The SBE 36 Deck Unit provides surface power and real-time data acquisition and control for an SBE 19, 19plus, 19plus V2, 25, 25plus, or 49 CTD, or SBE 50 Pressure Sensor, interfacing with a Power and Data Interface Module (PDIM). The SBE 36 remains at the surface, while the PDIM is installed on or near the CTD (the term CTD refers to the listed CTDs as well as the SBE 50 Pressure Sensor). The system allows for two-way communication for the CTD over a single- or multi-conductor sea cable, and provides ample power for auxiliary sensors that may not otherwise be supportable by a battery-powered CTD.
The rack-mountable SBE 36 supplies DC power for the underwater units, decodes the serial data, and passes the data to a computer. The SBE 36 rear-panel switch permits operation from 120 VAC or 240 VAC 50/60 Hz input power. Other features include:
The PDIM completes the underwater interface to the CTD. The PDIM housing is anodized aluminum rated to 6800 meters (22,300 ft) depth.
1. When using the SBE 49: Seasave (real-time data acquisition software) does not allow acquisition of Surface PAR data.
2. When using the SBE 50: Seasave does not support this system; real-time data can be viewed in Seaterm (terminal program). NMEA and/or Surface PAR data (if applicable) is output as raw data.
POWER SUPPLY AND REGULATION
The SBE 36 presents a constant 250 VDC to the sea cable. The PDIM receives this voltage (minus the seacable I-R drop) and regulates it to a constant 64 VDC. This 64 VDC is the input for a high-efficiency DC/DC converter, which outputs +15 VDC. The +15 VDC is the supply voltage to the CTD; approximately 1 amp, in addition to CTD power, is available at the CTD for support of auxiliary sensors.
The SBE 36 is supplied with a powerful Windows 2000/XP software package, Seasoft© V2, which includes:
1. DPSK = differential phase shift keyed, FSK = frequency shift keyed.
2. Seasave also supports acquisition of data from a NMEA device connected directly to the computer.
3. When using the SBE 49 with the SBE 36, Seasave (real-time data acquisition software) does not allow acquisition of Surface PAR data.
