DL104PC----10.4“ all in one pc

1. The model DL104PC is an interesting product for me, can you supply this model for me with:  

- Support 1024MB DDR400 RAM-------This is OK,you need add more USD43.

- Support 160GB HDD-------This is OK, you need add more USD75.

- 1 x TV-out-------This is OK.

- 1 x 100/10MBps Ethernet LAN -------This is OK.

- DVD player -------At present, we can not make the DVD player, if that, we need to amend some moulds, moreover if your order quantity is over 200pcs, then we can amend the moulds for you for free. 

What are the costs of this model? ------- This unit price is USD500(our standard config)

Can you send me the instruction manual by mail? -------Sorry that we have not the instruction manual of this product as it is a new developed products, but we have instruction manual of Mainboard in Chinese version, without the English version mainboard instruction manual. Sorry for that. If you need the Chinese version instruncion manual,pls let me know.


2.10.4 inch all-in-one sample with the following spec's:

- 1024 x 796 resolution touch screen-------I think it was clerical error, in fact it should be 1024*768 resolution, right? :) If so, you need add USD25 for the 1024 x 768 resolution screen.

- GPRS modem with external antenna-------OK, you need add USD65 for the GPRS.

- Bluetooth-------OK,  the function is for free.

- 1GB memory-------OK, as our standard config is 512MB, so if you need 1GB memory, then need add USD30.

- The most powerful CPU within the current board I got from you (now 1.1 Ghz Pentium mobile, only if possible, please increase)

 -------OK, we use the 1.1 Ghz Pentium mobile you got from us. At present, we only can be use the 1.1Ghz Pentium mobile CPU to do this model, because this mainboard only can be up to 1.1Ghz CPU, if use more powerful CPU, then it release a mass of power and heat, that would be lead the PC can not work as usual, so you need the powerful CPU(eg: duo core 1.5Ghz), we need change to another project.

- Flashdisk 4 Gb including window s XP cop

-------OK, you need add the USD45.  By the way, if you use 4GB CF card, then you needn't use 80GB HDD, right? if so, that would be reduce USD45. 

Pls kindly confirm if you need not 80GB HDD, only use  4GB CF card


3. Q: (DL104PC) We wish to change the OS to "Ubuntu" (Linux). To do this, we had to go into CMOS setup and change the boot sequence to CDROM, where the install disk for Ubuntu is. After we tried this, the LCD is not correct, meaning there is 3" of black screen on the right, and the display is very distorted. Is there a 'RESET' button for the monitor, or some way to set the monitor back to factory specs?

R:   Pls see the below steps to set DL104PC back to factory specs:

       When you start the pc, press " delete" button, go into CMOS;

then press " F9" , " enter " ;

then press " F10 " , " enter ".

4. Q:(DL104PC)we just need the corners sanded or grinded down slightly to make not so shar p, before anodizing.

---------- The corners can be made smooth. The front bezel will be slightly thicker and cannot be oxidation. We have made 15" PC like this, pls refer to the enclosed picture.

It is better to make some units at one time, not only one unit, or else the bezel manufacturer will charge extra fee.

We suggest next time when your client order more units, we make it smooth.

We will need to modify the mechanical drawing, before we start production, we will send you drawing for confirmation.

5. (DL104PC) We need a volume control for the unit, that is external, so that user can control volume. What is the lead time and cost difference for this?

------- Yes, we can do it.

We need the power to be always on, with no external power button. Is that possible, and what is the lead time and cost difference for this?

-------- Yes, we can do it. That is, the unit will automatically start to work when plug power in.

Just to make sure we can get the additional heat vent holes on the top of the unit on future orders.

------- Yes, we can do it.


All the requirements needs to re-design the bezel and pcb board. The total fee is about US$1000. It will take 5 weeks to finish the design and one sample. The unit price will add US$5.

DL080PC---8“Headrest all in one car pc

1.I would like to your 8” headrest touch screen car pc with WINCE5? Pls give us solution.

-------After checked with our engineer, we can not use WINDOW CE solution to do the 8" headrest PC, because in the WINDOW CE, the advertisement can not be support Touch function, so we need use another PC solution(like WINDOW XP), then it can be touched on advertisement mode in WINDOW XP, we would use N270 mainboard to do this PC. Otherwise, we just provide the hardware, we can not provide the software of advertisement at present, so you need write the advertisement software in our WINDOW XP system by yourself, then you can play advertisement in WINDOW XP system and with touch function.

Headrest car pc / taxi kiosk /taxi touch multimedia player

1.for 10.4" headrest pc

questions: if we can build in 3G module in headrest pc?

answer: the 3G can build in headrest pc, but it is not convenient you insert SIM card, so our engineer suggest you use the external USB 3G, it is very convenient to insert the SIM card.


2.For 10.4" headrest monitor

Questions: Can you make the two poles distance is 10cm~20cm?

Answer: Yes, we can special customized the distance is 10cm~20cm for you, but you need pay us USD500 R&D fee, we would return the R&D fee to you after you place a mass order.


