I study pameter cnc system 6B T/M.
Does anyone know if you can get cables for a USB to RS232 connection for PC to CNC connection? I did some research and see that there is a cable like that. I just wanted to know if it is possible before I buy anything. I currently have a DB9 to a DB25 and did the pinout for proper connection. If it is possible is there a different pinout for doing this vs. a standard CNC 9pin to 25 pin connection? Any downside to this? Any recommendations on were to get this would be helpful. Would RadioShack carry something like this?

charan28, what are you asking for? Do you need a pinout or parameter settings for the 6B?
I just need to know if the USB to RS232 can be successful as stated in my post.
Many people are using these converters with CNC communication. I have had mixed results and found the quality is variable as well as the driver software for them, but they are cheap and it's easy to try.
The pinout on the USB-RS232 would be exactly the same as the pinout on a standard PC 9 pin serial port. I am assuming you already have a cable that has been proven with a standard PC port connected to the CNC? If not then it is worth establishing proper communications using a PC with built in port before you add in the additional complexity of a USB converter.
In my personal experience, I have run into too many frustrations using USB-RS232 adapters. I use Ethernet-RS232 adapters on all my machines.
This is a very easy and very inexpensive item that I use. You can set your pinout how you see fit without having to worry about drivers that you need for USB stuff
DB25 to Ethernet
Thanks for the responses guys. I do currently use a DB9 to DB25 with ethernet line that I did the pinout myself on. I have never had a problem with it. I wanted to know because when I got my laptop at work here it did not have the DB9 serial port on it. I had to request one. My IT guy said that a lot of newer computers are not standard with them. I wanted one incase I am in a pinch without my laptop and I have to borrow one that does not have the serial port.
PinMan when you say you are using Ethernet to RS232 are you using a 9pin from your PC and 25pin to the CNC like the RJ45 jacks that take the ethernet between them? Or Is there a way to just go Ethernet plug on PC to RS232 on CNC??
Can you pick up the USB-RS232 connectors anywere or do you recommend a place or brand?
Thanks again guys,

Ethernet cables going to my various machines
Ethernet to DB25M Adapter (linked in previous post) for the 25pin serial ports on my machines.
We run 16 machines off one pc and 32 machines off another pc.
But if you dont need the multiports (i.e. only running one machine), you can connect the ethernet cable to your LAN and communicate with the machine that way. Just make sure that you are assigning COM1 or COM2 to your LAN connection.
Is there anyone with a detail step by step to set-up parameters in a variety of Fanuc controllers, 10M, 11M, 15M, 16M, & 160M in order to properly send/receive to our PC which is Windows XP through our DNC box. We are using a 16-Port Serial Hub or Multi-port DNC box (Spectrum CNC Technologies). We are connecting a 9DBF/RJ45 on the DNC box to a 25DBM/RJ45 to each machine.

You should probably explain what your DNC box, otherwise I think people will be unable to be very helpful.
What do you mean by "explain what your DNC box"?
Sorry, I missed a word out there.
I meant "explain what your DNC box is"
i.e. what is it? ... a switch box?, a serial port server?, a BTR device, a piece of special hardware?...
Thanks very much for your help. Does my request seem a little more understandable now?
