laptop to BX24 USB

Started by David Manley March 31, 2003
Most modern computers are all coming out with USB ports
only. They have no Com (DB9 Type) , I know that there
cables with converters readily available, but I have been told
they are not able to deal with two way communication required
during programming and monitoring the BX24 port.



you can get pcmcia serial ports they are about 130.00 there are several types.

I have been successful with using a USB-2-Serial adaptor with the Basic
Stamp 2, but I have not had a chance to try it with the BX24 yet. I also,
have heard the same rumors that you can't use them with the BX24. I'll let
you know if I get mine working.

I have successfully used Rev 1 of the FTDI evaluation cable...

I'm confident that Rev 2 will also work.

If you need multiple USB-serial ports, ByteRunner has up to 8. Some
models are also FTDI based.

I had difficulties with several USB-serial adapters, but the one I use now works
perfectly! It's a Keyspan "High Speed USB Serial Adapter" model USA-19W. Note:
the older "USB PDA Adapter" I had (USA-19X) did NOT work.

In a separate, but related note I am succesfully using the FTDI FT232BM USB
interface chip with a BX24 project. I do not use it for programming the BX24, but
for BX24-to-Host communications. They work great. I bought the plug-in modules
made by GigaSystems (#USBMOD1). Check out:

http://www.saelig.com/giga.htm

Note that the FTDI chips & giga modules use TTL level signals so you can connect
them directly to the BX chip pins. Be sure to configure the BX for "non-inverted"
serial.

For what it's worth, I just picked up one of these, and finally was able to get my Apple
PowerBook (15" Ti, 667 MHz) to talk to a BX-24. Development system works just fine
on VPC 5 using either Win95 or WinMe.
