P/N 950-6052-00 (February 2007) page 3

Figure 1. NEMO 42 Volt Configuration Wave Processing Module

System Overview The NEMO Wave Processing Module is used to process waves data from the ADCP and pro-vide a reduced data set suitable for local storage, and/or transmission to surface/shore via mo-dem, radio telemetry, or direct cable.

The NEMO unit requires a physical connection to the Workhorse ADCP and to an external de-vice (acoustic modem, inductive modem, or some other cable interface) to transmit data through that device to either a topside or shore-based platform. The device with which the Workhorse must interface does not always have the required bandwidth and throughput to han-dle the raw data stream. Therefore, the NEMO acts as a buffer interface and data pre-processor between the Workhorse and the I/O device. It communicates to the I/O device via a serial in-terface and controls the flow of data to/from the Workhorse.

• The NEMO has three serial ports: COM1 is connected to the ADCP, COM2 is not used, and COM3 is the port to the out side world. By default, the baud-rate between the Workhorse and the NEMO is 57600,8,n,1, and from the NEMO to the outside world is 9600,8,n,1.

• The NEMO software does not echo each character in command mode: that means the echo has to be turned on in BBTalk to see the characters when typing a com-mand. The latest release of BBTalk supports echo.

• To reduce power consumption, NEMO is design to go to sleep when it is not proc-essing data. This sleep period is controlled by the NEMO software. The Workhorse will buffer a complete wave-burst and then wake up NEMO and send the data.



• The NEMO can be woken up via a modem or PC on COM3 by sending a hardware break and then after waiting three seconds sending = = = to get the system in the command mode. NEMO needs three seconds to get all its hardware devices ready for receiving or sending data.

• In cable/shore powered applications NEMO can be configured to never go to sleep.

• NEMO supports RS-422 for shore powered applications.

NOTE. When using the command $awcm,getlatest, it is not necessary to put the NEMO Wave Processing Module in the command mode.

• The current ensembles that are collected while the Workhorse is collecting a waves-burst will be outputted to NEMO when the Workhorse is done collecting the wave-burst.

• The wave output message will have a time-stamp, when the Workhorse started to collect the wave-burst.

• NEMO will configure the Workhorse depending on its settings and then goes to sleep. NEMO can only process wave-bursts that are in packet mode.

• The first thing NEMO does when it is initially powered up is to look for the baud-rate of the Workhorse on COM1, and then NEMO will query the clock from the Workhorse and set its own clock.

• NEMO does not store the wave-burst data; the raw data will be stored on the Work-horse’s recorder. NEMO will save the processed wave/current data on it’s recorder card as well as sending it to the serial port.

• NEMO has a command-set that controls how many bins are going to be outputted to the serial output port in a current profile.

• After you send commands to the NEMO Wave Processing Module that configures it to start collecting data, the NEMO goes into deployment saver mode. If power is somehow removed and later restored, the NEMO simply picks up where it left off and continues to collect data using the same setup.

• The user can talk directly to the Workhorse via the NEMO Wave Processing Module (NEMO becomes transparent to the user). To do this, a software break needs to be sent to the Workhorse to get the Workhorse in command mode, this is done by send-ing ‘===’ to NEMO. Sending a hardware break to NEMO will not wake up the Workhorse, because this signal is used to wake up NEMO it self.

• After a deployment, the same data that was sent to the output serial-port can be found on the NEMO’s PC card on E:\RD Instruments\Project Files. NEMO does not have a command to delete these data files from the recorder card. The only way to remove these files after a deployment is to take the card out of NEMO and use a Laptop to delete the files.

Software Overview You will need BBTalk version 3.06 or higher to communicate with the NEMO. BBTalk is a terminal emulator that allows your computer to communicate with the NEMO via a serial port.

BBTalk Main Screen

Click the Help menu in BBTalk for information about how to use the program.

Communications Tips

• Since the NEMO Wave Processing Module does not echo characters back, you need to select the Echo Characters box on the BBTalk Options screen (see “Testing the NEMO,” page 19). Select NEMO in the BBTalk Connect To screen when you first open a connection will set this on automatically.

• If the NEMO Wave Processing Module is asleep it will not respond to any com-mands.

• Use BBTalk to wake the NEMO Wave Processing Module by sending a hardware break (press the End key) and wait at least three seconds before sending “===” or a command.

NOTE. The NEMO Wave Processing Module needs at least three seconds to wake up from the sleep mode.

