PART 1: INTRODUCTION
Safety and EMC Considerations
ESD Warning:
Warning:
The following parts of the unit are ESD sensitive:
•
Antenna
•
LCD display
•
Metal connectors for signal and power
•
Metal body of sensor probes
EMC Considerations:
•
Whenever EMC is an issue, always use shielded cables.
•
Never run signal and power wires in the same conduit.
•
Use twisted-pair wires for differential signal connections.
•
Install Ferrite Bead(s) on signal wires close to the instrument if EMC problems
persist.
•
Failure to follow all instructions and warnings may result in injury!
Before You Begin
Inspecting Your Shipment:
Remove the packing slip and verify that you have received everything listed. Inspect
the container and equipment for signs of damage as soon as you receive the shipment.
Note any evidence of rough handling in transit. Immediately report any damage to the
shipping agent. The carrier will not honor damage claims unless all shipping material is
saved for inspection. After examining and removing the contents, save the packing
material and carton in the event reshipment is necessary.
If you need assistance, please contact the Customer Service Department nearest
you.
Manuals / Software:
The latest User Manual as well as free software including iConnect and Omega
Dashboard are available at the website listed on the cover page of this manual.

Description
The new, high-performance, long range, OMEGA
TM
ZW-ED wireless End Device
provides robust wireless environmental and process monitoring. The ZW-ED transmits
to a Wireless Receiver, such as the new ZW-REC. The ZW-REC provides web-based
monitoring of all of OMEGA’s IEEE 802.15.4 compatible Wireless End Devices.
The ZW-ED is IEEE 802.15.4 compliant and operates at 2.4 GHz. It communicates
over distances up to 1000m1 (3280'). The ZW-ED monitors and transmits Temperature,
Humidity, Light and Barometric Pressure. OMEGA offers a wide variety of compatible
sensors to suit every application.
The ZW-ED can run off of 2 Cell Batteries for up to 7 years. For applications that
require high update rates, or even longer up time, an optional AC adaptor is available.
The ZW-ED also offers strong data assurance. The receipt of each reading is confirmed
by the Receiver. If communication with the Receiver is lost the ZW-ED continues to
record readings and transmits them the next time you connect to the network. Even if
the ZW-ED loses power, the built in Real Time Clock (RTC) and RTC backup battery
keep a consistent time base.
The ZW-ED is designed to communicate with the all new ZW-REC. The ZW-REC
offers greatly expanded functionality over previous wireless receivers. The ZW-REC
can connect to up to 128 End Devices at once. The built-in web server supports
encryption to protect your sensitive data. The ZW-REC can also wirelessly update
firmware for the ZW-ED and Compatible Sensors.
The ZW-REC is designed to require no software to setup and run. A standard web
browser can be used to monitor and chart all sensor readings. The browser can also be
used for all configuration of the ZW-ED. Firmware updates for the ZW-ED and
compatible sensors can also all be loaded directly from the web browser.
Each ZW-REC receiver can support up to 128 ZW-ED End Devices and up to 8
receivers can be setup in one area allowing for networks of up to 1028 total End
Devices. For large networks the Omega Dashboard web server software can be used to
allow the monitoring of devices connected to different receivers from a single webpage.
