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.

Section 2: Description of MicroTSG SBE 45
Sample Timing
The time to acquire the temperature and conductivity varies, depending on the
mode of operation.
Note:
See Command Descriptions in
Section 4: Setting Up MicroTSG
for descriptions of AutoRun=, Go,
SingleSample=, NCycles=, and
Interval=.
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.
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

Baud Rate, Cable Length, Power, and Data Transmission Rate
Baud Rate, Cable Length, and Data Transmission Rate
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.
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:
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.
• Limiting the IR loss to 1 volt; higher IR loss will prevent the
instrument from transmitting real-time data because of the difference in
ground potential.
• Supplying enough power at the power source so that sufficient power is
available at the instrument after considering IR loss.
Looking at each issue separately:
Limiting IR Loss to 1 Volt
The limit to cable length is typically reached when the maximum current times
the power common wire resistance is more than 1 volt, because the difference
in ground potential of the MicroTSG and ground controller prevents the
MicroTSG from transmitting real-time data.
= 1 volt = IR
V
limit
limit
Where I is the current required by the MicroTSG (34 milliamps at 8 VDC;
see Specifications above).
Maximum cable length = R
/ wire resistance per foot
limit
Example – For 18 gauge wire, what is the maximum distance to transmit power to the MicroTSG?
If this the controlling factor for maximum cable length if wanting to transmit at 1200 baud?
For 34 milliamp current, R
For 18 gauge wire, resistance is 0.0064 ohms/foot.
Therefore, maximum cable length is 29 ohms / 0.0064 ohms/foot = 4531 feet = 1381 meters.
Note that 1381 meters > 800 meters (maximum distance MicroTSG can transmit data at 1200 baud), so IR loss is not
controlling factor for this example.
Example2 – Same as above, but there are 4 MicroTSGs powered from the same power supply.
R
= V
limit
Therefore, maximum cable length is 7.35 ohms / 0.0064 ohms/foot = 1148 feet = 350 meters (this is cable length to
MicroTSG furthest from power source).
/ I = 1 volt / (0.034 amps * 4 MicroTSGs) = 7.35 ohms
limit
limit
= V
/ I = 1 volt / 0.034 amps = 29 ohms
limit
Supplying Enough Power to MicroTSG
Another consideration in determining maximum cable length is supplying
enough power at the power source so that sufficient voltage is available, after
the IR loss in the cable, to power the MicroTSG.
Example – For 18 gauge wire, what is the maximum distance to transmit power to the MicroTSG if using a 8.5 volt power
source to supply power?
Is this the controlling factor for maximum cable length if wanting to transmit at 1200 baud?
MicroTSG’s input power specification is 8 – 30 volts. Therefore, a 0.5 volt IR drop (8.5 volts – 8 volts) would still provide
enough power to MicroTSG.
V = IR 0.5 volts = (.034 amps) * (0.0064 ohms/foot * cable length) Cable length = 2297 ft = 700 meters
Note that 700 meters < 800 meters (maximum distance MicroTSG can transmit data at 1200 baud), so IR drop in power
is controlling factor for this example. Using a higher voltage power supply or a different wire gauge (12, 14, or 16 gauge)
would provide sufficient power at MicroTSG to allow an 800 meter cable length.
Example 2 – Same as above, but there are 4 MicroTSGs powered from the same power supply.
V = IR 0.5 volts = (.034 amps * 4 MicroTSGs) *(0.0064 ohms/foot * cable length)
Cable length = 574 ft = 175 meters (this is cable length to MicroTSG furthest from power source).

Remote Temperature Sensor (optional)
The optional 90402 – SBE 45 Power, Navigation, and Remote Temperature
Notes:
• 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.
• Sea-Bird software (Seasave realtime data acquisition and SBE
Data Processing’s Data
Conversion and Derive modules)
uses the data from the
MicroTSG’s temperature and
conductivity sensors to calculate
salinity, and then uses that
salinity with the temperature from
the remote temperature sensor
to calculate density and
sound velocity.
Interface Box can append the output of an optional SBE 38 temperature sensor
to the output from the MicroTSG. Often, the MicroTSG is mounted in the
interior of the vessel. In this configuration the recorded conductivity is correct,
but the water temperature has changed as it has passed through the plumbing
system. The remote temperature sensor can be placed in a location that
provides more accurate measurement of the sea surface water temperature.
The ideal location for the remote sensor is at the seawater intake (before
the pump) near the bow of the ship. This minimizes contamination of the
surface temperature measurement by the ship’s own thermal mass.
To compute salinity, always use the data from the temperature sensor on
the MicroTSG, not from the remote temperature sensor. Conductivity has
a strong thermal coefficient; therefore, it is critical to know the temperature of
the water when the conductivity sensor samples it in order to compute salinity
correctly. On a typical installation, there may be 20 to 30 meters of plumbing
between the remote temperature sensor and the MicroTSG. As the water flows
through the pipes it changes temperature dramatically, making the data from
the remote temperature sensor an inaccurate representation of the temperature
when the water reaches the conductivity sensor. Use the remote temperature
sensor only to report surface temperature, and to calculate density and
sound velocity (density and sound velocity are a function of salinity
and temperature).

