I recently ordered a LK162-12-WB lcd and im having trouble displaying the correct char's. Im using a ethernet i/o to send it data which supports ttl votages so i put the jumpers on ttl but i dont know a lot about rs232 ive been looking on rs232 info websites but i want to make sure this is correct.

to send this display ascii "A" with rs232 with ttl voltage i would use
one start bit and two stop bits correct?

1=ttl low 0=ttl high right?

it should look like this right?

start info stop
0 01000001 11

or like this?
start info parity stop
0 1000001 0 11


any help will be apreciated



rs232 site i was lookin at

Hi legendsngray,

'A' sent in serial (TTL) is:

0 10000010 1 (the second one you had)

thanks man ill try that

that didnt work man but it may be something with the speed

the i/o controler can do 500,000 changes per second so what baud would that be?


all its doing is showing one of the factory custom char's now

Hi legendsngray,

The default baud rate is 19200. To make sure that your module is at 19200,
you can put a manual override jump: please see page 11, Figure 17 of

Btw, I am a gal.

hehe, i was wondering when she is gona make it clear that she is not a Man

so "darlin" (<--from tx so no g) if i was using a I2C bus i would need to have the

controller

then a resister to 5v power for the data wire as well as a a resister to 5v power for the clock wire

then multiple lcds

then a resister to 5v power for the data wire as well as a a resister to 5v power for the clock wire

correct?

Hi legendsngray,

Yes, if you will be using I2C for communication with the displays, you need to put pull-up resistors on the SCL and SDA lines. You need to put only 1 pair of these resistors, not for each module that you will be connecting.

but one pair on each end of the bus right?

Hi,

One pair of resistors for the whole bus; although there are pads for pull up resistors on the module, it is best to put them with the host microcontroller.

ok thanks

YAY got it workin!!

question though:
how long would a large order of about 55 of these display's take to get processed?

maybe alittle while before the order is placed but need a time table

Hi,

Sorry took long to answer your question. I will forward it to Sales.
Thank you for your interest.

legendsngray,
