Hi !
I just purchased two of these from Parallax for a Basic Stamp 2sx project.
Unfortunately I can't get the display to work properly. I think it is a baud rate issue. The display lights up perfectly but when I send text only garbage appears.
I have tried all 9600 baud rates (16224, 240, 24816 and 8432) but nothing seems to work.
Any idea what the proper baud rate for the BS2sx is ?
Thanks for the help.

Thank you for your fast answer.Ray wrote:The easiest way to set the unit to known settings is put on the manual override jumper and write your prefered settings to the unit when you have restored communication with it. See the manual for details
Unfortunately no manual came with the display and I don't see any jumper on the board !?

P.S.
Number on one display is 09M06-1150
Can't get LK204-25-WB-C74 to work with BS2SX
Thanks for the URL. However, the display I have is not shown in the manual. It seems to be a special version just for the BasicStamp. There are no jumpers and no DB9 plug.
It just seems to be a baud rate issue, since the display turns on and does responds with strange characters when I send text.
Any help is greatly appreciated.

A problem with the baud rate seems like a good guess. If you connect row 5 and column 1 together on startup, either with a jumper or pressing the appropriate key on a keypad, you will enter a "Manual Override" mode. This mode will always startup with a 19,200 buad, so you should be able to communicate with it. Change the settings to a known value and restart the display again. Manual override mode doesn't change any saved EEPROM values, it just ignores the saved values temporarily.

Display works now as is with a baud rate setting of: 110
