Why was there a need for this conversion in the first place?
Why did the RS232 port constraint arise in the first place?
Was it because somebody is trying to get by on the CHEAP with junk?
That would certainly limit the options.
Buying a USB card to stick in the junker computer would probably be the cheapest route, and would open up other fast USB options like flash drives, USB printers, etc.
If there's a decent reason for the RS232 constraint at the outset, please state the reason.
Otherwise it just seems like the result of somebody being too much of a cheap ass to buy a USB card to stick in a junker.
That USBwiz is NOT for that situation!
At 29.95-59.95 that USBwiz is basically intended to build into some type of embedded system right? Or some type of new consumer Personal Computer main board using lots of FPGA and a ""mezzanine"" right?
PCI USB card or 5-PORT USB 2.0 PCI HUB CARD $2.19 to $3.67 SHIPPED to the USA
I found a serial port mouse New in Box $4 shipped to USA.
Lots of mice are designed for the DIN(PS2) port and have an adapter for legacy support through a DB9 RS232 port.
There are RS232 to USB converters which use a "Built-in TTL PC-PL2303 Chip" but the ones I see are for providing a RS232 port on a USB computer, not the other way around. $7 price range as well.
One outfit has a bridge module for this that has both genders of DB9, a USB A port and two little circuit boards sandwiched with a Silicon Laboratories 2102 chip for $15 Still, not quite what you'd want for putting a USB mouse on a DB9 RS232 port.
I'm still betting that adding the $4 USB card to the computer makes more sense.
What do you think, Paul Ingram (OP) ?
