Q. Why isn't my USB to Serial adapter working?

A. Since the release of Windows XP many laptop manufacturers no longer have a "proper" serial port at the back. Notable exceptions are quite recent IBM Thinkpads and some Dells with the docking station. Instead there are only USB ports. As a result users are finding that a USB to serial adapter is the only way they have to communicate with their CNC machines.

Unfortunately all USB convertors are not created equal, especially if they contain the "prolific" chipset. Devices intended for use at home are now expected to work in the harsh industrial environment, and unfortunately many are not up to the job. Many manufacturers of USB to serial adapters are not 100% compatible and communication to with CNC machines is either unreliable, very slow, or limited to one way transfer.

For laptops you could use a PCMCIA/Express to serial card, they are far superior and often not much more expensive, preferably with some form of isolation.

If you must use a USB device, then we have used Keyspan USB to RS232 adaptor cables - they work great when others just don't >> Click Here or Here and are reasonably priced. We have reports from several users that MOXA are also reliable.

Please take time to watch this video for additional information and resources about USB devices from BB-Electronics. This company sells more robust rugged USB devices (albeit more expensive) much more suited to industrial applications Often it is worth spending more money initially, than wasting time when you cannot get the USB to work.

Unfortunately it's not as simple as listing USB to RS232 devices that work for one user, because sometimes the same one will not work for another. So whilst we list several options above, there is just no 100% guarantee that any will work with your computer.

Quite often we think that it is well worth the while to buy a secondhand laptop off ebay with a proper serial port. In many cases this would work out cheaper and far more reliable than having to buy things such as USBs or Express cards.

Q. When I try to change the CNC settings, it says I have insufficient access to save the changes away.

A. This is because you do not have rights to edit the settings file. This file is called "pronc-settings.ini" or "proeznc-settings.ini" or "proezdnc-settings.ini" depending on your dnc software package title, and is located in the program's home default folder.

Right click the appropriately named "pro****-settings.ini" file, and then click properties
Click the security tab
Under group or user names, click your name and see the permissions you have. You need full control

Q. Will your dnc software work with my CNC?

A. This is one of the most commonly asked questions. All we can say is that if your CNC supports the RS232 protocol, then yes it will. We even supply a list of predefined CNC templates to get you started for many popular machines. We do not support exotic proprietory protocols that are outside the scope of RS232, such as LSV2, Fidia etc.

Q. What computer access rights should I give?

A. Our dnc software needs to be able to create temporary files and be able to write to your system registry. If it can't it may lock you out saying its expired. If you get this, then you should do the standard thing of giving users full access and then gradually tighten things up. For typical use, a standard "power user" would be just perfect, they have Modify, Read/Execute, Read and Write properties.

You should install our dnc software using Admin rights and run the software at least once with admin rights to ensure correct operation and installation of the software.

Q. Do I need any specific hardware to use your software?

A. Depends. If you are using a PC computer or a laptop that has a free com-port in the back then no you dont need anything extra. If you are using a newer laptop, then the odds are that you may have a USB port only, in which case the cheapest a USB to Serial cable convertor, they are cheap only about $30 However, we always recommend either PCMCIA or EXpress cards as they are usually far more reliable than USB

Q. How much is all this going to cost me ?

A. You can see our latest price list click here.. We give great discounts for multiple purchases, and once you have bought there are no upgrade costs, ever.

Q. Does your dnc software support Heidenhain Blockwise for drip feeding large files?

A. ProEZNC and ProNC do, but not in remote dnc operation.

Q. Does your dnc software support Haas Xmodem for drip-feeding large files?

A. ProEZNC and ProNC do, but not in remote dnc operation.

Q. Does your dnc software support Mazatrol?

A. No.

Q. Does your dnc software direct TCP/IP transfers to Wireless devices?

A. Yes by using virtual com ports that will be configurable using the software that is supplied by your hardware vendor.

Q. After I receive the unlock file it does not register.

A. Please follow the instructions in our e-mail that we send you after purchase. You have to do it in a specific sequence. We have never had a code fail, we are afraid it is always down to incorrect input or failure to follow our instructions.

Q. Do you charge an annual maintenance fee?

A. No. Unlike other DNC software vendors we don't do it, once you have paid for our software that's it. You can download the latest version at all times free of charge. After 5 years from your last full license purchase we charge a small admin fee for replacement keys. This means that if you don't need a new key there is no charge, much better than an annual charge, you only pay for what you need.

Q. I want to run your dnc software on more than one computer, can I copy it onto more than one computer with a single license?

A. You need a license for every computer you run our software on. We look at it this way. If you made 100 parts for one of your customers, would you charge him for 1 part or for 100 parts ? However, we have price breaks and we offer very good discounts for multiple licenses.

Q. Which languages does your software support?

A. It is only available in English.

Q. What is your software export information?

A. ECCN=5D992
