2 EN7016SK Overview
The EchoStream survey kit is a portable, easy-to-use system for
conducting EchoStream site surveys to determine optimal location
of Inovonics wireless receivers, high-power repeaters and end-
devices.
2.1 Measuring Signal Strength
The EchoStream survey kit measures the signal strength of high-
power repeater and end-device messages to help optimize your
EchoStream system. The EchoStream survey kit provides you with
two signal strength measurements: signal level and signal margin.
Signal level The signal level is the measurement of the overall
decibel level of the message.
Signal margin The signal margin is the measurement of the
decibel level of the message, minus the decibel level of any
interfering signals. Inovonics Wireless equipment should be placed
within a facility such that all end-devices produce signal margin
readings of at least 4 decibels.
Both the signal level and signal margin are measured in decibels.
Because signal strength and signal margin are measured on a
logarithmic scale, the difference between a decibel level of 3
(Weak) and a decibel level of 4 (Good) is a much larger difference
than it would be on a linear scale.

2.3 EchoStream Survey Kit Components
Figure 5 EchoStream Survey Kit Components
The EchoStream survey kit is battery-powered for portability. The
following components are included in the survey kit:
• An EN4016SK EchoStream survey receiver
• An EN1223SK survey transmitter for testing the location of
pendant transmitters or two-way end devices
• An ES1210SK survey transmitter for testing the location of all
other end devices
• A flat-blade screwdriver
• A Phillips screwdriver
• The EN7016SK EchoStream Survey Kit Installation and
Operation Manual
You will also need:
• A set of four fresh AA alkaline batteries, or four fully-charged
AA NiMH rechargeable batteries, for the receiver
You may also want:
• Headphones with a 3.5 mm plug
• A battery charger, if using rechargeable batteries
- Inovonics Wireless recommends either Rayovac PS5/PS6 or
Energizer CH30MNCP-4 batteries
3 Configure Survey Transmitters
Note: The survey transmitters are designed for use with the survey
kit only. Survey transmitters should not be used to perform range
tests with any EchoStream receivers other than the EN4016SK
survey receiver.
EchoStream products are adaptable to various radio frequency
bands. If you are using the EN7016 survey kit anywhere except
North America, you will need to configure the survey transmitters
for the frequency band appropriate to your geographic area. All
EN7016 survey transmitters are set for North America by default. If
you are performing a site survey in North America using the
EN7016 survey kit, there is no need to configure the survey
transmitters.
3.1 Select EN1223SK Survey Transmitter
Frequency Band
The EN1223SK survey transmitter is shipped with the frequency
band set for North America. If you are using the EN1223SK in
Australia or New Zealand, you will need to set the frequency band
for your geographic area.
1. Use the small Phillips head screwdriver to remove the three
housing screws on the back of the unit.
2. Remove the front of the housing.
3. Place a selection jumper on the appropriate frequency band
selection pins (6).
• Place the jumper on the left two pins, marked AU, to set the
frequency range to 915-928 MHz for Australia.
• Place the jumper on the right two pins, marked NZ, to set the
frequency range to 921-928 MHz for New Zealand.
• Leave the jumper off the pins to set the frequency range to
902-928 MHz for North America.
Note: North America is also selected when the jumper is either
attached to one pin or no pins. Attaching the jumper to one pin can
prevent the jumper from being lost when selecting the North
America.
