Communication to the Interface Box is through either a high-speed RS-232 port or USB port (both modes are supported). The depth/temperature transducer plugs into the interface box which contains the Signal Processing unit and sonar transmitter/receiver as well as temperature measuring circuitry. The Interface Box is powered with 12VDC through a 10-amp fuse.
