[comp.protocols.ibm] NRZI conversion

I wrote an SDLC control unit emulator for a board I inherited.
Not hard to do considering I work for the company that brought
you IRMA.

But the serializer on the board only handles NRZ data.  No NRZI.

We can't change the board.  Is there anything on the market
that I can attach to the line which will use the clock to convert
the data signal from NRZI to NRZ so my board can read it?
Seems like there ought to be, but I can't find it...

I wrote an SDLC emulator for a multiplexor board I inherited.
Not a tough job considering I work for the company
that brought you IRMA!

The problem is the serializer on the board only handles NRZ.
It can't hear NRZI.

Seems like there ought to be an attachment for a line that
will sync off the clock and convert the data signal from 
NRZ to NRZI and vice-versa, but I can't find it.  Any help?

Thanks.--