NOTE. Under normal operation, the NEMO Wave Processing Module is always in the logging mode. The commands getlatest, dumpconfig, and reloadconfig are the only commands that the NEMO Wave Processing Module accepts without being in the command mode.


P/N 950-6052-00 (February 2007) page 11

Section 2.0: Preparation and Setup Proper preparation is critical for a successful deployment. In this section we will do a visual inspection to check for obvious damage, install the internal battery, and seal the NEMO for deployment.

Visual Inspection Before deploying the NEMO, make a quick visual inspection of the components to make sure nothing is damaged.

I/O Cable and Dummy Plug

Roll the rubber retaining-strap up so that it does not hinder dummy plug removal.

Remove the dummy plug by pulling with a straight-out motion. Do not wiggle the connector up; this can damage the con-nector. A slight side-to-side wiggle as you are pulling on the cable is OK.

Visual Inspection

Inspect the pins for damage. Make sure that they are straight and that there is no corrosion on the metal surfaces.

Inspect the NEMO housing and end caps for damage. There should be no missing hardware, cracks or peeling surfaces.



Battery Installation Before you use the NEMO, you must install the battery. To install the battery pack, do the fol-lowing steps.

NOTE. When the NEMO Wave Processing Module is shipped, the battery is installed but not connected. Open the unit and connect the battery cable.

Place the NEMO on its connector side end-cap.

Loosen and remove the four M6 bolts holding the battery side end-cap to the housing.

Gently slide the end-cap and battery assembly out of the housing.

Disconnect the battery cable from the connector.

Remove old Battery

Remove the rubber band, four wing nuts, lock washers, and washers holding the battery pack onto the posts.

Remove the support plate.

Slide the used battery pack off of the posts.

WING NUT (4)LOCK WASHER (4)FLAT WASHER (4)

Slide a new battery pack onto the four posts. Make sure the cable is not pinched by the battery pack.

Position the support plate over the four posts.

Place a flat washer, lock washer, and wing nut on each of the four posts. Tighten the wing nuts firmly to hold the battery in place.

Place a battery pack rubber band (two spare rubber bands are provided with each new battery) around all four wing nuts. This will prevent the wing nuts from backing off the post.

Use a large rubber band to hold the ca-bles in place.


P/N 950-6052-00 (February 2007) page 15

CAUTION. The battery pack is held in place by four sets of washers, lock washers, and wing nuts. If the wing nuts are not tight, the assembly of washers and wing nut can become loose and eventually fall onto the electronics. This could cause a short circuit. Place a rubber band around the wing nuts to help hold them in place.

Test the battery pack voltage by meas-uring across the battery connector. The voltage should be +42 VDC or higher for a new battery pack.

Connect the battery cable.

Seal for Deployment Before you put the NEMO into the water, you must seal it for deployment.

Clean the O-ring groove

Clean and inspect the O-ring grooves. Be sure the grooves are free of foreign matter, scratches, indentations, and pit-ting.

Thoroughly remove any old silicone lubricant.

Install a new O-ring

Lubricate the O-ring with a thin coat of silicone lubricant – just enough to make the O-ring “shiny”.

Apply the lubricant using latex gloves. Do not let loose fibers or lint stick to the O-ring. Fibers can provide a leakage path.

CAUTION. Check the O-ring groove thoroughly. Any foreign matter in the O-ring groove or a pinched O-ring will cause the NEMO module to flood.

CAUTION. Apply a very thin coat of silicone lube on the O-ring – just enough to make the O-ring “shiny”. Using too much silicone lube on the O-ring can be more harmful than using no O-ring lube at all.



Replace Desiccant

Desiccant bags are used to dehumidify the housing interior.

Remove the old desiccant bag.

Remove the new desiccant bags from the airtight aluminum bag.

Place a new desiccant pack and mois-ture indicator into the housing, next to the electronics.

Make sure no wires become pinched or that the O-ring falls out of the groove.

Install Hardware

Install all four sets of hardware until “finger-tight.”

Torque Bolts

Tighten the bolts in small increments in a “cross” pattern until the split washer flattens out, and then tighten each bolt ¼ turn more to compress the face seal O-ring evenly.

Tighten the bolts to the recommended torque value of 5.6 Newton-meters (50 pound-inches).

CAUTION. Do not replace the titanium hardware with any other hardware. Corrosion could cause the hardware to fail.

Connect the ADCP to the computer and use BBTalk to verify that the baud rate is set to 57600.

