Hello:

I have been working with a MOS-AL162 with several microcontroller projects for a couple of years and it works great. I have it configured for 9600Baud.

Recently I got another display for a spare - I bought a LK162 because Digikey sells them and that was handy for me.

Now here is my problem
I get gibberish on the LCD when I use the LK162, but when I connect the MOS-AL162 I get the correct text.

I have seen that there is a message about re-configuring the
baud rate with the software utility - Is that the only way?
On the MOS-AL162 there was a physical jumper you could move to select either 19200 or 9600 baud.

-Changing a jumper seems easier to me than fiddling around with other
connectors and soldering and unsoldering.

Hi Randy,

Thank you for posting on the forum.

It sounds like your LK162-12's baud rate was inadvertently changed. You will need to jump the manual override to get it back to 19200. And you are right, the only way to get it back is to re-configure it. Try sending the command 254 / 57 / 51 see page 16 of the manual. After sending this command, you may take off the manual override jump and power normally.

I understand that it is easy to use a jumper for baud selection, but we also want to offer firmware configuration option so that we can offer more than 2 baud rates. It also eliminates the need of a header, frees up real estate on the board.

I hope this helps.

Thank you and Best Regards,[/url]

I got it sorted out -
The problem was on my end - picbasic serout and serout2 are different.

I still like hardware jumpers rather than setting stuff in software though.

BTW - what are the 3 jumpers for on the RS232 area?

Good to hear you got it sorted out.

The jumpers are so we can configure the 4 pin power/data connector (and the DB9 connector) to go to the RS232 IC. With the LK162-12 we offer 232, TTL and I2C protocols.
