rs232 cable

[Dar]

as most of you know i don,t know what im doing most of the time, but i,ll keep blundering along. i need to make a rs232 cable but the diagram in the book goes from a 25 pin to a 25 pin so how do i do it with a 25 pin on the bpr2c3 with heidenhaintnc145 to a pc witha 9 pin plug. i,ll try anything and i would appreciate any help
thanks Dar
ps just a funny story. i scrapped a job the other day and couldn,t do it after 2 more trys. my wife thin told me she knew what was wrong with me.
i told her after 49 years togeather she should have a list. she then showed me something i had not noticed. i had a ceiling fan runningunder a 4ft 4 tube light. with the position of my new mill it was right over head and acting like a strobe light. it really screwed up my head. so then the worst happened [i had to tell her she was right] woo is me

Good of you to provide the pic.....It is too small to view...even after enlarged....could you copy and paste the full sized pick (not the thumbnail) or instruct me if I,m doing something wrong in trying to view it....Thanks

Just a small warning, don't ground both ends of the cable, ok to do one end, it helps with the sheilding, but if you do both ends IT MAY blow a board in the control

I have complete cable and software setup for communicating via 232 that i bought off ebay and never used.
I'd sell for $40 Canadian

You can also order a 25 ft cable with DB9 for PC to DB25 for CNC, any make / model off our website for $37.50.

Longer lengths are available and if you want to make it yourself, we have some wiring diagrams and recommended raw cable on our site.
