Do not install the pins in the headers! Remove the pins from the headers!
If the round
pins are provided on black plastic headers, they should be removed and individually
installed to allow more visible light around the displays. Hold each header upside down
on the sharp corner of a bench, piece of wood, etc. Grab the back of the pin with a
needle nose plier, and push down hard. The pins will pop out.
Install a round pin onto each pin of LED1-LED6. Use masking tape to hold the displays
in place. Position the display board upside down on a flat surface and solder all pins.
Solder U4 to the back of the display board. Note the direction. Again follow the above
procedure to install surface mount parts.
Install LED7-LED10, the colon LEDs. The short pin goes toward the top of the display
board. Align the colon LEDs so the top is even with the front of the alphanumeric
displays.
Step 3
– Final Assembly
Install two, 10mm standoffs into the holes on the bottom of the main board on the side
with the buttons, using two screws.
Install two standoffs into the holes on the bottom of the main board on the front, along
with the short side of the 90 degree brackets. Put the screw into the short side of the
bracket, then through the main board, and into the standoff.
Plug the display board into the main board, and install two screws and nuts to secure it
to the brackets. The display board should be in front of the brackets.
This completes WordClock-1 assembly. Refer to the User Manual for setup and operating
instructions.
