Olex 8.1 - new and improved functions for serial port handling and diagnostics.

Olex 8.1 introduces a much more powerful serial port management. In classical Olex, the serial ports were statically named in the file serieporter, and one could see all traffic combined together on the data traffic window. If one desired to disable some incoming NMEA, one had to enter Linux and modify the file glemnmea using a certain syntax. Locking ports to specified baud rates likewise involved editing serieporter. Adding or removing serial ports meant yet more Linux commands.

The new Olex version is still compatible with this old way. But it now probes for serial ports upon every bootup. To add ports, first power down the system; do the necessary hardware change; reboot. Any new ports found is automatically enabled for Olex use. The serieporter file is still consulted for special options, but is not really required anymore.

This shows the new and improved data flow window. There are a number of buttons per serial port:

Show - pressing this makes the data flow window list only the sentences coming from this serial port. If none ports have the Show button pressed, the system reverts to the old style of showing everything mixed together.

Auto - this enable the automatic baud rate detector. It is on by default, but can be turned off to lock a certain baud rate.

Shift - when Auto is not pressed, this button let you chose a different baud rate.

The green blob flashes for every sentence received on that port.

There is also a button for every sentence or message type observed. Pressing one such button disables the message in question. Messages observed in the past but not present anymore, are shown in grey.

At the bottom of the window, there are new buttons to only show faulty messages, and to log some data to a file. When the logging is turned off, the system calls up the file browser so that you can store the log file to some external media.

Log files can be used to make new demo files. When storing a log file, give it a name that starts with "demologg." - for example demologg.mydemo. Copying such a file to an Olex demo machine includes the file in the demo loop.

Here we inspect one port in particular. We note how the DBT and DPT sentences are disabled, letting only MTW come throgh.

In this example, the Olex has detected a sentence that appears from muliple serial ports. In the past, such a conflict was resolved through the glemnmea file, which is still honored for backwards compatibility. But now, the conflict is resolved by simply clicking on the one you want to suppress. As long as the conflict is left active, both buttons are flashing. The Layers button on the top menu, as well as the Data flow window button on the Layers menu, would also flash to remind you that you need to investigate.

This example is from a different Olex, with a builtin GPS not seeing the sky. The VTG sentence is disabled by the user. The data flow window shows a mixture of sentences; some in black, some in grey, some in red. The grey ones are either unrecognized or disabled messages, while those in red have checkum or format errors. If "Show only faulty messages" had been pressed, only the red ones would show.

August 2011


The aquaculture exhibition, AquaNor 2011 were held in Trondheim in August. According to tradition, Olex AS used the opportunity to meet our customers and associates, from our own exhibition stand, with information and news about our products. In addition to our own Olex mapping system we had for display a Wassp multibeam sonar, Valeport sound speed probe and our new GP9200, 3D GPS for exact positioning and absolute height.

Aqua Nor, had a record number of visitors this year. According to the organizers more than 17,500 visitors from 61 nations participated. This equals a 25% increase compared to the last exhibition two years ago. During four hectic, but enjoyable and interesting, days the Olex stand were visited by a large number of, old and new, customers and friends from all over the world.

New Olex technology now allows WASSP and Olex to map the water column as well as the seafloor.

Fish and other objects, like ropes and cables, are detected by the Wassp multibeam sonar, mapped by Olex and immediately shown in 2D and 3D. By pointing at the map the Olex user can see the exact position of the fish and objects. The new function are available in version 7.14.

Olex distributes multi-beam echosounder!

Olex AS is pleased to announce the expansion of its product portfolio to include WASSP, a multi-beam echosounder from the New Zealand based manufacturer ENL. Olex AS has enhanced the interoperability of its existing multi-beam software to interface with WASSP, and is now offering a complete multi-beam survey package for its customers in Norway. Customers outside Norway can purchase the Olex multi-beam system only, and can be interfaced with your locally acquired Wassp.

The WASSP system is a multi-beam fishing system that uses a wide-angle sonar to profile the water column and seafloor at a very high resolution. It provides a wide 120° port-to-starboard swath of the water column and seafloor, allowing users to find and map the seafloor, reefs and wrecks, seafloor hardness, and foreign objects in the water column. From the 120° swath, the system receives 112 dynamic beams, with each beam containing data from the water column and seafloor.

This high-tech multi-beam echosounder is now commercially available for fishing vessels, survey companies, fish farmers, diving companies and others who are interested in fishing and seafloor mapping.


Olex appoints two new distributors

Olex AS proudly announces the appointment of two new distributors to its world wide Olex distribution network; Selmar Ltda of Chile and Norwegian Partners Marine (NPM) of Russia.

The Selmar main office is based in Talcahuano, but has sales and service offices in several of the most important Chilean fishing ports. Selmar Ltda is one of the most significant distributors of marine electronics in the country, and is the second distributor of Olex established in South America.

