I want to make a count down timer,with a K8063 display.
I may run it from a parallax stamp microcontroller, Are the two compatable?
I down loaded the software from the velleman manual for windows But I can not open it,I do not have the display from velleman yet, Will the software not open without a display attached?
Is the purpose of the software to run the display? If so do i need the PC attached at all times for the timer to count down? Or can i remove the computer once its loaded to the 8063?
And finally,the cable is it any usb to serial cable? ( or is it the velleman pcusb6) Does anyone have a wiring diagram to build or understand this cable. Thanks jon
Also if thats what the software is used for,,,is there a manual that explains how to use the program?...ie,,,where do i get the source code to test the display? It says from the web site,,,sorry i looked all over that site,,,why can a person not contact velleman, every other site has a contact tab??
Make sure you understand the following before you buy the K8063:
K8063 is a serial controlled controlled display.
It displays data in the way a computer monitor displays data.
It is a non programmable, dumb device. It needs to be connected to a device that generates the serial data, such as a PC or a microcontroller at all times.
If your parallax device can output RS232 at 2400 baud, then it can be used with the K8063.
A USB to RS232 converter should work fine with this device.

Can anyone help me find the vb6 source code? I have all over the site and can’t get it
Ok…I got it down loaded But for some reason , after the program is installed and i try to use the demo program it opens the window and quickly just closes,
yikes,am i ever having trouble,thanks kindly for your replys…
EDIT…
I can see the score board program,and the demo program im my programs list,but when i click on them,I get port error,Do i need a display attached before i can run this software?
Most likely, your PC is not equipped with a COM1 or COM2 port, hence it generates an error and closes the program.
You could check your port number, edit the source and recompile.
You can search the web and use the term “usb to serial”
You will come up with a bunch of adapters.
This will give you an idea of what you can ask for at your local electronics or computer store.

I did that…It seems its not just a pin to pin connection, but rather i the cable requires a chip in it also. Any ideas if i can build my own cable to run the display ( I suppose the old computer would come in handy now )
USB to RS232 is not just a matter of connectors, also the protocol and voltage levels are completely different.
Therefore, if you do not have a an RS232-port, you need a suitable converter.
