1. Setting up the GW-2200 Series
Before updating the firmware, please ensure that the network settings for both your host computer and any
GW-2200 series modules are correctly configured, or the update procedures via the Ethernet network may
not function correctly.
Step 1: Connect the GW-2200 series to the same hub or the same sub-network as your Host
PC, and attach a power supply to the GW-2200 series. Do not connect the GW-2200 series
to a router or directly to the Internet as this may cause the update process to fail.
Please refer to “Chapter 3-Connecting the Power and Host PC” in the GW-2200 Quick Start Guide for more
detailed information.
Download the Quick Start Guide.
Step 2: Install the eSearch Utility on your
Host PC, and then run the Utility to search
for any GW-2200 series modules
connected to the network.
Download the eSearch Utility.
Step 3: Configure the correct
network settings for the required
GW-2200 series module.
Please refer to “Chapter 4-Configuring Ethernet Settings” in the GW-2200 Quick Start Guide. If the IP address
settings do not work correctly, please refer to note1 (Page 18).

2. Firmware Update Procedure
The firmware update can fail when the computer has multiple network interfaces (e.g., LAN and Wi-Fi).
Therefore, enable only one network interface for updating the firmware, and temporarily turn off other
network interfaces, firewalls, and anti-virus software first.
2.1 GW-2200 Firmware Update
Two methods can be used to update the firmware: “Local Firmware Update” (traditional) and
“Remote Firmware Update” (TeamViewer). The Local Firmware Update method requires the user to
manually adjust the position of the Init/Run Switch and reboot the module in order to initialize the
firmware update. Refer to Section 2.1.1 “Local Firmware Update” for more details. The Remote
Firmware Update method allows the user to initialize the module via a web interface without
needing to adjust the hardware switch. Initialization via the web interface is useful when the module
is installed at a remote site and can be accessed via the TeamViewer application installed on a
remote PC. Refer to Section 2.1.2 “Remote Firmware Update” for more details.
2.1.1 Local Firmware Update
Step 1: In the eSearch Utility, click the “Search Servers” button to search the for any GW-2200
modules connected to the network . (The network settings of the GW-2200 module as described

3. Troubleshooting
3.1 Firmware update in BOOTP mode
If the module is not functioning correctly (e.g. there is no response to the search request, or if the
system LED is always displayed as either off or on), please download a new image of
the firmware from the ICPDAS web site and then update the firmware for the module using
the following procedure.
Step 1: In the eSearch Utility, select the “BOOTP”
item from the “Server” menu. A check mark
should be displayed next to the item after it has
been selected.
Step 2: Set the “Init Switch” to the “Init Mode”
position.
Step 3: Power-on and reboot the GW-2200 series
module and then click the “Search Servers” button to
search for the GW-2200 series at the same time. Note,
the module sends BOOTP messages about 5 seconds
when booting in Init Mode. If this step is not successful,
reboot the module and execute the search again.

Step 4: Right click on the name “BOOTP” and then select the “Firmware Update” item from the
popup menu.
Step 5: Refer to Steps 4 to 17 in “Chapter 2-Firmware Update Procedure” to complete the update
process. Note, the module will response with no IP address in the BOOTP mode. User has to assign
a valid IP manually in step 5 of page 3.
Step 6: After updating the firmware, disable BOOTP mode from the eSearch utility. By selecting
“BOOTP” item from the “Server” menu.

4. Additional Information
The code contained in the boot loader, which is used to update the firmware image, is not part of
the firmware it-self. This means that, the firmware can still be updated even if the built-in
firmware has been corrupted or does not exist. If the firmware update fails, simply execute the
update procedures again in BOOTP mode, as described in Chapter 3, and the update should be
successful.
The GW-2200 series obtains the IP address assigned by the user and retrieves the firmware image
through the utility program. Note that when updating the firmware, the GW-2200 series uses the
factory-default MAC address rather than any user-defined MAC addresses. The GW-2200 series has
a built-in flash protection feature that prevents any modification to the firmware stored in the flash
memory, before attempting to update the firmware, the “Init Switch” should be set to the “Init”
position and then the GW-2200 series can be powered-on and rebooted to disable the flash
protection. Since the flash memory
then becomes writable, the firmware
can be updated via the Ethernet
network.
Notes:
Note 1: If the IP address settings do not work correctly (e.g. there is no response to a ping
command), please contact your network administrator to obtain a valid IP address for the GW-2200
series module. ………………………………………………………………………………………………. back
Note 2: If the settings displayed in the IP address field of the firmware update window is incorrect
or invalid (e.g. IP address: 0.0.0.0), then a valid IP address must be manually specified for the
GW-2200 series in order to process the update operation. Please contact your network
administrator to obtain a valid IP address before proceeding.

Note 4: The “BOOTPREQ from MAC: xx-xx-xx-xx-xx-xx” message indicates there is a module with
the factory-default MAC address “xx-xx…” that is asking for the firmware to be updated. The update
process will not begin if you assign a user-defined MAC address in the firmware update window,
since the addresses do not match. If this situation occurs, repeat the update procedure and
manually enter the factory-default MAC address in the firmware update window, as described in
Step 5 on Page 4. The firmware update procedure is illustrated in the figure below.
