Section 2: Description of MicroTSG
This section describes the functions and features of the MicroTSG, including:
•System description
•Specifications
•Dimensions and connector
•Sample timing
•Baud rate, cable length, and power requirements
•Optional remote temperature sensor
System Description
The SBE 45 MicroTSG is an externally powered, high-accuracy, conductivity
and temperature monitor, designed for shipboard determination of sea surface
(pumped-water) conductivity and temperature.
Communication with the MicroTSG is over an internal, 3-wire, RS-232C link,
providing real-time data transmission. Commands can be sent to the
MicroTSG to provide status display, data acquisition setup, data acquisition
and display, and diagnostic tests. User-selectable operating modes include:
•Polled sampling – On command, the MicroTSG takes one sample and
sends the data to the computer.
•Autonomous sampling – At pre-programmed intervals, the MicroTSG
samples and sends the data to the computer. The MicroTSG does not enter
quiescent (sleep) state between samples.
•Serial Line Sync - A pulse on the serial line causes the MicroTSG to
wake up, sample, and enter quiescent (sleep) state automatically.
Calibration coefficients stored in EEPROM allow the MicroTSG to transmit
data in engineering units. The MicroTSG retains the temperature and
conductivity sensors used in the SBE 21 Thermosalinograph, but has improved
acquisition electronics that increase accuracy and resolution, and lower power
consumption. The MicroTSG’s aged and pressure-protected thermistor has a
long history of exceptional accuracy and stability (typical drift is less than
0.002 °C per year). Electrical isolation of the conductivity electronics
eliminates any possibility of ground-loop noise.
The MicroTSG’s internal-field conductivity cell is unaffected by external
fouling. A plastic cup with O-ring retainer at one end of the cell retains the
expendable AF24173 Anti-Foulant Device.

An optional AC- or DC-powered 90402 - SBE 45 Power, Navigation, and
Remote Temperature Interface Box provides:
•Power and an opto-isolated RS-232C interface for the MicroTSG
•An opto-isolated NMEA receiver for an optional NMEA navigation
device which supports NMEA 0183 protocol, outputting data in GGA,
GLL, RMA, RMC, or TRF format (NMEA navigation device not supplied
by Sea-Bird)
•Power and an RS-232C interface for an optional SBE 38 remote
temperature sensor
•An RS-232C computer interface
Decoded Latitude, Longitude, date, and time and SBE 38 temperature data are
appended to the MicroTSG data stream in the Interface Box. The data is
transmitted to the computer for storage and/or display.
The MicroTSG is supplied with a powerful 2000/XP software package,
Seasoft©V2, which includes:
•SEATERM – terminal program for easy communication and data
retrieval, can send commands to the MicroTSG to provide status display,
data acquisition setup, data display and capture, and diagnostic tests.
•Seasave V7 – program for acquiring, saving, and displaying real-time or
archived data.
•SBE Data Processing – program for calculation and plotting of
conductivity, temperature, data from auxiliary sensors, and derived
variables such as salinity and sound velocity.
Notes:
•Help files provide detailed
information on the software.
•Software manuals on CD-ROM
contain detailed information on
Seasave V7 and SBE Data
Processing.
•Sea-Bird also supplies an older
version of Seasave, Seasave-
Win32. However, all Seasave
instructions in this manual are
written for Seasave V7. See
Seasave-Win32’s manual and/or
Help files if you prefer to use the
older software.
•Sea-Bird supplies the current
version of our software when you
purchase an instrument. As software
revisions occur, we post the revised
software on our FTP site. See our
website (www.seabird.com) for the
latest software version number, a
description of the software changes,
and instructions for downloading the
software from the FTP site.
Note:
See the Interface Box manual for
operation of the MicroTSG with the
Interface Box. The Interface Box can
be added to the system at any time,
and does not need to be part of the
original MicroTSG order.

