Quick Introduction

With GAMP-2000 you can connect various NMEA 0183 and NMEA 2000 based system. Boat
instruments, GPS, AIS, PC, Autopilot are connected together and the data are sent even
through the NMEA 0183 ports, NMEA 2000 port or the Wi-Fi connection.
It is possible to connect via Wi-Fi up to 4 devices capable to receive and transmit NMEA 0183
data, such as iPhone, iPad, iPod touch and Android devices.
The GAMP-2000 have an NMEA 2000 port capable of communicating on an NMEA 2000
network. NMEA 2000 messages (called PGN’s) are translated into NMEA 0183 sentences. The
GAMP 2000 also translate NMEA 0183 sentences into NMEA 2000 PGN’s.

Unique worldwide, it allows saving navigation data by command; the management is made by
an app (iOs, in the future Android as well) which activates the recording, stops it and allows
transmitting the registrations on your portable device via Wi-Fi .

Available version which allows the use of “esa regatta” and “esa training” apps.

Esa GAMP-2000 multiplexer has three or four, depending on the version, opto-isolated inputs to
connect data sending davices, called Talkers, two outputs, to connect multiple reciving devices, called
Listeners and one NMEA 2000 interface to connect to an NMEA 2000 backbone.
Esa GAMP-2000 syncronise the NMEA sentences from different talkers and send them to the outputs.
Esa GAMP-2000 also translate NMEA 2000 messages (PGN’s) into NMEA 0183 sentences and vice
versa.
The way the sentensece are combined, is completely manageable by the user through the ‘Esa
configuration manager’ software supplied with the GAMP.

The particularity of Esa GAMP-2000, compared the standard multiplexers on the market, is that it is
not limited to output NMEA 0183 strings and NMEA 2000 PGN’s, which compared the information they
carry, have a considerable amount of data to send, but also transmit data for the navigation software
Esa Regatta, with a proprietary protocol much lighter to send thereby reducing delays introduced by
the multiplexer itself.
Is still maintained the possibility to send output Wi-Fi both NMEA 0183 and Esa sentences, for a
combined use of Esa Regatta and third-party applications.

Another unique feature of the GAMP-2000 is that inside housed a MicroSD card connector (optional
memory card not included) to be used as a data logger, a tool, that is able to record in its internal
memory all navigation data every second, to use them for subsequent analysis.
To manage the operations of reading / writing / storing these files was created an app, a free
download from the Apple Store, which is described in this manual in Section 4.

GAMP-2000 and App Esa Regatta

The “GAMP-2000-esa” comes already configured for use with App Esa Regatta, downloadable from the
Apple Store.

We recommend you to connect the output of your network NMEA instruments to In1 input of GAMP and
connect to an NMEA 2000 network with the NMEA 2000 connector, as shown in the following figure.

Note: if the GAMP-2000 is connected to an NMEA 2000 network no additional external power supply is
needed, otervise and adittional external powers suplay of 12V-24V is needed.

Once on the system Esa-GAMP-2000, scan WiFi networks with your Apple device in which you
installed Esa Regatta, then:

1. Connect to the network ESA_GAMP_2k and enter, when prompted, the password FAE95A0697

2. Enter the IP address: 192.168.1.3.

3. Launch Esa Regatta.
And advisable to change the network name and password to have no trouble connecting with other

systems GAMP-2000 that they are nearby. (see section 1.2.1 Customizing network name and
password).

11. Divisor Factor

Please Note: Always remember to click the "Commit" button to save the configuration data, sending them to
the device. The read button is used instead to read this configuration.

1.2.1 Change SSID name and Password

All Esa GAMP-2000, from the factory, have the same factory SSID and password, as shown in Step.2; in order
to avoid accidentally connecting to the GAMP of another boat, it’s recommended to change them selecting the
‘WiFi Settings’ window in the ‘File’ menu.

Select the SSID name field, putting, for example, the name of your boat, and the new password that you must
have a length of 10 alphanumeric characters, that is, numbers 0 through 9 and uppercase letters between A
and F (0 - 9, A - F).

WARNING! The process of retrieving the user password requires intervention of a technician Astra

17

Yacht, we recommend that you write down the new password so that you can find when needed.

1.2.2 Select WiFi channel

From software version v1.3 will be able to set the WiFi channel on which the network work. This allow the user
to select the most appropriate channel, thus avoiding problems due to interference from other wireless
sources that operate on the same channel.
The choice of channel is very simple:
Once the reading of the parameters of the dongle (Read button), go in File> Wifi Settings, and select the
favorite channel. Then click on the button "Ok" if the configuration has been successful, you will be prompted
to restart the dongle, otherwise an error message will prompt you to repeat the setting.
Channels 1,6,11 are recommended.

