MPM4783 Intelligent Digital Pressure Transmitter(vl.l) Electric connection Terminal Electric connection for transmitter with RS485 interface(MODBUS Protocol): Assistant Software RS232/485 Conversion module is used to communicate with RS485 interface transmitter, available for real time pressure/temperature display and calibration on site. Some parameters calibration was done before being transported at factory, so users do not have to modify them. When mistaken operations happen, users can press “Back to Factory Setting” to turn it to factory setting. Besides, the software keeps Data Record section,...
