System Description
The Infrared Sea Surface Temperature Autonomous Radiometer (ISAR) (description on page 6) was developed
at Southampton Oceanographic Center and Brookhaven National Laboratory approximately ten years ago [Donlon
et al., 2008] for the purpose of providing data for satellite validation and for algorithm development.
This manual describes an installation for the JAMSTEC R/V MIRAI which includes a second-generation ISAR, interface electronics, and data collection software.
Note: details on the ISAR instrument are provided in the ISAR User Manual that was provided with the instrument.
The manual is available on line at http://www.rmrco.com/proj/isar6daq4/isarmanual.pdf.
Figure 1: The system block diagram.
• ISAR. The instrument that looks at the sea surface and measures the SSTskin from the emitted infrared radiation.
• PPT. A sensitive percipitation sensor that is used by ISAR to close its shutter in case of rain.
• GPS. A GPS sensor to record exact position as part of the data record. The ISAR also has a GPS position.
• REMOTE UNIT (RU). The electronic interface to the ISAR. The RU provides power control, ethernet connectivity, and serial connectivity to the different components.
• PC. A laptop running BASH Unix. Software in the PC collect and log raw data from the different devices.
Ten-minute statistics on SSTskin , position, rain, and ISAR status.
• AC Power. The system runs on external AC power, 100-240 VAC & 50–60 Hz. Current drain is < 2 amps.

General Description of ISAR
This section is one-page description of ISAR. See the ISAR manual for information on service and operation.
Infrared Sea Surface Skin Temperature Radiometer (ISAR)
The Infrared Sea Surface Skin Temperature Radiometer (ISAR) is designed to provide sea-surface skin
temperature (SSST) measurements in support of satellite calibration and validation activities. ISAR
will be deployed on volunteer ships in a global network and its operational goals are to make observations autonomously from a ship at sea for six-months
and with an accuracy of +/-0.1 C.
The tiny hole in the inner scan drum looks into a 45
degree mirror that reflects incoming infrared radiation into the infrared thermometer inside a waterproof housing, through a transparent window. The
scan drum can be pointed to the sea surface at a variety of angles, at the sky, and back into two highprecision black-body cavities. This cycle allows correction for sky contamination and the system is self
calibrating. A small amount of contamination can be
tolerated by this open air design.
ISAR incorporates a pitch-roll sensor, a flux-gate
compass, and a GPS and thus is completely selfcontained. A measurement cycle can be completed
as often as once per minute. The optical rain gauge
(shown on the upper left side of the instrument) is an
extremely sensitive detector of precipitation, and
when any droplets in the air are encountered, the
scan drum immediately rotates inward and the outer
door closes.
The outer panel is retracted and the
scan drum is rotated for viewing the
sea surface or sky.

The Data Acquisition System (DAQ)
Figure 2: The DAQ4 Remote Unit
(RU). The RU enclosure uses AC
power and an Ethernet connection
to the DAQ PC. Features include
AC line filter, AC power control
via the iBoot module, +15 & +24
volt DC power modules, DC power
control to ISAR via the Relay
module, and a five-port Serial-toEthernet hub (ISAR, Relay, GPS,
Spare tilt, open).
Figure 3: The DAQ4 User Interface
(UI). The UI for this installation is
simply a Mac Air 11” PC. Data collection software is written in Unix

GPS at the upper right. The power and Ethernet connections are available.
2.1
Installation Guidelines
• View to the sea surface. The ISAR must be able to view the undisturbed sea surface at an angle, from
downward, of approximately 15–55◦ . The view must be ahead of the ship wake. The most common view is
directly to port or starboard.
• AC Power. A stable AC power source (100-240 VAC, 50-60 Hz, > 2A). Research vessels usually provide a
UPS stable power for science and this should be used.
• Ethernet. An Ethernet connection to the UI PC is either a direct connection or via router into the ship LAN.
Note: Before beginning the installation a set of IP addresses are required. This can be either assigned by the
R/V network (best) or as a direct closed LAN. Table 1 is the set up for the MIRAI.

The laptop for the DAQ4 is an Apple Mac Air, 11". The computer software is written Unix with a BASH shell. The
software work well in a Linux (Ubuntu) operating system using a BASH shell.
Turn on the power switch. The computer boots the programs and ends as the screen below.
Figure 5:
The Unix terminal
screen (light yellow background
here) should be at the home folder.
Figure 6: The DAQ Mac OS X Dock.
The most important programs for general use are
(from left to right):
BBEdit: An excellent text editor with many features.
Terminal: Opens a new UNix terminal window.
Safari: Internet browser.
Zterm: A serial terminal for RS232 connections.
4.2
Sleepless Power Control
Normally the computer goes to sleep when the lid is closed or after a set time. Sleepless is a program that disables
the sleep action.
The upper right menu will look approximately like this:

