Usb Serial Adapter Driver Windows 7 Gmus-03: Best Practices and Recommendations

DB9 'straight-thru' male-female serial cable (if your physical workspace is close to your USB port you may be able to do without it and connect your USB-serial adapter straight to the XWisp 628 programmer board)

The total costs add up to around 77-105 USD excluding shipping and handling, depending on your choices. As you may have noted, the GMUS-03 USB-serial adapter is considerably cheaper than the Keyspan. GMUS-03 Drivers for every flavour of OSX are available and the thing works admirably for what we are doing in this article. However, whilst Keyspan have certified their adapter with a great many serial devices, with the GMUS-03 your mileage may vary.

Depending on the cable length you need between your USB port and your physical workspace, you can connect the Wisp628 board directly to the USB adapter or connect it using a 'straight-thru' DB9 serial cable,

Now we can work on the software side of uploading the ledflash.hex file to the target circuit. For this we use the Python-based XWisp. Before we can issue the upload command we need to do three things. Firstly, we make a small modification to one XWisp source file to enable XWisp to run on OSX (Just as with the Jal source, you may find that in the latest release of XWisp, this modification may not be necessary anymore). Secondly, we copy the XWisp folder to /usr/bin. And, finally, we find the name of the serial port provided by the USB-serial adapter and its driver software.

If you have the Keyspan adapter, look for a serial port named something like tty.USA19QW181P1.1. The name may differ with the exact type of Keyspan adapter you have got. If you use a GMUS-03, look for a port named something like tty.usbserial0. Note down the name somewhere as we will need it in a moment.

OK, ready? We have xwisp.py living in /usr/local/xwisp, ledflash.hex living in our working directory and a serial port living in /dev. Now, on a single line, type this if you have the Keyspan adapter:

Usually, you can figure out from the error message in Terminal if you do not address the serial port correctly (If you use the Keyspan adapter you can look at its LED: it should start flickering during uploading of the hex file). If not, check the physical connection between Mac and USB-serial adapter, check the name of the serial port, and make sure that you have specified the complete path: you really need that /dev/ in front of the port name.

Sorry about wrong information. I checked converter it is profilic GMUS-03 USB-Serial adapter.And still other test with other PC (DELL laptop with build in serial port) gives same result.usb-serial.png816612 32.5 KB 2ff7e9595c