Norwegian Partners Marine (NPM) has a total of 8 branches in different locations throughout Russia, employing engineers and other professionals in the fields of sales, engineering, installation and service. NPM has already proven to be an efficient and skilled distributor of Olex products.


Olex introduces automatic water current detection and mapping

We have now introduced a new Olex software module called SB. This module lets the Olex detect and map water currents. By analyzing five NMEA data types - position, speed over ground, course over ground, true heading, and speed through water - the vessel drift related to ground is calculated and shown as a variable-size arrow pointing away from the ship. This drift is assumed to be representative of the water current. Accuracy is very good and only limited by instrument resolution.

In addition to the realtime water current, the values are also mapped in a cell-like structure much like the seabed depth, albeit at a somewhat coarser resolution. The mapping takes the main tidal phase into account; that is, for a given position, currents are mapped in several time slices synced to the moon's angle from the earth, the so-called M2 tidal constituent.

The effect of this is that as the vessel sails around and collects current readings, a detailed map of water flow is built up; at any time, the assumed currents are shown as small arrows, related to the actual point of the tidal phase. There is a slider available to test how the flow will be like at a certain time into the future.

The latest Olex version, 6.4, contains a demo and sample data collected by our own vessel a few months ago. The attached screenshots are from the demo. Future versions will allow sharing of currents data.

Mapped water current

Calibration screen


One can use surprisingly simple instruments for this current mapping. This is possible because Olex does a good job in calibrating the sensors, recognizing various short-term errors, and using GPS positions for prediction validation.

In our own boat, we use a Furuno SC-60 for position, heading, course and speed over ground, and a simple paddlewheel water speed sensor from Airmar for speed through water. These two instruments are sufficient. Of course, a higher grade water speed sensor can also be used, but careful sensor placement and high grade true heading may be more important. Maybe a mid price electromagnetic solid state sensor will be a good option.

At the Nor-Fishing expo, we were approached by skippers having costly doppler sonars capable of giving water currents at various depths. A natural development will be to interface to such instruments, to map currents close to the sea bottom.


Regardless of what water speed sensor is used, it has to be calibrated for nonlinear speed response due to water flow patterns. The Olex has a special mode where it asks the skipper to steer opposing straight lines at various speeds, automatically working out a graph of apparent water speed and correction factors. Same for the heading sensor. This procedure will likely only be done during initial water trials, but can be repeated by the skipper if deemed necessary.


This new SB module has a list price of one-third the normal Olex price - 10.000 NOK, EUR1300, USD1660, GPB840, CAN1960 - the same as the ITI software module. The software is part of Olex 6.4, available for download now from our web site.

Olex appoints SELEX Communications as distributor

Norwegian based Olex AS, the manufacturer of complete systems for navigation, plotting and 3D seafloor mapping, is pleased to announce the expansion of its UK and Ireland distribution network with the appointment of a new distributor, SELEX Communications.

With more than 2,000 installations worldwide, including more than 350 in the UK and Ireland, the Olex systems are proving extremely popular onboard all types and sizes of fishing vessels. SELEX Communications will distribute the Olex systems through its 18 Regional Offices and through more than 30 independent dealers in the UK and Ireland.

After years of research, development and testing, Olex AS has developed the most comprehensive seafloor topography mapping system available on the market, with sales of Olex Systems for navigation and seafloor mapping worldwide increasing rapidly.

As Olex AS continues to grow, it is aware of the importance of choosing distributors that can provide the best possible support to its dealers and customers. With the largest staff of Marine Electronics Engineers in the UK and with more than 100 years of marine electronics experience SELEX Communications has the capacity to handle the growing demand for Olex technology.

"SELEX Communications, will help us to secure an excellent nationwide sales and support network, in conjunction with Aberdeen based distributor Woodsons of Aberdeen," says Ole Jorgen Orsnes, Export Manager for Olex AS. "SELEX Communications will distribute Olex systems across the UK and Ireland, with Woodsons of Aberdeen continuing to concentrate on distributing the Olex Systems in Scotland and Ireland."

Earlier this month Olex technical staff conducted a training workshop with engineers from SELEX Communications at the company's Head Office in Chelmsford. This training covered all aspects of the Olex Systems and SELEX Communications are in the process of introducing themselves as Olex distributors to dealers and customers across the UK and Ireland.

"In order to make the Olex Systems even more accessible, SELEX Communications will make just the chart software available, rather than packaging it as a complete system including hardware. This more flexible approach will allow our dealers and customers to easily order new hardware and charts without any delay," says David Evans, Vice President - Marine for SELEX Communications.

The Olex Systems are based on Linux, and are considered to be the most stable systems of their kind available on the commercial market. Speed, flexibility and user-friendly are important keywords to explain the success of the Olex Systems.

