The other non-standard part of the Z3801A is that it comes setup for RS422 
rather than RS232.  So I'd check with a scope during power up before doing 
anything more complicated.

There are jumpers inside so it's easy to switch to RS-232.  But it might work 
most of the time without that if you get the wiring right and are lucky, and 
any particular USB gismo might not be lucky enough.

These are my opinions.  I hate spam.
