WARNING: CMOS Battery Damage
Replace your system’s CMOS RAM battery only with the identical CR-2032 3V Lithium-Ion coin cell (or equivalent) battery type to avoid risk of personal injury or physical damage to your equipment. Always dispose of used batteries according to the manufacturer’s instructions, or as required by the local ordinance (where applicable). The damage due to not following this warning will void your motherboard’s manufacturer warranty.
Perchlorate Material- Special Handling May Apply.

ATTENTION: Incorrect BIOS Setup
If you do not know how to handle BIOS setup or how to set it up properly, it is strongly advisable that you do not modify any of the settings than otherwise instructed in the User’s Quick Start Card. Even a seemingly small incorrect adjustment or modification in the BIOS setup can render your system unstable or unusable. The incorrect BIOS setup is not covered by your motherboard’s manufacturer warranty.

WARNING: Electrostatic Sensitive Device (ESD)
Static electricity can easily damage your motherboard and will void your motherboard warranty. Keep the motherboard and other system components in their anti-static packaging until you are ready to install them. Touch a grounded surface before you remove any system component from its protective anti-static packaging. Unpacking and installation should be done on a grounded, anti-static mat. The operator should be wearing an anti-static wristband, grounded at the same points as the anti-static mat. During configuration and installation touch a grounded surface frequently to discharge any static electrical charge that may have built up in your body. Avoid touching the components when handling
the motherboard or a peripheral card. Handle the motherboard and peripheral cards either by the edges or by the peripheral card case-mounting bracket.
WARNING: Misplaced Jumper Damage
Incorrect setting jumpers and connectors may lead to damage to your motherboard and will void your motherboard warranty. Please pay special attention not to connect these headers in wrong directions. DO NOT change ANY jumprs while the motherboard has the power!
Application Notes:
Please read the following application notes before proceed with the system setup and/or OS installation:

Windows 10 Drivers Installation
It is recommended to load the ECM-3455J drivers with following sequence:
1. Install “Intel INF Driver”.
2. Install “Intel Video Driver”.
3. Install “Realtek LAN Driver”.
4. Install “Realtek Audio Driver”.
5. Install “Intel TXE Driver”.
6. Install “Intel Serial IO Driver”.
7. Make sure there is no exclamation mark shown for any device under Windows “Device Manager”.
NOTE:
1. If any of the driver listed above can’t be installed, you may update Win10 to the latest version through
Windows Update by connecting ethernet cable to one of two ECM-3455J onboard LANs.
2. If the Intel video driver is installed, and the video installer shows again after the system reboot, just close it.
3. Win10 user may download “Intel Graphics Command Center” app from MS Store in order to access the Intel video settings directly.
Boot Mode
The default boot mode is set as “UEFI”. If you want to switch the boot mode to “Legacy”, it can be changed through BIOS option “Boot”->”Boot Mode Select”. Then save and exit BIOS once in order for the new boot mode to take effect.
Video Support
1. Under UEFI boot mode: The HDMI and LVDS will provide video signal simultaneously.
2. Under Legacy boot mode: Only either HDMI (default) or LVDS provides video signal. (if LVDS panel is attached, please disconnect the HDMI monitor connection to ECM-3455J board in order for the video signal to be switched to the LVDS panel).
Dual Role (OTG) Support
The “Port 0” of “F_USB2” header (the USB port pin 2, 4, 6, 8, 10, right next to the SATA header) can support Dual Role when:
1. Set the BIOS option ”Advanced”->“XDCI Support” to “Device Mode”, then save and exit BIOS.
NOTE:
1. Dual Role is recommended to be used under Android or Linux OS with its own Dual Role driver support.
2. Win10 doesn’t provide Dual Role driver support.
DP Support (Available with ECM-3455J eDP version ONLY)
For eDP version of ECM-3455J:
1. Connect the eDP panel signal cable to “LVDS” header.
2. Connect the backlight control cable to “BACKLIGHT” header.
3. There is no eDP BIOS related setting required.
PXE Boot
A. In “UEFI” Mode:
1. Under BIOS option “Boot”->”Boot mode select”; change it to “UEFI”.
2. Under BIOS option “Advance”->”Network Stack Configuration”:
a. Change “Network Stack” to “Enabled”.
b. Enable “Ipv4 PXE Support”.
3. Save and exit BIOS.
4. After system reboot, enter BIOS again.
5. Under BIOS option “Boot”->”UEFI NETWORK Drive BBS Priorities”, set the desired PXE LAN port as “Boot Option #1”.
(NOTE: a. LAN1 (the one next to USB ports) is described as “PXE iP4 Realtek PCIe GBE Family Controller (LAN1)” under BIOS “UEFI NETWORK Drive BBS Priorities” list.
b. LAN2 (the one next to audio port) is described as “PXE iP4 Realtek PCIe GBE Family Controller (LAN2)” under BIOS “UEFI NETWORK Drive BBS Priorities” list.)
6. Press “ESC” key to get back to “Boot” menu.
7. Under BIOS option “Boot”->”Boot Option #1”; change the 1st boot device to the desired PXE LAN that selected under step 5.
8 Save and Exit BIOS.
9. The system will be prompted with message “Check media presence….” and establish link with PXE server.
B. In “Legacy” Mode:
1. Under BIOS option “Boot”->”Boot mode select”; change it to “Legacy”.
2. Save and exit BIOS.
3. After system reboot, enter BIOS again.
4. Under BIOS option “Boot”->”NETWORK Drive BBS Priorities”, set the desired PXE LAN port as “Boot Option #1”.
(NOTE: a. LAN1 (the one next to USB ports) is described as “Realtek PXE B02 D00” under BIOS “NETWORK Drive BBS Priorities” list.b. LAN2 (the one next to audio port) is described as “Realtek PXE B03 D00” under BIOS “NETWORK Drive BBS Priorities” list.)
5. Press “ESC” key to get back to “Boot” menu.
6. Under BIOS option “Boot”->”Boot Option #1”; change the 1st boot device to the desired PXE LAN that selected under step 4.
7. Save and Exit BIOS.
8. The system will be prompted with PCIe version and establish link with PXE server.
The “SPEAKER” Header
The “SPEAKER” header supports 4 ohms/ 2W speaker.
The MIC support under Win10 The rear audio port supports “headset” (the headphone with lineout + microphone) with 3 black rings (OMTP or CTIA types).
Here is the installation procedure for MIC support under Win10 environment:
1. Install BCM provided ECM-3455J specific Realtek Win10 audio driver.
2. When the headset is plug-in to ECM-3455J rear audio port; the system will be prompted for the selection of “Headset” or “Headphone”, Please select “Headset” ONLY.
3. The Realtek HD Audio Manager will be prompted and displays the “Microphone” icon. The microphone on the plugged-in headset is ready to use.