Section 3: Installing System SBE 45
Sea-Bird does not provide detailed installation instructions for the MicroTSG,
given the unique nature of every ship and type of installation. The installation
of the MicroTSG should be done by qualified shipfitters, with the oversight of
a competent ship designer or naval architect. Consider the following:
• The MicroTSG can be mounted anywhere it will fit that is accessible for
maintenance and cleaning. For safety, mount the MicroTSG above the water line.
Note:
The optional Interface Box appends
data from the optional SBE 38
remote temperature sensor to the
MicroTSG data stream.
¾ If the remote temperature sensor is not used, mount the MicroTSG as
close to the seawater intake as possible to avoid thermal
contamination from long plumbing runs. Thermal contamination will
not affect salinity accuracy, but the MicroTSG will report the
temperature of the water when it reaches the instrument.
¾ If the remote temperature sensor is used, the MicroTSG can be
mounted in the ship’s lab or other convenient location.
• Sea-Bird does not recommend or supply a pump. ¾ The pump must provide 10 to 30 milliliter/second
(0.16 to 0.48 gallons/minute) flow.
¾ Pressure at the MicroTSG is limited to 34.5 decibars (50 psi).
¾ Research vessels often maintain seawater delivery systems for a
variety of scientific purposes, including feed to a thermosalinograph.
Many vessels use engine raw cooling water. However, because the
MicroTSG is designed for a flow rate of 10 to 30 milliliters/second,
ensure that most of the coolant flow bypasses the MicroTSG.
¾ Pleasure-boat pumps designed for salt water and for below-fluid level
(non-priming) may be satisfactory, although their flow rates are much
too high (more than 15 gallons/minute). Some method – flow
restricting orifice, bypass, etc. – is needed to reduce the flow rate to
the required level. Additionally, pleasure-boat pumps are not usually
certified for below-waterline use.
• Bubbles in the plumbing of a flow-through system are a common problem
and will cause noisy salinity data. To minimize bubbles:
¾ Place the pump below the water line to push rather than lift the water.
¾ Locate the MicroTSG’s hull intake as deep as possible, as far as
possible from bubble sources (bow wake, propeller, etc.).
• Depending on the chosen design of a permanent seawater supply
(including pump, intake fitting, pipes, etc.), a de-bubbling device may be
needed to separate bubbles from the water before it enters the MicroTSG.
Note that a de-bubbler may cause additional temperature errors for the
MicroTSG’s primary temperature sensor; salinity accuracy (and accuracy
of an optional remote temperature sensor) is not affected. Not all ships
require de-bubblers, but many do for best quality salinity data. Large
single point salinity spikes can be removed with the Wild Edit module in
SBE Data Processing.
• Route cabling as cleanly as possible, avoiding sources of noise. Electric
motors are a particular problem. Avoid routing the cable next to
generators and air conditioners. Cables longer than 3 meters should be
installed inside an earthed metal conduit by a qualified electrician. This
minimizes the potential for external signals to disrupt communication and
ensures that high voltage lines (such as the sea cable) are sufficiently
protected. Cables shorter than 3 meters can be used without shielding
when installing or bench testing the instrument.
• If practical, mount the optional SBE 38 remote temperature sensor outside
the hull. However, the SBE 38 is usually mounted in the remote sensor
mount kit, which has 1-inch pipe threads on each end; plumb the mount kit
into your seawater system. Install the SBE 38 as close to the seawater intake
as possible (before the pump), near the bow of the ship. Since the
installation is below the water line, consult your ship’s engineer / naval
architect / shipyard regarding the actual installation. We cannot offer advice
in this matter as each ship is different and plumbing regulations vary.

Power-Up Jumper Check
The MicroTSG’s Printed Circuit Board (PCB) has a jumper that controls how
the MicroTSG wakes up:
• Autopower (default) – The MicroTSG wakes up when power is applied.
System capability is dependent on the external wiring configuration:
¾ Three wires – This configuration is useful in simple systems where

• Connect the MicroTSG to the computer as described in Communications
a controller applies power, waits for data, and then removes
power. Only three of the four wires (Power, Ground, and Transmit)
are needed for operation, since it is not necessary to command the
MicroTSG to take samples. Note that the MicroTSG does not respond to any commands in this configuration, so initial setup
of the system must be performed with all four wires in place
(see CommandDescriptions in Section 4: Setting Up MicroTSG).
¾ Four wires – With all four wires (Power, Ground, Receive, and
Transmit), the MicroTSG can receive and respond to most
commands. Note that the MicroTSG does not respond to QS in
this configuration.

communications settings, wake up the MicroTSG with the Connect button
on SEATERM’s Toolbar, and then enter QS after the S> prompt.
The response indicates whether the jumper is in the Normal or
Autopower configuration:
¾ Autopower – system returns S> prompt, indicating that the
MicroTSG is not in quiescent (sleep) state.

Section 4: Setting Up MicroTSG SBE 45
Sampling Modes
The MicroTSG has three basic sampling modes for obtaining data: Polled
Sampling, Autonomous Sampling, and Serial Line Synchronization Sampling.
However, commands and the J1 jumper setting on the MicroTSG’s PCB
can be used in various combinations to provide a high degree of
operating flexibility.
Shown below are descriptions and examples of the three basic sampling
modes. Note that the MicroTSG’s response to each command is not shown in
the examples. Review the operation of the basic sampling modes and the
commands described in Command Descriptions before setting up your system.
Polled Sampling
Note:
After waking the MicroTSG, you may
need to press the Enter key several
times and send Stop to interrupt
sampling, depending on how the
instrument was set up the last time it
was used.
On command, the MicroTSG takes one sample of data and sends the data to
the computer.
Examples: Polled Sampling Mode (user input in bold)
Example 1: J1 jumper in Normal position (pins 2 and 3).
Wake up MicroTSG. Set up to wait for command each time MicroTSG
wakes up, and send salinity with data. Send status command to verify
setup. Send power-off command after all parameters are entered.
Assuming that power is always applied:
When ready to take a sample (repeat as desired): wake up MicroTSG,
command it to take a sample and output converted data to computer, and
send power-off command.

Notes:
• After waking the
MicroTSG, you may
need to press the Enter
key several times and
send Stop to interrupt
sampling, depending on
how the instrument was
set up the last time it
was used.
• If using the MicroTSG

Page 34
Section 4: Setting Up MicroTSG SBE 45
Serial Line Synchronization (Serial Line Sync)
Note:
After waking the MicroTSG, you may
need to press the Enter key several
times and send Stop to interrupt
sampling, depending on how the
instrument was set up the last time it
was used.
In Serial Line Sync Mode, a simple pulse (a single character) on the RS-232
line causes the MicroTSG to wake up, take and output a single sample, and
automatically go to sleep (enter quiescent state). This mode is enabled if
AutoRun=Y, SingleSample=Y, and the PCB’s J1 jumper is in the
Normal position (pins 2 and 3).
Example: Serial Line Sync Mode (user input in bold)
(J1 jumper in Normal position – pins 2 and 3)
Set up to take a sample upon receipt of any character and then
automatically go to sleep. Send status command to verify setup. Send
power-off command to MicroTSG after all parameters are entered –
system automatically wakes up and goes to sleep for each sample upon
receipt of a character. Assuming that power is always applied:
(Click Connect on Toolbar to wake up.)
S>SINGLESAMPLE=Y
S>AUTORUN=Y
S>DS (to verify setup)
S>QS
When ready to take a sample (repeat as desired):
(Before first sample, click Capture on Toolbar to capture data to a file – program
requests file name for data to be stored)
(Press Enter key to wake up, sample, and go to sleep.)
When ready to stop sampling or change setup:

Timeout Description
The MicroTSG has a timeout algorithm when jumpered in the Normal
configuration (PCB J1 pins 2 and 3). If the MicroTSG does not receive a
command or sample data for two minutes and AutoOff=Y, it powers down its
communication circuits. This places the MicroTSG in quiescent state, drawing
minimal current. To re-establish control (wake up), click Connect on the Toolbar or press the Enter key. The system responds with the S> prompt.

