one more thing to check I wonder if someone changed the pinout on the inside of your PT plus so they could use a printer cable? you might try a printer cable I'm pretty sure the only differance is 2 and 3 go strait thru on it.
when sending files from the your pc, you have to press the (tape rs232) key then the #(2) key then the #(1) key then the (+-) key on the PT plus then you hit send on the pc. also do you have your baud rate and every thing set right?
and make sure that you have a null modem cable if not it won't work trust me
I had to learn the hard way.

in hyperterminal and other software for connecting a computer to a CNC by serial cable when you send text
.
look for send
NOT send file
.
it is different, usually send is just for text (in the Hyperterminal window)
.
send file is for sending other than text like a jpg or zip file and other computer would need to be programmed to deal with the file type.
......you usually copy and paste text to Hyperterminal and what shows in Hyperterminal window you send to CNC. i admit copy and paste seems to be a extra step. there are other programs besides Hyperterminal. Mastercam comes with excellent text editors for sending and receiving text by serial cable. Even in Mastercam text editor I use Send and NOT "SEND FILE"
Red,thanks for all the tips,I would like to use the usb port also,similar to what you did.
Is your cable setup still working ok?
Do you think this cable would work with the null modem adapter you linked to?
Thanks for any more help,I'm kinda slow with computers.
DUH!I forgot to add the link to the cable I was reffering to!
Can I use this cable, http://www.cablestogo.com/product.as...=116&sku=22429 and the small null modem db25 adapter you linked to on e-bay?
I understand the null modem ,I have the PT manual.
Thanks again Red.
Thanks again Red.
I was getting ready to make a standard female to female null modem cable( like the proto book says) and realized my thinkpad doesnt have a male db25 serial port?I think?Its female and the book says dont confuse a serial port with a parrelel port.Well I have no idea how to tell the difference.I think I'll just wait and buy the usb cable and null modem adapter like you suggest.
WOW, this thread has been helpful. I am a teacher who has had the PT Plus and has just been using it as a stand alone unit for years. We had an Old Bridgeport with the PT Plus donated to our school in 2007 and I was told that it was only a stand alone unit. I have ordered the cables, downloaded a hyperterminal type program to run on my windows 7 laptop and gotten the communication to the mill. I can get it to the point where the machine lets me know it has received the file.... I can't get it to run. I made it as simple as I felt I wanted to test but still get no actual movement. Program Below. If anyone out there could help my kids would be psyched to start making robot parts using g&m code, not just standing in front of the machine punching in commands.

Hold down the start button for a few seconds then it will beep and ask what line you want to start at.
Thanks, bit of a brain fart there on my part. Seems so obvious once written. I now have the ability to send files to the PT plus but only files under 1kb. I tried sending a 1.4kb and it sat for over a half hour with receiving on the PT Plus but never got to receive OK. Will the speed of my laptop really have much to do with it or should I just have waited longer?
thanks again to all for your help. My kids are really happy to start building robot parts from files rather than typing in for every part.
Ok. Heres my experience.
I tried a 25 pin to usb adapter and got nothing.
I ended up using a printer cable that i rewired according to the attached diagram.
I used a 25 pin to 9 pin adapter at the pc end with a gender changer. It plugs into the PC's 9 pin COM1 not the 25 pin printer port.
Works perfect for about $20.
When sending files to the prototrak from hyperterminal, make sure that you disconnect after each file. I think this is what corrupted some of my files.
Hope that makes sense to someone.
We have a bridgeport series II with the prototrak plus system on it. So far this thread has been much help, thank you to those who have posted their findings. Have a laptop with win 8 on it and a 9 pin 232 port. So we purchased a 9pin to 25 pin serial cable and that is working fine.
Have tried both PUTTY and HyperTerminal for XP and like the HyperTerminal better. Also found out that our version of the plus likes .txt extensions on the files vs .cam. Our cad/cam program is enroute v5.1 and have been working with tech support there for a driver, but have ran into an issue.
I have tried the sample from the bobcad processor web site, and a sample from SWI themselves, they both upload and download fine, run fine with no issues. Our issue is I can run internal cuts and on center cuts for squares/rectangles, but if i try to do outside cuts on a square/rectangle, it loads in as a circle with a center point and gives an error 11 = not mathematically possible to do the cut. It does the same with circles.
Thanks for any help/suggestions may have.
Where is a good source of info for editing my programs in notepad.
I keep getting "RCV BAD DATA" when i try to send it back to the PT+.
Help me out with this and ill show you guys how easy a live 4th axis is for the PT. I just got mine 100% operational.
Here are a cpl programs that work on mine. This is output from my new eroute 5.1 processor. What post processor are you using? If the bobcad ones, there are quite a few and i did notice some differences with some with close to the same name. You may have to try a few to get the correct one.
Are you sure you have tool numbers? the ';' at the end of each line?
You also have to make sure you have HyperTerminal set up correctly at the correct settings.there are a cpl of links in the thread for the proto cad/cam book which gives you editing tips and rules that need to be followed. COM1, 4800 baud, 7 stop, 1 (forget the name), even parity. and none. I use strictly .txt files to upload with HyperTerminal.
You may need to work with your cad programs support for the post processor and possibly SWI to get any kinks worked out.

Hope some of this helps.
I dont use cam or anything to generate the code. I program the prototrak plus manually. I can send and recieve files fine. Some files i modify in notepad and the upload to the prototrak plus perfectly. But some will only upload some lines of the program and stop and say RCV BAD DATA. Its always the same programs on the same lines.
Do you have a PT +? Or another version of PT?
My codes for position drill are G100.
I was thinking it was maybe file size. But the biggest file I have uploaded just fine.
I would like to have a list of the protocol for the program text. Just what is allowed in what is not allowed.
Forgot to add that i do have to prototrak plus.
Not sure if read this post and downloaded the cad/cam manual, but this post has a lot of good info in it along with the link for the book. You might post the lines of code that are giving you fits to see if anyone can help as well.

On my XP computer in notepad there are 2 rectangle characters that appear in the line after the %. For some reason they didn't show up on this copy/paste.
I've tried ".;" at the end of lines, and tried it without the rectangles on my XP.
When sending this file to the PT from the XP it reads RCV BAD DATA, and it only uploads the first line. Some similar programs will upload 25 lines, read RCV BAD DATA, and leave off anything after the 25th line.
I'm sure its something simple that I'm doing wrong. Its just weird that some files transfer just fine, and these files will up load the first line only and error. It always uploads that bolt circle, and nothing else.
The 4th axis I built is very cool and super easy with the prototrak +.
The attached Ballpark file is what yours should look like. That is directly from SWI. Might want ot get rid of the excess 0's and is it the G104 and G105's that are giving problems, i dont see those an any other program or post have looked at for the Proto+
Only other thing i can think of is to contact SWI Tech/processors section and show them your posts to try and figure out what is wrong in your programs. Not that familiar with post processors, but thought some of the things had learned from earlier posts in here and in working with enroute and swi to get my enroute processor completed might help.
