• "GPS Error": Value is always >10 m. Used as a hint regarding the
accuracy class of the internal GPS. Normally the GPS of the TRX2S
will be >10m.
• "Satellites in view/used": Shows the number of received GPS
satellites and how many of them are used for position fixing.
If you have an unit with “iGPS” you can check here if your
mounting position is good to receive the GPS signals.
• "Transmitter": Once the transponder has sent data for the first
time, the status changes from "Standby" to "OK". If there is any
fault in the device, "Error" is displayed and the device does not
work properly anymore (needs repair). The box “Error Message”
gives information about the error.
• "Receiver": When the device has received AIS data for the first
time after switch-on the status changes from "Standby" to "OK".
If there is any fault in the device, "Error" is displayed and the
device does not work properly anymore (needs repair). The box
“Error Message” gives information about the error.
The "Hardware Status" displays the value of operating voltage.
Important is the value stated in "Supply Voltage (TX)". This is the
voltage level during transmission. Here the easyTRX2S device is shortly
drawing approx. 2 A. If the cables are too thin and very long, the
voltage may drop down well below the "Idle"-level (resting value)
which might guide to a lower radiation performance. Perhaps you
should consider using cables with larger copper diameter and check all
contact connections, respectively.
The values RSSI1 and RSSI2 give information, if there are any interferers
on the two AIS frequencies. This may be caused by e. g. a faulty
electrical device on board. If there are no interferers the status is "OK".
"TX Forward Power, TX Reverse Power" are OK if the connected VHF
antenna is working properly. If the antenna has short circuited or the
antenna cable is disconnected "Error" is displayed.
The value of forward power should be always three times bigger then
the reverse power.
