If the `transmit` field is 0, the sonar will not transmit after locating the transducer, and the `data` field in the `device_data` message reply will be empty. If the `transmit` field is 1, the sonar will make an acoustic transmission after locating the transducer, and the resulting data will be uploaded in the `data` field of the `device_data` message reply. To allow for the worst case response time the command timeout should be set to 4000 msec.",