Figure 7: The upper-right side of the task bar.
• Move the mouse pointer to the lightbulb on the left end of the menu above.
Figure 8: The Sleepless Menu.
The sleepless icon in the menu
bar as shown above has a red tag
when it is set properly.
• In the menu select “Prevent
sleep with lid closed, displays will
sleep” as shown.
4.3
Set the Ethernet addresses.
Refer to table 1 or one like it for the installation. Each of the devices must be set to the correct IP, mask, and router
if needed. The DAQ PC must be set to the PC address.
• Open Apple->System Preferences->Network.
• Set up a Location for the installation. (Check to be sure a proper Location has not been already set up.) The
IP assignment should be manual.
• Set the IP address, Mask, and Router if that has not been assigned.
4.4
Go to the DAQ Folder
Open a terminal window and enlarge it, by dragging the corner, to almost full screen size.
Jump to the DAQ software folder by entering the alias gtisar.

DAQ Setup File — su06.txt
The DAQ setup file full name is $HOME/ISAR/isardaq/setup/su06.txt
It contains information for data collection and computation of SSST.
Figure 9: Setup file.
The setup file controls almost all of the DAQ real-time operation and real-time data processing.
View the file with the Unix “less” program
~/ISAR/isardaq/$ less /setup/su06.txt
A typical setup file can be found in the Appendix. A setup record line has a “tag” followed by a
colon (:) followed by the datum for that line. Thus a line such as
SST INTERPOLATION CORRECTION: 1.0033
has a tag, “SST INTERPOLATION CORRECTION,” and the datum (1.0033). Exact line numbers
are not important. The software searches for the tag string.
Note: Software searches for the tag string only. Therefore there is no penalty for adding comment
lines in the file to help describe the data. The setup file shown in appendix C has many comment
lines and insertions.
5.1
5.1.1
Edit the DAQ Setup file
On BBEdit
BBEdit is a powerful text editing program. Most of the working files in the DAQ4 system are text
(ASCII) files and can be edited easily using BBEdit. To begin the editor simply double-click on
DAQ4—ISAR6 Manual— October 1, 2011
15
any menu item with the BBEdit icon. Any files of type text (.txt), hypertext (.html), perl (.pl), or
Expect (.ex) will open with the BBEdit text editor.
There are many text editors in the Unix system. “nano”, “vi”, and others can be used for simple
edits. However, we recommend highly that the operator here become familiar with BBEdit.
A complete manual, “BBEdit_10_User_Manual.pdf,” is provided for for reference. However, the
easiest way to learn the editor is just to use it.
5.1.2
edsu — Quick edit
Runs a program to make changes to the most important lines in the setup file.

6.5
ISAR Configuration File — isarconf.cfg
The ISAR configuration file is located in the software folder in the ISAR computer.
/home/isar/software/isarconf.cfg
This file contains information on the ISAR and ISAR operation. When the program boots up it
reads the config file.
Data lines in the configuration file are constructed like the lines in the DAQ setup file except an
equal sign (‘=’) is used instead of the colon as a separator. E.g.
START_DIAGN=0
is a typical line in the ISAR config file.
A copy of the configuration file is located on the DAQ PC as
$HOME/ISAR/isardaq/setup/cfg/isarconf_run.txt
6.5.1
Procedure to Change the Configuration file.
1. Copy isarconf.cfg to the DAQ PC. Do this if you are unsure if you have the current config
file in the DAQ PC.
Use fetch (section 6.3) to copy isarconf.cfg from ISAR to the PC. The name of the file on
the PC is isarconf_run.txt.
2. Edit isarconf on the DAQ PC. Use BBEdit or other editor.
Use BBEdit to edit isarconf_run.txt on the PC.
3. Copy isarconf_run.cfg to ISAR.
DAQ4—ISAR6 Manual— October 1, 2011
19
4. Replace isarconf.cfg with the new version.
cp isarconf_run.txt isarcong.cfg
5. Alternate: Edit isarconf.cfg directly in ISAR.
Edit the isarconf.cfg file directly in the ISAR. Make use of the text editor “vi” in Unix. Any
other available (in the ISAR OS) text editor (e.g. nano) will do.
As an example in this procedure we will edit the line tagged “ORG_MEAN_LIMIT=1.1” which
sets the threshold for the rain sensor to actuate the shutter.
This is an archive file. We will edit this then copy it to isarconf.cfg.
(a) vi isarconf_run.txt
(b) Find the line ORG_MEAN_LIMIT=1.1
(c) Change to ORG_MEAN_LIMIT=1.5
(d) Move the cursor to 1.1
(e) ’R’ and enter 1.5<esc>
(f) Save and exit: :wq<return>

