Having trouble getting serial connection to work from laptop to control. Laptop has no serial port so I purchased a usb to 9 pin serial RS232 adaptor. I am using another cable/adaptor to get from 9 pin to the 25 pin on the cabinet. I have tried both standard serial cables and rs232 cables. No Luck. Have any of you run into this?

Should I ditch this idea and get a network card for the haas control?

Thanks in advance for your assistance.

How is the 9-25 cable/adaptor wired?

You should have:

DB25 <-------> DB9

2 <-------------> 2
3 <-------------> 3
7 <-------------> 5

Since your handshake is set to XON/XOFF you don't need any more than that. You can check it with an ohmmeter or an RS232 serial tester.

Thanks,

I know with just a serial rs232 cable it is pretty easy setup.
Thanks for the pinout configuration. I think my problem lies with the usb to 9pin adaptor. I have a newer laptop with no serial port. How can I check to see if the adaptor mimicks a standard 9 pin serial port? I can ring out the cable but i dont know enough to check the adaptor.

Post the manufacturer's part number and we can look up the wiring diagram on it.

Also, just to make sure... Have you read the manual for the RS-232 communications?

[gkmotzart]

Ken,

Iogear GUC232A

IOGEAR - GUC232A - USB to Serial RS-232 Adapter

USB to 9 pin adaptor

I have read the book on the rs232 communications.

If I had a standard computer with a serial port would I be using a standard rs232 9 to 25 pin cable? Or a null modem cable? I guess I just need to check the pin outs on my cables.


Thanks,

Kim

I spent 30 seconds looking for the diagram for that cable and I could not find it. Let's assume that it is the standard 9-pin connection. There is a pin diagram here: http://www.cnczone.com/forums/blogs/...-232_help.html

You can checkout the 9-25 adapter and make sure that is correct.

Well the saga continues.

I have 4 cables. I checked the pinouts on all and found one that has the send/receive pin2-3 & pin3-2. It also has the 5-7 pin. This is a 9-25pin cable. So according to what all of you are saying I have the correct cable.

I decided to delete/uninstall the Iogear driver for the 9 pin to usb adaptor. I rebooted and reinstalled it. I left the settings on the port as the default. I did this because last time I set the port up to match the gibbs and the haas control settings.

Does not work. I think my next attempt is to use my older laptop with a serial port to see if I can send the file with this cable. If it works it is obviously this p.o.s. adaptor.

Thanks you for all for the information. I will follow up with how I make out.

Kim

[KenFoulks]

I will follow up with how I make out.

Any luck? What operating system are you using? Have you tried using Hyper Terminal? Do you have access to a proven cable?

[gkmotzart]

Not really. We have confirmed that the 9-25 pin rs232 cable is correct. We have also confirmed that the usb/9pin adaptor is a p.o.s. It does not work an when checking into it further we found that there are many complaints on the iogear adaptor with regards to its win 7 driver. I am using win 7 64 bit. Next step is to return the adaptor and ge a different brand that is win 7 64 bit certified. I will let you know what I find.

Thanks,

Kim

So you're saying 2 and 3 are crossed? This won't work. On a 9-25 they go straight through 2-2 and 3-3.

[gkmotzart]

Hmmm. I will be back by the cable in a few hours and I will confirm again what I have.

Thanks!

[gkmotzart]

Well I guess my cable is no good as well. Pin 2 and 3 have continuity in both directions. In the haas documentation I may have been looking at the db25 to db25 cable pinout in which pin 2 & 3 are twisted.

Thanks for the catch.

I am going to try to find an adaptor (win 7 64 bit) and the proper cable. Thanks all for the help. I will let you know how I make out.

Kim

[gkmotzart]

Is this cable readily available? I have checked rs232 cables and modem cables and they have the pin 2-3 & 3-2. Is this a cable that I need to have custom made?

Thanks,

Kim

[gkmotzart]

I think it may be this null modem cable.

Kim

[KenFoulks]

I think it may be this null modem cable.

That looks correct, It matches the diagram I posted earlier.

Dcoupar,

He is saying his USB to Serial adapter is a P.O.S!!!!!

I think if you search USB to serial adapters in the forum you will see hundreds of others that complain they don't work! We are talking Windows 7 now, 32bit and 64 bit operating system and the vendors of these devices have ported their code over from Window 2000/XP into these operating systems and call it supported! Well, one clue is where they are being sold from, websites that sell computer parts and probably never talked to a machine tool (or have a clue what one is). If the unit is less than $100 bucks and can't talk to the machine tool vendor or DNC company about the device, it's probably garbage.
I just posted about a Fadal DNC issue starving a machine because the USB to serial adapter. Last week, a call from a customer in MD who had a Mitsubishi who sent to the machine 1 time and then it stops. Reboot, try again, no luck, different comm port each time and the software was fine. It's the device!

If you need more help on this topic, let me know as I am happy to try to resolve!

Greg,

I understood what he said about the P.O.S. USB adapter, but he also said: "Well I guess my cable is no good as well. Pin 2 and 3 have continuity in both directions. In the haas documentation I may have been looking at the db25 to db25 cable pinout in which pin 2 & 3 are twisted."

So, it looks to me as if he has two problems.

[gkmotzart]

Sorry I have not been back in a while.

I had to completely give up on the usb to serial adaptor. After 4 different units that all said that they would work with win7 64 bit i had to say enough. My 2 cents is these adaptors are a POS.

Since then I have put a serial card in my del xp pc and everything works fine. I am using 9 pin and 25 pin serial to rj45 adaptors that you wire yourself. Cost a couple bucks a piece. Also using a cat 5 cable to join the two. Works great.

I really appreciate all the help on this issue! Your input was a big help.

Thanks,

Kim