Data Processing use the same file.
• A new or recalibrated instrument
ships with a configuration file that
reflects the current configuration as we know it. The file is named with
the instrument serial number,
followed by a .con extension. For
example, for an instrument with
serial number 2375, Sea-Bird names
the file 2375.con. You may rename
the file (but not the extension) if
desired; this will not affect the
results.
Seasave and SBE Data Processing, our real-time data acquisition and data
processing software (respectively), require a configuration file. The
configuration file defines the MicroTSG – which parameters are output by the
MicroTSG, and the data output rate - and indicates whether NMEA and
SBE 38 data is to be appended to the data stream. The software uses the
configuration file to interpret and process the data. If the configuration file
does not match the actual instrument configuration, the software will not
be able to interpret and process the data correctly.
To verify the contents of the .xmlcon or .con file:
1. Double click on Seasave.exe.
2. Click Configure Inputs. On the Instrument Configuration tab, click Open. In
the dialog box, select the .xmlcon or .con file and click Open.
3. The configuration information appears on the Instrument Configuration
tab. Verify the output matches the output programmed into the SBE 45,
and the use of the optional Interface Box, SBE 38, and NMEA matches
your system. Click Modify to bring up a dialog box (shown below) to
change the configuration.

Processing Data
Process the data in SBE Data Processing.
Note:
See the SBE Data Processing
manual and/or Help files.
Note:
Although we provide this
technique for editing a .hex file,
Sea-Bird’s strong
recommendation, as described
above, is to always convert the
.hex data file and then edit the
converted (.cnv) file.
1. Convert the .hex data file created by Seasave to a .cnv file in SBE Data
Processing’s Data Conversion module.
2. Once the data is converted, it can be further processed and plotted in
SBE Data Processing’s other modules.
Editing .hex Data File
Sometimes users want to edit the .hex data file before beginning processing, to
remove data at the beginning of the file corresponding to instrument soak time,
to remove blocks of bad data, to edit the header, or to add explanatory notes.
Editing the .hex file can corrupt the data, making it impossible to perform
further processing using Sea-Bird software. We strongly recommend that
you first convert the data to a .cnv file (using Data Conversion in SBE Data
Processing), and then use other SBE Data Processing modules to edit the
.cnv file as desired.
The procedure for editing a .hex data file described below has been found to
work correctly on computers running Windows 98, 2000, and NT. If the
editing is not performed using this technique, SBE Data Processing may
reject the edited data file and give you an error message.
1. Make a back-up copy of your .hex data file before you begin.
2. Run WordPad.
3. In the File menu, select Open. In the Open dialog box: for Files of type,
select All Documents (*.*). Browse to the desired .hex file and click Open.
4. Edit the file as desired, inserting any new header lines after the System Upload Time line. Note that all header lines must begin with an asterisk
(*), and *END* indicates the end of the header. An example is shown
below (for an SBE 21 data file), with the added lines in bold:
* Sea-Bird SBE 21 Data File:

Section 6: Routine Maintenance
and Calibration
This section reviews corrosion precautions, conductivity cell cleaning and
storage, replacement of the Anti-Foulant Device, and sensor calibration. The
accuracy of the MicroTSG is sustained by the care and calibration of the
sensors and by establishing proper handling practices.
Corrosion Precautions
All hardware exposed to seawater is titanium; the housing is plastic. No
corrosion precautions are required. The MicroTSG should be cleaned after use
and prior to storage, as described in Cleaning and Storage.
Cleaning and Storage
CAUTION:
The MicroTSG’s conductivity cell is
shipped dry to prevent freezing in
shipping.
MicroTSG with water in the
conductivity cell.Freezing
temperatures (for example, in Arctic
environments or during air shipment)
can break the cell if it is full of water.
CAUTION:
• Do not put a brush or any object
• Do not spray any solutions
If fouling remains in the conductivity
cell after these procedures, return the
MicroTSG to Sea-Bird for internal
cleaning and recalibration.
Do not store the

Clean the MicroTSG and conductivity cell:
• Monthly (during sustained use)
• Before periods of non-use – If the cell is not rinsed between usage, salt
crystals may form on the platinized electrode surfaces. When the
instrument is used next, sensor accuracy may be temporarily affected until
these crystals dissolve.
• If the data looks incorrect –
¾ Unusually noisy data may be caused by debris going through the cell.
¾ Unusually smooth data may be caused by a blockage in the flow path
or in the cell.
¾ Shifted data may be caused by fouling inside the cell.
Follow this cleaning procedure:
Step 1: Clean Out Drain
A. Keeping the MicroTSG in an upright position, remove the drain plug from
the housing’s bottom plate.
B. Allow any water to drain out and remove any sediment or debris from
the drain.
Step 2: Inspect and Clean Flushing Chamber
A. Remove the bottom plate:
i. Remove the six
washers securing the plate to the housing body. Hold the bottom plate
as you remove the hardware, to prevent the plate from falling.
ii. Pull the bottom plate straight down from the housing body, being
careful not to damage the conductivity cell, which sits in the housing.
B. Use a flashlight to inspect the flushing chamber and conductivity cell for
debris or fine deposits. If this is a routine monthly maintenance, and there
is no evidence of debris or fine deposits, proceed to Step 4: Clean Bottom Plate Assembly.
C. Gently spray fresh water up into the chamber to remove any fine deposits
inside the housing. Be careful not to hit the conductivity cell with the
spray hose.

