The ground wire of a db9f needs to plug into the ground on the breadboard. The transmit line goes to pin 3 on the db9 (or you can use a active high ttl level serial signal from a 5v microcontroller on the same power supply). Start Hyperterm and set your com port to 4800 8 Odd parity and 1 stop bit Connect and you will start seeing your text on the top display. Send a ctrl/v (or a hex 16 with a micro or software) to switch to the bottom display. Hit ctrl/r (or hex 12) to switch back to the top display. Also applying 5v to pin 5 will put the device in test mode and you can see the firmware version and text on both. The default baud rate setting is 4800 8 o 1 but if you remove the solder from J3 then it is 4800 8N1 (then a basic stamp can run it) NEED TO PAUSE 100MS or longer AFTER THESE COMMANDS! '$12 goes to top display '$16 goes to bottom display '$17 throws 2 bytes away from the next text string?? '$19 the next byte is ??? like a t = omega??