1.2.2.1 Firmware Update

The new versions of the configurator software allows a firmware update of the dongle. When selecting the
menu option File->Firmware Update a dialogbox will appear as shown in the following figure. Pleas select the
.hex file optained from the Astra website or obtained by email.

Wait the firmware update process to finish. The status bar show the update process as shown in the following
figure.

18

After the firmware update finish reset the dongle the new software is loaded.

1.2.2.2 Software Versions

The new versions of the configurator software will be equipped with a recognition of the firmware of the
dongle. Such recognition will serve to protect the integrity of the same, as a different version of the firmware
may result in new functionality that is not managed by an old configuration, so you must have the configurator
for the firmware version that you have installed. For this reason, in case you are using a version of the
firmware does not conform to the dongle, a message will appear that will allow you to use the configurator at
your own risk, and you should ask them to use the appropriate version:

19

In case however, you use a configurator does not conform to the type of dongle which you possess, you will
receive a message that forces the user to use the configurator correctly. When this message appears, the
configurator is "disable" in its entirety, except that the display of instructions sent on Wifi.

1.2.3 Baud Rate

For each input NMEA 0183 you can set the baud rate in the entry/exit of 4800 and 115200 baud (symbol/sec).
The setting of this parameter is important for the proper functioning of the device, because if for example 1
input is connected to a device running at 115200 baud and 4800 baud sect user, definitely will not receive the
correct data, compromising the functionality of the device.

20

1.2.5 Filtering sentences

The Smart Dongle allows you to filter the input NMEA 0183 sentences in such a way as to display and
multiplexed together only what is needed. NMEA 2000 messages (PGN’s) are translated into NMEA 0183
sentences and vice versa. Therefore the filter feature of the multiplexer still works on NMEA 2000 messages,
NMEA 2000 PGN’s are first converted into NMEA 0183 sentences and then filtering and routing is applied.

First the sentence must be acquired in capture mode by pressing the Capture button. With this functionality
the configurator starts listening for 20 seconds (you can also block previously pressing the same button again)
of incoming NMEA sentences on Wi-Fi. After the capture process is finish all the sentence are displayed in the

filter table as show in the following picture. Sentences could be removed by selecting the sentences and
pressing the Remove Rule/s button. All rules coud be removed by pressing the Remove All button.

The first coloum T.ID in the filter field is the talker identifier the second field Sent.ID is the sentence identifier,
follows the input ports, the division factor and the output ports.

Then check boxes in the green fileld show on wich input the sentence was acquired, where NMEA 0183 input
ports are In1, In2, In3 and In4, the GPS port (depend on dongle type) and the NMEA 2000 translated
messages virtual port N2K. If the input check box is selected the input will be processed by the dongle if not
the sentence will be ignored.

The check box in the red field allows to select wich sentences will be routed to the NMEA 0183 output (Out

0183), NMEA 2000 output (Out N2K) and WiFi output (Out WiFi). To the NMEA 2000 output is possible to to
route (translate) only sentence from the NMEA 0183 ports.

21

The divisor factor Div is a configuration parameter that allows you to divide by the factor included the number
of judgments that are sent in the outputs (NMEA 0183 – Out 0183, NMEA 2000 – Out N2K, WiFi- Out WiFi).
For example, if a heading sensor send 10 data per second, putting a divisor factor of 5, it will send only 2,
others will be discarded. This feature is used in the event that some tools have updates data too fast and not
necessary, everything could create overflow. To access, press twice on the cell shown in following figure, and
by means of the spinbox or by typing it, you can set a divisor factory up to 99 Max.

In order to apply all filter setting the Commit button must be pressed.

22

1.2.6 Input Priority

This option eliminates NMEA sentences duplicate receipts on most inputs. When it is enabled, the multiplexer
will assign a priority (settable through the fields) to incoming data based on input that is received. For each

input you can set the priority from 1 to 6, where the priority 1 is the highest priority. As an example this function

may be useful to set a second GPS as a backup to the main GPS. If for example two GPS receivers are
connected 1 entrance and 2, where the input 1 has priority higher than the entrance 2, receiving a judgment

the judgment --RMC, just the one coming from the GPS connected to input 1 is passed out, the other is

blocked unless it is past the time out selected.

23

1.2.7 Check GPS feature status and time out

If you have activated the "Enable Priority", are discarded NMEA data repeated from lower-priority ports.

Through enabling flag "Check GPS Satus" judgments are corrupted or not valid from the GPS, so that if
another GPS is connected as backup is re-enabled, whereby a judgment is entered in duplicate buffer. The

judgements are verified: APB, GGA, GLL, RMA, RMB, RMC, VTG , XTE.
The "TimeOut" field identifies a time that, to overcome the same, a lesser priority input is enabled to output a
duplicate sentence from an entrance to highest priority.

