The Lantronix UDS100 has a DCE connector.  The outputs are DCD, DSR and 
CTS.  Your other cable will not work.

Try putting a little gadget with LED indicators on the output of the 
UDS100.  Fiddle with the flow control until you get at least one of the 
output control lines always high and one always low when the port is 
open.  If that can't be done, try to find away to make the weather 
station work without it or get another device.  If you can get a high 
and a low control line, then wire that up so it works.

The Lantronix UDS100 can be powered either from the DCE connector on 
special lines or via a separate power connection.