"START" command. When the START command is entered the following folder is created
Definition of a “Data Set”.
ISAR/data/data_20110617T194516Z
When the STARTCAL command is entered a calibration data set is created

Calibration
Calibration System Description
CASOTS 4000l/hr (67l/min = 16 gpm) with 24 VAC 50 Hz. 50 Hz is important. A transformer to
convert 100 VAC to 24 VAC
Probe Thermometrics #225 Hart #1504
Tweener Readout 1504 Tweener Thermistor Readout If you need more accuracy in a limited
temperature range, the Model 1504 Tweener gives it to you as a thermistor readout. Thermistors
are less fragile than PRTs and less likely to be impacted by mechanical shock. Thermistors are
more sensitive to temperature, have faster response times, and come in many shapes for different
applications.
Typical accuracy of a 1504 is ś0.002 C with a resolution of 0.0001 C.

4. Connect the ISAR test cable. Make sure all connections to the cal system are correct.
5. Turn on AC power to the calibration system. Check the lights on the switch, hub to be sure
power is on to all devices.
6. Connect the Mac Air (or a calibration PC if different) ethernet connection to the network
switch on the calibration circuit.
7. Ping the calibration hub with the PingCalHub command. The ping must be successful.
8. Connect to the ISAR with the Ic command. The ISAR data lines should be correct. Note:
For the calibration the ISAR view angles are 325, 280, 25, and 90 degrees.
9. Turn on the Hart temperature readout. Check that the probe is inserted into the bath properly.
Check that the temperature readout is degC.
10. Check the temperature probe with the B terminal command. The readout should produce
temperature records each 2 seconds.
Begin the Calibration.
11. Add ice to the bath water to cool the bath to at least 10 degC.
12. Use the B terminal command and check the start temperature is low enough. End the
connection with <control>-\ followed by Q;
13. If everything checks out enter STARTCAL to setup the calibration data folder (datacal...).
14. Begin data collection with the terminal command Gc.
Ending the Calibration.
15. End the calibration when the water temperature exceeds 35 degC. Enter <control>-C to
terminate the data collection.

Steps to Setup a New PC
User files install the latest user files. These can be obtained from RMR Co. It is suggested that these be provided directly
from RMR Co. by email/ftp data transfer.
Xcode Tools The programmer’s package “Xcode Tools” must be downloaded from the Apple Xcode Web site. It costs a
small amount for the package (≈$10). The download file is very large (approx 800 MB) so allow plenty of time
for the transfer.
Xcode installer After the Xcode Tools package is installed, and this could take a few hours, you must run the installer package.
Go to the Applications folder and double-click the “Install Xcode” application.
Reboot At this time reboot the computer so the Xcode package is loaded into the operating system.
MacPorts The MacPorts package is a method for downloading and installing software packages, ‘ports’, automatically
and easily. Go to the MacPorts download page and follow the instructions. A good user guide is available on
line.
• Check the install is successful by entering “port and the reply should look like “MacPorts 1.9.2” followed by
a prompt. Enter “quit” to end the port application.
Terminal Configure the Terminal (Unix shell) application.
• Run the Terminal window. In preferences, under the “Window” tab, set “Window Size” to Columns=155 and
Rows=32. Number of rows set to 10000.
• Under the “Shell” tab, Startup:Run Command field is blank.
• All other settings such as color or keyboard settings can remain default.
• From a terminal window use the “nano” application to edit the file named “~/.profile” so the last line containes the command “bash”.
Kermit Install the Kermit software. A good site for this is via the MacUpdate site.
• Download the Kermit package, kermit80212, and place it in the ~\sw\ folder.
• cd to the kermit folder and run “make macosx”.
• Next run the command “cp wermit /usr/bin/kermit” to place the program in the correct location.
• Using ‘nano’ or other text editor create a file ~\.kermrc in the home directory with the line “prompt k>>”.
• Check the install by entering “kermit” in a terminal window. You should see a prompt, “k>>”. Enter “version”
and the reply should include a line with something like
“C-Kermit 8.0.212 Dev.26, 20 Dec 2006, for Mac OS X 10.5.7”.
• Quit kermit with the “quit” command.
TeXShop The TeXShop package is useful for upgrading documentation.
• TeXShop can be downloaded and installed from TexShop Home Page.
DAQ4—ISAR6 Manual— October 1, 2011
36
• Additional packages are needed. Create a folder in the Unix home directory (“cd ~/”) called “~/tex/”
• Copy the RMR Co. folders texstyles and texinput into this folder. These are available from RMR Co..
R The statistics and plotting package called “R” is used in some presentation and processing software.
The program can be downloaded from the R Homepage.
Tcl Install the Tcl/Tk package.
• Use the MacPorts to install the current version.
From the Terminal window enter “sudo port install tchsh8.5”
• Check the install by entering “tclsh” and you should see the prompt “\%”. Enter “^C” to quit.
Sharing Certain system sharing packages must be configured. From under the Apple symbol opne “System Preferences” and then, under “Internet & Wireless” open the “Sharing” folder.
• Set the Computer Name to “isar6”.
• Turn “Screen Sharing” on.
• Under Screen Sharing go to “Computer Settings...”, select “VNC viewers may control screen with password:”,
and set the password to “isar06”.
• Also set “Allow access for:” to “All users.”
• Next, under “Sharing,” turn “Remote Login” on and “Allow access for:” set to “All users.”
Zterm Install the open source Mac terminal program Zterm.
• We use the UC232A USB to RS232 driver. This is a popular and common piece of essential hardware.
• The UC232A requires a driver which can be found on line. The driver comes as a ‘.rar’ file and requires a rar
converter. Download the application UnRarX online.

