Leave the 2 jumpers in the middle. Set LCDC to 19200 baud.

Yes, you can solder/wick them off, those are components, just solder blobs.

I was told there is more to this, Tom will be posting the details and a picture of what your board should look like to completely put it in RS232.

Hi

Your board is set at TTL levels. The first picture in your last post where it says 'it may be impossible to read in the pic but it says:
SIPEX
SP232AEN
0243 '
have two pads jumpered/soldered. You need to take those solder jumps off.

Hi

The problem really sounds like wrong baud rate.

Hi David,

I have replied to you via email. Have you tried the custom characters out?

Please let me know if it works for you.

Hi David,

To get the firmware revision, please send the command:

254 / 54

the module will reply a 1 byte value.

I will prepare the character definitions for you and email you via the email in your technical support question.

Hi David, Unfortunately, I can not find a firmware revision of 3.2, could you possibly mean 2.2? If you do have firware version 2.2, medium numbers should work. Have you tried the commands I suggested? If there is a need to upgrade your units, it will need to be sent back here. The work around to th...

Hello Edward, Thank you for posting on the forum. Can you please tell me the PCB rev and the firmware version of your MX211. I am afraid that maybe it is a bit old and that we have not yet implemented medium numbers (2 row height) on it.. Large numbers are only implemented in displays with 4 or more...
