SV-EMS-220/221 Installation and Configuration
7-6 SkyView System Installation Guide - Revision R
This section explains how to use Table 13–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 14 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 14 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 14 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 14, that means that pin has
fixed functionality. This functionality is described under the Function column in the table.

Everything in A, plus can be connected to a 4 to 20 mA current source
sender (e.g., Rotax P/N 956413 Honeywell and Rotax P/N 456180 oil
pressure sensors)
C
Everything in A, plus Dynon’s Capacitance-to-Voltage Converter and
other senders with active voltage output hardware. Type C inputs can
measure 0-5V DC, but can accept up to 15V DC without damaging the
input (any voltage above 5V is seen as 5V, however).
