Overview |
|
|
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! |

|
DB-9 (EIA-574) Versions Also Available
If you need to convert a DB-9 Serial port to RS-422, you need the
Patton Model 222N9
Note: Model # 222N9FT (shown above) comes with thumbscrews.
Other 222N models come with slotted captive fasteners.
