I haven't used this particular model.  I have used similar units from 
Systech, purchased on eBay for less than $30 US.  They work quite well. 
  Some of them have selectable RS-232/RS-485 outputs.  I've successfully 
used both types of outputs.

The only problem I've had was the initial configuration.  The trick is 
to configure the serial ports as a "Reverse Telnet" server.

Search eBay for "terminal server".  You can also search the Time Nuts 
list, they were discussed a few years ago.
