APPENDIX A – QUICK START GUIDE
This guide shows you how to quickly connect the EA-104 to your network and to PDA devices with CE5.0,
PPC2003, Windows CE.NET4.1/4.2, and Windows Mobile 5.0 OS.
Included in this box are:
•EA-104 USB server
•Power Adapter
•Ethernet cable
Before you start ensure that:
1. You have at least one computer and a network
2. You have TCP/IP networking properly configured on your computer. Please refer to Windows help for
more information.
3. You have an Ethernet network and a spare port available on your Ethernet switch
4. You have a PDA device with a USB interface connected to the available network
Once you have all of this in place move to Step 1 below.
1. Connections
Connect the Ethernet cable into the 10/100 uplink port (WAN) on the rear of the EA104. Connect the
Ethernet cable into your switch or hub. Connect the power cord to the back of the unit and plug the power
supply into the wall socket or AC power source. The power LED should blink slowly on the front of the unit -
there is no on/off switch. The Network LED should now light on the front of the unit if the link is established.
The EA104 default mode is DHCP. In a DHCP network environment EA104 will obtain one IP address from
the DHCP server after power-on. In a non-DHCP environment, the system administrator must set up an
enclosed DHCP network by accessing the EA104 configuration using the browser-based AdminTool as
described later in this guide. The power-on process takes about 25 seconds. The EA104 can be reset to
factory settings by pushing and holding the Reset Button for eight seconds or longer.
.
2. PDA connections
Now connect your USB PDA devices to the available USB ports on the back of the unit. Please refer
“Appendix B – Window Mobile 5.0 device” for connecting multiple WM5.0 devices.

Clarinet Systems, Inc. //www.clarinetsys.com Page 12
EA104 has four USB host ports that simultaneously connect up to four PDAs through their USB ports to an
Ethernet network. Each connected PDA can perform server synchronization, Internet browsing, and file
transfer.
3. Clarinet Systems DevFinder (optional)
Download “Clarinet Systems DevFinder” from http://www.clarinetsys.com and launch the DevFinder
application to locate the EA104 device and find its IP address. Choose the Default Search range as
Broadcast, which is suitable for small networks. If your network is large, choosing Range Search to define
and limit the search range is preferable.

APPENDIX B – WINDOW MOBILE 5.0 DEVICE
Firmware V02.00.00 dated 8/22/2007 supports simultaneous operation of multiple WM5.0 mobile
devices such as PDAs and smartphones, which was unsupported in earlier firmware versions.
In order to support multiple WM5.0 devices, the WM5.0 device must be set up as follows:
A) Configure the WM5.0 device for RNDIS Sync mode (the default mode)
This can be configured at Settings\Connections\ActiveSync Mode\RNDIS Sync Mode. If there is no
Settings\Connections\ActiveSync Mode, the WM5.0 device is likely set at default mode.
If you do not see Settings\Connections\ActiveSync Mode but want to confirm the settings:
1. Go to the mobile device manufacturer’s website and download the latest ROM/firmware to update to your
WM5.0 devices.
2. Check the device manufacturer’s software section webpages and determine if there is ActiveSync Mode
Switcher/Changer available for download.
3. Once you download and install the firmware and/or application, the ActiveSync Mode Switcher can be
found at Start->Setting->Connections.
B) Use Clarinet Systems’ “EtherUSB Client” application to enable multiple WM5.0 connections to
EA104. (You will only need to do this once for each device.)
EtherUSB Client offers the following functions for WM5.0 devices:
Display device’s current setting
Input USB IP Group value used by EtherUSB EA104
Assign one ID from 49 choices for each WM5.0 device
Apply Setting
Restore Default setting
Download “EtherUSB Installer” from http://www.clarinetsys.com/en/product-ea104.htm to a PC and use
ActiveSync to install it to a WM5.0 device.
Install “EtherUSB_Installer” to WM5.0 device:
Connect your WM5.0 device to a PC via ActiveSync and click on Explore,

Clarinet Systems, Inc. //www.clarinetsys.com Page 16
Or,
In ActiveSync, go to Tool->Explore Device. This will open a new explore window.
Drag and drop the EtherUSB_Installer.cab file to My Documents folder on the PDA.
Go to the PDA and launch File Explorer under Start menu.
Go to My Documents folder and click on EtherUSB_Installer.cab file to install the application on your PDA.

Clarinet Systems, Inc. //www.clarinetsys.com Page 17
You can use IR to beam EtherUSB_Installer to the other devices.
Activate WM5.0 device ready for EA104 connection:
1. Go to Start->Programs folder and launch EtherUSB Client (Fig 1 & 2).
2. Assign USB IP Group value (the value of “Network Settings – USB Ports” in AdminTool). No change
is needed if you use the default value 193.168.10.0 which is recommended. (Fig 3 & 4.)
3. Select one Client ID from 49 choices (under normal conditions, each device should be assigned one
unique Client ID). (Fig 3 & 4.)
4. Apply Setting so the device can now connect to EA104 along with other WM5.0 devices
simultaneously.
Fig1 Fig2

Clarinet Systems, Inc. //www.clarinetsys.com Page 18
Fig3 Fig4
Now WM5.0 device is ready for EA104 connection. Connection time is around 4 seconds for the device with
a unique Client ID. Otherwise, connection time varies from 10 to 40 seconds.
Note 1: When a WM5.0 device is plugged into the EA104, port the USB LED will flash. LED flashing means
the connection process is on-going. Important: During LED flashing, the user should not unplug a mobile
device from the USB port unless it takes more than 40 seconds. USB LED solid on after flashing means the
connection is established. LED off after flashing means the connection cannot be established, for example,
as caused by a duplicate ID conflict.
Note 2: If two or more EA104 units are installed in proximity to each other and there are
1. less than 49 WM5.0 devices to be used, it is recommended to keep the same USB IP Group value
for every EA104 (for example, keep default values 193.168.10.0).
2. more than 49 WM5.0 devices,
a. it is recommended to keep the same USB IP Group value for every EA104 and assign a
duplicate ID to those WM5.0 devices beyond 49. If an ID conflict arises from plugging in a
second device with the same IP, that device will be unable to make connection until its “twin”
is unplugged.
b. you can assign a different USB IP Group value to each EA104 (through “Network Settings –
USB Ports” page in AdminTool) and a set of WM5.0 devices. In this case, the connection
time is 4 seconds for the devices connecting to EA104 with the same USB IP Group value
and 10~40 seconds if connecting to EA104 with a different IP Group value.
You must use “Restore Default” to restore original settings in order to use the ActiveSync function between a
PC and a WM5.0 device, assuming original settings allow PC ActiveSync. You must also use “Apply Setting”
to enable any subsequent EA104 connection after “Restore Default”.
Restore the WM5.0 device’s original setting (the setting before changed by EtherUSB Client).
Go to Start->Programs folder and launch EtherUSB Client (Fig 1)
Select “Restore Default” (Fig 2)
Note: Please refer to http://www.clarinetsys.com/en/product-ea104.htm for latest WM5.0 Devices Support.
