I have 2 brand new lk202-25-v and would ideally like to have one as i2c and one as TTL serial. I am just nervous about using that much heat on jumpers so small I will have trouble grabbing them. I just cant let all these displays sit here anymore if I ruin them then oh well. 10 matrix orbital displa...

I have a new display I want to turn to i2c tll communication. The jumpers are so small and when I tried to heat them up it didn't seem to work. do you think it would be ok to use side cutters and cut them off adn then unsolder the remains. They are so small.

Hello I am going to make an attempt to use this display again. I was wondering if the manual has been updated? Or is it still being downloaded from your website with incorrect information?

So my next immediate questions and concerns. 1. So what is TX and what is RX? I assume since the display hooks up via the db-9 connector fine (or used to before it was bricked) that the pin 2 on it is TX like the manual states and the pinout on the brown alternate serial header is in fact backasswar...

http://www.lcdforums.com/forums/viewtopic.php?f=1&t=3508&p=24756#p24756 OK i found this post here and it shows how you guys made another mistake on your manual, you know mixing up the TX/RX pins on the alternate serial header!!!!!!! I have confirmed that what you say is TX on the db9 connect...

Hi Marvin, Thanks for posting! While I am sorry to hear about the trouble that this has caused you, I am glad that we now have the oportunity to fix this issue so that other people may benifit, thank you for your contribution. Now all that's left for me to do is to go through the manuals and update...

I assume you dont have to have the 0 ohm jumpers if i wanted to go back to rs232 on the lk202-25 solder would be enough? If so i may just cut the jumpers off with cutters? other than that getting out a larger soldering iron an djust getting it real hot to remove it may cause damage since its so smal...

I am going to take a video of the display and put it on youtube so we can see if it can get fixed. Is there a manual for using uproject? I just tried unsoldering the rs232 jumpers on my lk202-25 and forget it i just dont see how you want us to remove the 0 ohm jumpers. So other than the devdevil do ...

so i have a new LK202-25-v rev 3 i believe should i go through with soldering the jumpers on it or just sell it off while its new.

Just to confirm i have checked all my solder connections with a MM and its all in order so i have no idea.

well the scary thing is my next display I am going to try has jumpers half the size of this one. so on page 13 when its talking about 4 jumpers can you confirm it means to solder the R jumpers and Unsolder the I jumpers. I was just confused as its not clear and my display came new with the I2c jumpe...

i have an lk162-12 rev 2.220. Part of my problem is the manual is a little unclear about all the jumpers. on page 13 under alternate serial connection it says two jumpers will have to be soldered and two removed It dosent tell which ones just has a picture of the r jumpers soldered Am i supposed t r...

I did use the jumper on the gpo's to try and put it in default mode. That didnt do anything different i get a character like a paragpah indent symbol that has a mini 4 on it. and that is about all the text it shows right now the same character over and over. I was thinking more along the lines of th...

IF YOU HAVE A LK162-12 (Rev 2.2) AND FOUND YOUR WAY HERE STOP AND DOWNLOAD A NEW MANUAL EDIT: THE MANUAL FOR LK-162-12 (Rev 2.2) WAS INCORRECT THE TX/RX PINS ON THE ALTERNATE SERIAL HEADER WERE BACKWARDS IN THE MANUAL. (RX/SCL) (TX/SDA) IS CORRECT. THEY WERE AWARE OF THIS BACK IN 2005 BUT NEVER CHA...

Hello I cant seem to find the x-board on your website. Are there different kinds? I have a 4x20 oled display that is standard hd47780 I believe. What can I do with this can I use an x-board to hook up to it and make it usb? I would then like to use lcdc with it as this is the only program I know how...

you might want to try some artic silver adhesive or some other thermal adhesive if you plan on testing them with other than air. I made another post somewhere but I am going to do the same thing you are but when I am done I will use some artic silver instead of regular epoxy. Basically I was thinkin...
