Depending on the terminals added to the configuration server, the minimum accessible parameter values are displayed. “Signal type” — select signal type (Figure 14). Possible values: “Off” , “Ignition key”, “CAN-bus”, “RPM input” (find more details in Omnicomm Configurator User Manual or Omnicomm Terminals Operating Manual). To check the presence of a signal, the field “Current RPM value” must display a value other than zero. In the ab- sence of a signal, switch on the pull-up resistor by selecting “On” in the respective field. “RPM calibration factor” — enter the calibration factor value. Possible values: from 0.00001 to 10000.00000 within the accuracy of 0.00001.
