Assembling the MINI2440 or TenByTen6410 board into the Plastic Enclosure for MegaDisplay 7S

 

Thank you very much for your interest in this article and for taking your time.
We would like to show you how to assemble the MINI2440, MINI2440v2, or TenByTen6410 into Hiteg's Plastic Enclosure for MegaDisplay 7S.

 

Requirements:

• MINI2440, MINI2440v2 development board or TenByTen6410 development board
• Plastic Enclosure for MegaDisplay 7S or Plastic Enclosure with PCB Exchange Kit *
• MegaDisplay 7, MegaDisplay 7S, or exterior-sourced 7inch Innolux AT070 TFT panel
• Phillips screwdriver for M3 sized screws
• Have read and understood the Proper usage for LCD connectors
• Have read and understood the Proper usage for touchscreen connectors

 

*Note

Depending on your board you'll need either the Plastic Enclosure for MegaDisplay 7S compatible with the MINI2440, MINI2440v2 (06-PE7I-1), or the Plastic Enclosure for MegaDisplay 7S compatible with the TenByTen6410 (06-PE7I-2). 

Both compatibility choices for the enclosure effect only the enclosure's port hole sizes for the USB and SD-Card devices. The MINI2440, MINI2440v2 development boards use the larger variants (i.e.: USB type B receptacle, and SDcard receptacle), whereas the TenByTen6410 uses the smaller variants (i.e.: microUSB receptacle, and miniSD receptacle).

 

 

Suggestion:

Prior to installation, verify that your TFT display and development board work together.  Avoid using extreme force while screwing something in.

Step 1: Board into back shell

1.1 Place the back shell (VESA compliant shell) in front of you as shown in the image.

1.2 Insert on an angle the MINI2440, MINI2440v2, or TenByTen6410 development board with the RS232 (Serial) port first into the back shell on to the enclosure's four bosses. The development board should now be resting flat and snug into the back shell.

1.3 Using four of the 10mm long screws provided, carefully screw the board from its corner-most holes into the enclosure.

Verify that all ports are easily accessible.

Step 2: PCB Exchange Kit preparations

(Optional only for customers using the Plastic Enclosure and PCB Exchange Kit to convert one of their MegaDisplay 7's into a MegaDisplay 7S. If non applicable proceed to Step 3.)

2.1 Remove the nuts and screws of the MegaDisplay 7 to free and put away the white bezel. 

2.2 Disconnect both the 4pin touchscreen cable and the 40pin LCD FFC from the MegaDisplay 7's controller PCB. 

2.3 Remove the MegaDisplay 7's TFT display panel from its PCB while keeping in mind that if it is glued using double-sided tape to remove it with a slow and steady prying motion.  Put the old PCB away.

2.4 Briefly rub off any thick excess double-sided tape left on the 7inch TFT display panel.

Step 3: Display into front shell

3.1 Place the front shell (shell with 7inch display window cutout) face down in front of you so you can see its bosses to screw into, and with the button on the top right as shown in the image.

3.2 Remove the thin layer of protective film on the double-sided tape provided within the front shell to allowing the double-sided tape to stick. 

3.3 Carefully place your 7inch TFT display panel or your MegaDisplay 7S with its touchscreen facedown, and with its 4pin cable facing down, into the center of the shell.

3.4 (optional for Plastic Enclosure and PCB Exchange Kit users) Bring the unconnected end of the 100mm FFC from the 7inch TFT display panel through the larger hole of your new Slim PCB, and do the same for the 4pin cable through the smaller hole of your new Slim PCB.

3.5 (optional for Plastic Enclosure and PCB Exchange Kit users) Carefully connect both cables into their natural connectors on your new Slim TFT controller PCB (as seen in the above image). 

3.6 Using eight of the 10mm long screws provided, carefully screw the PCB into the front shell.

Step 4: Connecting the display and button to the board

4.1 If using the MINI2440, or MINI2440v2 development board, connect the provided 4pin cable to the button PCB's 4pin box header.  If using the TenByTen6410 development board connect the 3pin cable to the button PCB's 3pin box header.

4.2 Connect one end of the provided 250mm FFC (blue side up) to the only remaining 40pin connector on the 7inch TFT display controller PCB.

4.3 Connect the other end of the 250mm FFC (blue side up) to the 40pin connector on the development board.

4.4 Connect the 3pin (for the TenByTen6410), or 4pin (for the MINI2440, MINI2440v2), cable coming from the button PCB to the development board as seen in the relative image below.

 

Step 5: Sealing it off

5.1 Finally, place both of the surface and bass shells together (either way) and place it facedown (base VESA shell up) in front of you. 

5.2 Use eight of the 10mm long screws provided and carefully screw the enclosure shut.  

Congratulations!

Your MINI2440, MINI2440v2 or TenByTen6410 development board now has a new home.

From hereon you have the opportunity to go shopping for an MIS-D 75 VESA (75x75mm) compliant wall mount, which any consumer electronics store should be able to offer.

 

Troubleshooting:

If after you screw the enclosure shut and nothing is working, it is most likely that an FFC was connected on an angle, as they can be a bit tough to get it in straight.

If after you ensured that the FFC are properly connected and you still can't see anything, ensure that your MINI2440,MINI2440v2 is switched to LCD5V as indicated on the jumper close to the LCD connector.
