QUESTION
I have no COM ports on my computer. How can I communicate with the instrument?
ANSWER
Use a USB-to-serial adapter or COM port PCMCIA card to add a serial COM port to your computer. The easiest (and cheapest) solution we found is to use a USB-to-serial adapter.
Commtest Instruments have tested and approved the BAFO Technologies BF-810 adapter with our software and instruments.
(Click the image below to visit the BAFO Technologies website.)
The BF-810 has a DB9 (9 pin) RS-232 serial interface that connects directly with the instrument's download cable (no other adapters required). The BF-810 can be obtained from www.pcwebshopper.com for around US $20.00.
The BF-810 is compatible with Windows 98/98SE, Windows ME, Windows 2000 and Windows XP.
Installation is straightforward as USB devices generally install themselves on any operating system that supports them. For full instructions, select your operating system from the list below.
MORE INFORMATION
There are many USB-serial adapters on the market, most of which have DB25 (25 pin) connectors which will require another adapter to the DB9 (9 pin) connector of the download cable. Feel free to use any adapter that you want to use; technically they all should work with our instruments but only the BF-810 has been tested and approved to work with our products.
