USB Driver Information
When the USB Tech Port is first connected to a PC, the PC will automatically try to
find a driver. It is unlikely to find a driver automatically, so the applicable USB driver
will need to be downloaded and installed.
The USB interface chip (FT245R USB FIFO) on the DMX-6PM controller board is
manufactured by FTDI (Future Technology Devices International) and requires an
FTDI driver loaded on the same PC as the PowerTerm® Lite software.
The driver type required is VCP (Virtual COM Port). The VCP driver makes the USB
device appear as though it is connected to a COM port.
1. Select the applicable driver to download from the following link:
The driver download is a ZIP archive folder named: CDM 2.08.28 WHQL
Certified. Save it in a convenient location.
2. Create a folder in a convenient location (recommend C:\FTDI Driver), and
extract the ZIP archive folder contents to the newly created folder.
3. Connect the USB Tech Port to the PC. The “Found New Hardware Wizard”
automatically pops up. Select the “Install from a list or specific location
(Advanced)” option and click “Next” to continue.
