greater than, 10Mbps. RS-485 is designed to transmit this information over significant lengths, and 1000 meters are well within its capability. The distance and the data rate with which RS-485 can be successfully used depend a great deal on the wiring of the system. Wire. RS-485 is designed to be a balanced system.

Wiring RS-485 Networks To wire the connections, carefully strip about 1/4” of the conductor insulation, insert the bare conductor into the correct terminal orifice and then fasten the screw. Controlsoft recommends using a slot-head screwdriver with a blade 3/32” wide (suitable for size 0 or 1 screw). The

earthed. Poor shielding or earthing is a very common wiring error! Fig. 1 RS485 Wiring Diagram i The 2 cores in the twisted pair cable carry the Data Line plus (normally red) and minus (normally green), or B-Line and A-line and are surrounded by the shield as shown. It is essential that the core colours are used consistently

RS-422/485 Wiring Diagram (2 Wire) Intellicon Adapter RS-485 Peripheral. Note 1: The RTS and CTS connections are not necessary if you jumper the CTS selection ( J9 and J10 ) appropriately on the Intellicon-6+2. Note 2: These pinouts only apply to the Intellicon-(Flex8, 6+2) and Dflex adapters with the RS-422/485 options. This Intellicon 2 and 4 have a different RS-422/485 Pinout.

2.4 Unit Load (U.L.) A one RS485 transceiver represent a load of 1U.L. The RS485 standard specifies the bus loading as 32 U.L. 2.5 Shielding and Grounding The RS485 interface standard does not specify a ground wire, but such wire is needed to provide a return path for common mode currents and consequently reduce emissions.

The diagram below indicates how you would go about connecting two PC's together, without handshaking. Connecting two PCs together using RS232, without handshaking When Handshaking is required, generally RTS of one device connects to CTS of the other, and vice versa, and also DSR of one device connects to DTR of the other device, and vice versa.

2 Wire For Modbus Rs485 Wiring Diagram.pdf rs485 - rs485 cables – why you need 3 wires for 2 (two rs485 - rs485 cables – why you need 3 wires for 2 (two) wire rs485. rs485 needs 3 conductors and a shield. many people say its a two wire network but it is not. two conductors are used to carry the rs485 differential voltage signal. the shield is connected to earth/ground at one end ...

Many of the more common problems associated with RS485 network stability can be mitigated by following these recommendations for wiring, termination and line bias. The items in this document are presented as points of interest to designers and installers of Modbus networks.
