HARD WARE AND SO FTWARE DATA Serial port EXP1 RS 485 Modbus RTU interface for PyroBus sensors Serial port COM2 RS 485 / RS 232 interface for second display (read only) The PM240 is a 320x240 pixel touchscreen terminal with a 3.5”colour TFT display. It allows the user to display data from up to eight PyroBus sensors and configure each sensor individually. The configuration parameters include emissivity setting, signal averaging, peak or valley hold processing and reflected energy compensation. There are two versions available. Each one provides all of the features above, however, the enhanced PM240E also provides analogue transmission for up to four sensors, plus two adjustable alarm outputs per sensor for all eight sensors.
