How to drive an X10 Firecracker (CM17A) using a RS232 module - Spider

The CM17A is a serial device that uses DTR and CTS to send the X10 commands. The RS232 module doesn’t have drivers for the DTR line. So by adding a jumper to the CM17A across pins 3 and 4 you can drive it with the TXD line. I adapted a driver written by Eddie Sheffield to use the txd line.


Thanks for sharing. +1 for a video :slight_smile:

Maybe I Have a problem on the codeshare but I Can t find any cs file…

@ andre.m -

Thanks for your perspicacity :wink:

@ LouisCpro - You can download the project and get everything.

@ andre.m - I see that also. All of the files are in the project zip file. I’m not sure why they don’t show.

@ Gus - Do you have any idea why the source files don’t show up? What did I do wrong?

Well after the third try - I removed the pdf files and now the source files show up.

Must be a bug in code viewer.

@ Architect - Is there a way to clean up this post?

What do you mean?

@ Architect - The first two uploads of the code are useless. Is there anyway of deleting them? I don’t see anything from my end.

Not that I know of, but it doesn’t matter. Look at is as a versioning system. Besides the whole thing is going to be moved soon.
