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 you wish to
monitor. Only switches 5 – 8 are used. Do not use switches 1 through 4.

Some End devices only support NIDs 0 – 7. Other End Devices may require a PAN
ID for configuration. The PAN ID corresponding to each NID is listed in

DHCP and Defaults

The set of 4 switches near the Ethernet port allow you to do some 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.





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.

PART 3: INITIAL SETUP

This section guides you through how to setup your 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 your 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.

10 | P a g e

Figure 3.1 – https Warning

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 ZW­REC is replacing an existing receiver in a wireless sensor installation, determine which
NID is currently used and use the same one. Refer to
correct DIP switch settings for each 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 ZW-REC

Power on the ZW-REC at this point 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
information on the energy scan.

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.

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 https://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

https Warning

The ZW-REC is configured with a default SSL certificate that is not issued by a
Certificate Authority (CA). Most web browsers provide a warning page when you
connect to the ZW-REC informing you the SSL certificate is not trusted. This is normal
and it is safe to procced. Click “Continue to this website” to bring up the ZW-REC

Host Name, DHPS and DNS Server

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

You may access the ZW-REC using its host name instead of its IP address. To use
this feature you must first enable DHCP and connect to a Domain Name Server (DNS).

Enabling DHCP allows your 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 your Domain Name Server (DNS) when you enable DHCP. A DNS links
your device’s host name to its IP address. To use a DNS, enter its address in the DNS
box. If DHCP is turned on but a DNS is not available it may be difficult to locate the
correct IP address to connect to your ZW-REC.

Once you have made your desired changes press the
change. A network reset is required before the new settings take effect. Once the
device is reset you navigate to https://HOSTNAME to access the ZW-REC. Please note
that it may take a few moments for your DNS server to recognize your receiver.



It is very important to communicate with the network administrator in order to

understand DHCP and its existing configurations on the host server, before
enabling DHCP on the Receiver.



On Windows servers where DCHP and DNS are separate functions it is very

important to configure the DHCP server to communicate with the DNS in order
for the Host Name to be correctly identified.



If you cannot access the ZW-REC using its Host Name, please contact your

network administrator to make sure the DHCP server and DNS are linked
together.

APPENDIX F: RF Topics

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

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

Section 3.6

You may want to manually select an RF channel if you 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.
occupied bandwidth of the most commonly used Wi-Fi Channels in North America and
Europe. If you know what WiFi channels are currently in use, select an 802.15.4
channel that does not overlap with it to reduce interference.

)

Figure F.1

shows the 802.15.4 channels mapped against the

Signal Strength Indicator

Signal Strength is displayed as a percentage, for each end device, in the
Diagnostics 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 F.2

Receive power is 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.

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 ZW­REC.

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.
