The Patton Model 222N Series of converters now comes in two “flavors”: The
Model 222N allows an RS-232 device with DB-25 port to connect to an RS-422
device up to 4000 feet away over two twisted pair. The Model 222N9 does the
same thing for an RS-232 device with a DB-9 port (now called EIA-574). Both
converters support data rates up to 19.2 kbps, and require no AC power or
batteries for operation. All handshaking lines are looped back. The Model
222NRC is a dual rack card version of the Model 222N, with two converters in
one card!
