1. Always place unit horizontal that ROT requested;
2. If using own AIS receiver that “AIS ANT”should lift up then pull out the “AIS ANTENNA BAR”
to obtain good AIS signals;
3. The “GPS ANTENNAAREA”should be facing up to the clear sky in order to obtain
good GPS signals;
4. To replace new battery by release the Battery Lock “14” then slide Battery “15”
(Note: The spare battery must be full charged before long time saved)

BASIC OPERATION：
SHIP AIS PILOT PLUG MODE:
Default output data on unit are: GNSS,ROT,AIS Receiver on NMEA sentence,user can make them
OFF in unit MENU to let it worked with ship’s AIS Pilot Plug, it will repeat ship’s data after both
OFF.
Recommend setting:
SOG,COG,HEADING from ship and ROT from KSN55-C(Make the GPS OFF in unit MENU)
Note: Own AIS receiver will OFF automatic afterAIS cable connected to ship,so it can at ON
always.
INDEPENDENT AIS MODE:
This mode is for backup normally when ship navigations are not working.
The GPS,ROT,AIS,HDT should be ON in unit MENU,Heading value must be initiated in the web
page “192.168.2.1/ksntek.html’CAL option.
Note: ROT CALIBRATION will requested if it opened whatever ship mode or own ,HDT not
recommend to use for the moment.

ROT CALIBRATIONS：
The calibration of ROT on equipment is very important before use it. the value of ROT will be
inaccurate if it not calibrated correctly. ROT status should be observed after each boot. unit
has the functions of automatic and manual calibration. please follow below steps:

KSN55-C SERIES USER MANUAL
WWW.KSNTEK.COM
1.AUTOMATIC CALIBRATION：
HOW IS THE AUTO CALIBRATION WORK:
Firstly, do not connect the AIS cable before power on.place unit horizontal position and keep the
device relatively static. ROT will automatically calibrate within 10 seconds after booting. Then
the iPad or laptop will connected with device byWi-Fi, open navigation app or observe the value
of ROT through the device screen. If the ship is at berth or in a steady course, the ROT will
display 0°/m or return to zero automatically. That means device has been automatically
calibrated successfully. At this time, the AIS cable can be connected then keep relatively static
which will cause the output value of ROT to change during the wiring process, but after being
stationary, It will return to zero automatically and the automatic calibration process will end. On
the contrary, if the ROT value is not 0°/m after turn on or it will not return to zero automatically,
the following manual calibration is needed.
2.MANUAL CALIBRAION：
Short press once the Power and M button at the same time for manual calibration or open the
IE browser or Safari, enter the address “192.168.2.1/ksntek.html” in the address bar (please
type all the letters including the end “html”and lowercase letters, pay attention to the direction
of the slash) and enter, the page will open as the following and click the CALIBRATE button to
manually calibrate the device, if the calibration is completed. ROT will return to zero
automatically. This step will not request internet connections, the page was integrated in unit.

HDT: heading from KSN55-C,it can be Enabled or Disabled in this page;
CAL: the heading in KSN55C need to input value for initial,input a value then tap on SEND,unit
must be no movements after the value set.
UNIT MENU：
All functions on the device can be turned OFF / ON through the menu options. Press and holding
M key for 3 seconds, it will enters the device operation menu. Use M key to chooses and Power
key enter the sub menu and SET.
CONN:
To SET connections module ON/OFF in this MENU, Power key ENTER and SET,M key select.
NAVI:
In this menu can set own AIS, GPS, ROT, HDT to be ON/OFF,mostly use when KSN55-C working on
Ship’s AIS Pilot Plug.
AIS: Own AIS receiver can ON/OFF automatically after connected AIS cable to ship’s AIS pilot
plug or manually in this menu.
GPS: Own GNSS receiver, it will post NMEA sentence together with ship’s AIS after connected
AIS cable if it ON, can set it OFF when use ship AIS pilot plug mode.
ROT: Own Rate of Turn sensor, it will post NMEA sentence together with ship’s AIS after

connected AIS cable if it ON, it can left with ON if ship AIS not provide ROT data.
HDT:Own Heading sensor, the factory default is OFF, recommend to leave it OFF when use ship
AIS Pilot Plug mode.
SYS:
If some settings wrong or forget what have set that can be reloaded to the factory default by SYS-
RELOAD. The factory default are: WiFi, Bluetooth ,USB,AIS,GPS,ROT with ON status.
If entering Firmware update just press and hold the Power key to exit then unit will OFF then
power on again.
HELP:
This menu contains parameters of unit like Host IP address and WiFi network password, the
Bluetooth pair key not requested anymore in this version.
Wi-Fi SETINGS：
On the latest products from KSNTEK that allow end users to customize on Wi-Fi settings like SSID
NAME and Network Password...etc, this will avoid some unexpected connections due to the WiFi
