1. Setting up the PETL/t(P)ET Series
Before updating the firmware, please ensure that the network settings for both your host computer and any
PETL/t(P)ET series modules are correctly configured, or the update procedures via the Ethernet network may
not function correctly.
Step 1: Connect the PETL/t(P)ET series to the same hub or the same sub-network as your Host
PC, and attach a power supply to the PETL/t(P)ET series. Do not connect the PETL/t(P)ET series
to a router or directly to the Internet as this may cause the update process to fail.
Please refer to “Connecting the Power and Host PC” in the PETL/t(P)ET series Quick Start Guide for more
detailed information.
Step 2: Install the eSearch Utility on your Host PC, and then run the Utility to search for any
PETL/t(P)ET series modules
connected to the network.

Step 3: Configure the correct network settings for the required PETL/t(P)ET series module.
Please refer to “Chapter 5-Configuring Ethernet Settings” in the PETL/t(P)ET series Quick Start Guide. If the IP
address settings do not work correctly, please refer to note1 (Page 10).

Step 5: Assign a valid IP Address and the factory-default MAC Address for the PETL/t(P)ET
series module. If this IP address is invalid (e.g. IP Address: 0.0.0.0) or a user-defined MAC
address is assigned. Refer to note 2 (Page 10) and note 3 (Page 11) for more details.
Step 6: Click the “OK” button.
Step 7: You are now ready to update the firmware. A Command Prompt windows will
be displayed the progress of the update.

Step 8: Set the “Init Switch” on the PETL/t(P)ET series module to the in “Init Mode”
position.
Step 9: Power-on and reboot the PETL/t(P)ET series module in “Init Mode” to initiate the
update.
Step 10: Confirm that the two MAC addresses (factory-default): “Waiting request from MAC
x.x.x.x” and “BOOTPREQ from MAC: x.x.x.x” are the same, as indicated below . If these
addresses do not match, the update cannot proceed, please refer to note4 (Page 11).

Step 11: Once the update is complete (i.e., when the progess indicator reaches 100%),
set the “Init Switch” in “Run/Normal Mode” position.
Step 12: Power-on and reboot the PETL/t(P)ET series module in “Run/Normal Mode” to
operate the module.
Step 13: Run the eSearch Utility and search for the PETL/t(P)ET series module again to
verify that it is functioning correctly. You may need to reconfigure the network settings
for the module after updating the firmware. Refer to Step 3 (Page 2).

Step 15: Click the “Web” button.
Step 16: Log in to the web configuration pages for the PETL/t(P)ET series (use the default
password “Admin”).
Step 17: Verify that the firmware version and date details are correct.

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, please refer to
Step 8 (Page 5) in Chapter 2.
Step3: Power-on and reboot the PETL/t(P)ET series module and then
click the “Search Servers” button to search for the PETL/t(P)ET series
at the same time. Note that the PETL/t(P)ET series module will wait
for about 5 seconds for the BOOTP search and firmware update when
booting in Init Mode. If this step is not successful, reboot the module
and 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 (Pages 3 to 7) in “Chapter 2-Firmware Update Procedure” to
complete the update process.
Step 6: After updating the firmware, disable BOOTP mode from the eSearch utility. By selecting
“BOOTP” item from the “Server” menu. The check mark next to the item should be removed after
it has been disabled. Note that BOOTP mode does not function when searching for a module in
Normal mode.

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 PETL/t(P)ET 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 PETL/t(P)ET series uses the
factory-default MAC address rather than any user-defined MAC addresses. The PETL/t(P)ET 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 PETL/t(P)ET 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
PETL/t(P)ET 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
PETL/t(P)ET series module in order to process the update operation. Please contact your network
administrator to obtain a valid IP address before proceeding.

Note 3: When updating the firmware, the factory-default MAC address is used rather than the
user-defined MAC address. Thus, the MAC address (user-defined) displayed in the firmware update
window may not be the one required. If this is the case, the factory-default MAC address should be
manually entered into the MAC Address field, or restore the MAC address to the factory-default
settings via the web configuration pages.
………………………………………………………………………………………………………………………………… back
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.

Note 5: BOOTP (Bootstrap Protocol) is defined in RFC-951 and uses UDP ports 67 and 68.
Note6: TFTP (Trivial File Transfer Protocol) is defined in RFC-1350 and
uses UDP port 69.
