3-6 Vehicle speed signal installation and debugging
(1) Vehicle speed signal and speed amplifier
linked drawing:(Figure 8)
(2) Speed amplifier debugging:
The first is me asureme nt before start to debugging:
1) The speed sensor signal line will connect to the
voltage of ground when the vehicle stopped, and
when the vehicle is running too.
2) According to these two measure value and then
select the corresponding of adjustable means.
The first method: (Figure 9)
Use the multimeter to measure the vehicle speed
08
(2)SD card interface:Insert or take out the storage medium SD card.
Nose: Not allow to inset or take out the SD card when the video
recorder is working,must waiting for the host had power off just
can take out the SD card.
(3)TV out interface function: Debugging for the Procedures of manuf -
acturer
.
Don’t the TVOUT output video wire!
(4)Press the manual/auto button and shells up could shutdown when
the recorder is normal working. And now,the auto startup function
have been canceled. Re-boot must through the manual button next
time.
3-9 The function instruction of the video recorder
1. Setup the video quality and resolution
(1) Setup the quality of video
2)Through the left/right button to select
"record" according to press the "OK"
button to enter the "record" menu
interface (Figure 18).
Figure 18
3) Enter into the "record" after the menu
interface (Figure 19), use the left/right select
"AV IN" and press "OK" button to
displa
y
back screen, then press the "Menu"
button to enter the "AV IN" menu interface
(Figure 20 ); through the up/ down button to
Figure 19
4) Access to quality after the set menu (Figure
21), with the up/down button to select the
quality of the video, there are three types of
high-middle-low options, the higher the
quality of the images, the better the effect,
but the record will become a document of
great time reduced.
Figure 20
5)
the normal shutdown interface settings
have been saved, and then startup to check
whether there have set up to preserve.
(2) Setup the resolution of video
Press the "power" button off affter setup,
Figure 21
1) First insert the USB key on the host , make
the host at the manual state,,after over 2 0
seconds ,then press the "Power"button
again reboot the system,return to the
main interface

A The Yellow Wire-vehicle speed signal wire
Funtion:The speed signal line of vehicle eletronic pulse sensor.
Connection:Only connect to the electronic pulse sensor speed signal
、
B
The Orange Wire-vehicle foot-brake signal wire
Funtion:Vehicle brake light signal line(brake will have high voltage
and no brake will low voltage).
Connection:Only connect with the vehicle brake light signal line.
