Hmmm...only 3 wires would indicate it's only using RX/TX and GND.
What USB adapter are you using?
When I had a quick scan of the AM882 manual earlier, it said use a baudrate of 38400.
However whatever software is using the COM port should configure the port itself, ignoring any windows settings.

This is my cable, it's a USB to serial converter then a short length of cable cut from an old phone with the correct plug already fitted.
I used default settings for everything else.

If you plug it all in then on your PC go to, Settings - System - Device Manager, you will see if it's connected and which COM port number it has. In my case it's showing the USB to serial converter on COM10

As you can see I get an error when trying to read from the drive, this has always been the case with my system ( Windows XP ) and I've never followed it up, but I might now.

To be honest I would just as soon use the DIP switch 4 method as described in the manual , where you quickly switch it twice and the drive will set itself up.
Nah it's too hit n miss and you never know if you've done it fast enough, software is 100%. Also you can set the amp's for the motors exactly.Quote:

Every time I use the 'switch 4 method' I can hear the stepper motor 'singing' while it goes through the routine.Quote:

Well yes suppose that makes sense really because you would want to read the drive for it's current settings before changing them.Quote:

Eddy, I've been playing with Protune on my XP machine today. I kept getting the error that you show. After a bit of research it turns out that it is due to the file stored in RAM on the drive being generated in a different language (probably from a Chinese machine).
If you go to Control Panel - Regional and Language Options then click the Languages tab and tick 'Install files for East Asian Languages', once it is applied you won't get the error message anymore.
Si.
Here is an example of what I am seeing. The four error screens should be read right to left.
1.Start ProTune, Select Com1 all ok so far.
2.Select 2nd icon from left, Read/Write drive parameter. OK So far.
3.Immediately I get error message 1, please check if the communication cable or drive is OK.
4.I click OK and I get the message Read finish successfully.
5.I see Screen 2. The parameters Configuration screen.
6.I leave this open or closed, dosent matter, I want to do something interesting and Select 4th icon from left, System Config.
7.Immediately I see Com Error! message, Please check connection and restart!
8.I click OK and immediately I see screen 3, the SystemConfig screen, clicking Start does nothing.I cant close this screen top right.
9.So I decide to close the whole application, restart and go straight to System Config, I see error message 4, Com Error, Fail in reveiving monitor data.
Thats about it, I have to click OK 4-5 times to close the dialogue and the protune app essentially does nothing for me.
I'm still not convinved I have the cable wired correctly, can anyone confirm the pinouts above please? They are as per the leashine data sheet but I just want to be sure.
Tony, it looks like a problem with the cable to me. I bought mine from Gary @ Zapp so i'm not sure of the wiring. There is a little thread on Zapp's forum which talks about the cables : Zapp Automation Ltd
Not sure it it'll help, but maybe worth a quick read.
Si.
I'm almost certain it's not going to be COM1, did you look at the ports in device manager ? while you are on that page, keep plugging/unplugging your interface cable a few times so you can identify which component is changing then you can see which COM port it's using.
