485 Wiring Connection Diagram. The RS232 of Pins de is MC power supply RSaSA Ground RJ4 plug pins are sorted by the sketch map is as shown above. Network wiring shall be executed with cable approved by DECK Monitoring.
First check the pinout connections and specifications of the devices you want to connect in order to determine whether you need a 2-wire RS-485 connection or a 4-wire RS-485 connection. 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. Connector types Controlsoft equipment uses two sizes of connectors.
When you use your finger or the actual circuit along with your eyes it may be easy to mistrace the circuit.
The RS232 of Pins de is MC power supply RSaSA Ground RJ4 plug pins are sorted by the sketch map is as shown above. The illustration on the right shows the connections. In order to avoid signal reflections a 120 Ohm termination resistance must be fitted on each end of the main cable. Please refer to the diagram below for correct Modbus network layout.
