We are in need of a device that comes close to the specs below, if not
exact.  The only absolute requirments is: Sychronous and with a RS-422
connector.

A. Data Signals:             Send Data (SD), Receive Data (RD)
B. Data Rates:               122 bps to 5.1 Mbps
C. Format:                     Digital, Serial Binary, NRZ, 50%+/- 10% duty
cycle
D. Interface Spec:          TIA/EIA-422-B for 5.1 Mbps
E. Timing Signals:           Terminal Timing In (TT), Receive Timing Out
(RT)
F. Frequency:                122 Hz to 5.1 MHz

Thanks

I don't know too much about this except that RS485 is similar, but can use
higher voltage and go longer distances than RS422.

You might try http:/www.bb-elec.com/ which may be able to help or steer
you somewhere.  They have various serial equipment and adapters.  They
also donate webspace for our car club http://www.nsscc.com/ (one of our
members works there).