Step 3: Flush Inside of Conductivity Cell
A. Remove the external plumbing connecting the seawater intake and drain
lines to the MicroTSG.
B. Clean the inside of the conductivity cell with a series of slow back flushes
into the OUT port (reverse of the normal operation flow). Collect the
drainage in a bucket held below the open housing:
•Refer to Application Note 2D: Instructions for Care and Cleaning
of Conductivity Cells for conductivity cell cleaning materials and
concentrations.
• The Active Use (after each cast) section of the application note is not
applicable to the MicroTSG.
C. If the MicroTSG is being stored, gently blow-dry the conductivity cell
and flushing chamber. Do not use compressed air, which typically
contains oil vapor.
D. Reinstall the external plumbing connecting the seawater intake and drain
lines to the MicroTSG.
Flush through anti-foulant device cup
O-ring
Note:
Early versions of the SBE 45 had a
rectangular o-ring in addition to the
round o-ring on the bottom plate; see
the photo in Replacing Anti-Foulant Device (SBE 45).
CAUTION:
• If you remove sensors and
electronics from the housing to
troubleshoot, avoid getting anything on the PCB, which can
be damaged by water or other
materials. See Appendix II:
Electronics Disassembly/
Reassembly.
• Do not put any object inside the
conductivity cell to clean it.
Return the MicroTSG to Sea-Bird
for internal cleaning and
recalibration.
Step 4: Clean Bottom Plate Assembly
A. Remove the O-ring on the bottom plate. Put the O-ring aside, being
careful to protect it from damage or contamination.
B. Flush the anti-foulant device cup on the bottom plate with fresh water, to
remove any debris or fine deposits. See Replacing Anti-Foulant Device
for details on touching or handling the AF24173 Anti-Foulant Device.
C. Rinse the bottom plate with fresh water.
D. Remove water from the O-ring and the bottom plate with a lint-free cloth
or tissue.
E. Inspect the O-ring and mating surfaces for dirt, nicks, and cuts. Clean as
necessary. Apply a light coat of O-ring lubricant (Parker Super O Lube) to
the O-ring and mating surfaces.
F. Replace the O-ring on the bottom plate.
Step 5: Reinstall Bottom Plate
A. Align the bottom plate with the housing body, ensuring the end of the
anti-foulant device cup is aligned with the conductivity cell. Slowly
position the bottom plate on the housing.
B. Re-secure the bottom plate to the housing body with the six
socket head screws, lock washers, and flat washers.
C. Reinstall the drain plug in the bottom plate.
If the data still looks incorrect after cleaning, it may be caused by:
• a problem with the electrical connections
• a problem with the PCB
• internal fouling in the conductivity cell that was not removed by flushing
• sensors that need to be recalibrated

Section 6: Routine Maintenance and Calibration SBE 45
Sensor Calibration
Sea-Bird sensors are calibrated by subjecting them to known physical
conditions and measuring the sensor responses. Coefficients are then
computed which may be used with appropriate algorithms to obtain
engineering units. The conductivity and temperature sensors on the MicroTSG
are supplied fully calibrated, with coefficients printed on their respective
Calibration Certificates (see back of manual). These coefficients have been
stored in the MicroTSG’s EEPROM.
Note:
Do not disassemble the MicroTSG
to send the sensors to Sea-Bird for
recalibration. Package the entire
MicroTSG for shipment, after
removing the AF24173 Anti-Foulant
Device (see Replacing Anti-Foulant Device). Store the AF24173 AntiFoulant Device for future use.
We recommend that MicroTSGs be returned to Sea-Bird for calibration.
Conductivity Sensor Calibration
The conductivity sensor incorporates a fixed precision resistor in parallel with
the cell. When the cell is dry and in air, the sensor’s electrical circuitry outputs
a frequency representative of the fixed resistor. This frequency is recorded on
the Calibration Certificate and should remain stable (within 1 Hz) over time.
The primary mechanism for calibration drift in conductivity sensors is the
fouling of the cell by chemical or biological deposits. Fouling changes the cell
geometry, resulting in a shift in cell constant.
Accordingly, the most important determinant of long-term sensor accuracy is
the cleanliness of the cell. We recommend that the conductivity sensors be
calibrated before and after deployment, but particularly when the cell has been
exposed to contamination by oil slicks or biological material.
Temperature Sensor Calibration
The primary source of temperature sensor calibration drift is the aging of the
thermistor element. Sensor drift will usually be a few thousandths of a degree
during the first year, and less in subsequent intervals. Sensor drift is not
substantially dependent upon the environmental conditions of use, and —
unlike platinum or copper elements — the thermistor is insensitive to shock.

Section 7: Troubleshooting
Note:
See the PN 90402 – SBE 45 Power,
Navigation, and Remote Temperature
Interface Box manual for additional
troubleshooting steps when
interfacing with the Box.
This section reviews common problems in operating the MicroTSG, and
provides the most common causes and solutions.
Problem 1: Unable to Communicate with MicroTSG
The S> prompt indicates that communications between the MicroTSG and
computer have been established. Before proceeding with troubleshooting,
attempt to establish communications again by clicking Connect on
SEATERM’s toolbar or hitting the Enter key several times.
Cause/Solution 1: The I/O cable connection may be loose. Check the cabling
between the MicroTSG and computer (or optional Interface Box) for a
loose connection.
Cause/Solution 2: The instrument type and/or its communication settings may
not have been entered correctly in SEATERM. Select the SBE 45 in the
Configure menu and verify the settings in the Configuration Options dialog
box. The settings should match those on the instrument Configuration Sheet.
Cause/Solution 3: The I/O cable may not be the correct one. Verify the cable
is the correct one.
Problem 2: Nonsense or Unreasonable Data
The symptom of this problem is data that contains nonsense values (for
example, 9999.999) or unreasonable values (for example, values that are
outside the expected range of the data).
Cause/Solution 1: A data file with nonsense values may be caused by
incorrect instrument configuration in the .xmlcon or .con file. Verify the
settings in the configuration file match your system.
Cause/Solution 2: Unreasonable values may be caused by incorrect calibration
coefficients programmed into the MicroTSG. Verify the coefficients match the
instrument Calibration Certificates, using DC.
Problem 3: Salinity Lower than Expected
Cause/Solution 1: A fouled conductivity cell will report lower than correct
salinity. Large errors in salinity indicate that the cell is extremely dirty, has
something large lodged in it, or is broken. Proceed as follows:
1. Clean the conductivity cell as described in Cleaning and Storage in
Section 6: Routine Maintenance and Calibration.
2. Remove larger droplets of water by blowing through the conductivity cell.
Do not use compressed air, which typically contains oil vapor.
3. Running the MicroTSG in air, use TSR to look at the raw conductivity
frequency. It should be within 1 Hz of the zero conductivity value printed
on the conductivity cell Calibration Sheet. If it is significantly different,
the cell is probably damaged.