24

1.2.8 Convert NMEA sentences

It is possible to automatically generate a corversione of sentences as follows:
HDG-> HDT
If this option is enabled, the multiplexer will generate a sentence HDT (true heading) when it receives a
sentence HDM or HDG (magnetic heading). If the HDG sentence contains a magnetic variation, this value is
used to calculate the "true heading". Otherwise, the value is copied. The originals HDM and HDG sentences
are also forwarded to the output, but if you wish, can be blocked using the filter. This option can be useful for
example in the case of satellite phones which need "true heading" to be able to direct them towards the
correct antenna for satellite communication.

VTG-> VHW

If this option is enabled, the multiplexer will generate a VHW sentence (water speed and heading) when it

receives a VTG one (course over ground and ground speed). VTG sentences is generated by a GPS, instead
a VHW sentence is generated from log and compass.
You can use this option if your boat hasn’t log and/or gyrocompass sensors.

1.2.9 Select Depht data

NMEA standard provides two types of information for the depth measurement:

 DBT (Deep Below trasducer) that indicates the depth measured from the sensor;
 DPT (Depht) that indicates the relative depth with an offset entered by the user. Usually you add, as an

offset, the immersion of the sensor in order to have the depth from the sea surface, or you can subtract
the distance that exists between the sensor and the bottom of the keel, to get an indication of the depth
below the same.

In this window you can choose what information to display and set the desired offset regardless of the settings
made on-board instrumentation.

1.2.10 Bypass the buffer (Real Time)

The real-time option bypasses the queue for a specific input. During normal operation, all incoming NMEA
sentences are stored in a queue, one for each channel, which can contain a few seconds of NMEA data. In
heavy traffic situations, these queues can be filled quite quickly until an overflow occurs. If it happens, will turn
on the red LED of the multiplexer and overflow indicators to the right of each entry section where an overflow
occurred.
Occasional overflow does not pose an immediate problem, but it just means that sometimes a NMEA
sentence in input is discarded because there is more space in the queue.
However, when a device is connected, that sends NMEA sentences 10 or 20 times per second, the
corresponding input queue in multiplexer fills constantly generating a situation of constant overflow, causing
an unacceptable delay information up to 20 seconds.
By enabling real-time option for fast entry (e.g. Gyro), its tail is bypassed, input and output is sent directly
without buffering delays the first valid NMEA sentence from the input. Some NMEA sentences are discarded
when the multiplexer is working on another entry, but this is far less problematic than having 20 seconds of
delay in information.

26

1.2.11 Congestion Display buffer (overflow)

The overflow bars are populated based on the traffic, the Red led on the device lights up overflow is reached
indicating a misguided Smart Dongle configuration.

1.2.12 Ability to modify the talker identifier

The Smart Dongle allows you to change the Talker ID judgments. The Talker ID consists of the first two
characters of a string and determines which NMEA instrument (talker) the judgment originates.

27

28

1.2.13 NMEA/ESA Routing or Merge Mode (only for GAMP-2000-esa)

The Smart Dongle allows you to send outgoing WiFi on both proprietary ESA judgments, which represent a
standard owner Astra Yacht by means of which you can use the ESA navigation software, both judgments
Regatta NMEA standard. Thanks to flag "Enable Channel ID" you can view the provenieza channel of each
entry posted on WiFi (as long as it is selected, the mode of sending NMEA sentences).
In addition, if you wish to use various devices with different client programs, you can set up a Merge mode that
allows you to get on Wi-Fi both NMEA sentences, proprietary and ESA.

29

1.2.16 Internal GPS Setting & ESA Setting

The version of GAMP-2000 has two additional settings that can be recalled with buttons at the bottom left of
the page in the Configurator.

ESA setting

Through this window, you can increase the refresh rate of the ESA sentences, ie the number of times that the
the ESA sentences are sent by the GAMP at the devices connected to it.
In addition, this setting also increases the refresh rate of the bars overflow on the configurator.

30

GPS Setting

The internal GPS (onlydonglewith this feature) has the possibility to transmit data at frequencies of 1, 5 or
10Hz (1Hz default)
If you want to have a frequency higher than 1Hz, you need to set a baud rate greater than or equal to 38400.

1.12.17 Info, Warning and Error messages

The user, in the case of inclusion filter rules, setting the SSID of the Wi-Fi network, connection to the device is
alerted with a pop-up message.

Connection
In case of successful connection, you will see the status "Connected" (instead of "Not connected") in the task

bar at the bottom of the window:

31

In case you have trouble connecting, you will see the following message:

Wi-Fi Setting
As in the previous case, even when you set the SSID of the wireless, you may be one of the following

messages:
Place Setting
In the case of the correct change, the user will be notified with the following message:

In this case, the user, to access the new network at the SSID is defined by him, must perform a system restart.

