I have found at work some old led message scrolling signs that were used on a shop we use to have. they power up alright the problem is that the connection that you connect to the computer it is a rj12 connector like the phone line connection over here in australia. I need to know where or if there is a diagrame of how i can use the rj12 conction and make on the other end a 9 pin serial connection to hook into the back of my pc .
it is a signatronics led message sign serial number 98895
if anyone can help me with this it would be nice
thanks
