The network devices may operate without the signal ground connection but may not be reliable Some RS485 applications require impedance termination because of fast data rates or long cables The most popular termination involves installing a V2 watt resistor across the receiver at each end of the network See the RS485 interface user manual for termination requirements on the PC being used Alternatively the preferred network may be AC terminated by placing a 0 01 uF capacitor in series with the terminating resistor The capacitor appears as a short circuit during signal transitions but appears as an open circuit to any DC loop current This will reduce the power supply current required to operate the network and still provide the proper terminating impedance Do not add a terminating resistor to every receiver in the network For networks with more than about four nodes the transmitters will be unable to drive the cable Only terminate both ends of the main cable B 4 Modbus Interface 60 The multiprobe is configured to respond to Modbus function 3 Read Holding Registers in RTU mode through the RS232 or RS485 communications port at 19200 baud 8 data bits Even Parity and 1 stop bit 19200 8 E 1 All data values are returned in IEEE Floating Point Format 4 bytes Each data value is returned in two 16 bit words with the low word being transmitted first Within each word the high byte is transmitted first Each byte is transmitted

72. se in Balanced Digital Multipoint Systems RS485 involves sending an inverted or out of phase copy of the signal simultaneously on a second wire This is called a balanced transmission Any outside electrical noise adds coherently to both signal copies The receiver electrically subtracts the two signals to reproduce the original signal The advantage in the subtraction is that only the intended signal gets reproduced since they are out of phase The in phase noise on the two wires are also subtracted from each other to produce a net zero noise component in the reproduced signal This noise immunity allows the RS485 interface to transmit digital signals at faster rates over longer distances than the RS232 SDI 12 interface The RS232 SDI 12 interface does not use balanced transmission and is therefore susceptible to noise interference which limits the transmission distance and speed Connections RS485 can use two wires to both transmit and receive data A common software protocol must be shared between devices to prevent data collisions on the wires RS485 also allows for multiple transmitters and receivers to be easily connected together Be sure to connect the signal grounds of all devices on the network together The connection can be made using a conductor in the transmission cable or each device can be connected to a good earth ground This connection keeps the common mode voltage the voltage which the signal must overcome to be reproduced low
