General warnings
All marine Automatic Identification System (AIS) units utilize a satellite
based system such as the global positioning satellite (GPS) network to
determine position. The accuracy of these networks is variable and is af-
fected by factors such as the antenna positioning, how many satellites
are used to determine a position and how long satellite information has
been received for. Therefore it is desirable wherever possible to verify
both your vessels AIS derived position data and other vessels AIS derived
position data with visual or radar based observations.
Warnings and precautions
It is the sole responsibility of the owner/operator of the ship to com-
mand the vessel safely and to be in full control of all operating condi-
tions during the entire travel time. By mistaken conduct of the operator
of a ship equipped with a easyWATCHBOX if the operator does pay un-
divided attention to operation and surrounding condition damage or
personal injury may be caused in the event of an accident.
Caution:
It is the duty of the operator to handle the easyWATCHBOX with care.
The device cannot release you from your obligations of due diligence!
Thus it is important at all times to keep a proper lookout.

2Mounting and Installation
2.1 Electrical installation
The easyWATCHBOX is equipped with 5 colored wires.
Power (+) (12-24VDC) - red
Power (-) - black
NMEA (+) - white
NMEA (-) - green
Special Function (+) - grey
The AIS output must be set to 38400 baud data rate.
If you have a chart plotter connected to the AIS, you just connect the
easyWATCHBOX in parallel. (Please see following figure)

Electrical self-check:
The easyWATCHBOX has got an internal self-check, which gives you in-
formation, about the status of power, GPS and AIS data.
The Bat.-low LED should always light up green.
If it lights up red, the supply voltage is too low.
When no AIS data is available (AIS receiving unit is turned off, or
maybe a broken wire), or CPA-alert is deactivated, the LEDs for time
and distance are turned off at all.
When GPS and AIS data are going into the easyWATCHBOX, the ac-
tual setting LEDs (one for time and one for distance) show green
light.
The blinking of LEDs for time and distance indicates the standby
mode of the easyWATCHBOX (GPS data is available, AIS data not).
When AIS signals are being received, the LEDs are lighting up.
When AIS signals are missing or lost for at least 30 sec (so only GPS
data are available), the easyWATCHBOX changes over to standby
mode again and the LEDs start blinking.
The easyWATCHBOX needs GPS-NMEA data and AIS-NMEA data. Only
when both data are available, the watch box can calculate the distance
to other ships and possible collision scenarios.

2.2 Mechanical installation
The easyWATCHBOX is not sealed and therefore intended only for use
inside of ship. It can be mounted with 4 screws.
Please ensure that there is a gap between the back of the device and
the wall or floor, to not decrease the volume of the integrated buzzer.
3Using the easyWATCHBOX
The intended purpose easyWATCHBOX is an alerting device, which anal-
yses the NMEA data output of an AIS receiver or AIS transponder.
On the basis of these data it analyses alarm situations like AIS-SART
(Search and Rescue Transmitter), or it calculates collision scenarios.
Whenever an alarm situation is detected, the LEDs show, which kind of
alarm has occurred and the internal buzzer gives a loud signal.
With the buttons you can either turn on and off the acoustic alarms or
you can set-up the collision alarm parameters (alarm distance and time).
ATTENTION:
The collision alarm is only available, when the AIS has got also GPS data
on the NMEA output.
The AIS-SART alarm works almost with all AIS systems in the market.
Moreover the easyWATCHBOX features a deep discharge protection, an
external horn drive and a trigger function for an auto dial-up device.

3.1 LED Indication
Collision:
Lights up, in case of danger of collision with another vessel or AIS-
target.
AIS SART:
Lights up, when an AIS-SART signal was received.
Bat. low:
Changes from green to red, when the battery voltage falls below a
dangerous limit
Time LEDs (5, 15 and 30 min):
Indicating the time limit, that you have selected for Collision warn-
ing (CPA)
Distance LEDs (100, 200, 500 m):
Indicating the radius limit that you have selected for Collision warn-
ing (CPA).

3.2 Buttons
Mute SART Alarm:
By pressing this button, the AIS-SART buzzer alarm is turned off. To
turn it on again, please press this button for more than 3 seconds;
you hear as confirmation a short double tone.
Settings:
With the both "Settings" buttons the Collision parameters can be
changed.
By pressing both “Settings” buttons together for more than 3 sec,
the collision alert is turned off. The Time and Distance LEDs will go
out.
To reactive CPA Alert, simply press one of the both “Settings” but-
tons.
ATTENTION: After 30 minutes all disabled alarms are turned on auto-
matically for your safety!
