SV-EMS-220 Installation and Configuration
SkyView System Installation Guide - Revision K 7-5
Sensor and transducer compatibility level A denotes that an SV-EMS-220 D37 pin labeled as “A”
in Table 15 can be configured to support the vast majority of sensors and transducers used in
aircraft installations, which are primarily resistive in nature. Sensors and transducers include
contacts, fuel level, fluid pressure, fluid temperature, temperature, and position
potentiometers. For example, SV-EMS-220 D37 pin 4 can be configured to read a resistive oil
temperature sensor.
Sensor and transducer compatibility level B denotes that an SV-EMS-220 D37 pin labeled as “B”
in Table 15 can be configured to support every sensor and transducer listed for “A” while also
being compatible with a 4 to 20 mA constant current source output sensor.
Sensor and transducer compatibility level C denotes that an SV-EMS-220 D37 pin labeled as “C”
in Table 15 can be configured to support every transducer and sensor listed for “A” while also
being compatible with senders that employ active voltage output hardware including Dynon’s
Capacitance-to-Voltage Converter.
If an SV-EMS-220 pin’s sensor config space is blank in Table 15, that means that pin has fixed
functionality. This functionality is described under the Function column in the table.

Table 14–Sensor and Transducer Compatibility Level Key
Future firmware updates may expand the scope of the compatibility levels listed in Table 14.
The tables on the following pages specify the sensor and transducer types that are supported
by each pin on the male D37 and female D25 SV-EMS-220 connectors and the wire harness wire