No Changes Made
In case the user re-enter the same SSID or do any changes, you will receive the following message:

32

Setting problems
If there are problems, related to device or with respect to the change made by the user, the latter is notified

with the following message.

In this case, you should double check your settings and try again, or restart the system.

Step 2: Third-party Software Link

The ESA dongle enables connection via Wi-Fi to third party software for analysis of multiplexed NMEA
sentences. The connection must be made using TCP/IP Protocol by connecting to the address 192.168.1.3
and brings 44300 once connected to the wireless network created by dongle (SSID: ESA_GAMP; Password:
FAE95A0697).

33

Step 3: Hardware connections

3.1. Introduction.

The NMEA 0183 v2.0 standard and later, use a differential signalling scheme, in order to
ensure better insulation from noise than previous versions that were using 'single-ended' or
RS232 signalling scheme, ie with a single cable for data and a ground terminal (GND).
Connect equipment type 'single ended' with the new equipment of the differential type, can
cause damage or malfunction, as the terminal NMEA - / B is forced to the ground with the
possible consequence of heating and damage to the power supply circuits.
To overcome this problem, since the market still exist many devices 'single-ended', the
GAMP-0183 has two opto-isolated inputs, fully compatible with RS232 signals.

3.2. Connecting to differential NMEA devices

If the device is fully compliant to the NMEA 0183 standard, then simply connect the output
terminals A/+ and B/- of the talker to the input terminals (+) and (-) of GAMP-0183.

3.3. Connecting to a single ended NMEA device

If the talker uses a 'single-ended' signally scheme (in the case of some antennas GPS, AIS systems or
personal computer), you must use the inputs NMEA NMEA In 2 and In 3 of GAMP-0183, connecting
the data Tx to the input terminal (+), and the GND terminal to the input terminal (-).

Step 4: SD Data Logger Managment (ADR)

4.1. Introduction

The GAMP-0183 housed inside a MicroSD card connector (optional memory card not included) to be
used as a data logger, a tool, that is able torecord in its internal memory all navigation data every
second, to use them for subsequent analysis.
To manage the operations of reading / writing / storing these files you must use a free App, the ‘ADR
Astra Dongle Recorder’ downloadable from the Apple Store, which is described in in the follow
section.

4.2. App Astra Dongle Recorder (ADR)

ADR, Astra Dongle Recorder, is an App that once connected to the GAMP-0183 acts as a remote
control for the operations of reading / writing to the memory card micro SD (optional).

4.2.1 Connect to the GAMP-0183.

Press the Settings button to access the setup page of the IP address of the dongle.

Set the IP address shown in the figure, corresponding to the address of the router GAMP­0183, and press the 'Save' button to return to the main page.

35

The selector 'Demo mode' allows to use the application even in the absence of a connection
with the GAMP-0183, for practice in the use of the same.

4.2.2 Start Recording.

Pressing 'Start Recording' you enter the page of the log files recorded in the memory card.
You can choose to continue to write to an existing file, by selecting the same from the list, or
create a new one using the button 'New Log File'.

4.2.3 Read SD card

To manage the files on the card press the 'Read SD' button.
You will see the list of files in memory; by clicking on one of them will open a page for deleting
or downloading it on the Apple device.

36

4.2.4 My Files.

Show the filelist stored in your Apple device, loaded from the SD card using the download
seen above.
These files can be sent with an e-mail to your computer for further processing.

Another wayto download a file on your PC is to connect the Apple device to iTunes and go to
the App→File Sharing section.
Select the application ADR AstraDongle and will appear on the right the file list stored in the
device, select the file you want to copy to your PC and press 'Add' to select the destination
folder.

37

4.2.5 Description of log files content

Below are the specifications of the contents stored inside the ADR file, that is a .txt file but can easily
be opened in other formats for the necessary calculations.
The file consists of a string for every second, containing different values, comma separated , in
which are the recorded data supplied by the onboard instrumentation connected to GAMP.
Below Is an example of the structure of the strings:

$ESA,Ts,ax,ay,az,Time,Date,AWA,AWS,AWS1,TWA,TWS,TWS1,BS,HDGt,HDGm,Lat,Lon,Lon1,Fix
,Depth,MagDev,MagDev1,MagVar,MagVar1,Temp,SOG,TrackT,TrackM,checksum

Below is the code of the recorded data and the relative position within the string. It starts with $ESA,
note that not necessarily within the various fields appearing all data, for example if the GAMP is not
connected with some instrument measuring the accellerations, the corrispondent fields will be empty
(comma separated)
