Software is loaded from, and data is loaded to, a subsea electronic control module (SEM) including a transceiver 5 connected to a port on processing means 2. The transceiver 5 has a radio frequency input/output coupled to a modem interface A. The wiring of modem interface A functions as an antenna for the transceiver. The modem communicates with internal processing means 2, which implements received commands in the form of ouputs to driver circuits 3. These in turn output to external devices such as control valves through interfaces B. The data from external inputs, such as pressure and temperature measurements, positions of valves etc from a multiplicity of interfaces C is routed through conditioning circuits 4 before entering the processor and subsequent transmission via the transceiver 5 to external transceiver 6 and processor in computer 7. The carrier frequency is in the GHz region and may include BluetoothTM and wi-fi communication systems. |