3. Q: Can the leather supplier put our “REVOSYS” logo on the leather? Maybe at the top right of headrest PC? The color of font should be RED. Maybe they can stich the logo?

A: Our purchase dept. ask our headrest supplier, it is difficult to print/stich the logo on the leather, so we suggest you print the logo on the front metal case.

4. Problem 1:

Fan noise is still the biggest problem. I recommend that you focus your largest effort in this area because they are currently not very suitable for cab use.



The course of Fan noise is current.the current is big,so you should to low the current.you can series the two fans.like the pictures showed.



USB is finicky. Sometime it will work, sometimes it won't. I believe it may be due to a voltage/power issue. Please test the USB hubs in detail before shipping any more units. Make sure you fill both hubs when testing. This is potentially a major problem for me because our 3g internet hooks up to USB and sometimes it doesn't initialize!



The course of the USB finicky is the unsteady current or lower current (power).To solve this problem you should supply power to the USB port to confirm enough current or power.There two ways .

First find the USB model in the mainboard,like the next picture show.

One ways is to add a stand capacitance between the USB 5v pole and the GND pole,like the follow picture shows.


Another way is to add 5V power to the USB port.that means supply 5V power to the USB port directly.find one 5V power port ,then connect to the USB model’s 5V pole,that will be OK.

Like the following picture shows.

Problem 3: Another major problem seems to be with the v ideo card and/or monitor. 5 out 10 PCs have this issue. When I load the Nvidia display drivers the display reverts to 4bit color. I can 'force' the monitor to show 32 bit color but it is at a 70hz refresh rate (not native 60hz) and it looks quite bad when trying to read any words. I followed the exact same procedures when in installing the drivers on all PCs and all are running window s xp pro. I believe it may be an issue with the display. Do all of the units use the same display?





   For the screen ,may be is that you install an unsuitable driver,you should install the driver that we send to you.


5, Q:For 10.4"headrest pc, please eliminate this 45 second delay that your engineer made. After desktop, we have to wait 45 seconds for WiFi/Bluetooth, etc to activate,please change this to much less time!

A: I checked with software engineer, when you turn on the headrest PC, after into desktop, you can find the WIFI immediately, no need wait 45s, but the bluetooth need to wait about 45s~60s then be found.


Engineer said we can not change the bluetooth delay shorter than now, because if we change the bluetooth delay shorter, that would be block you find the camera or series ports or others(that means the bluetooth would be collide with other devices and block others devices be found), so we MUST set the bluetooth delay about 45s-60s, if not, when the headrest PC turn on, you cannot find the camera or series port or others.

DL150PC fanless

1.DL150PC-----all in one pc

The hole I now see is the back end of the hole used for the VESA brackets. As it is not a blind hole but straight through if the VESA bracket screws are longer than about 5mm allowed in the design (the ones with the bracket are 10mm)   (yes not really long enough, should use the posts like for the motherboard) then when tightened down then the screw goes straight through the controller board for the HDD breaking it.


------- for your problem that the HDD needs to be lifted (which would also save any issue of swarf from the drilling catching and shorting the HDD and would also stop the need for an insulator).

DL190A----19 Touchscreen open frame LCD montior


1. We have bought 19 inch open frame monitor with 5 wire. We installed the touch driver to calibrate the touchscreen via a computer (window s xp). At this point the touch screen worked well. Now we uninstalled the monitor from the computer and installed it onto our gaming system. The monitor worked but the touchsceen did not. Our game works off an Integrated Circuit (IC) Board and therefore no way for us to install the touch driver on the system.


-------I have consulted our engineer. I am sorry our touch function only can be used when it is connected with computer.For the gaming system, the touch driver has written on the IC board when you buy this gaming system. .But this touch drive doesn't has effect for our touch..




DL220A----LCD touch screen monitor


Thank you for you reply i am interested in 22" LCD advertising board for me to run this behind the car what i need to attach to the monitor. I have some ideas to attached it behind the car and i am sure it will work this way how many advert put this machine? What is the best way to make this working with the car?




---- I just discussed with our engineer about your advert monitor. The product you said is a advertisement monitor, You can use USB2.0,CF or SD card for the advertisement.it can suppoet usual ve dio Format ,like AVI,RMVB,RM etc..


We can design a mount that you can install the monitor in the back or the side of you motorcycle.








1. Can you pls help me look for 7”/8” touch screen monitor brightness is 1000:1?


-------After checked with our engineer, there is no 1000 brightness monitor for small size, usually big side monitor(eg: 15”/17”/19”22”….) can up to 1000 brightness.


2. Remember we talked about 9" 16:9 touchscreens? You knew some other suppliers of this?


-------I would help you to look for 9" 16:9 touchscreens in China markets, and tell you the result.


Also you should REALLY consider to make some 8" 16:9 touchscreens! Only one single manufacturer have this at present.... 90% of my sale is for Lilliput's 8" 16:9 touch.... This can be fittet to almost every car with 2DIN slot and is VERY popular.


------thanks for your so great suggestion, I would submit your good idea to our manager and engineer and  b o s s.
