1.5 Description
The new, high-performance, long range, OMEGATM ZW-REC wireless receiver provides
Web-based monitoring of OMEGA’s IEEE 802.15.4 compliant wireless End Devices including
the zSeries, UW Series
1
and zwSeries.
The ZW-REC is IEEE 802.15.4 compliant and operates at 2.4 GHz. It is designed to
communicate up to 1000m
2
(3280') to various wireless sensors including the all new ZW-ED.
The ZW-REC connects directly to an Ethernet network to serve active web pages and display
the data. It enables monitoring and recording of Temperature, Humidity, and Barometric
Pressure over an Ethernet network or the Internet without any special software—just a Web
Browser. OMEGA offers a wide variety of different wireless sensors and transmitters to suit
every application.
The ZW-REC offers expanded functionality over previous wireless receivers. The ZW-REC can
connect to up to 128
3
wireless End Devices at once. The built in web server supports
encryption to protect your sensitive data. The all new web pages run HTML5 and are ready to
use on mobile devices. The ZW-REC can also wirelessly update firmware for compatible End
Devices and 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 to configure
the device’s IP address, passwords for access and overall configuration parameters. Firmware
updates for the ZW-REC itself, compatible End Devices and sensors are loaded directly from
the web browser. The web server supports HTTP over TLS (HTTPS) which provides a secure,
encrypted, connection between web browser and ZW-REC receiver.
Each ZW-REC receiver can support up to 128 End Devices and up to 8 receivers can be setup in
one area allowing for networks of up to 1024 total End Devices. The Omega Dashboard web
server software can monitor and log data from one or more receivers from a single webpage.
The Omega OPC Server is available for customers with existing SCADA systems, to connect the
ZW-REC directly to their PLC or Historian. A free trial of the OPC Server is available for
evaluation purposes. Please contact Customer Service for more information.
1Refer to the Omega Website for a list of compatible UW Series devices.

2.2 DIP Switches
The ZW-REC has two banks of DIP switched located on the back of the unit for easy
configuration. Figure 3 shows a close up view of the switches. To change the DIP switches, use
a tweezer or small screwdriver to gently push the switch. Do not apply excessive force.
Setting the Network ID
The set of 8 switches on the left selects the Network ID. The Network ID (NID) identifies which
End Devices the ZW-REC communicates with. If there are multiple Receivers deployed in the
same area each one must be assigned a unique NID. Make sure the same NID is selected on
the ZW-REC and the End Devices. Only switches 5 to 8 are used. Do not use switches 1 to 4.
zSeries End devices only support NIDs 0 to 7. UW Series End Devices require a 5 digit NID
referred to as a PAN ID for configuration. The PAN ID corresponding to each NID is listed in
Table 1 . Consult the user manual of each specific End Device for more information.
Table 1. Network ID DIP Switches
Warning: The NID may be set with a different set of switches depending on the
type of End Device. Please refer to the user manual for the End Device to
determine which switches correspond to the NID.

DHCP and Defaults
The set of 4 switches near the Ethernet port are for basic configuration. Switches 1 and 4 are
reserved and should not be used.
Switch 2 is used to reset the ZW-REC to factory defaults. This is useful if the IP address or
password to the ZW-REC is lost. To set the Receiver to factory default settings perform the
following steps:
• Remove power from the ZW-REC.
• Slide DIP switch #2 to ON position.
• Power the ZW-REC on and wait about 10 seconds until the Receiver fully boots up.
• Set the DIP switch #2 back to OFF position
Note: Make sure that the DIP switch is set to OFF before resuming normal
operation. When the switch is on, every time the unit is power-cycled the factory
settings are loaded. The switch may be changed while the unit is running but this
has no effect until the ZW-REC is reset or power cycled.
Switch 3 is used to force DHCP on. Changing Switch 3 to ON enables DHCP the next time the
ZW-REC is powered or reset. Turning on DHCP in the manner overwrites the webpage setting.
This is useful for situations where it is not possible to connect to the default IP address. Please
see Section 3.3 for more information on requirement to use DHCP.
To disable forced DHCP change Switch 3 to OFF and reset the device. DHCP remains on until it
is changed from the webpage or the device is reset to defaults.
2.3 Reset Button
Pushing the Reset Button while the ZW-REC is powered reboots the device. Holding the Reset
Button for 9 seconds resets the ZW-REC to its factory default settings. To access the Reset
Button carefully use a small screw driver or paperclip to depress the switch through the
pinhole shown in Figure 4 . Do not apply excessive force as this may damage the device.
