SV-EMS-220/221 Installation and Configuration
7-6 SkyView System Installation Guide - Revision S
This 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 the
following paragraphs.
Sensor and transducer compatibility level A denotes that an SV-EMS-220/221 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-220/221 D37 pin 4 can be configured to read a resistive
oil temperature sensor.
Sensor and transducer compatibility level B denotes that an SV-EMS-220/221 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 4 to 20 mA constant current source output sensors that are
supported (currently only the Rotax P/N 956413 Honeywell and Rotax P/N 456180 oil pressure
sensors).
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” while
also being compatible with senders that employ active voltage output hardware including
Dynon’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 has
fixed functionality. This functionality is described under the Function column in the table.