Appendix I: Functional Description SBE 45
Appendix I: Functional Description
Sensors
The MicroTSG embodies the same sensor elements (3-electrode, 2-terminal,
borosilicate glass cell, and pressure-protected thermistor) previously employed
in Sea-Bird’s modular SBE 3 and SBE 4 sensors, in the SEACAT and
SEACAT plus family, and in the SBE 37 MicroCAT family.
Sensor Interface
Temperature is acquired by applying an AC excitation to a hermetically-sealed
VISHAY reference resistor and an ultra-stable aged thermistor with a drift rate
of less than 0.002 °C per year. A 24-bit A/D converter digitizes the outputs of
the reference resistor and thermistor. AC excitation and ratiometric
comparison using a common processing channel avoids errors caused by
parasitic thermocouples, offset voltages, leakage currents, and reference errors.
Conductivity is acquired using an ultra-precision Wein Bridge oscillator to
generate a frequency output in response to changes in conductivity. A high
stability TCXO reference crystal with a drift rate of less than 2 ppm/year is
used to count the frequency from the Wein Bridge oscillator.
Note:
Do not disassemble the MicroTSG
to send the sensors or PCB to
Sea-Bird for recalibration or repair.

Reassembly
Note:
Before delivery, a desiccant package
is placed in the electronic chamber,
and the chamber is filled with dry
Argon gas. These measures help
prevent condensation. To ensure
proper functioning:
1. Install a new desiccant bag each
time you open the housing. If a
new bag is not available, see
Application Note 71: Desiccant
Use and Regeneration (drying).
2. If possible, dry gas backfill each
time you open the housing. If you
cannot, wait at least 24 hours
before redeploying, to allow the

Deployment
1. Verify setting of Power-Up Jumper J1 (see product configuration sheet on manual front cover for factory-setting):
• Autopower (default) – pins 1 and 2. The MicroTSG wakes up when power is applied.
• Normal – pins 2 and 3. The MicroTSG power up (wakes up) when there is a pulse on the serial lines. In this configuration,
the MicroTSG can be commanded into a quiescent (sleep) state with the QS command.
If the factory-setting listed on the product configuration sheet does not match your desired operation, see the manual for
procedures for accessing the PCB.
2. Mount MicroTSG on ship, with electrical connector at top, using four
• Bottom — 152 mm (6 inches) clearance for removal of the bottom plate, to allow access for replacing the anti-foul cylinder
and cleaning.
• Top — 305 mm (12 inches) clearance for removal of the top plate, to allow access for removing sensors and electronics.
• Sides — small clearance by using washers with the mounting hardware, to prevent binding when removing the top or
bottom plate.
3. Install piping connections to MicroTSG’s
4. Wiring to MicroTSG:
A. Install I/O cable connector, aligning long pin with small hole on MicroTSG I/O connector.
B. Tighten locking sleeve on I/O cable connector.

Sampling Modes
User-selectable modes include:
• Polled sampling – The MicroTSG takes one sample and sends the data to the computer. Polled sampling is useful for testing.
• Autonomous sampling – The MicroTSG samples data at pre-programmed intervals, defined by the Interval= command, 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, take and output a single sample, and enter
quiescent (sleep) state automatically.

MicroTSG (Thermosalinograph)
The SBE 45 MicroTSG Thermosalinograph is an externally
powered, high-accuracy instrument, designed for shipboard
determination of sea surface (pumped-water) conductivity and
temperature. Salinity and sound velocity can also be computed. The
MicroTSG is constructed of plastic and titanium to ensure long life with
minimum maintenance.
OPERATION OVERVIEW
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 display and capture, and diagnostic tests. Userselectable 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 state automatically .
SBE 45
Calibration coefficients stored in EEPROM allow the MicroTSG to transmit data in engineering units.
SENSORS
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, and uses expendable
anti-foulant devices.

from navigation devices supporting NMEA 0183 protocol, outputting data in
GGA, GLL, RMA, RMC, or TRF format. Decoded Latitude, Longitude, date,
and time and SBE 38 temperature data are appended to the SBE 45 data stream
in the Interface Box. The data, in ASCII engineering units, is passed to the
computer for storage and/or display.
The Interface Box can be AC- or DC-powered:
• AC power - universal 85-265 VAC input with frequency of 47-63 Hz
• DC power - 10-28 VDC input.
The Interface Box is supplied with a powerful Win 2000/XP software package,
SEASOFT V2, which includes:
• SEATERM – terminal program for easy setup.
• Seasave V7 – program for acquiring, converting, and displaying real-time
or archived raw data.
•SBE Data Processing – program for calculation and plotting of
conductivity, temperature, pressure, auxiliary sensor data, and derived
variables such as salinity and sound velocity.
AC: 100-240 VAC / 47-63Hz / 0.25A,
The Interface Box should always be used with a threeterminal outlet that includes a protective earth.

Interface Box operates properly under the following
conditions:
Cables longer than 3 meters should be installed inside an earthed metal conduit
by a qualified electrician. This minimizes the potential for external signals to
disrupt communication and ensures that high voltage lines (such as the sea
cable) are sufficiently protected. Cables shorter than 3 meters can be used
without shielding when installing or bench testing the instrument.

When using Format=1:
• Set up the SBE 45 with:
¾ OutputFormat=0 or 1,
¾ OutputSV=Y, and
¾ OutputCond=Y and/or

Section 3: Setting Up System SBE 45 Interface Box
NMEA Navigation Device
The Interface Box is designed to decode messages that are output from
navigation devices supporting NMEA 0183 protocol, outputting messages in
GGA, GLL, RMA, RMC, or TRF format. Verify that the navigation device
baud rate matches the baud rate set in the Interface Box with NMEABaud=
(4800 or 9600).
Note:
Not all NMEA navigation devices
transmit time and / or date.
The most recent decoded Latitude, Longitude, time, and date data is appended
to the end of the SBE 45 data stream in the Interface Box and passed to the
computer for storage and/or display with the SBE 45 data. Position data format
is detailed in Appendix I: NMEA Data. The Yellow NMEA LED on the
Interface Box flashes each time a NMEA message is received (should be the
same rate at which your navigation device is transmitting).
Example 1: SBE 45 is set up to output data once every 10 seconds. A navigation device
outputs its NMEA message once every 5 seconds. The Yellow NMEA LED flashes
every 5 seconds. However, only the most recent NMEA message is appended to each
scan of SBE 45 data.
Example 2: SBE 45 is set up to output data once every 1 second. A navigation device
outputs its NMEA message once every 5 seconds, and the Yellow NMEA LED flashes
every 5 seconds. The same message is appended to each scan of SBE 45 data within
that 5 seconds.
While communicating with the Interface Box, send the ConnectNMEA
command to view the raw NMEA data.

