4.2.7.1 Wed-based Configuration
To use the wed-based interface to configure the wireless EM405D, open a web browser and enter
the device’s IP address as the web address to open. This will launch the main web page of the
configuration utility. Navigate through the pages of the web interface making the necessary
changes to the configuration. When finished making changes in any given section, click on that
pages “Apply” button to apply the changes. Some changes may require that the wireless
Ethernet interface be rebooted, in which case the user will need to re-connect to the device.
4.2.7.2
Restoring Factory Defaults
Similar to the wired version, the wireless version of the EM405D has a dilemma in which the
carrier must be connected to a network in order to configure its network properties. The
dilemma is made worse in the wireless version by the fact that there is no physical connection to
the device and there are additional configuration settings that must be known in order to connect
to the device, such as the network mode, security settings (WEP, WPA), channel setting, and the
SSID. If the EM405D configuration is not known and thus the user cannot connect to the carrier,
it is possible to reset the configuration settings to known defaults using a small push-button
switch found on the inside the EM405D enclosure.
CAUTION: The following procedure requires opening the EM405D
enclosure and applying power while the PCB is exposed. Use
extreme caution when attempting to perform the procedure as
to not damage the carrier or any of its components.
To restore the factory defaults:
1) Turn power Off.
2) Remove the front panel cover by removing the two screws located at the sides of the
panel. Do not remove the screws located on the bottom of the enclosure.
3) Slide the top cover of the enclosure forward exposing the rear portion of the PCB.
4) Locate the tiny push button switch near the Ethernet device (bottom right hand corner of
the PCB when the carrier is oriented as shown in Figure 3).
5) Using a finger or a tool, such as the eraser end of a pencil, press and hold the button.
6) While holding the button down, turn the device On.
7) Continue holding the button pressed until the amber colored LED on the back of the
Ethernet device flashes a 1-5-1 sequence.
8) Once the 1-5-1 sequence is complete, the device has been reset to its factory defaults and
the user may release the button.
9) Re-assemble the EM405D by sliding the top cover back into place and re-installing the
front panel.
