General Information 1.1 Function: This model of with RS485 provides communication facility on RS485 MODBUS. with RS485 works on a master slave configuration, where the is the slave and the master can be computer / PLC etc. The following are also supplied with this model: 2 numbers 120Ω End-Of-Line resistance. Guide to CRC 16 Calculation : n=0 1.2 General Points: For standard configuration, RS 485 serial link 2 wire is used to connect 255 with one RS232 port on the master (computer/plc etc.) over a distance of 1200 meters using MODBUS protocol. 1.3 Typical Network rchitecture: No MOVEMENT TO THE RIGHT CRC 16 CRRY OVER Yes RS 485 RS 232 n=n+1 emfis vifpe emfis vifpe emfis vifpe No n>1 Yes NEXT BYTE Cables and RS485/232 converter, computer are not supplied with this emfis vifpes meter. Recommendation: Please use a shielded twisted pair cable for connection repeater should be used if one intends to exceed the cable distance of over 1200 meters.
