0660880d - miniCTD, miniSVP and miniTIDE

3.3. Power

External 9 – 28V DC input
NB: battery should still be fitted even if external power is being used, to maintain clock
function
miniS VP / miniCTD
miniTIDE
Internal Single "C" cell, either 1.5v alkaline or 3.6v Lithium
miniS VP / miniCTD
miniTIDE
67 days @ 40 sec / 10 min sampling (Lithium)

3.4. Acoustic Frequency (miniSVP)

Single sound pulse of 2.5MHz frequency.

3.5. Memory

Each instrument is fitted with SD memory cards. This provides more than sufficient capacity for the operational life
of the battery pack.

3.6. Output

Units are fitted with both RS232 and half-duplex RS485 communications as standard, selected by pin choice on the
output connector. Protocol is 8 data bits, 1 stop bit, no parity, no flow control.
Baud rate is factory set to 115200. User may choose between 38400, 57600, 115200.

3.7. Operating Modes

miniSVP Continuous output at 1, 2, 4 or 8Hz
Profiling mode, every n.nn dBar, where n.nn is user defined
miniCTD Continuous output at 1, 2, 4 or 8Hz
Profiling mode, every n.nn dBar, where n.nn is user defined
miniTIDE Continuous output at 1 or 2Hz
Burst mode, using a choice of pre-defined patterns
