Section 4 Overview
The SBE 39plus-IM is a high-accuracy temperature recorder. The sensor is designed for
moorings and other long-term, fixed-site deployments.
Optional equipment:
• Pressure sensor, strain gauge
• Fairing ("net fender") to protect from fishing lines and nets.
The SBE 39plus-IM is equipped with an internal battery pack and uses an Inductive
Modem (IM) to transmit data and get commands over a plastic-covered steel mooring
cable. The cable uses Differential-Phase-Shift-Keyed (DPSK) telemetry. No electrical
cables or connectors are required.
Two models are available:
• Embedded thermistor, with a time constant of approximately 25 seconds.
• External thermistor, with a time constant of approximately 0.5 seconds.
Communication with the SBE 39plus-IM requires an Inductive Modem Module (IMM) or
Surface Inductive Modem (SIM), for a serial interface between a PC or other controller
and up to 100 SBE 39plus-IM sensors. Communication is through a full-duplex RS232,
with commands and data transmitted half-duplex between the IMM or SIM and the SBE
39plus-IM.
The user can operate the sensor in one of several modes:
Autonomous operation—interval
• Operates at user-selected intervals (5–second to 6-hours).
• Operation sequence:
1. The sensor makes one measurement
2. The data is stored internally
3. The sensor goes into a low power mode until the next sample is collected.
Controlled (polled) operation
• Controlled data collection is useful when the sensor is integrated with satellite, radio,
or wire telemetry equipment.
• Operation sequence:
1. The sensor makes one measurement
2. The sensor sends the data to the controller
3. The sensor goes into a low power mode until the next command to operate.
Combo operation
The sensor operates autonomously and transmits the last stored data to the IMM or SIM.
Average operation
The sensor operates autonomously and transmits the average of the data collected since
the last transmission to the IMM or SIM.
4.1 Battery life
The battery pack is 4 size AA cells in series of 3 parallel strings. The battery holder has a
yellow cover plate. It is NOT compatible with the older battery holder that has a red cover
plate. The manufacturer recommends the user uses a conservative capacity value of
4.0 amp-hours, even though the nominal capacity is calculated at 5.2 amp-hours.
Battery life depends on the type of deployment, but in general, the limit is the memory
capacity, not the battery capacity. The 39plus-IM is shipped with the Deployment
Endurance Calculator software to calculate the maximum deployment time. Examples of
a manual calculations are shown below.
9

