A properly configured SBE48 is required for operation in the HullCom/SST subsystem. If the SBE48 does not display the Status info below in response to a DS command, you MUST make the appropriate changes before using the SBE48 in the subsystem.
SBE48 V 1.0 SERIAL NO. 0010 01 Nov 2002 15:39:23 logging data sample interval = 60 seconds number of samples to average = 60 samplenumber = 202352, free = 97241 serial sync mode disabled real-time output disabled temperature = 23.75 deg C
Pinouts at the MCBH5M bulkhead connector are as follows:
pin 1 blk ground pin 2 org commands to SBE 48 pin 3 red +8 to +16 volts pin 4 brn data from SBE 48 pin 5 shd not connected
An internal Ultralife Lithium Battery Model U9VL (non-hazardous) provides backup power and may be drawn upon when testing or setting up this instrument. If an external supply greater than 9 volts is connected, the SBE 48 will draw from that supply only. With a 12 volt external supply, S/N 0001 drew about 12 ma (average) for 1.1 seconds.
Data are stored in FLASH memory while setup information and calibration coefficients are in EEPROM. Battery or external power is not required to retain this information. The real time clock, however, requires power from either the internal battery or the user's external supply.
A. First setup the equipment:
B. Once powered up and connected via Procomm or equivalent:

STOP (stop logging ) DS (check the number of samples that have been recorded) Alt-F1 (put Procom in the logging mode. xmode, file name, page down) dd1,N (where 1 was the first sample and N is the last) Alt-F1 (stop logging and close file)
STOP (stop logging)
BAUD = 9600 (set baud to 9600) TXREALTIME = N (disable real-time output) SYNCMODE = N (disable serial sync mode) DDMMYY=220800 (Set date - 22 August 2000) HHMMSS=123456 (Set time - 56 seconds past 12 hrs and 34 min - use UMT) INTERVAL=60 (sample temperature once per minute (i.e., every 60 seconds) NAVG=60 (To keep an hourly running average of 60 samples) SAMPLENUM=0 (sets the memory pointer to 0) DS (check that the setup is as desired)
Here are some typical responses to commands. Note that the DC command yields the calibration coefficients established during calibration.
