1.1.2 Multi-function cable
To make user connect the device easily, there is a set of cable provided with the device.
One side of the cable connects “Power & Data”port of the device. Thereare two types
of signal at the other side, power parts and RS-232 femaleconnector.
In power parts, Red is for +ve 9-33VDC input and black is for power ground.
Please make sure positive pole of your power connected with the red
wire,otherwise the device will be damaged!

2 Functions
2.1 Device initialization
After host powers up, four indicators will fully light for 1 second, then fully turn off. Later,
terminal starts to initialization process.
If GPS module works well, after GPS has valid positioning, "GPS indicator" will start
blinking.
Meanwhile, GSM initialization begins. If initialization is successful, "GSM indicator" lights,
then dial to centre server. After a successful connection, "GSM indicator" starts blinking.
When GSM initialization finished, system will run Iridium module's initialization. If
successful, "Iridium network" indicator starts blinking.
2.2 Parameter settings
Device should set parameters before use. You can set parameters through setting tool via
device's RS232 standard serial port which also has data transparent transmission function.
Detailed setting commands see "User Communication Protocol" part in Auxiliary《SAT802
Communication Protocol.pdf》.
2.3 Working mechanism of data transparent transmission
Any data not being above-mentioned parameter format that terminal serial port received will
be considered as "user transparent transmission data", and according to channel status, data
will be sent to its destination by GPRS data link or Iridium SBD.
Bytes interval in the data packet of "user transparent transmission data" should not be larger
than 0.5 second and the length of each data packet should not be larger than 336 bytes. When
large amounts of data need to be transmitted, data will be divided into packets.
Data transmission between terminals has a data length limit with a maximum of 266 bytes.
As a response, after sending "user transparent transmission data", device then sends a "SEND
OK" message to external data device via serial port. After external data device receives this
response, it prepares to send next data packet.
In dual-mode communication, GPRS channel has priority. If condition meets < login failed or
heartbeat confirmation failed, reboot GPRS link connection, if failed, wait 30 seconds, then
again, if still failed after three times>, it will automatically switch to Iridium SBD
communication channel. In Iridium SBD communication channel mode, system still keep
booting GPRS link connection until connecting successfully, if connected, communication
mode turns to GPRS communication channel.

Turn off: sleep status, GSM does not work or GSM fault.
2.4.2 GPS status
Blinking: GPS positioned successfully.
Always light: searching signal.
Turn off: sleep status, GPS does not work or GPS fault.
2.4.3 Iridium network
Blinking: Iridium is in network service status.
Always light: Iridium is not in network service status.
Turn off: sleep status, Iridium does not work or Iridium fault.
2.4.4 Iridium sending status
Blinking: Iridium is receiving or sending data.
3 Installation Guide
3.1 Installation of SIM card
Insert the SIM card before installation of the main unit. Operation steps of which are as
follows:
1) Open the side plate of the main unit with screw driver.
2) Insert the SIM cards by directing it at the card seat.
3) Fix the side plate to the main unit, fasten the screw and secure it.
3.2 Placement of SAT802 main unit
The location for placement of the SAT802 main unit should be determined in advance. The
location should allow anti-humidity, avoidance of high-temperature area, and be far away
from magnetic field and other sensitive electronic equipment.
3.3 Installation of GPS antenna
GPS antenna must not be installed under metal baffle plate because it can hinder receipt of
GPS signals, thus affecting the normal monitoring and positioning of the SAT802 main unit.
Try to install GPS antenna as horizontally as possible. Place the convex upward, and its
included angle with the ground must not exceed 15 degrees. Besides, it must be fixed

securely.
3.4 Installation of GSM antenna
The GSM antenna will transmit RF (radio frequency) signal, in order to avoid interfering with
the unit’s equipment, the GSM antenna should be placed far from the main unit and the
multifunction cable.
3.5 Installation of Iridium antenna
Iridium antenna must not be installed under metal baffle plate because it can hinder
transmission and receipt of satellite signals. Try to install Iridium antenna as horizontally as
possible. Place the antenna upward without high buildings nearby and its included angle with
the ground must not exceed 15 degrees. Besides, it must be fixed securely and far from GSM
antenna. It is recommended that the distance between Iridium antenna and GSM antenna
should be no less than 1.5m.
Warning!: Any change of the GPS, GSM and Iridium antennas’feedback cable may affect
the normal working of the SAT802.