Example 1: Ten 39plus-IMs with pressure sensors are set up to take a sample every 5 seconds, or 720 samples/hour.
Sensors are set to full power transmit (SetEnableFullPwrTX=Y), with an average transmitted to a PC every hour. Setting is
#iiOutputFormat=1, approximately 80 characters per sample. How long can it be deployed?
Communications current draw = 0.84 mA-s/sample = 0.00084 A-s/sample.
720 × 0.00084 = 0.6048 A-s/hour
Transmit current draw/sample = 0.032 mA-s/character = 0.000032 A-s/character
0.000032 A × 80 characters = 0.00256 A-s/sample
In 1 hour, 1 × 0.00256 a-s/sample = 0.00256 A-s/hour
Standby current draw = 800 µA = 0.8 mA = 0.0008 A.
Current draw per query = 0.0008 A × 1 sec/IM × 9 other IMs on mooring = 0.0072 A-s/query
1 query/hour × 0.0072 A-s/query = 0.0072 A-sec/hour
Low power current draw = 60 µA = 0.06 mA = 0.00006 A
In one hour, 0.00006 A × (3600 seconds/hour - 720 × 0.28 sec/sample - 9 seconds standby) = 0.2034 A-s/hour
Power consumed/hour = 0.6048 + 0.00256 + 0.0072 + 0.2034 = 0.8180 A-s/hour
Battery capacity = (4.0 aH × 3600 seconds/hour) ÷ 0.0.8180 A-s/hour = 17603 hours = 733 days = 2.0 years
Number of samples = 17603 hours × 720 samples/hour = 12,674,000 samples
The memory capacity is approximately 5,500,00 samples. The 39plus-IM will continue to collect and transmit data
after the memory is full, but will not overwrite the data stored in memory.
Example 2: A 39plus-IM without pressure is deployed on a mooring set up to take a polled sample every minute, or
60 samples/hour. Sensor is set to full power transmit (SetEnableFullPwrTX=Y). Setting is #iiOutputFormat=1, approximately
80 characters per sample. The PwrOff command is sent immediately after each sample. How long can it be deployed?
Polled data collection current draw = 1.9 mA-sec/sample = 0.0019 A-s/sample. In 1 hour, 60 samples × 0.0019 A-s/sample =
0.1140 A-s/hour
Transmit current draw/sample = 0.032 mA-s/character = 0.000032 A-s/character
0.000032 A × 80 characters = 0.00256 A-s/sample
In 1 hour, 60 queries/hour × 0.00256 A-s/sample = 0.1536 A-s/hour
Standby current draw = 800 µA = 0.8 mA = 0.0008 A.
Current draw per query = 0.0008 A × 1 sec/IM = 0.0008 A-s/query
1 query/hour × 0.008 A-s/query = 0.0008 A-sec/hour
Low power current draw = 60 µA = 0.06 mA = 0.00006 A
***** one 39-IM or 9? see p. 14 of legacy manual.
In one hour, 0.00006 A × (3600 seconds/hour - 60 × 0.28 sec/sample) = 0.0595 A-s/hour
Power consumed/hour = 0.1140 + 0.1536 + 0.0008 + 0.0595 = 0.3279 A-s/hour
Battery capacity = (4.0 aH × 3600 seconds/hour) ÷ 0.3279 A-s/hour = xxx hours = xxx = xx years
Number of samples = xx hours × xx samples/hour = xxx samples
The memory capacity is approximately 5,500,00 samples. The 39plus-IM will continue to collect and transmit data
after the memory is full, but will not overwrite the data stored in memory.
Battery life is also affected by deployment orientation. The manufacturer recommends
that the 39plus is deployed vertically, with the thermistor pointed down, or horizontally. If
the 39plus is deployed with the thermistor pointed up, the battery life may be reduced by
up to 40%. This will not affect most deployments because even with a 40% reduction, the
SBE 39plus could still collect approximately 7.4 million samples, more than the memory
can store.
Overview

Section 5 Set up sensor and verify operation
Set up the hardware and install the software for the sensor to make sure that it functions
correctly before deployment.
• Install the manufacturer-supplied software.
• Verify operation.
IMPORTANT:all commands are pre-pended with #ii. Do not use #ii for RS232 and
SDI-12 protocols. For example, the "Stop" command is ii#Stop for IMM and SIM and
Stop for RS-232.
5.1 Inductive modems
An Inductive Modem Module (IMM) or Surface Inductive Modem (SIM) is required to
communicate with the SBE-39plus. The communication between the modem and
MicroCAT is half-duplex, and the modems operate at 1200 baud.
• IMM: available data rates are 1200, 2400, 4800, 9600, 19200, or 38400 baud.
• SIM: available data rates are 1200, 2400, 4800, or 9600 baud.
5.1.1 Set up IMM
Verify that the sensor and modem operate correctly before deployment. Operation notes:
• Supply the IMM with 7–24 V.
• The maximum current for operation is approximately 15 mA.
• The manufacturer recommends a minimum of 20 ohms impedance to reduce noise
during operational tests.
1. Make a loop of insulated test wire through the modem coupling and put the other end
of the loop through the IMM test coupler or ICC.
2. Connect the wire ends from the test coupler or ICC to J1 on the IMM.
3. Connect the IMM to the serial port of the PC.
4. Set up the IMM for either option A or B. Make sure to add a script that has one of
these setups to the buoy controller so the IMM can be re-set if it gets corrupted.

