Touch Interface

with universal video converter _V100709

This interface can converter touch panel signals into DVD /TV IR signals, or iPod control signal, so when people watch

DVD inside a car, he does not need a remote controller any more. This interface can also be programmed to a new Remote

controller in the installation process. The various versatile video conversion inside makes this interface suitable for

almost every car which has a video or RGB input.

The main features are:

1. People can enjoy DVD or video source without remote controller while dirct touching the icons on top of the

screen.Dedicated icons are mixed inside the video stream for easy

read and touch operations.

2. Several video source can added onto a single screen without

added extra keypad to select them.

3. This interface has a programing function which allows a new

remote controller to be recorded.

4. This is a an upgrade version from Navlinkz FV-02 and FV-09

video converter which haven been sold for several years, it is very

versatile and easy for installers in video conversion purposes while

installed in almost whatever car which has a video or RGB input connector, and it can handle almost all video

input[NTSC,PAL,SECAM, in CVBS or RGB], while offer a very stable standard video output.

5. Multi-point touch screen calibration algorithm inside makes this interface can be installed with almost every

screen, no matter original touch screen or added.

Note：

(1) Video is memorized into 64M SDRAM first, then read out and encoded back into video, to guarantee that

output is always fixed into one stable format, no matter what the input is although the input and output are

showing the same video picture.

The input can be: NTSC，PAL，SECAM, VGA，in RGB or CVBS format，the PAL/NTSC/SECAM inputs are

automatically detected and processed.

The output can be : PAL，NTSC，VGA，RGB in RGB or CVBS format. the PAL/NTSC,CVBS/RGB/VGA output are

selected by DIP switch.

(2) the Navi RGB and AV input signals from the input side are digitized into 800XRGBX48 0high definition signals

first, then recoded from the memory tank to generate RGB or AV signals again.

6 When DIP6=ON, this interface go to IR program

mode to record the new ir code. Refer to “Ir

programming” part for details.

When DIP6 goes to ON/off 6 times, this interface

go to touch calibration mode to get tuned to a new

touch panel. Refer to “touch calibration” part for

details.

Set to “OFF” for normal use.

The up row is RGB output，the below row is RGB input，see below for

details

The 2 jacks are: SOG ouput[sync on Green] and CVBS output。

The CVBS can be connected to the video input of a monitor directly.

This 8-pin connector is used to connect the touch daughter board, it is not necessary for the installers to use it

usually, but it maight be helpful to the installers.

will halt the CPU inside. Leave it open for normal use. clock bus for touch screen.

Pin 7 This pin=5V output voltage when in inserted

video mode, when in original car video

mode, this pin=0V.

5. key buttons

The input box has 3 side keys, the installer may use it to tune the picture display, and touch function for the

connected DVD or other devices. The 3 keys are : menu, +, -.

When menu key pressed 1st time: the left OSD options will be shown,

when pressed 2nd time: the right OSD options will be shown,

when pressed 3rd time, the osd window will disappear.

The user may use the +/- key to go to the edit mode of each item, and use menu-key again to go down to

the next item.

The DVD, TUNER,NAVI items mean the IR output of RGB,AV1,AV2 input respectively, there are already

many types of DVD, TV tuner and NAVI brands programmed inside.

The installer may also set it to be “PROG” if the video source brand is not listed inside. Then he may pull the

DIP6 DIP down to program the IR code.

The installer may also set it to be “NONE” if he does not want the icons to pop out when people control it.

In this case, the user may still touch the left-top corner[‘power’ icon] to tuner off the device, and he may

also use the left-button corner, [‘SRC’ icon ] to switch the input.

The H POS, V POS items mean the image location on monitor, different video players like DVDs may send out

video with different amplitude, different image location although it is PAL or NTSC. These 2 options will give

the installer the convenience of adjusting image perfectly centered in a couple of seconds.

The ”Amplitude”is used to set the video output amplitude, a normal monitor needs 0.7V~1V for normal

display on 75 ohm impedance monitor, but some needs higher[ for example BMW and Nissan which has sync

on Green need 1.2Vpp for brilliant video display otherwise picture looks like washed]. Higher video

amplitude is also better for noise immunity and more vivid display , but too much high amplitude(>80) is not

suggested. The default Amplitude =50, video output=1Vpp；whenAmplitude =80，video output=1.5Vpp；

when Amplitude =10, video output=0.5Vpp. [ when monitor’s input impedance=75 ohm.].

The CAR VIDEO option is can be set to be “YES” or “NO”,

when set to “YES”, the CAR RGB or video input is shown when the user is switching the input.

It is switching like this[when DIP78 set the output to be RGBS]:

car RGB converted RGB from AV1 converted RGB from AV2… car RGB

Or [when DIP78 set the output to be CVBS]: car CVBSconverted CVBS from AV1 converted CVBS

from AV2 car CVBS

[note: when the Car RGB wires are used for CVBS, just connect the CVBS to the red wire, and leave G, B,

and Sync alone.]

when set to “NO”, the CAR RGB is never shown.

This is for monitors which has already a RGB or CVBS input.

They need such an interface for touch control onto DVD or Tuner.

A. IR learn operations

The input box has separate memory space to remember the IR code of every input[RGB

input,AV1(DVD),AV2(Tuner or iPod)].

1) When the current input channel’s IR output is set to “PROG”, the input box goes into IR learn mode

when the DIP6 is pulled down to ‘ON’ state.

2) Then one icon will be blinking, saying that one IR key press is

needed, the installer need to point the remote controller

toward the whole on RGB input.

