Safety maintenance:
It should avoid the humidity and extreme temperature when being used.
Please maintain your system properly to make sure its service life and reduce
the damage risk.
Avoid prolonged exposure of the unit to direct sunlight or strong ultraviolet
light.
Do not drop the unit or let it be in any place with severe shock / vibration.
Please avoid the collision as the LCD screen is very easy to be scratched. Do
not use any sharp object to touch the screen.
To clean the outside fuselage, please turn off the power, unplug the power
cord, scrub / wipe with slightly damp soft cloth. When cleaning the screen, please
wipe with the lint free soft cloth.
Never attempt to disassemble or repair the machine, otherwise the unit may
be damaged.
Do not place your unit or accessories together with other flammable liquids,
gases, or other explosive materials, to avoid danger.
Please unplug the power plug and remove the built-in battery if long-term no-
use, or thunder weat

3.2 CAN BUS Interface
adb command:
Set the bitrate ( baud rate ) before all operations
Example: Set the bitrate of the can0 interface to 125kbps:
# ip link set can0 up type can bitrate 125000
Quick test
Once the driver is installed and the bitrate is set, the CAN interface has to be started
like a standard net interface:
# ifconfig can0 up
and can be stopped like that:
# ifconfig can0 down
The socketCAN version can be retrieved this way:
# cat /proc/net/can/version
The socketCAN statistics can be retrieved this way:
# cat /proc/net/can/stats
3.3 GPIO Interface
1. GPIO interface as shown below,

13
2. How to read or set the value of the gpio
GPIO0~7 (IO number)
a)When the software configures the IO port as input, (Negative trigger).
Configuration command: gpiocontrol read [gpio number]
For example: Setting gpio 0 as the input state, and read the input level
diamond:/ # gpiocontrol read 0
diamond:/ #
Trigger voltage: The logic level is ‘0’, 0~1.5V.
Non-trigger voltage: The logic level is ‘1’, the input IO is floating, or beyond 2.5V, but
the maximum input voltage must be less than 50V.
b)When the software configures the IO port as output, it is an open-drain output.
Configuration command: gpiocontrol [gpio number] set [output state]
For example: Set gpio 0 as output state and output high level
diamond:/ # gpiocontrol 0 set 1
diamond:/ #
When the output IO is enabled, the logic level is ‘0’, and the IO voltage is less than
1.5V.

14
When the output IO is disabled, the logic level is ‘1’, and the rated voltage of the IO
must be less than 50V.
3.4 ACC Setting Path
ACC settings located in ACC Settings under the category of System in the Settings of
Android OS. Please refer to Figure 3-1, 3-2 and 3-3:

screen, close the screen and shut down.
Mark 2: The switch of close screen function controlled by ACC.
Mark 3: Click to pop-up dialog box as shown in Figure 3-5, to edit the screen off delay
time after ACC outage.
Mark 4: The current screen off delay time after ACC outage.
Mark 5: The switch of Trigger to shut down function by ACC outage.
Mark 6: Click to pop-up dialog box as shown in Figure 3-6, to edit the shut down delay
time after ACC outage.
Mark 7: The current shut down delay time after ACC outage.

4. Meory Card Instructions
The memory card and the card slot on the device are precision electronic
components. Please align to the position accurately when inserting the memory
card into the card slot to avoid of damage. Please slightly push the upper edge of
the card to loosen it when removing the memory card, then pull it out.
It is normal when the memory card getting hot after long time working.
The data stored on the memory card may be damaged if the card is not used
correctly, even the power is cut off or the card is pulled out when reading data.
Please store the memory card in packing box or bag if not used for a long
time.
Do NOT insert the memory card by force to avoid of damage.
