Figure 3 is an RS485 wiring diagram for RS485 pinout DB9 connectors. Figure 4 is a pin diagram for both 25 pin RS485 pinout half duplex and full duplex pinout connectors. The TxD and TxD lines carry transmit data while the RxD and RxD contain the receive data. The distances these signals are carried is greater due to differential signals.
EIA 485 (formerly RS 485 or RS485) is an OSI Model physical layer electrical specification of a two wire, half duplex, multipoint serial connection. The standard specifies a differential form of signalling. The difference between the wires? voltages is what conveys the data.
The corresponding pins will depend on your device’s user manual and the RS 485 cable connector type. For NI serial hardware connector pinout diagrams, refer to the Serial Quick Reference Guide. Half Duplex (2 Wire) For 2 wire transmission, you will need to short the transmit (TXD) and receive (RXD) signals together on the RS 485 port.
Variety of rs485 wiring diagram. A wiring diagram is a streamlined traditional pictorial representation of an electric circuit. It reveals the parts of the circuit as simplified shapes, and the power as well as signal links in between the gadgets.

Data Acquisition » Articles » RS485. Understanding RS485 and RS422. Those familiar with RS232 will know that the standard defines how RS232 lines should be driven electrically: what they are called, what information they carry and even the connectors and pin numbers to use. RS422 and RS485, by contrast, define only the electrical characteristics of the driver.
Proper Wiring for RS 485 . This application note is intended to provide basic guidelines for wiring an RS 485 network. The RS 485 specification (officially called TIA EIA 485 A) does not specifically spell out how an RS 485 network
Figure 4: Pinout diagram for DB 25 Connector. Most of the pins on DB 25 connectors are not connected since only nine pins are used for RS 232, RS 422, and RS 485 communication. To perform a loopback test with no hardware flow control with a DB 25 connector, connect pins 2 to 3 for RS 232. For RS 422 485 connect pins 5 to 20 and 7 to 22.
Note on RS 485 Pinout markings: Sometimes a device will be marked with the polarity reversed from normal RS 485 standards where the Data A or TD(A) RD(A) line is ( ) and the Data B line or TD(B) RD(B) is ( ). In a system with 2 wire connections, try reversing the lines to see if the device will respond.
