1. Introduction LVDS flat panel displays are the building block for all modern flat panel monitors. The interface for such displays, however, is not standardized and, as a consequence, LVDS enabling on Intel Desktop Boards follow a specific implementation. 14.97 EMC certification is highly dependent on the system chassis.
3.1 Locations of connectors and headers 3.1.a Intel® Desktop Board DH61AGL Figure 1 shows the locations of the LVDS connectors and headers on the Intel Desktop Board DH61AGL. Figure 1: LVDS connectors and headers for Intel Desktop Board DH61AGL. 3.1.b Intel® Desktop Board DQ77KB Figure 2 shows the locations of the LVDS connectors and headers on the Intel Desktop Board DQ77KB. Figure 2: LVDS connectors and headers for Intel Desktop Board DQ77KB.
3.1.c Intel® Desktop Board DH61AG Figure 3 shows the locations of the LVDS connectors and headers on the Intel Desktop Board DH61AG.

3. Connectors 3.1 LVDS connector The LVDS panel connector is a 40-pin (dual-row) shrouded white header, supporting video data, clock, and EDID signals, as well as panel logic power. This connector/cable ships already built into the AIO chassis and does not need to be purchased separately. Table 2: 40-pin LVDS connector signals Pin Signal name Pin Signal name 1 ODD_Lane3_P 21 N/C 2 ODD_Lane3_N 22 EDID_3.
4. Onboard headers 4.1 Panel voltage selection header Intel Desktop Boards with LVDS interface connectivity provide configurable voltage levels for powering a wide range of display panels. The AIO specification requires the panel voltage to be 5V. Table 4 shows the signals for the panel voltage selection header. Table 4: Panel voltage selection header signals Pin Signal name Description 1 Key No pin 3 12 V 12 V option 5 Key No pin Pin 2 4 6 Signal name 3.3 V LCD_VCC 5V Description 3.
For Intel Desktop Boards DQ77KB and DH61AG, the backlight inverter power header supplies a voltage level of 5V or 12V by setting the 1x3 selection header with a jumper. Table 6 shows the signals for the backlight inverter voltage selection 1x3 header.
Table 9 shows inverter voltage options that can be selected for Intel Desktop Board DN2800MT. Table 9: Backlight inverter voltage selection header options for Intel Desktop Board DN2800MT Voltage Pin configuration Notes 5V option 12V option Vin option (wide range system voltage input) 4.3 This is the default setting for Intel Desktop Board DN2800MT. Backlight-off and mute header Intel Desktop Board DH61AGL includes a backlight-off and mute header.

ECS: There is an extra cable for 1x2 “monitor off” feature in ECS G11 which is not defined in the AIO Design Guide, so the Intel boards don’t support this feature. 4 5 Gigabyte: There is an extra cable for “Wi-Fi LED” feature introduced by Gigabyte, not defined in the AIO Design Guide. There are no plans to add the “WiFi LED” feature to Intel boards. Gigabyte: Intel Desktop Board DN2800MT board rev -600 is not compatible with the single-channel LVDS cable provided with the Gigabyte AEBN (18.5”) chassis.
Push the cover to the top There are metal tabs that hold the back cover to the inside chassis pan. To remove the back cover, push the cover towards the TOP. Lift the back cover Once the cover has been pushed up about ½ cm, it can be lifted straight up. If the thermal solution is installed in the chassis, then remove it from the chassis.

6.2 Installing the desktop board Install the I/O shield Install the half-height IO shield that shipped with the DH61AG board. Push both ends in with your thumbs. Thermal solution attaches to the board The Mitac 650 chassis does not include a back plate; instead the thermal solution is attached to the board and the chassis through four screw standoffs, which are screwed into the chassis pan. AIO Integration with Thin Mini-ITX Intel® Desktop Boards – v3.
Install processor and memory It is easier to install the smaller components (processor, SO-DIMM memory, mSATA SSD drive, wireless card) onto the board BEFORE installing the board in the AIO chassis. Install mini-PCI expansion cards Install the Wi-Fi module and mSATA SSD drives into the half-length and full length mini-PCIe slots respectively, and secure them with the retention screws. AIO Integration with Thin Mini-ITX Intel® Desktop Boards – v3.
Integrate the board Move all the wires away from the board area, and raise the metals tabs of the I/O shield before you install the board. Make sure no metal tabs are going inside the back panel ports. Insert the motherboard at an angle, aligning all the back panel ports into the IO shield. Lay the board flat and screw in the four screws.
Internal speakers The Mitac 650 AIO has 3 watt/4 ohm stereo speakers inside which get powered directly from the board. Connect the 4-pin white connector near the ½ length PCIe expansion slot to the internal stereo speaker connector which is 1x4-pin, shrouded. Wireless antenna The Mitac AIO has two wireless (Wi-Fi) antennas pre-installed (white and black) with cables routed to the board area. Connect the cables’ gold contacts to the wireless module.
Touchscreen interface If your Mitac 650 chassis supports an optical touchscreen interface, the touch interface is implemented as a single 1x5 USB header. Plug this cable into a single USB header (shown below next to the processor socket on the Intel Desktop Board DH61AG board). Flat panel backlight power and brightness Insert the 8-pin shrouded panel power and brightness connector to the red connector next to the LVDS port. The connector is keyed so can only be plugged in one way.
LVDS connector Insert the flat silver ribbon cable with a 40-pin LVDS connector into the board’s LVDS port on the top surface of the board. Note: there is another similar looking port on the bottom side which is an eDP* port (embedded DisplayPort*.) To ensure the connector is all the way in, use a screwdriver head to push in both sides of the connector. Front panel connector Plug the front panel chassis cable to the board’s front panel header.
Webcam and digital MIC In the Mitac 650 AIO chassis, the webcam and digital MIC are implemented as a single USB device with a 1x5 pin internal USB header connector. Plug it into a regular 4-pin USB port (next to SATA data ports). Slim optical drive Connect the combo SATA power and data cable for the slim optical drive. AIO Integration with Thin Mini-ITX Intel® Desktop Boards – v3.
SATA power cable A SATA power cable ships with the Intel Desktop Board DH61AG board and will power both the hard disk drive (or SSD) and an optical drive. The L-shaped connector connects to the board. SATA data cable A SATA data cable ships with the Intel Desktop Board DH61AG board and should be used for the hard disk drive (or SSD). Connect the L-shaped connector to either of the two SATA data ports on the board. AIO Integration with Thin Mini-ITX Intel® Desktop Boards – v3.
Installing a 3.5” hard drive If you are using a 3.5” drive instead of an mSATA SSD: slide the drive into the cage and then secure it with the included four screws. Place the drive assembly on the chassis pan at an angle so it slides under the back plastic panel. Align the screw holes for the drive cage and then screw in the two screws provided to hold the cage to the chassis pan. Plug in a 3.5” hard drive Plug the SATA power and SATA data cable coming from the motherboard to the back of the drive.
Integrate the thermal solution Apply the thermal interface material (TIM) to the processor. Place the heatsink into position, aligning the board and chassis attach at the same time. Then screw the four thermal solution screws in a Z-pattern. Note: the thermal solution goes under the chassis edge (circled) Integrate the processor blower Finish the thermal solution integration by securing the heat exchanger to the chassis with one screw. Then place the blower in the chassis, aligning its three screw holes.
Plug in the blower Plug the 4-wire cable from the blower to the white processor fan header on the board next to the SATA power port. The fan is PWM-controllable and has a fan tach signal output wire. The fan speed ranges from 1180 – 3380 RPM.
