SETUP GUIDE

United States FCC & Industry Canada rules
OQ7IHW 3656A-IHW
Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to
Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference
when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: The device
may not cause harmful interference, and it must accept any interference received, including interference that may
cause undesired operation.
This Class A digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe A est conforme à la norme NMB-003 du Canada.
CAUTION: Changes or modifications not expressly approved by the manufacturer could void the user’s authority to
operate the equipment.
Antenna spacing requirements for user safety
It is important to keep the radio's antenna a safe distance from the user. To meet the requirements of FCC part
2.1091 for radio frequency radiation exposure, this radio must be used in such a way as to guarantee at least 20 cm
between the antenna and users. Greater distances are required for high-gain antennas. The FCC requires a
minimum distance of 1 mW *cm2 power density from the user (or 20 cm, whichever is greater).
If a specific application requires proximity of less than 20 cm, the application must be approved through the FCC for
compliance to part 2.1093.
The installer of this radio equipment must ensure that the antenna is located or pointed in such a way that it does not
emit RF fields in excess of Health Canada limits for the general population; refer to Safety Code 6, obtainable from
Health Canada.
To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the
equivalent isotropically radiated power (EIRP) is not more than that required for successful communication.

1.5 Assign a Temporary IP Address
You need the IP address to log into the Radio Configuration/Diagnostic Utility
and configure the radio settings. If the radio is connected to a network with a
DHCP server, the radio may already have an IP address assigned to it.
If a DHCP server is not available, or if you prefer to assign a static IP address,
you can enter a temporary IP here. You will use the Radio Configuration /
Diagnostic Utility to assign a permanent IP address.
To assign a temporary IP Address
1 In IH Browser, click to select the radio.
Tip: If a radio listing does not appear in the window, open the File menu and choose Scan. If you
still do not see a radio listing, refer to Diagnostics and troubleshooting in the RLXIB-IHW User
Manual.

Important: The radio configuration is protected by a login password. The default password for the
radio is "password" (lower case, no quotes). To prevent unauthorized access to the radio
configuration, you should change the password when you have finished the initial configuration.
Note: The master is the "root" or top-level radio in a network. You must have at least one master
radio per network. For redundancy, you can assign more than one master to a network.
To configure a Master radio, make the following changes to the web
configuration form:
Radio Network Settings
Radio Name: Enter a unique name for the radio.
Select Master as the radio mode.
Network SSID: Assign a network name (SSID) of up to 32 characters. The
radio uses this name in all network references. All radios in a network must
have the same SSID.
Channel: Select a channel and frequency range for the network or accept the
default value. Network channels allow radios to avoid sharing a frequency
with other networks in the same location. The channel list indicates the
channel number as well as the frequency (2.4 gHz or 5 gHz).
Important: The RLXIB-IHW radio is supplied with a dual-band antenna that supports both
frequency ranges. If you use a different antenna with the RLXIB-IHW radio, you must choose a
channel and frequency range supported by the antenna.

September 16, 2009
Security Settings
Encryption Type: Encryption scrambles data so that only intended viewers
can decipher and understand it. Although "none" is an available encryption
type, ProSoft Technology strongly recommends encrypting all data sent and
received from every radio on your network, to help prevent your data from
being intercepted and decoded.
WPA phrase: To use WPA encryption on packets sent between the radios,
select WPA in the Encryption Type field. Next, in the WPA phrase field, enter
a pass phrase of between eight and 63 normal keyboard characters. This
phrase automatically generates an encryption key of 128 hexadecimal
characters. The default pass phrase is "passphrase" (lower case, no quotes).
For more information on encryption, see Security settings.
Because you must assign the same Network SSID and WPA phrase to the
repeater radios later in this procedure, you should write down the settings.
Note: Network SSID and WPA phrase are both case-sensitive.
Network SSID:_________________
WPA phrase:__________________
Radio Access Settings
If a DHCP (Dynamic Host Control Protocol) server is configured on your local
area network, the DHCP server can assign IP addresses automatically.
If you prefer to assign a Static (Fixed) IP address, select "Use the following IP
address", and then enter the IP Address, Subnet Mask and Default Gateway in
the Radio Access Settings area of the IH Radio web configuration form.
Important: If you intend to assign IP addresses manually, you must not duplicate an IP address
that is already in use on your network. If you are not sure what IP addresses are available, ask
your network administrator for assistance.

Before closing the Radio Configuration window, you must apply your changes.
Click Apply Changes to save your configuration and restart the radio.
Note: To discard your changes and start over, click Cancel Changes.
1.8 Adding and Configuring Additional Radios
At this point you should attach and configure any additional IHW radios you will
be using. Ensure that any new radios use a unique name, but the same Network
SSID as your master. The only difference in procedure will be in setting up each
additional radio. Instead of setting your additional radios as Masters, they should
be set as Repeaters or, more rarely, Clients, depending on their intended
purpose.

3.1 Check the Ethernet cable
If you connect a radio and the Ethernet LED does not light on the radio, there
may be a problem with the Ethernet cable. Verify that the cable is plugged into
the radio at one end, and to an Ethernet hub or a 10/100 Base-T Ethernet switch
at the other end.
Note: The RLXIB-IHW radio auto-detects the Ethernet connection type, and does not require a
crossover cable for direct connection to a PC.
3.2 LED display
The RLXIB-IHW front panel includes a set of LEDs that indicate the radio’s
status:
LED Description
Power This green LED indicates that the radio has power.
RF Transmit This yellow LED indicates RF transmission.
RF Receive This green LED indicates RF reception.
Serial If this green LED is lit, the serial cable is connected. If this LED is flashing, a
serial packet is being transmitted or received (The serial port is not available in
the first release of the radio).
Ethernet If this green LED is lit, the Ethernet cable is connected. If this LED is flashing, an
Ethernet packet is being transmitted or received.
Signal Strength If only one of these three LEDs is lit, then the radio is linked. If two LEDs are lit,
the radio’s signal strength is fair. If all three LEDs are lit, the signal strength is
good.
If a radio is configured as a master, the middle light of the three Signal Strength
LEDs will always be on, and the bottom Signal Strength LED will always be off.
The top LED on the master will flash if any radios are linked to this master.

After you first plug in the power cable and Ethernet cable to the radio, the
Power/Status LED should be green, meaning that the radio has power. If the
Ethernet LED is green, then the Ethernet connection is working. The RF Transmit
and RF Receive LEDs should blink.
All three LEDs will blink just after the radio links to the Master’s signal but before
it has been fully authenticated. Normally you will see this last only a few seconds.
If it lasts longer or never turns solid it usually means the encryption keys are not
correct.
3.3 Retrieve the default password
If you forget your password, you will be unable to change the radio settings. You
can retrieve the default password to use the software again, but you will lose all
the settings you programmed before. To retrieve the default password and return
the radio to its default settings, follow these steps:
1 Turn off power to the radio.
2 Locate the reset button hole, located to the left of the power connector.
3 Insert the end of a paperclip or similar device into the hole to press the reset
button.
4 Turn on power to the radio, and hold down the reset button for 30 seconds.
5 The radio will be reset to its default settings, including the password. You
should now be able to log in using the default password, which is "password".
3.4 Starting Over
If necessary, you can always restore the default settings that your radio was
shipped with by opening the Radio Configuration/Diagnostic Utility, logging into
the radio, and clicking on the Factory Defaults button. This will remove all
changes you have made to the radio configuration, including addressing,
naming, and security settings.
