One of our buyers sent us the following information
We found it helpful, perhaps you will, as well
The device needs a 7805 or equivalent voltage regulated power supply of 5v. 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?? '$11 then $0A blanks ?(disabled) top display '$11 then $01 = clear dosplay and goto home on top display '$11 then $04 = clear top and write backwards scrolling! '$11 then $07 = clear top and write backwards scrolling! '$11 then $0F = blinking cursor on top display $11 then $13 = top backspace cursor one space (leaves characters) need to do a $12 before writing over chars.... $11 then $1D = displays on top display "SPECIAL MESSAGE" whatever that means. $11 then &1f = shift top text one space to right $11 then $80 goes home, but does not clear. on top display '$15 then $0A blanks ?(disabled) bottom display