Press release 09/30/2005

Olex 3D technology maps the sea floor and skippers all over the world are joining the movement!

Olex AS has collected sea floor data from Olex users all over the world since 1998. The Olex sea floor database consists of soundings from the simplest single beam echosounder to the more technically advanced and very precise multibeam echosounders. The Olex users willing to share their data now have access to over 70 billion ocean depths compressed into 20 CDs for easy loading to the Olex system. This is the most comprehensive sea floor database of its kind, and is available to all Olex users, free of charge.

The Olex Sea Floor Map

Compared to anything else available in the commercial market, the Olex sea floor map offers an amazingly detailed view of the ocean topography. This is made possible by using the most technically advanced software available, in combination with data from echosounders and GPS: You connect both a GPS and an echosounder to your PC or laptop with the Olex preinstalled software. Olex records the different pings from the echosounder in combination with the GPS data given for that specific position. The Olex system calculates the sea floor topography in between the recorded depths, so that you do not have to measure each and every square meter of the sea floor. This calculation takes into account the tide level and various instrument offsets.

All of this is done fully automatically, and you can follow the sea floor mapping in real-time on the screen in both 2D and 3D.

The Olex users have seen the benefit of sharing their sea floor data with each other and/or with Olex AS. Submitting their data to Olex AS gives the users access to both their own quality-checked sea floor data, and all available data in the shared Olex database. Both the quality-check of the sea floor data and the data sharing is free of charge. The Olex sea floor database is rapidly growing and holds over 70 billion measured and calculated sea floor depths. This data is compressed into 20 CDs that can easily be used with any Olex system. By providing access to incredibly accurate sea floor details in a realistic 3D view, the Olex sea floor information will not only help increase fishing yields, but also make navigation safer.

“One of the many challenges handling this vast amount of data using real-time, is speed”, says Olex’s Export Manager Ole Jørgen Ørsnes. “There is no advantage in having seabed mapping in 3D if you have to wait up to 30 seconds for the picture to draw, and then another 30 seconds if you want a new picture. The biggest advantages of the Olex 3D system are high speed, simplicity of use, and the detailed and very realistic sea floor view”, he says.

When you are at sea, the Olex system is able to automatically recall all stored data. Most Olex clients perceive Olex as a marine instrument rather than a computer based software, since everything is operated by the PC’s mouse. In other words; no computer skills are required to run this 3D software.

Join the Movement!

As an Olex user, you simply send a backup of your Olex sea floor data on floppy, ZIP or USB Memory Stick to Olex AS (the local distributor or dealer often does this for their customers). Olex AS will do a careful quality check of your data and send it back to you together with all data available in the shared Olex database. Physical variables, such as water sound speed and weather effects, which normally would reduce the quality of such a low cost survey, are offset by the repeated collection of data, employing statistics in order to accurately map the sea floor. “This is a unique no-cost service offered by the manufacturer, and a huge amount of the Olex users choose to share sea floor data for mutual benefit”, says Ørsnes.

Multibeam Data Available in Olex

Many research and survey vessels have high-tech equipment like multibeam echosounders. These echosounders collect several hundred soundings simultaneously, and can map huge areas in a short time. The multibeam sea floor information is more precise than that of a regular single beam echosounder, and offers a more detailed and accurate picture of the sea floor. This high-quality sea floor data has until recently only been accessible using very expensive equipment.

Olex AS now has access to multibeam data, and has already included parts of the Icelandic coast in their shared database for all Olex customers to use. This will be a very important resource for fishermen and navigators all over the world. According to Ørsnes, increasing the multibeam sea floor data is the main focus of Olex AS right now. “We are getting access to more of this valuable data as we speak, and during the course of this year we expect to include multibeam sea floor data from additional ocean areas.Our database is growing rapidly due to our customers sharing their data and to other sources giving us access to already available multibeam data”.

Established in 1997, Olex AS has had a constant growth in revenue. For several years they have been ranked amongst the fifty fastest growing technology companies in Norway, and are listed in both the “Deloitte Technology Fast 50” for Norway and the “European Technology Fast 500”.

Olex 2.7: Animated lights, arrival time display and smooth movement of the ship

Several navigation features has been added to Olex in the new version 2.7.  Now the navigator will see the lights in the chart as they are - flashing in the same colour and with the same character as the real lights.  The colour will change as the ship enters a new light sector, making the dark navigation less complicated.

A special feature for the passanger boats are the arrival schedule window. The timetable is always correct, and takes into account the different delay times for the different harbours. If some of the harbours are skipped, the timetable will change according to the new route.

The position of the ship between the GPS fixes are now beeing calculated. This gives a more correct visualization of the position and speed.

2 August 1999:
