ECHOTRAC ETHERNET INTERFACING WITH HYPACK MAX

2

Before the user can interface and use the Ethernet interface from Hypack the unit must be setup with Echotrac CV Control Software. OHSI developed the CV Control software for the following devices:

Echotrac model CV

MKIII PMKIII E

The Echotrac model CV must be controlled by CV software. The control for the MKIII can be either front panel or via ethernet control software.

The Echotrac CV is a new hydrographic echo sounder design incorporating the cutting-edge technology, features and reliability of the Echotrac MKIII, plus the ease and flexibility of operation of a networked Windows®®®® interface. The transceiver unit is supplied in a compact rack mount package that is ideally suited to many shipboard installations. The Echotrac CV supports Chart-functionality in two formats, a full size color LCD “electronic chart” or a high-resolution thermal paper recorder. Both are supplied in flexible modular enclosures complete with swivel mounting hardware. A third option, that of operating the unit and collecting data on a networked PC, is also possible. The color LCD module offers internal data storage (in .XTF format) and playback of the analog return signal digitized to full 16-bit resolution. In addition, the Echotrac CV offers the possibility of adding a third acoustic channel (X3) to the standard dual frequency (X2) configuration. All channels feature a robust design and frequency agility enabling the operator to precisely match the transceiver to almost any existing transducer. Operator selectable TVG curves (10 Log, 20 Log, 30 Log, 40 Log, and Off) serve to optimize the MKIII for both shallow and deepwater bottom detection tasks and for Sonar imaging. The Echotrac CV features unsurpassed interfacing flexibility, offering 4 serial ports that can be configured to interface with computers, positioning systems, motion reference units and remote displays. The Echotrac CV also has an Ethernet port that outputs the 16 bit samples of the acoustic data for further processing or visualization. The Echotrac CV also supports a number of output formats that are compatible with most common Echo Sounder strings.

The Echotrac MKIII and Echotrac CV have an Ethernet port that outputs the digitzedsamples to 16 bits of the acoustic signal from the unit's receivers. This data has normally always been printed on the chart or more recently output to an LCD screen and only the digitized values have been input into the hydrographic software that is logging and editing the data. To fully leverage the power of having all this acoustic data available Odom Hydrographic Systems Inc. and Hypack have developed an Ethernet driver that will read in the acoustic data into Hypack as well as the digitized values. All the normal fix marks are still printed on the chart or displayed on the LCD screen. The real power of having the data available in Hypack comes into play when the surveyor goes to review and edit the data. Instead of only having a digitized line on the screen and then having to refer back to the chart for reference, all the acoustic data is in the background. The surveyor can now edit the digitized data with much more precision and confidence. The raw acoustic data is never altered during the editing process.

The Ethernet interface in Hypack will only work with Hypack version 2.12 or later.

TERMS YOU MIGHT NEED TO KNOW

ETHERNET ETHERNET ETHERNET ETHERNET ---- A standardized way of connecting computers to create a network.

CLIENT CLIENT CLIENT CLIENT –––– A computer that has access to the network but doesn’t share any of its own resources with the network.

I/O PORT ADDRESSI/O PORT ADDRESSI/O PORT ADDRESSI/O PORT ADDRESS – Every I/O device in a computer – including network interface cards – must be assigned a unique address. In the old days, you had to configure the port address using DIP switches or jumpers. New network cards automatically configure their own port addresses.

IP ADDRESS IP ADDRESS IP ADDRESS IP ADDRESS – A string of numbers used to address computers on the internet.

PACKETS PACKETS PACKETS PACKETS ---- Data is sent over the network in manageable chunks called packets, or frames. The size and makeup of a packet is determined by the protocol being used.

PROTOCOL PROTOCOL PROTOCOL PROTOCOL ---- Protocols define standardized formats for data packets, techniques for detecting and correcting errors.

SERVER SERVER SERVER SERVER –––– A computer that is on a network and shares resources with other network users.

TCP TCP TCP TCP –––– Transmission Controlled Protocol, the standard for transmitting data over networks.

UDP UDP UDP UDP –––– User Datagram Protocol, a connectionless protocol that, like TCP, runs on top of IP networks. Unlike TCP/IP, UDP/IP provides very few error recovery services, offering instead a direct way to send and receivedatagrams over an IP network. It's used primarily for broadcasting messages over a network.

Basic information concerning Ethernet cables

•A straight-thru cable has identical ends.•A crossover cable has different ends.•A straight-thru is used as a patch cord in Ethernet connections.•A crossover is used to connect two Ethernet devices without a hub or for connecting two hubs.•A crossover has one end with the Orange set of wires switched with the Green set.•Odd numbered pins are always striped, even numbered pins are always solid colored. •Looking at the RJ-45 with the clip facing away from you, Brown is always on the right, and pin 1 is on the left.•No more than 1/2" of the Ethernet cable should be untwisted otherwise it will be susceptible to crosstalk.•Do not deform, do not bend, do not stretch, do not staple, do not run parallel with power cables, and do not run Ethernet cables near noise inducing components.



10

If the Echotrac is going to be connected directly to the computer then a Cross over Ethernet cable is required. This is the red Ethernet cable supplied with the Echotrac. If there is a network hub between the computer and the Echotrac then a straight network cable is required from the Echotrac and the network hub.

Cross-over cable part # 2300-0053-0000 Supplied with unit.

If you are interfacing through a network hub

A hub connected straight to a computer (not a server) offers the same setup IP address as a setup with the Echotrac connected straight to the computer using the cross over cable. Using a device such as the one below would require a straight cable from the Echotrac to the hub and a straight cable from the hub to the computer. A computer running on Windows® 2000 or XP operating system first “looks” for the server. If none is detected then it set the default IP address (amount of time – three minutes).

First setup all hardware. Turn On the Echotrac CV, Computer and DGPS receiver. The same Ethernet cable will be used to establish communications for the CV that is used for the Hypack interface.

Install the CV control software. Upon purchase you will be given the latest version of software. Simply insert the diskette run the file named setup.exe and follow instructions.

With the hardware connected, the user must wait three to five minutes for the computer to “find” the correct network settings or an IP change fault will appear.

From the Start button, go to Programs, to Echotrac_CV, then Echotrac_CV.



15

Once the software loads, this “pull down” screen will appear.

The Target window allows the user to select the model CV, CV3 or MKIII. This takes you to the main window.

Software begins



16

From the Main window, check your connection first. Select Info, then Connection.

If your Connection window reads like the following, then you have established proper Ethernet address.

This address is correct!



17

If you do not have proper IP address, you will see a window similar to below. If this happens, again exit the software, wait three to five minutes and restart the CV Control software.

Make sure the Ethernet crossover cable is connected from the CV to the PC.

This address is incorrect!



18

Once you have the correct address, go to Control, then Open Connection.

Open Connection



19

The software should start to synchronize.

At this point if for some reason the Ethernet address is not correct. A screen like this one should appear. Exit from the software. Then wait three minutes. Your computer should find the correct network settings.

Even though this might have taken a little time, the user should have established connection. If not, shut everything down, check the interfaces, start the CV hardware, restart your computer, wait a few minutes then start the CV Control Software.



20

At this point connections should be established.The initial screen will inform the user that the hardware and software are communicating. Note the depth readings.

Begin setting up and calibrating the Echotrac CV as per instruction manual.