5. Send the GetCD command to verify that the IMM is set up correctly
5.1.2 Set up SIM
Verify that the sensor and modem operate correctly before deployment. Setup notes:
• Supply the SIM with 7–25 V.
• The maximum current for operation is approximately 30 mA.
• The manufacturer recommends a minimum of 20 ohms impedance to reduce noise
during operational tests.
Configure the SIM to operate in one of two modes:
Normal power (default)—the SIM operates when power is supplied. SIM setup:
• Connect "Power Common" to JP1 pin 1.
• Connect 7–25 VDC to JP1 pin 2.
• Verify there is no connection to JP1 pin 3.
• Verify the jumper is across J3.
Logic-level controlled power—this switches power to the SIM. SIM setup:
• Connect "Power Common" to JP1 pin 1.
• Connect 7–25 VDC to JP1 pin 2. If "VCNTL" is < 1 V, SIM is off. If "VCNTL" is > 2V,
SIM is on.
• Remove the jumper across J3.
1. Make a loop of insulated test wire through the modem coupling and connect the test
wire ends to the SIM cable terminals at JP4.
Set up sensor and verify operation
12

2. Remove the J5 jumper from the SIM.
This puts a 1K resistor in series with the inductive loop and reduces signal amplitude,
so that any other MicroCATS that are close to the connected sensor do not respond
to commands.
3. Connect the SIM to the serial port of the PC.
4. Interface connection: verify that the SIM is configured for RS232:
a. The jumper is on J1 pins 2 and 3.
b. The jumper is on J2 pins 2 and 3.
c. Remove the jumper on J4.
Set up sensor and verify operation
13

5. Connect wires to JP2:
a. Pin 2 is RS232 transmit from SIM to PC.
b. Pin 3 is RS232 transmit from PC to SIM.
c. Pin 5 is power common.
6. Inductive mooring cable:
• If the Inductive Cable Coupler (ICC) is installed, connect wires from the ICC to
JP4.
• If the ICC is not installed, connect wires from the mooring cable and seawater
ground to JP4 on SIM-direct.
Note that ICC v4 may have three wires. If the ICC has a pigtail termination, solder the
white and white-black wires together and attach to one terminal of JP4. Attach the
white-red wire to the other terminal.
7. For normal deployment, make sure that the jumper is installed on J5.
5.2 Install software and test sensor
Make sure that the sensor is connected to the PC through the serial connector on the
supplied cable. Most PCs no longer have serial ports, and a serial-to-USB adapter is
necessary. Make sure that the USB driver software is installed on the PC so that there is
communication between the sensor and the PC.
1. Install the Seasoft V2 software from the manufacturer-supplied CD.
2. Double-click on SeatermV2.exe to start the launcher. If this is the first time the
software is opened, a Serial Port Configuration window opens. The software
automatically connects at the default baud rate of 19200 but will try others if
necessary. The software automatically looks for the serial port number of the
connected sensor.
3. At the Instruments menu item, select SBE 39plus-IM.
4. Push OK to close this window.
The main window opens. The area on the left shows available commands. The large
area on the right shows commands and the responses from the sensor to those
commands.
5.2.1 Software menu items
Note that the sensor will "time out" if it does not receive a command for two minutes. To
start the sensor again, select Connect in the software Communications menu or push
Enter.
Set up sensor and verify operation
14

