If you want, you can easily construct your own external RS422 to RS232 
Just use a Max 232 to convert the RS232 signals to TTL/CMOS and connect 
RS422 receiver and transmitter chips to that.
RS 485 transceivers chips can also be used instead of RS422 transmitters 
and receivers, just connect them as drivers or receivers as required.
If you need a circuit schematic I can send you one.

Novatel also use Deutsch connectors on some of their enclosures.
