Patton Electronics’ 222N line of serial converters connects computers, terminals, and modems employing an RS-232 interface with a DB-25 port to RS-422 devices. It supports data rates to 19.2 kbps over two twisted-pair lines. The unit derives power for operation from the data and control voltages on the RS-232 interface - it does not require AC power or batteries. All handshaking lines are looped back over RS-232.
The 222N features bi-directional data conversion at full or half-duplex at distances up to 3.5 miles. An external DCE/DTE switch selects the serial port of either a computer/terminal (DTE) or a modem (DCE) without a crossover cable. The 222N is available with several RS-422 connectors options: DB-25 male or female (following the RS-530 standard), RJ11, RJ45, or terminal blocks with strain relief.
The surge-protected models, 222NS, suppress transient surges and directs them safely to chassis ground. Compliant with IEC 801.5 level 2, 1kV, the 222NS protects itself and connected equipment from nearby lightning strikes and electromagnetic radiation.
