Thank you for choosing our Saiyang electronics AIS9000 Class B Automatic
Identification System (AIS).
Please read the manual carefully before installation and using our products
to ensure correctly use and make the best use of its advantageous functions. Please
keep the manual properly in order to refer when troubleshooting and maintenance.
Warning: Please do not dismantle the machine. AIS product is a complex system.
Exchange any of its components can affect the working performance of the system.
Please contact professionals to commissioning the device.
Notes: Please correctly use the device. Set and use the product according to
regulations correctly. AIS terminal product is a part of AIS network system.
Wrong setting and misuse may affect the work of the whole AIS network and other
AIS devices from the other vessels.
Notes: Pay attention to the power supply. This device adopts 24V DC power supply.
Please check the provided voltage and polarity before connecting to the vessel
power supply. Wrong connection may cause damage and scrap of the device.

1. Product Description
AIS9000 is made up of a TDMA transmitter, two TDMA/DSC receivers, a AIS processor,
a CPU, a internal GPS receiver, power module and interface circuits, etc.
AIS9000 can work independently on two channels, set zero by receiving message
22 and work by transferring to other water channels.
The Class B AIS transponder’s two channels can work between Frequency
156.025MHz～162.025MHz water channels. The device’s default working channels are
Channel 2087 and Channel 2088. When the base station shift to the other working
frequency that is out of the above working frequency channels or 25KHz bandwidth by
remote control command, the device will convert to only accepted status.
Notes: Important Hints
1. The manual is mainly for operator usage. Initial settings of the device are
not provided in the manual. Please consult manufacturer and agent for
specific details.
2. The functions that described in the manual may have some differences of the
products you have bought. But it will not affect the normal usage of the
device.

The device has an internal GPS receiver, providing location, time, Course over
Ground (COG) and Speed over Ground (SOG) data. Positioning accuracy is about 10m.
When the device receives the message 17 from AIS base station, position data will
convert to high precision Differential Global Positioning System (DGPS) position.
Accuracy can reach 1～2 meter(s).
When GPS do not positioning, the device will not transmit. But when the base
station adopts consulting ways to ask the marine radio for sending, the device will
get the basic time from consulting instructions and conduct one emission.
The device transmits the following AIS data.

The Class B AIS transponder has five indicator lights: power supply, GPS, RX, TX,
troubleshooting; a SOS button. The definition is explained as follows:
Indicator Lights
Definition
GPS Positioning
Flash Green Light means GPS position is valid; Constant Green
Light means no valid GPS position.
RX
Flash green light means receiving AIS information. The more
flashes, the more AIS targets around or RX is working well.
TX
Flash red light means the device is sending the AIS
information.
Flash once means sending once. Sending once every 30 seconds
or 3 minutes normally, therefore, it is hard to observe its
sending. status.
Troubleshooting
Constant yellow light means there is something wrong with the
device.
Power Supply
Red light means power on.
SOS
Press the button, it will send the distress signal.
Notes:
1. Base station can remotely change the dynamic data emission intervals ( 5 seconds
to 10 minutes) by message 23 or set silence period according to different areas
or vessel type.
2. Factory set the default vessel type to be yacht.
3. Factory set the vessel MMSI to be 000000000

3. Installation
When choosing the GPS antenna installation location, please pay attention to
the following points:
Selected location should keep away from radar radiating wave, which will destroy
or affect the GPS satellite signal reception.
There is no obstruction in the line of sight of the satellite. Obstruction (such
as mast and so on) in sight will stop signal reception or extend satellite
searching time.
The higher the installation location, the better. On the one hand, it can avoid
obstruction; on the other hand, it can avoid splashed by seawater that will affect
reception.
Notes: Make waterproof treatment of the cable joints.

3.2.1 Installation location
Please consider the AIS VHF antenna installation location carefully. Compared to
analog communication, digital communication is more sensitive to reflection
interference from the obstructions of iron tower, mast, etc.
