SV-EMS-220/221 Installation and ConfigurationThis section explains how to use Table 14–Sensor and Transducer Compatibility Level Key.There are three compatibility designations: A, B, and C. These designations are explained in thefollowing paragraphs.Sensor and transducer compatibility level A denotes that an SV-EMS-220/221 D37 pin labeledas “A” in Table 15 can be configured to support the vast majority of sensors and transducersused in aircraft installations, which are primarily resistive in nature. Sensors and transducersinclude contacts, fuel level, fluid pressure, fluid temperature, temperature, and positionpotentiometers. For example, SV-EMS-220/221 D37 pin 4 can be configured to read a resistiveoil temperature sensor.Sensor and transducer compatibility level B denotes that an SV-EMS-220/221 D37 pin labeled as“B” in Table 15 can be configured to support every sensor and transducer listed for “A” whilealso being compatible with 4 to 20 mA constant current source output sensors that aresupported (currently only the Rotax P/N 956413 Honeywell and Rotax P/N 456180 oil pressuresensors).Sensor and transducer compatibility level C denotes that an SV-EMS-220/221 D37 pin labeled as“C” in Table 15 can be configured to support every transducer and sensor listed for “A” whilealso being compatible with senders that employ active voltage output hardware includingDynon’s Capacitance-to-Voltage Converter.If an SV-EMS-220/221 pin’s sensor config space is blank in Table 15, that means that pin hasfixed functionality. This functionality is described under the Function column in the table.Sensor and TransducerCompatibility LevelABCExample sensors and transducersContactsFuel Level (resistive)0-150 PSI Fluid Pressure (100411-002)1/8”-27 NPT Fluid Temperature (100409-001)5/8”-18 NPT Fluid Temp (100409-000)0-30 PSI Fluid Pressure (100411-000)0-80 PSI Fluid Pressure (100411-001)Jabiru Oil TemperatureJabiru Oil PressureDynon 2-Wire OAT Probe (100433-003)Dynon 2-wire Carburetor Temperature (100468-000)Rotax CHT or Oil Temperature (801-10-1)Flap/Trim PositionEverything in A, plus can be connected to a 4 to 20 mA current sourcesender (e.g., Rotax P/N 956413 Honeywell and Rotax P/N 456180 oilpressure sensors)Everything in A, plus Dynon’s Capacitance-to-Voltage Converter andother senders with active voltage output hardware. Type C inputs canmeasure 0-5V DC, but can accept up to 15V DC without damaging theinput (any voltage above 5V is seen as 5V, however).SkyView System Installation Guide - Revision O 7-5
