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.

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

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.

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

END DEVICE READINGS AND CONFIGURATION

Figure 7. End Device Readings (Populated)

This section details how to view, log and chart data received from End Devices. Turn on and
configure any End Devices now. Confirm that all End Devices are set to the same Network ID
as the desired ZW-REC. Also ensure each End Device has a different Device ID selected. If an
End Device is running, it needs to be reset after changes to the Device ID or Network ID.
Power on all End Devices now. If existing End Devices are running they may need to be reset
now.

Please refer to the End Device user manual for detailed instructions on setting Network IDs
and Device IDs.

The ZW-REC can display a NID chart to help configure zSeries and zwSeries End
Devices. Refer to

4.1 End Device Readings Page

When logging into the ZW-REC the End Device Readings page is displayed. The readings page
shows the current sensor data from all connected End Devices. When an End Device turns on
it enters active scan mode and search for a receiver. When the ZW-REC is found the Blue
Wireless Link Indicator on the End Device flashes once and turns off. The Link Indicator flashes
again each time a reading is transmitted. Once an End Device finishes connecting to the ZW­REC it is automatically added to the reading page.

Section 5.1

for more information.

The readings page shows the End Device ID, Name and Status followed by readings from any
connected sensors. End Device Status will change from Good to Lost if an End Device misses
three transmissions in a row.

The Sequence Number is transmitted by the End Device and incremented with each
transmission. An increasing sequence number shows that the web page is getting fresh data

12 | P a g e

from the End Device. The Sequence Number resets to 0 after it reaches 255.

Figure 8. End Device Settings

The Last Update field shows the last time a new measurement was updated on the webpage.
The webpage update rate is set at the bottom of the page. This changes how often the
webpage checks for readings but does not change how often End Devices transmit new
readings. The Last Update field uses the time retrieved from the local system.

By default, End Devices are displayed sorted by Device ID and up to 10 End Devices are
shown. Use the
number of entries can be changed using the drop down menu in the upper left. Up to 100 End
Devices can be displayed at once.

When dealing with a large number of End Devices it may be useful to filter which ones to

4.2 Changing End Device Settings

Connected End Devices and Sensors can be configured by clicking the settings icon on the
right side of the page, on either the Readings or Status Page. A list of user adjustable
parameters including the Sensor Name, Update Interval, and Sensor Offsets are shown. Other
parameters may be shown based on the connected sensor. Please refer to the Sensor User
Manual for sensor specific instructions.

General Settings

The End Device Name can be up to 16 characters long.
Names are displayed on the web pages with the Device
ID to help differentiate between End Devices.

The name cannot contain any of the following
characters: ; = ( ) < > “ &

The Update Interval is the frequency End Devices
transmit readings. By default, most End Devices send one
reading every 10 seconds. The update interval greatly
effects the battery life of End Devices. The shorter the
update interval the shorter the battery life will be.
Shorter update intervals also increase the chance of RF
Interference when there are multiple End Devices. It is
recommended that the update interval be set only as
short as required for optimal battery life. Please refer to
the End Device user manual for more information on
battery life.

Each End Device can have multiple sensors. The Sensor
Offset is used to make adjustments to each
measurement as needed. The offset can be positive or
negative and contain up to 4 decimal places. The End Device will round each reading to the
local sensor accuracy so extra decimal places may not be reflected in the final reading. If the
End Device has a display, the offset will also be reflected on the display.

To change a value in the General section, type the desired value into the dialog box and press

that subnet.

•

If you change the IP address it is highly advised that the label be updated.
Remove the IP Address sticker and write in your new IP address in the area
provided.

Host Name, DHPS and DNS Server

The default host name for the ZW-REC is zwrec**** where **** are the last 4 digits of the
MAC Address. See

The ZW-REC can be accessed using its host name instead of its IP address. To use this feature
DHCP must be with a Domain Name Server (DNS).

Enabling DHCP on the ZW-REC allows a DHCP Server to automatically assign an IP address.
Checking the DHCP box overwrites the static IP settings. Be sure to also enter the address of
the associated Domain Name System (DNS) server when DHCP is enabled. A DNS Server links
the device’s host name to its IP address. If DHCP is turned on but a DNS server is not available,
it may be difficult to locate the correct IP address to connect to the ZW-REC.