files (in XML format). Versions 7.20a
and later allow you to open a .con or
.xmlcon file, and to save it to a .con
or .xmlcon file. Seasave and SBE
Data Processing use the same file.
• A new or recalibrated CTD ships
with a configuration file that reflects
the current configuration as we know it. The file is named with the
instrument serial number, followed
by a .con extension. For example,
for a CTD with serial number 2375,
Sea-Bird names the file 2375.con.
You may rename the file (but not the
extension) if desired; this will not
affect the results.
The Interface Box integrates optional NMEA navigation device data and
optional SBE 38 data into the SBE 45 data stream. Seasave, Sea-Bird’s realtime data acquisition and display program, stores and displays this data along
with the SBE 45 data. Seasave requires a configuration file, which defines the
SBE 45 – which parameters are output by the SBE 45, and the data output rate
- and indicates whether NMEA and SBE 38 data is to be appended to the data
stream. Seasave (as well as our data processing software) uses the information
in the configuration file to interpret and process the data. If the configuration
file does not match the actual instrument configuration, the software will
not be able to interpret and process the data correctly.
To verify the contents of the .xmlcon or .con configuration file:
1. Double click on Seasave.exe.
2. Click Configure Inputs. On the Instrument Configuration tab, click Open. In
the dialog box, select the .xmlcon or .con file and click Open.
3. The configuration information appears on the Instrument Configuration
tab. Verify that the outputs match those programmed into your SBE 45,
and that the use of the Interface Box, and addition of remote temperature
and NMEA, are correct. Click Modify to bring up a dialog box (shown
below) to change the configuration.

Section 4: Operating System
Note:
For acquiring data in Seasave:
• SBE 45 must be set up for
autonomous sampling
(SingleSample=N, AutoRun=Y,
and J1 jumper in Autopower position
– pins 1 and 2), and with
OutputFormat=0 or 1. See Section
3: Setting Up System.
• Interface Box must be set up with
Format=0 (standard format) and
IMode=NORMAL (Normal mode).
This section covers acquiring real-time data with Seasave and processing data
with SBE Data Processing.
• Seasave saves the data in the format (data format and header) required by
SBE Data Processing. If you use other software to acquire data, the data
will not be in the format required by SBE Data Processing.
See Connections, Switches, and LEDs in Section 2: Interface Box Description
for wiring details.
Acquiring Real-Time Data with Seasave
Notes:
• If the system includes an SBE 38
remote temperature sensor,
Seasave uses the remote
temperature data when calculating
density and sound velocity.
• The baud between the Interface Box
and computer (defined in Configure
Inputs, on the serial Ports tab) must
agree with the baud programmed
into the Box with PCBaud=.
1. Turn on power to the Interface Box. The SBE 45 will start sampling and
transmitting data to the Interface Box. Data will not appear in Seasave
until you tell Seasave to start real-time data acquisition below.
2. Double click on Seasave.exe.
3. Perform any desired setup in the Configure Inputs, Configure Outputs,
and Display menus.
4. In the Real-Time Data menu, select Start. The dialog box looks like this:

checks the configuration (.xmlcon or .con) file to verify that the scan
length defined by the configuration file matches the SBE 45 (i.e.,
number of outputs and inclusion of NMEA is as defined in the
configuration file). If a Scan length error appears, verify that:
• You are using the correct .xmlcon or .con file.
• The .xmlcon or .con file has been updated as necessary if you
added or deleted the SBE 38, added or deleted NMEA, etc.
C. Seasave sends a message: Waiting for data . . .. Seasave will time out if
data is not received within Timeout in seconds at startup.
D. Real-time data then starts appearing in the screen display(s).
6. To stop real-time data acquisition: In the Real-Time Data menu,
select Stop.
7. Stop the SBE 45 sampling by turning off power to the Interface Box.
83
Processing Data with SBE Data Processing
Note:
See the SBE Data Processing
manual and/or Help files.
1. Convert the .hex data file created by Seasave to a .cnv file in SBE Data
Processing’s Data Conversion module.
2. Once the data is converted, it can be further processed and plotted in
SBE Data Processing’s other modules. Note that if the data stream
includes SBE 38 remote temperature data, SBE Data Processing’s Data
Conversion and Derive modules use the remote temperature data when
calculating density and sound velocity.
1. Disconnect the power and any other cables from the Interface Box.
2. Using a soft cotton cloth dampened with warm water, clean the exterior of
the Interface Box with gentle pressure. Use special care cleaning around
any connectors, to avoid getting water into them.
3. Wait until the Interface Box is completely dry before reconnecting power
cables and other electrical connections.

Section 6: Troubleshooting SBE 45 Interface Box
Section 6: Troubleshooting
This section reviews common problems in operating the Interface Box, and
provides the most likely causes and solutions.
Problem 1: Unable to Communicate with Interface Box
The Interface Box message prompt indicates that communications between the
Interface Box and computer have been established. Before proceeding with
troubleshooting, attempt to establish communications again by clicking the
Connect button on SEATERM’s toolbar or hitting the Enter key several times.
Cause/Solution 1: The I/O cable connection may be loose. Check the cabling
between the Interface Box and computer for a loose connection.
Cause/Solution 2: The instrument type and/or its communication settings may
not have been entered correctly in SEATERM. Select SBE 45 in the Configure
menu and verify the settings in the Configuration Options dialog box. The
settings should match those on the instrument Configuration Sheet.
Cause/Solution 3: The I/O cable may not be the correct one. The I/O cable
supplied with the Interface Box permits connection to the DB-9P input
connectors used on standard RS-232 interfaces.
85
Problem 2: Unable to Communicate with SBE 45 through Interface Box
In SEATERM, while communicating with the Interface Box, send Connect45.
The following message should appear:
connected to SBE 45 . . .
This indicates that communications between the Interface Box and SBE 45
have been established. If this messages does not appear:
Cause/Solution 1: The cable connection may be loose. Check the cabling
between the SBE 45 and Interface Box for a loose connection.
Cause/Solution 2: The cable between the SBE 45 and Interface Box may not
be the correct one. Verify that the cable is the correct one.
Cause/Solution 3: The instrument type and/or its communication settings may
not have been entered correctly in SEATERM. Select SBE 45 in the Configure
menu and verify the settings in the Configuration Options dialog box. The
settings should match those on the instrument Configuration Sheet.
Cause/Solution 4: The baud rate for communication between the SBE 45 and
Interface Box may not match. The SBE 45’s baud rate (set with Baud= when
Note:
If applicable, see Problem 6:
Changing SBE 45 and/or SBE 38
Baud Rate without Cables for Direct
Connection below.
directly communicating with the SBE 45) must be the same as the baud rate
set in the Interface Box with 45Baud=.
Cause/Solution 5: The SBE 45 baud rate may be too high. The baud rate for
communication between the Interface Box and computer must be greater than
the baud rate between the Interface Box and SBE 45.
• Increase the Interface Box baud rate using PCBaud=. Or
• Connect the SBE 45 directly to the computer and decrease its baud rate
using Baud=. Then, with the Interface Box connected to the computer,
use 45Baud= to match the baud set in the SBE 45.

