Fanuc o3p controller rs232

[kluppy]

hi everyone, sorry if this is a repeat question but i have just bought an Amada Aries 222 with a fanuc o3p controller. i would like to communicate with this machine via an rs232 cable and i was wondering if any of you would have a pin out diagram? i know it would be easier to buy a cable but ill be honest with you, i can get the bits for nothing at work and i thought it would be a good exercise to make one. any assistance would be greatly appreciated.

thanks.

This works for me:

DB25M (CNC) <------------> DB9F (PC)

1 <---------(SHIELD)--------- No Connection
2 <--------------------------> 2
3 <--------------------------> 3
7 <--------------------------> 5
4 & 5 jumped CNC end only
6, 8, 20 jumped CNC end only

great!! thanks, i'll give it a try

ok, so i've made the lead, belled it out and it's all cool. i connected the machine and the computer. adjusted my DNC settings on the computer to 9600, even, 7, 2, iso, iso, Xon Xoff. but it doesn't seem to work properly. when i load into the machine it sends the first 2 lines of the program and throws an error. when i suck a program out of the machine it says the the file transfer is complete but when i open the file there is nothing in there. can anyone help me??

You will find pinouts to suit Fanuc in the FAQ of my website - url below

What error are you getting? If the cable has been made in accordance with the configuration described by Dave and machine parameters are set correctly, with the PC software setting set to match, then you should have no problems.

Purchase a RS232 tester from an electronics store and place it inline with the cable connection. Try sending a program from the machine to the PC and look for activity on the pin 2 led from the machine. If there is activity and you get nothing at the PC, its probable that the PC software is incorrectly configured.

thanks guys, yeah i need to figure out how to check the machine settings. any hints?

To work with xon/xoff I think you will find you need the following links in th 9 pin D type (not shown in the pin out supplied by Dave)

link pins 7 and 8 on 9pin D type (CTS - RTS)

link pins 1, 4 and 6 on 9pin D type

do i need to have xon/xoff enabled?? in case you guys haven't picked up on it i'm a bit of a novice with this stuff. if you can recommend what settings i should be using i'm more then happy to listen.

The pin out you have been provided with is for software handshaking (xon/xoff) hence all the control signals are linked out.

I am not familiar with the 03P control therefore I can not advice you on control parameter setting.

Your PC software must be set to xon/xoff for it to work with this cable pin out.

If you are unsure if you PC software is working correctly you could download the evaluation version of EditComm from my website for test purposes - url below

Kluppy,
Just use the cable configuration exactly as suggested by Dave in Post #2. For Xon Xoff handshaking you only need to have the hardware pins at the machine end bridged to keep the machine's uart happy. Make sure you have the machine control parameter set to use DC1 to DC4 characters (software handshake characters).

Post the error that you're getting when sending data to the machine; it will be easier to help you if we know what the problem is.

Bill

Surely it would be better to link out CTS, RTS, DSR, DCD & DTR at the PC end as well ?

The control signals on the PC end can not cause problems then ?