Once the ADCP baud rate is set, exit BBTalk and disconnect the ADCP from the computer.

Open the NEMO Wave Processing Module housing and disconnect the bat-tery cable.

Use the extension cable to connect the NEMO Wave Processing Module and the WorkHorse ADCP. Do so by push-ing straight in against the connector. Don’t wiggle the connector up; this will damage the connector.

NOTE: Place a light amount of silicone lubricant on the connector pins (rubber portion only). This will make it easier to connect or remove the cables and dummy plugs.

Remove the dummy plug and connect the I/O cable between the computer’s serial communication port and the NEMO Wave Processing Module.

NOTE. NEMO units are pre-configured to use RS-232 communications protocols. Your computer’s communication port must match the NEMO, or use an adapter.

Testing the NEMO Before deploying the NEMO, it is a good idea to make sure that it is working properly. This simple test checks that the NEMO is able to communicate with the computer and ADCP.

Start BBTalk

Start the BBTalk program (for help on using BBTalk, see the RDI Tools User's Guide).

On the Connect To screen, select NEMO. This ensures that the Echo Characters box is selected in the Options screen.

Select the COM port the NEMO cable is connected to.

Click Next.

Enter the Baud Rate, Parity, Stop Bits, and Flow Control. If you are unsure of the settings, leave them at the default settings.

Click Next.

Note: The Baud Rate must be 9600 to “talk” to the NEMO Wave Processing Module unit.

Verify the Echo Characters box is se-lected.

Click Finish.

Section 4.0: Troubleshooting the NEMO Use this section if you have a problem communicating with the NEMO Wave Processing Module or ADCP.

PC Card

USB Port


Remove the NEMO Wave Processing Module End Cap/electronics assembly.

Connect the NEMO Wave Processing Module to the ADCP and computer’s serial port.

Start BBTalk.

Disconnect the red/black power cable and then reconnect it in order to recycle the power.

The red LED should light and the NEMO Wave Processing Module should begin to configure the ADCP and start it ping-ing. This should take approximately one minute to complete.

Note: The USB Port is used to upload new NEMO Wave Processing Module software (see “Section 9.0: Upgrade NEMO Software,” page 44).

Fuse

If the ADCP or NEMO Wave Processing Module does not respond, check the NEMO Wave Processing Module cable connections, battery voltage, and fuse (located on the trigger board).

Check that the PCMCIA card is seated properly. If the card is not seated, the NEMO Wave Processing Module soft-ware will not start.

At startup of NEMO, you will see “junk” characters on the BBTalk screen; this is the WindowsCS startup.

The NEMO Software application will then start and automatically do the fol-lowing:

• Initialize the WorkHorse ADCP,

• Sync the clock with the ADCP’s clock,

• Start the deployment, and then

• Go to sleep.

Note: WindowsCS starts up with a de-fault baud-rate of 38400 and when the NEMO application starts it will change it to 9600 baud.


P/N 950-6052-00 (February 2007) page 25

Disconnect the I/O cable between the NEMO Wave Processing Module and the computer and connect the acoustic modem or other telemetry device.

Seal the NEMO Wave Processing Mod-ule housing (see “Seal for Deployment,” page 15).

Reconfigure the NEMO Wave Processing Module $awcm,load1200khz Entering Command Mode - Wave Sample ABORTED!! $awcm,savelast $awcm,reloadconfig Posting configuration to ADCP!! Sending CS Command and Exiting Command Mode!!

Retrieve Data from NEMO’s Recorder Card All the wave and current data Nemo sends to the serial port is also stored on Nemo’s recorder card. NEMO does not store the raw data from the Workhorse on its recorder card.

The only way to retrieve all the data from the NEMO’s recorder card is to take the card out of NEMO and install it in a laptop and copy the data to you hard-drive.

It is recommended to delete all the data files on NEMO’s recorder card before starting a new deployment. This must be done with a laptop/PC. The plain text files are located on the \RD Instruments\Project Files folder.

CAUTION. Do not edit or delete files in the \Program Files\RD Instruments\NEMO folder.

Section 10.0: Telemetry Options Use the following links for help with telemetry options.

Figure 11. Telemetry Options

Teledyne Benthos Subsea Acoustic Telemetry Modems www.benthos.com

Teledyne Benthos™ subsea acoustic modems serve as the underwater component of the bi-directional acoustic communication link. The subsea modems are interfaced with a host in-strument or AUV, and acoustically transmit/receive data from the host to the topside acoustic modem. Each subsea modem is available in a wide variety of configurations including cus-tomer selected frequency range and integral or remote transducer.

