How do I set up the LED to receive ASCII strings? What I send is visible in the motor's software, but gets garbled up in the display.
Any help is greatly appreciated.

output from the motor at pin 10, which is the RS-232 transmit channelI guess that's the motor's pin 10?
Note that the RX input should be a 5V TTL-level signal directly from a 5V microcontroller or other 5V system. You should NOT connect the board to RS232-level voltages, which are +/-10V and will damage the board (see our explanation here). If you do wish to connect this display to RS232 signals, you can use a level-shifting board such as our PRT-00449 to translate the RS232 signals to TTL-level signals.that could be affecting things.