Section 6: Troubleshooting SBE 45 Interface Box
Problem 3: Unable to Communicate with SBE 38 through Interface Box
In SEATERM, while communicating with the Interface Box, send Connect38.
The following message should appear:
connected to SBE 38 . . .
This indicates that communications between the Interface Box and SBE 38
have been established. If this messages does not appear:
Cause/Solution 1: The cable connection may be loose. Check the cabling
between the SBE 38 and Interface Box for a loose connection.
Cause/Solution 2: The cable between the SBE 38 and Interface Box may not
be the correct one. Verify that the cable is the correct one.
Cause/Solution 3: The baud rate for communication between the SBE 38 and
Interface Box may not match. The SBE 38’s baud rate (set with Baud= when
Note:
If applicable, see Problem 6:
Changing SBE 45 and/or SBE 38
Baud Rate without Cables for Direct
Connection below.
directly communicating with the SBE 38) must be the same as the baud rate
set in the Interface Box with 38Baud=.
Cause/Solution 4: The SBE 38 baud rate may be too high. The baud rate for
communication between the Interface Box and computer must be greater than
the baud rate between the Interface Box and SBE 38.
• Increase the Interface Box baud rate using PCBaud=. Or
• Connect the SBE 38 directly to the computer and decrease its baud rate
using Baud=. Then, with the Interface Box connected to the computer,
use 38Baud= to match the baud set in the SBE 38.
Problem 4: Unable to Communicate with NMEA Navigation Device through
Interface Box
See Appendix I: NMEA Data for NMEA troubleshooting.
Problem 5: Nonsense or Unreasonable Data
The symptom of this problem is data that contains nonsense values (for
example, 9999.999) or unreasonable values (for example, values that are
outside the expected range of the data).
Cause/Solution 1: A data file with nonsense values may be caused by
incorrect instrument configuration in the .xmlcon or .con file. Verify the
settings in the configuration file match your system.
Cause/Solution 2: Unreasonable values may be caused by incorrect
calibration coefficients programmed into the instrument. Verify the calibration
coefficients in the SBE 45 and (optional) SBE 38 match the Calibration
Certificates. To verify calibration coefficients, use DC while communicating
with each instrument (either directly connected to the computer or through the
Interface Box) in SEATERM.
Cause/Solution 3: Unreasonable values may be caused by setting the
SBE 45’s output format to OutputFormat=2, which is incompatible with the
Interface Box. Verify that the SBE 45 is set to OutputFormat=0 or
OutputFormat=1 by sending DS while communicating with the SBE 45
(if the SBE 45 is set to OutputFormat=2, the last line of the DS response
shows conductivity and salinity order reversed).

Section 6: Troubleshooting SBE 45 Interface Box
Problem 6: Changing SBE 45 and/or SBE 38 Baud Rate without Cables for
Direct Connection
Note:
If you have a cable for direct
connection of the SBE 45 to the
computer and the SBE 38 to the
computer, see Setting Up
Instruments in Section 3: Setting Up
System to change the baud rates.
The baud rate for communication between the Interface Box and computer
must be greater than the baud rate between the Interface Box and SBE 45 and
baud rate between the Interface Box and the SBE 38. If you need to change the
baud rate in the SBE 45 and/or SBE 38 for compatibility with the Interface
Box, this procedure allows you to change the baud rate while the instrument is
communicating through the Interface Box. The procedure is written assuming
that the SBE 45 and SBE 38 are set to 9600 baud, but that you want the
computer to communicate with the Interface Box at 9600 baud.
In SEATERM:
1. Establish communications with the Interface Box, as described in Steps 1
through 4 in Communications Test and Setup in Section 3: Setting Up
System.
2. With the Interface Box in Normal mode, send PCBaud=19200
to change the baud rate between the Interface Box and the computer
to 19200.
3. In the Configure menu, select the SBE 45 and set the baud rate to 19200.
Turn power to the Interface Box off, and then on again. The Interface Box
is now communicating at 19200 baud.
4. To modify the SBE 45 baud rate:
A. Send 45Baud=9600 to set the baud rate in the Interface Box for
communication with the SBE 45 to 9600.
B. Send Connect45 to communicate with the SBE 45.
C. If the SBE 45 is sampling data, stop sampling by sending Stop (you
may need to send the command several times).
D. Send Baud=4800 to set the SBE 45 baud rate to 4800.
E. Type @ to return to Normal mode for communication with the
Interface Box.
F. Send 45Baud=4800 to set the baud rate in the Interface Box for
communication with the SBE 45 to 4800.
5. To modify the SBE 38 baud rate:
A. Send 38Baud=9600 to set the baud rate in the Interface Box for
communication with the SBE 38 to 9600.
B. Send Connect38 to communicate with the SBE 38.
C. If the SBE 38 is sampling data, stop sampling by sending Stop (you
may need to send the command several times).
D. Send Baud=4800 to set the SBE 38 baud rate to 4800.
Type @ to return to Normal mode for communication with the
E.
Interface Box.
F. Send 38Baud=4800 to set the baud rate in the Interface Box for
communication with the SBE 45 to 4800.
6. Send PCBaud=9600 to change the baud rate between the Interface Box
and the computer to 9600.
7. In the Configure menu, select the SBE 45 and set the baud rate to 9600.
Turn power to the Interface Box off, and then on again. The Interface Box
is now communicating with the computer at 9600 baud. If the SBE 45 and
SBE 38 are set up to begin sampling when power is applied, data will
appear.

