COMMUNICATION PROTOCOL FOR REMOTELY CONTROLLED LASER DEVICES
A laser device operating system includes a laser device generating a laser beam when receiving a remote control unit command signal. The remote control unit operates in a public or private mode. In public mode the remote control unit generates a command signal transmitted to the laser device. In private mode the remote control unit generates a unique identifier prepended to the command signal. The laser device operates in a laser device public or private mode. In public mode the laser device responds to the remote control unit command signal or the command signal if transmitted by a second remote control unit. In private mode the laser device operates only upon receipt of the command signal and unique identifier, preventing laser device operation by the second remote control unit if the second unit does not include the unique identifier with the command signal.