Miscellaneous Problems and Procedures
Shutter Gear Runs Off the End of the Belt
There is a gap between the shutter belt and the rubber stopper. Sometimes, by accident, the shutter is run too far
and the gear moves into the gap. Then the gear spins.
Solution. When the gear is turning, move the shutter by hand so it engages the belt. Actually this should not
happen in normal operation. In test mode it is possible to run the motor until this occurs.

Glossary
ASCII
CASOTS
The American Standard Code for Information Interchange is a character-encoding scheme based on the
ordering of the English alphabet. The same as a ‘text’ file.
The portable water bath calibration system developed by SOES.
CLIENT/SERVER
Client/server describes the relationship between two computer programs in which one program, the client,
makes a service request from another program, the server, which fulfills the request. Although the
client/server idea can be used by programs within a single computer, it is a more important idea in a network.
DAQ4
The data acquisition hardware and software developed by RMR Co. to support installation of ISAR6 and
provide computed SSST to local data collection.
DIN
DIN is an acronym for Deutsche Institute fuer Normung, a German standardization body and member of the
International Standards Organization (ISO). DIN rails and mounting hardware are standard mounting equipment for a variety of electronic components, including terminal blocks to connect wiring. DIN rails and DIN
mounting hardware are internationally approved, industry standard hardware for a vast array of components
made by computer manufacturers. DIN rail terminal blocks also offer grounding and disconnecting capability
and provide self-locking clamps to ensure a tight connection.
DIN Rail
A DIN rail is a metal rail of a standard type widely used for mounting circuit breakers and industrial control
equipment inside equipment racks. The term applies to multiple similar standards.
EXPECT
Expect is a Unix automation and testing tool, written by Don Libes as an extension to the Tcl scripting
language, for interactive applications such as telnet, ftp, passwd, fsck, rlogin, tip, ssh, and others. It uses Unix
pseudo terminals to wrap up subprocesses transparently, allowing the automation of arbitrary applications
that are accessed over a terminal.
HUB
A HUB in the DAQ is a device that concentrates several serial communication lines (RS232, RS422, RS485)
into a single Ethernet IP port.
ISAR
Infrared Seasurface Temperature Autonomous Radiometer (ISAR)
ISAR6
The particular ISAR system introduced after ISAR SN# 6.
KERMIT
Kermit software offers interactive and scripted file transfer and management, terminal emulation, Unicodeaware character-set conversion, and/or Internet security
MATLAB
Matlab is a numerical computing environment and fourth-generation programming language. Developed by
MathWorks, MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages, including C,
C++, and Fortran.
MODEM
The “modem” is an interface to the Iridium SBD data system. The DAQ4 has all connectors and software to
add the NAL 9602 modem.
NIST
The National Institute of Standards and Technology (NIST), known between 1901 and 1988 as the National
Bureau of Standards (NBS), is a measurement standards laboratory which is a non-regulatory agency of the
United States Department of Commerce.
PERL
Perl is a high-level, general-purpose, interpreted, dynamic programming language. Since it was developed
in the mid-eightys, it has undergone many changes and revisions and become widely popular amongst
programmers. The language provides powerful text processing facilities without the arbitrary data length
limits of many contemporary Unix tools, facilitating easy manipulation of text files.
RU
The RU is the remote Unit of the DAQ4. It is located in an unsheltered area close to the ISAR and provides
an interface between the ISAR and the User Interface (UI).
SBD
SETUP FILE
SOES
Southampton Ocean and Environment School. The company that makes the ISAR.
SSST
Sea surface skin temperature. The temperature of the, approximately, 10µm of the ocean surface.
SWITCH
UI
A network switch or switching hub is a computer networking device that connects network segments.
The User Interface (UI) is the part of the DAQ4 that controls the RU, collects and processes data, and
computes SSST for the data system.
