.

Description

BOOTING The controller executes the boot firmware and its own internal self-tests. It

then checks the checksum of the firmware and user applications. It does not

execute the application nor does it communicate.

INVALID_OS There is not a valid firmware file present In the Flash memory. The controller

does not execute the application. Communication is only possible through

the USB host port, and then only for uploading a valid OS.

EMPTY There is no application in memory or the application is invalid.

RUNNING The controller is executing a valid application.
