Hi,
I already use the RS-232 to USB adapters with the product now. The
product I'm trying to create will talk to the legacy device serially
and store the data on the SD card for later retrieval.
I want to start with the USB serial client for a few reasons:
- a way to learn about the TS-7500, and prove that the TS-7500 talks
to the device. If the legacy software on the PC successfully talks
to the device through the TS-7500, then I get a warm and fuzzy that
the com port is set up right.
- a way to learn how to use the USB client port.
- Once I get this far, I'll have a starting point for the actual
production software that will run on the TS-7500. The USB client
port may or may not be part of the final product.
- I could use the USB serial port as a debugging aid, as previously
discussed in this thread.
Thanks for this link too: > http://www.linux-usb.org/gadget/
Thanks,
Erik
