Connectors and signals
 DB-9 female connector on the RS-232 side and DB-9 male connector on the line side.

RS-232 Side:

Connector: DB-9 Female.

Signals: Use Pins 3 (RD) and Pin 2(TD also called SD)   Pins 7 (RTS) and Pin 8 (CTS) are tied together Pins 4 (DTR), 6 (DSR), and 1 (CD) are tied together.

Line Side:Use Pin2(R+),Pin3(T+),Pin4(T-),Pin5(R-)

Application

AN-EXT-RS-232

RS-232 signal extender

Description

AN-EXT-RS-232 extends full-duplex transmission of asynchronous data over four wires (two twisted pairs). The data transmission between each line driver utilizes differential signaling that is immune to electrical interference and therefore makes it ideal for use in light manufacturing and industrial office areas. It can run up to speeds of 57.6 kbps
