This configuration is used in the SoundBar 2 Digital Bar Checker, where a 100 dBar range transducer is used, but the miniSVS may be fitted with a selection of different range transducers up to 6000 dBar. The pressure option also uses a secondary PCB.
2.1.1. Power · Requires 8 – 29V DC input · miniSVS draws approximately 17mA at 12V DC · miniSVS with pressure draws approximately 24mA at 12V DC · miniSVS with temperature draws approximately 20mA at 12V DC 2.1.2. Data Output Units are fitted with both RS232 and RS485 communications as standard.
M60<enter> Unit free runs at 60Hz 3.2. Data Formats Data output is dependent on the parameters fitted to the miniSVS and the output format selected. Pressure data format is dependent on sensor range, and may be any of the following.

3.3.6. MVP Housed Systems (SubConn Male Bulkhead Connector) miniSVS instruments built to operate with MVP equipment can be operated in RS232 or RS485 serial comms modes. In order to operate in RS485 pins 2 to 5 have to be linked. This can be done as a factory build setting and are designated 'Internal' RS485 configuration or as an optional setting externally to the instrument.
5. Appendix 1: FAQ’s Why is the Data Different From My Old CTD Data? Quite simply, the Valeport SV sensor is more accurate than anything else that has previously been available. The CTD formulae (Chen & Millero, Del Grosso etc.) all have errors in them –...