RDI recommends the ATM-885™/ATM-887™ model.

Seabird™ Underwater Inductive Modems http://www.seabird.com

The SBE 44 Underwater Inductive Modem™ (UIM) makes it possible to integrate current me-ters, Doppler profilers, or other instruments having standard serial interfaces with Micro-CATs™ or other instruments that communicate via Sea-Bird’s inductive modem telemetry sys-tem. The UIM has a built-in inductive cable coupler (split toroid) and cable clamp, providing data communications without the need for electrical connections, and an easy and secure at-tachment to any point on a jacketed mooring wire. An underwater bulkhead connector on the end cap provides the serial data connection, a control line, and switched power out.

RDI recommends the SBE 44 model.

NOTE. The SBE 44 has to have firmware version 1.7 or later and SBE 37 Surface Modem has to have firmware version 2.7 or later.

FreeWave™ Modems http://datataker.com/products/modem.html

FreeWave™ serial radio modems are long-range “set-and-forget” communication modules made by FreeWave Technologies, Inc. (USA). A pair of these modems can replace any RS232 connection with a transparent, error-free wireless link, making them ideal for remote data ac-quisition applications where cabling between the dataTaker and the computer is impractical, inconvenient or expensive. When used for remote data logging, each modem has two func-tions:

1. To receive radio messages from other modems and relay them to the device connected to its serial port (the host computer at the local end, or the dataTaker at the remote end);

2. To receive information from the device connected to its serial port (computer or data-Taker) and relay this, via its radio transmitter, to other modems.

RDI recommends the DT600™ model.

Sutron™ Data Logger/Transmitter http://www.sutron.com

Satlink Logger™ is Sutron’s newest multi-satellite data logger and transmitter designed to re-lay data through environmental satellites. Since 1975, Sutron Corporation has been the leader in design, manufacture, and support of satellite transmitters and data acquisition stations. Sat-link Logger builds upon Sutron’s vast experience of delivering over 30,000 field stations to customers around the world. Years from now, Sutron’s Satlink Logger will still be the Number 1 choice as the most reliable communications device available and will continue to dependably transmit data from thousands of meteorological and hydrological monitoring systems around the world.

Teledyne RD Instruments recommends the SatLink2 Logger/Transmitter SL2 G312-1 and -2 models.

Appendix – Shore Powered Real-Time Applications Cable Installation

The NEMO Wave Processing Module can also be used in a real-time application with shore power and communication. For this type of application, the NEMO should be set up for RS-422 (NEMO and shore), and powered with 50 VDC. Typically, NEMO would also be config-ured so it does not go to sleep. This means the Workhorse does not have to buffer a wave-burst before the NEMO Wave Processing Module processes it; it is simply receiving the data from the Workhorse as the data get collected. When the NEMO is configured to never go to sleep, NEMO will output a current profile as soon as the Workhorse has sent the data to it.

The NEMO Wave Processing Module has to be configured from the factory or the bench for this application. The command file on the Nemo’s recorder card command.txt needs to have following commands. cf11111 wa255 wc0 we5000 TX000000 CK

The value in the WakeIn tag has to be changed to 1 in the NGSP_CE_Setup.xml file in same folder. Disable output

For some telemetry applications it is useful to turn the NEMO Wave Processing Module output off and only retrieve data when the system gets queried.

To do this, the DisableAutoDataSerialOut tag has to be changed to 1 in the NGSP_CE_Setup.xml file.

CAUTION. Do not change other parameters unless you know what the option does.

Please contact Field Service if there is an issue setting the NEMO Wave Processing Module up for this application (see “Technical Support,” page 1).

Appendix - Example of a BBTalk Script File Script files are simply ASCII files produced by ASCII editors such as NotePad®. In general, they contain ASCII characters that are sent out through the serial port. In addition, BBTalk script files can contain embedded commands that control the behavior of BBTalk as it interprets the script file.

NOTE. For information on BBTalk script file commands, see the RDI Tools User’s Guide.

The script-file must have the extra blank line before the NEMO command. The $t (case sensi-tive) command in front of the NEMO command tells BBTalk that the line is not a BBTalk command. Lines that begin with a “;” are comments. BBTalk will ignore all comments. ;---------------------------------