Sample Timing
The time to acquire the temperature and conductivity varies, depending on the
mode of operation.
Polled Sampling Mode
Polled Sampling Mode is in effect when:
•PCB J1 jumper is set to Normal or Autopower, AutoRun=N, and
sampling is started with Go (if SingleSample=Y) or with a polled
sampling command
Time from end of take sample command to beginning of reply (seconds)
= (NCycles * 0.1336) + 0.459
Autonomous Sampling Mode
Autonomous Sampling Mode is in effect when:
•PCB J1 jumper is set to Normal or Autopower, AutoRun=Y, and
SingleSample=N, or
•PCB J1 jumper is set to Normal (pins 2 and 3), AutoRun=N,
SingleSample=N, and sampling is started with Go
Time to acquire temperature and conductivity (seconds)
= (NCycles * 0.1336) + 0.287
Serial Line Sync Mode
Serial Line Sync Mode is in effect when:
•PCB J1 jumper set to Normal (pins 2 and 3), AutoRun=Y, and
SingleSample=Y
Time from wake-up to beginning of reply (seconds)
= (NCycles * 0.1336) + 1.643
Total Sampling Time
Once temperature and conductivity are acquired, the time to calculate the
desired parameters is not a function of the mode of operation:
•Time to compute temperature = 8.8 msec
•Time to compute conductivity = 15.4 msec
•Time to compute salinity = 83 msec
•Time to compute sound velocity = 35 msec
Total time required for sample =
time to acquire temperature and conductivity
+ time to compute selected parameters
+ time to transmit computed parameters
Notes:
•The time to transmit computed
parameters is dependent on baud
rate. See Baud Rate, Cable
Length, Power, and Data
Transmission Rate.
•For autonomous sampling, if the
total time required for the sample
is greater than the user-input
sample interval (Interval=), the
MicroTSG begins the next sample
as soon as it finishes transmitting
the current sample.
Note:
See Command Descriptions in
Section 4: Setting Up MicroTSG
for descriptions of AutoRun=, Go,
SingleSample=, NCycles=, and
Interval=.

Section 2: Description of MicroTSG SBE 45
12
Baud Rate, Cable Length, Power, and Data Transmission Rate
Baud Rate, Cable Length, and Data Transmission Rate
The rate that data can be transmitted from the MicroTSG is dependent on the
amount of data to be transmitted per scan and the serial data baud rate:
Time to transmit data =
(number of characters * 10 bits/character) / baud rate
where
Number of characters is dependent on the included data and output
format (see Data Output Format in Section 4: Setting Up MicroTSG).
Add 2 to the number of characters shown in the output format, to
account for the carriage return and line feed at the end of each scan.
Include decimal points, commas, and spaces when counting the
number of characters.
Note that the MicroTSG transmits data after it has completed the previous
sample and before it starts the next sample. See Sample Timing above for
information on sampling time.
The length of cable that the MicroTSG can drive to transmit real-time data is
also dependent on the baud rate. The allowable combinations are:
Maximum Cable Length (meters) Maximum Baud
800 1200
400 2400
200 4800 (factory set default)
100 9600
50 19200
25 38400
Notes:
•Baud rate is set with Baud=.
•Real-time output rate is set
with Interval=.
•Output format is set with
OutputCond=, OutputSal=, and
OutputSV=.
See Command Descriptions in
Section 4: Setting Up MicroTSG for
command details.
Example –
What is the minimum transmission time over 100 m of cable with OutputCond=Y, OutputSal=Y, OutputSV=Y, and
OutputFormat=0?
With 100 meters of cable, the MicroTSG requires a baud rate of 9600 or less.
Number of characters (from Data Output Format in Section 4: Setting Up MicroTSG) =
8 (T) + 2 (comma & space) + 8 (C) + 2 (comma & space) + 8 (salinity) + 2 (comma & space) + 8 (sound velocity)
+ 2 (carriage return & line feed) = 40
Time required to transmit data = (40 characters * 10 bits/character) / 9600 = 0.042 seconds = 42 msec
What is the minimum total time required per sample (Interval=), if averaging 4 measurements/sample (NCycles=4)
and operating in Autonomous Sampling Mode?
In Autonomous mode, time to acquire T and C (from Sample Timing above)
= (NCycles * 0.1336) + 0.287 = (4 * 0.1336) + 0.287 = 0.82 seconds
Total sampling time
= time to acquire T and C + time to compute parameters (from Sample Timing above) + time to transmit data
= 0.82 + (.0088 + .0154 + .083 + .035) + .042 = 1.00 second
Therefore, set Interval=1, transmitting 1 sample every second.
