1.0 Introduction
The NetWave industrially hardened wireless Ethernet transmission link from ComNet can be
configured through the embedded User Interface as a Client or as an Access Point. This point-to-
multipoint model allows multiple Ethernet endpoints to be connected to a central Access Point.
Up to 15 endpoints can be linked to a central access point. This single radio model was designed
for high throughput point-to-point or multi-point applications and comes with an integrated 19
dBi, 17º beamwidth antenna. The NW7[E] supports up to 240 Mbps throughput using MIMO
technology. The units can be powered by an 802.3af/at PoE compliant device or through a sold-
separately PoE injector with the second Ethernet port serving as an IEEE802.3at power source.
The NW7 is FCC certified and the NW7E is ETSI, DFS and TPC certified.
This user manual is a guide for the NetWave NW7[E] wireless Ethernet device as well as the
NWK7[E] preconfigured kits. ComNet NetWave Wireless offers OpenWRT with the most advanced
Qualcomm Atheros 10.1.x wireless drivers. NetWave now includes a new user-friendly LuCI
web interface for configuring the device. OpenWRT is an extensible GNU/Linux distribution for
embedded devices. It is built from the ground up to be a full-featured, easily modifiable operating
system. It is powered by a Linux kernel that's more recent than most other distributions. LuCI is a
free, clean, extensible and easily maintainable web user interface for embedded devices. It has
high performance, small installation size, fast runtimes, and good maintainability. The units come
configured for either point to point or point to multipoint applications.
This manual contains detailed operational and configuration information not covered in the quick
start guides.
This guide applies to the following models:
NW7 - Industrial Multipoint, FCC Version, User Configurable
NW7E - Industrial Multipoint, ETSI Version, User Configurable
NWK7 - Industrial Multipoint Kit, FCC Version (Includes NWK7_AP and NWK7_CL)

2.0 Point to Multi-Point
These individual units allow the user to configure for either multipoint access point or client operation.
There is a MAC address lock feature that can be enabled through the user interface but is not enabled
by default. The NW7[E] includes a 19dBi 17° internal antenna. See the ComNet website for the
latest information regarding antenna support. Preconfigured NWK kits do not support point-to-
multipoint topologies.

4.0 Cabling Requirements
Shielded CAT 5 or better should be used for all out of plant Ethernet connection and should
be properly grounded through the PoE AC ground. Industrial grade shielded Ethernet cable is
recommended to help prevent ESD damage commonly experienced with outdoor installations.
Visit www.comnet.net/comnet-products/cables
5.0 Hardware Installation
5.1 Outdoor Ethernet Gland Installation
There will be at least one cable gland included with each outdoor enclosure. Below is an image of
the individual parts of the gland with an Ethernet cable routed through.
Note: The split rubber washer allows a pre-terminated Ethernet cable to be used.
Once the cable has been routed through the weather connection, and the RJ45 connection has
been made, screw in the gland into the housing making sure it is tight enough for a water tight
seal. Push the split rubber gasket into place and loosely screw the cap that goes over the rubber
washer.
Once the gland is tight in the housing, tighten the outer nut/cap making sure the rubber seal
squeezes and seals the Ethernet cable to the gland as shown below.

Connect one end of an RJ-45 Ethernet cable to the LAN OUT port of the Power Injection
Module (PIM) and the other end to LAN of the access point – as shown below.
Note: Maximum length of the RJ-45 CAT5 cable is 90 meters.
Connect the RJ-45 Ethernet cable attached to the PIM to a network device, such as a switch or
to the configuration PC. Then plug the power adaptor to an AC power outlet and power plug
into the socket of the PIM – as shown in the diagram below.
Note: DC Passive PoE input for the NW7[E] and NWK7[E] is 48 VDC.
A. Connect one end of an RJ-45 Ethernet cable to the OUT
port of the CNGE1IPS or other 35W PoE Injector (sold
separately) and the other end to LAN of the access point.
Maximum length of the RJ-45 CAT5 cable is 100 meters.*
B. Connect the RJ-45 Ethernet cable attached to the PoE
Injector to a network device, such as to a switch or to the PC
you will use to configure the access point.
C. Connect the power adaptor to the main electrical supply
and the power plug into the socket of the PoE Injector .
PoE power input: Passive PoE (range 36 to 48 VDC).
The units can also be powered by a suitable IEEE 802.3af/at
PSE device such as a PoE switch or injector.
D. A Drip Loop is recommended as additional precaution
against moisture entering the Access Point housing.
* Up to 200mW radio. For higher power radio upgrade to higher rating
power adapter.

7.0 Quick Configuration
1. Connect an Ethernet cable from the port labelled as IN on the power Injection Module to
either a laptop or a PC LAN port.
2. Connect the second Ethernet cable from the OUT port on the Power Injection Module to the
NetWave LAN port.
3. Apply 48 VDC to the Power Injection Module with the provided power supply. You should
notice the green LED illuminate in the Power Injection Module and the power LED on the
NetWave unit.
4. Set the IP address of the laptop being used to configure NetWave to static and the subnet to
192.168.10.x /24 subnet.
5. Point the browser to 192.168.10.101. This is the default address.
For preconfigured kits (NWKX_AP and NWKX_CL) point the Browser to 192.168.10.100 for the
Access Point or 192.168.10.101 for the Client.
6. A login prompt will pop up. Enter:
Username admin
Password admin
7. Select the NETWORK » WIFI tab and set the desired network settings.
Select Apply & Save
Note: This will be the network address for the NetWave web server. It is not necessary to set to
the same subnet as the operating network but it is recommended.
8. Select the NETWORK -> WIFI tab and set:
• Wireless mode – Set to AP or Client
• Country code – Only required if setting up the NW7E (ETSI) model
Note: It is the user’s responsibility to ensure that the correct country is chosen. ComNet
accepts no liability for incorrect equipment set up.
• Output RF power – if received signal strength is greater than -40 dBm, it is recommended to
reduce RF TX power
• Set SSID – if changing from the default setting
• Channel Spectrum Width – May want to reduce to 20M from the default 20/40M if the 5GHz
spectrum is crowded
• Wireless Security – if changing from default settings
• Select Apply Settings
• Select Save
Note: NW7 and NW7E Multipoint nodes will need to have the Wireless Mode set to either AP or
Client (default is Client). And the IP addresses will need to be all set to different addresses
(default address is 192.168.10.101). Once this is done, all the clients will connect to the
multipoint AP with all other setting kept at default.