Menu item Description
File Load command file opens the selected .xml command file in the "Send Commands" area.
Unload command file closes the file and removes the commands from the "Send Commands" area.
Exit closes the program.
Communications Connect connects to the COM port. Disconnect disconnects from the COM port.
Configure establishes COM port and baud rates.
Disconnect and reconnect turns communications off then on. Useful if a sensor is non-responsive.
Command Abort stops the sensor. (The Esc key is equivalent.)
Send 5-second break is used with Serial Line Sync Mode.
Send stop command stops sensor operation.
Set local time/Set UTC time sets the clock in the sensor. (This is disabled if the baud rate is set at
115200 because the software cannot set the time at that rate.)
Capture Capture sensor responses to save real-time data or for diagnostics. Select Capture again to turn it off.
Capture status shows in the "Status" bar.
Upload Upload data from the sensor to a PC. Data is in an .xml format and is automatically converted to a .hex
and .xmlcon file for the Data Conversion software module.
Tools Diagnostics log saves diagnostic data.
Use Convert .xml data file to manually convert data if the automatic Upload does not convert the data.
Send script sends the same setup information to a number of MicroCAT sensors.
Options Select (default) or deselect the option to Prompt to launch data conversion after data upload.
5.3 Set up sensor ID and test IMM
1. From the Instrument menu, select SBE 39plus IM.
SeatermIM starts.
2. For IMM: after the first use, the software will send DS to automatically try to connect.
If there is no response to DS, the software continues to communicate with the IMM.
a. The software sends GetHD and GetCD to get the status of the IMM.
b. If ConfigType=1, the software sends PwrOn to all connected IMM sensors.
c. If ConfigType=2, the software sends ForceCaptureLine to reserve the IM line and
then sends SendWakeupTone to all connected IMM sensors.
d. The next try for connection depends on the ID configuration in the software from
the last time it was used.
• If the software is set to "Automatically get instrument ID" it sends id? and
waits for the sensor to communicate. The software then sends !iiGetHD and
#iiGetHD to the ID sent by the sensor.
• If the software is set to "Use fixed ID" it sends !iiGetHD and #iiGetCD to the
lD that was set the last time the user used the software.
e. The software shows the list of available commands in the Send Commands
window.
3. Do the steps below if the sensor does not respond to ID, !iiGetHD, #iiGetHD to
troubleshoot the problem.
a. In the Communications menu, select Configure. In the Configure
Communications window, select the COM port and baud rate for
communication. The manufacturer-set baud rate is on the Configuration page that
ships with the sensor.
If the ID is fixed, make sure that the ID is the correct one for that sensor.
b. Push OK.
c. In the Communications menu, select Connect.
Set up sensor and verify operation
15

• If Connect is not available, select Disconnect and reconnect. The software
will try to connect at the specified baud rate, but will try all other available
baud rates to try to connect.
d. If there is still no communication, check the cable and connections with the SIM
or IMM, the sensor, and the PC.
e. If there is still no communication, do step 1 with a different COM port or different
fixed ID and try to connect again.
4. In the software, enter #iiDS, then push Enter.

6. Each sensor on a mooring must have a unique ID so that it can communicate with the
IM and PC. Make sure that only one 39plus is online at a time to set the ID.
a. Enter *ID-ii to set the ID for the 39plus. (ii=user-assigned ID), then push Enter.
b. Enter the *ID=ii again, then push Enter to verify the information.
c. Record the ID.
d. Go to Communications menu, then Configure. Select Use fixed ID, then enter
the new ID and push OK.
The software now has the correct ID information to send commands.
7. Send additional commands as necessary.
8. Enter PwrOff, then push Enter to put the sensor in a low power mode.
The sensor is ready for application-specific setup and deployment.
5.4 Set up sensor ID and test SIM
1. From the Instrument menu, select SBE 39plus IM.
SeatermIM starts.
2. For SIM: after the first use, the software will send DS to automatically try to connect
to the SIM.
Set up sensor and verify operation

• If the software is set to "Automatically get instrument ID" it sends id? and waits
for the sensor to communicate. The software then sends !iiGetHD and #iiGetHD
to the ID sent by the sensor.
• If the software is set to "Use fixed ID" it sends !iiGetHD and #iiGetCD to the lD
that was set the last time the user used the software.
The software shows the list of available commands in the Send Commands window.
3. Do the steps below if the sensor does not respond to ID, !iiGetHD, #iiGetHD to
troubleshoot the problem.
a. In the Communications menu, select Configure. In the Configure
Communications window, select the COM port and baud rate for
communication. The manufacturer-set baud rate is on the Configuration page that
ships with the sensor.
If the ID is fixed, make sure that the ID is the correct one for that sensor.
b. Push OK.
c. In the Communications menu, select Connect.
• If Connect is not available, select Disconnect and reconnect. The software
will try to connect at the specified baud rate, but will try all other available
baud rates to try to connect.
d. If there is still no communication, check the cable and connections with the SIM
or IMM, the sensor, and the PC.
e. If there is still no communication, do step 1 with a different COM port or different
fixed ID and try to connect again.
4. In the software, enter #iiDS, then push Enter.
