Support for 802.11a/b/g/n WLAN (depends on W-Fi adapter)
Support for WPA/WPA2 WLAN encryption
Support for DHCP, static IP, and ZeroConf methods of IP address acquisition
Configuration through a browser or utility software
Support for Raw 9100 port and LPR printing methods
Panel button to print configuration information and change the configuration mode
LED indicators for connection, operation, and error statuses
1-2. Model Classification
IF2-WF01: 2.4GHz model (802.11b/g/n)
IF2-WFX2: 2.4/5GHz model (802.11a/b/g/n)
Remarks : Depending on the country, different Wi-Fi adapter may be used with IF2-WFX2 and model name
can be changed by that. (Ex: IF2-WF12 is for Japan.)

*The communication by “Ad-Hoc” does not work correctly in various cases due to various restrictions. If "Ad-Hoc"
does not work correctly, we recommend “Infrastructure”.
*The purpose of Ethernet port is to set up the WLAN interface board. And printing through the Ethernet port is not
taken into the consideration. Therefore, depending on the used environment, the Ethernet port may not work properly
for the printing.
*Only 2.412~2.462GHz is allowed to be used in USA. Available 2.4GHZ channels to choose for US users are only 1 - 11.
*Rules on the use of 5GHz band channels may vary according to different national laws.
Choose the 5GHz channel according to the law of the country to use this device.

2. Preparation
2-1. Installing the Printer
With an unobstructed view, the guideline transmission distance for the IF2-WFXX is approximately 30 m.
The transmission distance depends on the setup environment. This includes electrical interference from the
periphery, obstacles such as the printer, and the antenna location. Carefully consider these points before
installing the IF2-WFXX.
2-2. Using the Panel Button
The panel button on the operation panel is used to operate the IF2-WFXX.
Starting the WLAN Interface Board
Turn on the printer. The IF2-WFXX starts working approximately 20 seconds after the printer turns on.
Printing the WLAN Interface Board Configuration
Press the panel button. See 2-4, Printing the WLAN Interface Board Configuration (page 11) for details.
Switching to Setting Mode
Press and hold the panel button. The buzzer*will sound once, signaling a switch to setting mode.
・Setting mode enables the reading of the factory default settings.
・If there is no activity for three seconds in the setting mode, the buzzer*will sound once, signaling a return
to normal mode.
* Note that the buzzer will not sound if the IF2-WFXXis connected to the barcode printer. In addition, the
buzzer will not sound when the IF2-WFXX is used with the POS printer if the buzzer has been set to not
sound.
Restoring to the Factory Default Settings
Switch to setting mode, then press and hold the panel button. The IF2-WFXX will return to the factory
default settings.
When the operation is complete, the IF2-WFXX will restart automatically.
The settings are cleared so the wireless LAN must be configured again.

2-6-2. Example Settings
Use the WPS function and Configure Settings*
1) Connect the WLAN adapter to the IF2-WFXX.
2) Turn on the printer.
Confirm that the IF2-WFXX recognized the WLAN adapter. The WLAN adapter is recognized
approximately 20 seconds after the printer is turned on. The status indicator LED (green) starts flashing.
3) Hold the WPS button on the WLAN adapter for 1 second or more. The LED on the WLAN adapter starts
flashing.
If the adapter cover is being used, either open the cover or use a thin needle to press the WPS button
from the hole in the cover.
4) Start the WPS function of the access point.*
5) When the configuration is complete, the LED of the WLAN adapter changes to transmission status.
You can confirm that the configuration was performed correctly by pressing the panel button to print
out the configuration of the IF2-WFXX. See 2-4, Printing the WLAN Interface Board Configuration (page
11) for details.
* For the method to start the WPS function, see the manual of the access point. If the access point you
are using does not support the WPS function, perform configuration by using the “Configuring using
the Ethernet Adapter” method.
Configuring using the Ethernet Adapter
1) Connect the WLAN adapter to the IF2-WFXX.
2) Connect the Ethernet cable to the IF2-WFXX.
3) Turn on the printer.
After the printer is turned on and the IF2-WFXX starts, the IF2-WFXX will automatically obtain an IP
address from the DHCP server within 90 seconds. If an IP address cannot be obtained automatically, use
the ZeroConf function to allocate the IP address 169.254.XX.YY (XX.YY will differ by a setup
environment). Allocate the IP address while referring to 4-3, Setup Window (page 37).
4) Use the Web manager to configure the WLAN.
Configure the wireless LAN while referring to 3, Web Manager (page 17).

3. Web Manager
The IF2-WFXX is equipped with a Web manager function, which allows you to access the IF2-WFXX from a
web browser and check the status of the IF2-WFXX or change its settings.
3-1. Starting the Web Manager
1) Start a web browser.
2) In the address bar, enter the IP address and then press Enter.
Web Manager Window Layout
The Web manager consists of the following windows and tabs.
・The configuration window of the IF2-WFXX cannot be displayed if the network settings of your computer and the IF2-WFXX
differ. Ensure that the IP address of the IF2-WFXX matches the settings of your network.
・The IP address of the IF2-WFXX
can be confirmed by using the “Printing the Wireless LAN Interface Board Configuration”
method.