3) When one code is learned, another icon will be blinking, saying

that another IR code is needed. The installer then repeating

step 2), until all codes are programmed. Then the icons

disappear automatically and the installer may start normal

operation.

the touch screen will not acknowledge touch screen operations when it is in programming mode, except the

‘SRC’ key, which will terminate the learning progress.

B. IR code out for video source devices

The input box can output the IR code in a 4-byte protocol which most of AV devices use today, the output can be

2 ways:

(1) wire connect way without carrier frequency, or

(2) wireless way with carrier frequency.

The difference is: the wireless way says the signal ‘1’ with 38K frequency

pulses while the wire way says by just voltage.

The input box has 2 IR output pins: IR-RGB(the 6th pin of RGB input), and

IR_DVD(the 7th pin of RGB input).

The IR_RGB is always in wire-connect way without carrier, while the IR-DVD pin is in a wireless way

The IR_RGB and IR_DVD send the IR code out no matter the monitor is showing video in RGB,AV1,and AV2.

The video source may receive all these IR codes, but they will choose to acknowledge because the data bytes

values are different.[the 4 data bytes say the device by the first 2, and 3rd byte says the key value, the last one is

the verification]

C.Touch panel calibration

When the DIP6 is pulled down to ‘ON’ 5 times repeatedly, the monitor goes

into touch screen calibration mode, a cross will be shown on screen, and the

installer need to use something like a pencil to hit the cross, the cross will be

changed to another location after one point is recorded.

This multi-point calibration should be done by the installer at least once, since

all touch panels have different physical resistance and capacitance. The calibration

guarantees the end-user have nice touch feelings.

Flexible touch panel

this touch panel offers no thickness, which is ideal

for cars which has original LCD screen, because

they do not offer extra space for touch screen.

Video noise filter:

Sometimes noise may be generated if the video devices

are too much far away separated or engine noise

influences, this noise filter can remove many kinds of

video noises easily.

Application Examples:

1. Add touch control functions to DVD,TV and get free from remote controllers.

Enable AV1 by DIP, if necessay, enable AV2 and navi RGB also to get some extra inputs.

When power on, the unit will automatically go to the first DIP-enabled input.(AV1 here)

The user may switch the input by touch the “SRC ” icon on screen.

The CAR VIDEO option should be set to NO

When DIP7 and 8 are both OFF, the output is NTSC-composite[no matter the input is PAL,NTSC or SECAM or RGB],

the big internal memory tank and high quality scaler guarantees there is no picture quanlity decrease.

When DIP7 is OFF and DIP8 is ON, the output is PAL composite. [no matter the input is PAL,NTSC or SECAM or

RGB].

2. Convert RGB high definition videos into composite（CVBS）video for monitors.

Enable RGB by DIP, if necessay, enable AV1 also to get one extra input.

When power on, the unit will automatically go to the first DIP-enabled input.[navi-RGB

here]

When DIP7 and 8 are both OFF, the output is NTSC-composite[no matter the input is

PAL,NTSC or SECAM or RGB], the big internal memory tank and high quality scaler guarantees there is no picture

quanlity decrease. When DIP7 is OFF and DIP8 is ON, the output is PAL composite.

When DIP4 is set to ON,the input is RGB-VGA from computer, that is （800X600·60Hz）, when the DIP4 is set to

Video in， video out

IR out

RGBin， CVBS out

IR Out

OFF, the input is RGB-NTSC for navi computer, which is vertically 240 lines(or 234 lines),horizontally 320,400,or

480 pixels.

3. Add extra video inputs to monitors which already has RGB input. For example: Volkswagen MFD2,Mercedes

W211/W220, Toyota, Ford(before year 2010). This monitors already has RGB input.( atten: W211，W220 needs

Hsync,Vsync split signals]

DIP for AV1，AV2 are enabled by DIP, according to the video devices that are installed.

DIP 7 and 8 should be set to (on,off)： output =RGB-NTSC component video.

The CAR VIDEO option should be set to YES so when switching, the input are

shown:car RGBAV1AV2 car RGB… if set to “NO”, the car video will not be

shown.

When DIP 7 and 8 are set to (on,off), the screen always starts at showing car RGB when start working.

4. Add extra video inputs to monitors which needs RGB input,but need sync on Green[that is SOG]. For example, BMW x5

before 2008, nissan 2010 and older versions, Renault, and American Pathfinder.

DIP for AV1，AV2 are enabled by DIP, according to the video devices that are installed.

DIP 7 and 8 should be set to (on,off)： output =RGB-NTSC component video. when switching,

the input are shown:car RGBAV1AV2 car RGB

The Green signal output wire should be re-wired to the 2-pin Jack near the RGB-wires, that one always has sync on

green.

the screen always starts at showing car RGB when start working.

5. Add DVD,TV tuner or other video devices with touch control function for Mercedes W212, Citroen-C5,

Audi-MMI,Buick/Opel, and many other cars which has already a monitor.

NAVLINKZ has video interfaces for these car, they have internal touch icon generations already, in this case, the

installers just put one extra touch film on top of the screen, and they can use the interface to control DVD or other

video sources.

Almost all Navlinkz’s interface use CAN bus decoding and GMLAN decoding, so the the users do not need to

stick any extra key to switch,people use original keys to switch, and they may also use origianl keys to pop out the

DVD touch icons.

The installers can also use the touch interface between the video source and interface, using the touch

interface’s video-in-video-out function and get the touch function for extra video device.