Cause/Solution 1: Wiring may be incorrect. Check cables and connections
between the Interface Box, NMEA navigation device, and computer.
Cause/Solution 2: NMEA navigation device may be set to the wrong
communication parameters (Interface Box requires 4800 or 9600 baud, 8 data
bits, 1 stop bit, and no parity). Reset device’s communication parameters.
Verify that the baud rate in the Interface Box for communication with the
NMEA navigation device is set to match (NMEABaud=), and that the baud
rate is less than the baud rate for communication between the Interface Box
and the computer.
Cause/Solution 3: NMEA navigation device may not be transmitting data. See
the device manual for setup details. To verify that it is sending data, connect
an oscilloscope with ground on NMEA B (T17) and the probe on NMEA A
(T16). The signal should be less than 0.5 volts between messages and have
pulses greater than 4 volts for at least 0.2 milliseconds during the message.
Cause/Solution 4: Interface Box may not be operating properly. To verify, use
the simulation program supplied with SEASOFT V2. This program simulates
a NMEA navigation device transmitting a NMEA message. See NMEA Message Simulation Program for details.
Problem 2: Yellow NMEA LED Flashing, but Lat/Lon Data
Not Displaying
Cause/Solution 1: NMEA navigation device may be transmitting NMEA
messages in a format that cannot be interpreted by the Interface Box. To
verify, view the raw NMEA messages:
1. With the Interface Box running in Normal mode, type ConnectNMEA
and press the Enter key to switch to NMEA mode. The display looks
like this:
Decode NMEA messages, press @ or Esc to return to normal mode
2. The raw NMEA data should begin scrolling on the screen, followed by
See NMEA Raw Message Formats for a description of all the NMEA
messages the Interface Box can decode.
• If a different NMEA message is received than the Interface Box is
set up to decode, reconfigure your NMEA navigation device to
transmit GGA, GLL, RMA, RMC, or TRF.
•If no NMEA messages are received in NMEA mode, the problem
could be in the Interface Box, cable, or NMEA navigation device.
Verify that the Interface Box is operating properly using the
simulation program supplied with SEASOFT V2. This program
simulates a NMEA navigation device transmitting a NMEA message.
See NMEA Message Simulation Program for details.
3. Type @ to return to Normal mode.

Appendix I: NMEA Data SBE 45 Interface Box
NMEA Simulation Program
Sea-Bird provides a NMEA message simulation program, NMEATest, as a
troubleshooting aid. NMEATest, part of the SEASOFT V2 package, simulates
a NMEA navigation device transmitting NMEA messages. If the system does
not work with the NMEA navigation device, but works with NMEATest, the
problem is with the interface cable from the NMEA navigation device to the
Interface Box or in the NMEA navigation device itself.
NMEATest is just a simulation, and does not provide an actual data stream
from an actual NMEA navigation device. The data transmission baud rate
(4800 or 9600) and time between messages are user-programmable. The
NMEA message format (RMA, RMC, GLL, or GGA) generated by the
program is also user-programmable. Alternatively, the user can specify an
existing raw NMEA data file to use for the simulation; see NMEA Raw Message Formats for the required raw data format.
Note:
You can also run the simulation
using only one computer, if the
computer has a spare COM port.
Note:
The Interface Box must be
connected to the SBE 45 to test the
Box, because the Box only
transmits a scan of data when data
is received from the SBE 45.
To execute the simulation program, a second computer (computer 2) is
needed to emulate the NMEA navigation device. A laptop computer is
adequate for this purpose. Install NMEATest on computer 2 (NMEATest is
part of the SBE Data Processing installation).
Use the NMEA Interface test cable (PN 801422 - supplied with the Interface
Box) to connect the Interface Box to the simulation computer. The simulation
test cable connections are:
MS-3106A12S-3SDB-9SFunction
Pin A Pin 3 NMEA A (signal)
Pin B Pin 5 NMEA B (signal return)
Proceed as follows (instructions are written assuming you are using a second
computer to emulate the NMEA navigation device):
1. On computer 1, double click on Seaterm.exe.
2. Turn on power to the Interface Box. SEATERM displays:
SBE 45 Junction Box V 1.4
Data from the SBE 45 should begin scrolling on the screen.
3. On computer 2, double click on nmeatest.exe (in same directory as SBE
Data Processing). The NMEATest screen appears.
4. On the NMEATest screen, click on the Configure menu. The Configure
dialog box appears. Select:
• NMEA message to be simulated (RMA, RMC, GLL, or GGA) or
select an existing NMEA data file on your computer by clicking Send File and browsing to the desired file
• Baud rate (4800 or 9600) for transmission of simulated NMEA data
to Interface Box – must be less than baud rate between Interface Box and computer 1
• COMM port on computer 2 for transmission of NMEA data to
Interface Box
• Message interval (time between simulated messages to be transmitted
to Interface Box)
Click OK.

Appendix I: NMEA Data SBE 45 Interface Box
5. On the NMEATest screen, click Start. NMEA data should begin to display
on the NMEATest screen. Additionally, NMEA data should begin to
display appended to the SBE 45 data in SEATERM on computer 1. The
yellow NMEA LED should flash on the Interface Box each time the
simulation program transmits a new position. The appended data should
correspond to the most recent simulation program data. For example, if
NMEATest is set to output RMC data:
NMEATest output -
RMC: 2212.345,N, 04459.876,E, 15 May 2002 00:00:22
SEATERM output (appended after SBE 45 data and optional SBE 38 data) -
lat=22 12.345 N, lon=044 59.877 E, hms=000022, dmy=150502
See NMEA Raw Message Formats for the NMEA message formats.
If properly decoded data appears in SEATERM, the Interface Box is working
properly. If the system works with the simulation program but does not work
when connected to the actual NMEA navigation device, the problem is with
the cable from the NMEA navigation device to the Interface Box, or in the
NMEA navigation device itself.
• Verify that the cable pinouts are correct, especially at the NMEA
navigation device. See Connections, Switches, and LEDs in Section 2: Interface Box Description and also refer to the NMEA navigation device
documentation.
• If the cable is correct, verify that the NMEA navigation device is on and is
configured to send data. Many NMEA navigation devices have
programmable NMEA outputs and may need to be configured before they
will transmit NMEA messages. Refer to the NMEA navigation device
documentation, or contact the device’s manufacturer for customer support.
