Notice the pattern of push-buttons on the controller, and the pattern of holes in the front
panel. Match the patterns, and insert the controller push-buttons through the holes in the
front panel. Wiggle the controller a bit as you gently attempt to insert it into the front
panel.
You’ll most likely note that mis-alignment of some of the LEDs stops the controller from
fully seating on the mounting standoffs and stops the LEDs from protruding evenly
through the front panel.
Make a note of which LEDs are misaligned. Remove the controller, and carefully adjust
those LEDs as needed to fit the front panel holes. You may have to repeat this procedure
3 to 5 times, but if you make small adjustments, everything will line up. It sometimes
help to wiggle the controller PCB when you’re close.
At some point, the controller will seem to pop through the front panel as all the LEDs
pass through the accompanying front panel holes. The forward edge of the LEDs extends
about 1/16” past the front panel. From this point on, it will be easy to remove and re-
install the controller PCB into the front panel as needed so long as you don’t bump into
the LEDs. The switches will guard the LEDs from most casual bumps as you continue the
next section’s assembly.
Install the Controller Power Wire
Identify the free-end of the red/black zip cord that comes from TB9 of the power supply
board.
Connecting 5V power and BGND to the controller
Done? (

Remove ¼” of insulation from the red wire.
Tightly twist the red wire strands, then tin them.
Remove ¼” of insulation from the black wire.
Tightly twist the red wire strands, then tin them.
Insert the tinned black wire from the IC side of the controller board into
TB1’s GND pin. Solder it on the switch side of the PCB.
Insert the tinned red wire from the IC side of the controller board into
TB1’s VCC pin. Solder it on the switch side of the PCB.
Trim the excess wire length of the black/red wire on the switch side of the
PCB.
Install the Controller PCB into the Front Panel
Locate qty 4 of the 4-40x1/4” zinc/plated (silver colored) Philips head sems screws (with
built in lockwasher) and a Philips head screw-driver.
Fit the controller PCB into the front panel. Check as before for even protrusion of all the
LEDs through the front panel.
Loosely install the 4-40 screws through the 4 holes in the corners of the controller PCB
into the mounting standoffs on the chassis front panel.
