3.4 Status LED 3.4.1 RS485-TX/RX: When the QIRF is connected to a Controller System through RS-485, the traffic of the communication can be monitored visually through the two RS-485 indicators. One is RX LED, which indicates the data stream received in the Controller. The other is TX LED, which indicates the data stream out of the QIRF. - Page 17 QIRF Operation And Maintenance Manual MENU MODE MENU MODE MENU MODE MENU MODE Down 1_ SYSTEM SYSTEM SETTING SETTING SUBDIVISION SEE SYSTEM SETTING Page Down 2_ ZERO ZEROING?

Address: Q4 Controller supports RS-485 addressing from 0 to 3 for digital sensor. The QIRF smart sensor RS-485 address can be defined from 0 to 255 to be used in RS-485 OptoMux or ModBus communication. Default address is Define Baud Rate for RS-485 OptoMux or ModBus Communication. - Page 20 Gas Type and Measurement Unit that are defined for the channel in M-Controller. AutoZero: QIRF is two channel detector, it’s designed to work in the situation where the Auto Zero function is not suitable. So QIRF discards AutoZero setting, QIRF will never do auto zero in background.