APPENDIX A Certificate Configuration

Figure 21. Certificate Configuration

The ZW-REC is configured with a default SSL
certificate not issued by a Certificate Authority
(CA). The non-verified certificate causes most
web browsers to display warning messages. A
CA-issued SSL certificate can be used instead
and will not trigger warnings. This may make
for a better user experience.

Omega cannot provide a CA signed certificate
because a private encryption key is required
to be stored on the device. Distributing a
private encryption key compromises its
security. Always protect your encryption key.
A stolen encryption key can be used to spoof
your presence on the internet. Omega is not
responsible for and does not have any
obligation towards the process of obtaining a
certificate or protecting your encryption key.

APPENDIX C RF Topics

Figure 29. 2.4GHz Spectrum Map

This section discusses some topics to ensure the best RF coverage range.

C.1 RF Channel Selection

The 802.15.4 wireless standard uses 16 RF channels numbered 11 through 26. Each channel
has a bandwidth of 2MHz and channels are separated by 5MHz. When the ZW-REC is powered
on it automatically searches for the quietest channel to use for communications. You may also
choose to manually select your RF Channel. (See

Manually selecting an RF channel may be necessary if there are running multiple receivers in
one area. While multiple Receivers can coexist on the same RF channel, selecting different
channels is recommended. Using separate RF channels will reduce potential interference
between systems. This is particularly true for large deployments.

Wi-Fi networks may also create interference with the ZW-REC. Wi-Fi networks operate on
fixed frequencies with channels occupying 20MHz or 40MHz of bandwidth. While there are
many Wi-Fi Channels there are only a few non-overlapping channels that are generally used.

Figure 29

commonly used Wi-Fi Channels in North America and Europe. If the Wi-Fi channels currently
in use are known, select an 802.15.4 channel that does not overlap with it to reduce
interference.

Section 5.4

)

C.2 Signal Strength Indicator

Signal Strength is displayed as a percentage, for each end device, in the End Device Status
Page. This indicates how well each End Device can hear the ZW-REC. The ZW-REC and most
end devices have a receive sensitivity of -96dBm or better. In most cases this means that a
Signal Strength reading of 15% to 20% is reasonable for maintaining reliable communication.

The ZW-REC transmits at a power of +9.5dBm. Certain End Devices are lower power than the
ZW-REC so the received signal strength is higher at the End Device than it is at the ZW-REC.
For these End Devices the Signal Strength indicator needs to be higher for reliable
communications. For these low power devices, a signal strength of at least 25% to 30% is
recommended.

Figure 30

measured in dBm which is a logarithmic term. For every 10dBm increase in receive power the
actual power is increased by 10 times. For Low Power End Devices, the received power at the
ZW-REC may be 10dBm, or more, lower than indicated by the Signal Strength field. Take this
into account when evaluating link quality for low powered devices.

C.3 Maximizing Range

Under favorable conditions the ZW-REC can achieve a line of sight wireless link distance of up
to 1000m. Generally, most indoor applications will not be able to achieve these distances
although steps can be taken to maximize range. Ensure the Receiver and End Device are
located away from large obstacles and other RF sources such as Wireless Access points and
microwave. Keep objects clear of the zone between the End Device and Receiver. Metal
objects, walls, and cubical partitions in particular will all significantly reduce the signal
strength.

The antenna provided with the ZW-REC is a dipole. Care must be taken in the positioning of
the antenna to achieve the best possible range. The gain of the antenna is lower along the
axis of the antenna. Do not point the ZW-REC Antenna in the direction of an End Device.
When possible, The ZW-REC antenna should be parallel to the End Device antenna. If the End
Device does not have an external antenna the longest dimension of the End Device itself
should be parallel to the antenna of the ZW-REC.

Keep the antenna away from dense or metallic structures. Metallic structures should be kept
away by at least 0.8" (2 cm), although 2.4" (6 cm) is recommended. Objects too close to the
antenna may screen the ZW-REC from End Devices. Reflections off of nearby objects can also
cause destructive interference reducing received signal strength.

For long distance connections the Receiver and the End Device should be elevated to keep the
signal from being attenuated by the ground. Elevate each device by at least 0.6 meters above
the ground for each 100 meters or separation. It is best to keep this same clearance distance
to walls, ceilings and other obstructions as well.
