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 Series1 and zwSeries.

The ZW-REC is IEEE 802.15.4 compliant and operates at 2.4 GHz. It is designed to
communicate up to 1000m2 (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 1283 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.

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.

Warning:

type of End Device. Please refer to the user manual for the End Device to
determine which switches correspond to the NID.

The NID may be set with a different set of switches depending on the

DHCP and Defaults

Figure 4. Reset Button

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

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.

for more information on requirement to use DHCP.

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.

The ZW-REC includes all required hardware for mounting. To mount the ZW-REC position unit
where required. Mark the location of the top center of the unit. Refer to
drill the two screw holes as indicated. Use the included drywall anchors if needed and mount
the bracket so that the bracket clips are facing up. Align the back of the unit over the three
clips. When engaged slide downward and snap the unit in place.

•

When mounting the unit be sure to leave room on the top for the Antenna
and on the bottom and side for the cables.

•

Mount the unit away from any large metal obstructions such as posts,
catwalks or large machinery.

•

For best wireless range, do not co-locate the ZW-REC with other 2.4GHz
wireless equipment such as wireless routers or access points.

•

For best wireless range, elevate the ZW-REC and keep a direct line of sight
to End Devices.

INITIAL SETUP

This section guides you through how to setup the ZW-REC. Please do not power on any End
Devices until Initial Setup is complete. If the ZW-REC is being integrated into a deployment
with existing End Devices those End Devices may need to be reset once the ZW-REC is
configured.

3.1 Antenna Warning

Before powering up the ZW-REC ensure the supplied antenna is properly installed. Running
the ZW-REC without an antenna, or with an unapproved antenna, may cause damage to the
device and/or cause operation outside of regulatory compliance. Omega Engineering accepts
no liability and issues no warranty for devices operated improperly.

3.2 Choosing a Network ID

The Network ID (NID) selects which End Devices the ZW-REC communicates with. The NID is
selected using the DIP switches found on the back of the device. If this ZW-REC is replacing an
existing receiver in a wireless sensor installation, determine which NID is currently used and
use the same one. Refer to
NID.

In a new installation with only one Receiver, keeping the default NID of 0 is recommended. All
End Devices ship with a default NID of 0. If this installation requires multiple Receivers, ensure
that each Receiver has a unique NID.

Record the NID on the Net. Addr. label on the back of the ZW-REC for easy reference in the
future.

Section 2.2

to determine the correct DIP switch settings for each

3.3 Connecting to the ZW-REC

Power on the ZW-REC at by plugging in the supplied AC adaptor. The Green Power LED lights
up and the Blue Receive LED flashes. The ZW-REC performs an energy scan to determine what
the best RF frequency to transmit on is. Once the energy scan has completed the Blue LED will
remain lit. See

Connect the ZW-REC to your network or computer using an Ethernet Cable. When connecting
the ZW-REC directly to a computer a crossover cable is needed if the network adapter is an
older 10Base-T or 100Base-TX type. A normal cable can be used for modern 1000Base-T
network adaptors. The green Network Link and Activity LEDs light up once a connection has
been established.

Section 5.4

for more information on the energy scan.

Static IP Address

The ZW-REC comes configured from the factory with a default IP address of 192.168.1.200.
This address appears on a label on the back of the device. Bring up the ZW-REC web page by
navigating to http://192.168.1.200 in your web browser.

DHCP/DNS

In installations where a static IP address is undesirable, an IP address can be automatically
assigned using a DHCP server. See

Section 5.2

for more information.
