Product Description
Adding an RS-422 interface to a PC
is now a snap. The Model 253 Interface Converter does this for full
duplex signals at data rates up to 19.2 KBPS, without requiring any AC
or DC power. With only TD, RD and ground, the Model 253 provides
operation over 8,000 feet of twisted pair into a load of 120 Ohms. The
Model 253 features a female DB9 connector, thus allowing it to be
plugged directly into any one of the PC's Com ports. When using the
Model 253 in this mode the DTE/DCE switch is positioned to the DCE
position.
