Re: Looking USB to RS-232 + RS-422/485 Module ?

Hi Anton,

I have units which feature an isolated RS-232, RS-422, or RS-485 port. The interfaces are wired in parallel so there is no need to select the mode, just use the DB-9 or the screw terminals.

The units have unique serial numbers which means that windows will allow more than one or two (I have stacked 5 or more) without getting confused or losing track of which serial port number it was assigned to it. Since these are single port units you would need two. Let me know if you are interested and I can email you the data short.

Hi,

I need 2 simple Asyncronous serial ports on a laptop without any
serial ports. I have found many USB to RS-232 and a few USB to
RS-422/485 modules, but have not able to find a reasonably priced unit
that has one RS-232 port and one RS-422/485 port. We are currently
using a separate USB to RS-232 and USB to RS422/485, but the "COM"
port changes depending on the sequence in which they are plugged in.
This is for a test system where the people are fairly clueless, and I
want something that stays consistant.
