CAP2100 GUI board (B42AXR06):
1. Encoder color coding as follows:
2. Check for 2 red dots and one green dot with an "M" on solder side of the panel board. They indicate the
following modifications:
Red dot 1:
Red dot 2:
Green dot:
Green dot "M":
Populate L2, L3, L4, L5, L6 with 0.1uF /50V caps (CL10B104KBCN)
Float ground on LCD display (open case and insulate 4 ground pads)
3. Check standoff between panel board and display, must be the right size and board must be straight not
crooked.
4. Check that JP2 is shorted with juno jumper.
Retainer clips on ALL 10-pin connectors

Change R8 to RN55D1001
Removed resistor R9, cut GND_TRIG trace between trig-in and trig-outs (removed
ground from trig-outs, and jumpered normal ground from other side of R9 (end closer to
edge of board) to trig-out ground.
R1 changed to RN60D75R0

Remove R119, R121, R123,
Tie the case of the IR to the outside pin (ground) of the receiver with a jumper.
Remove Q3 and install change R92 to 71.5K.
Remove R38 and put resistor 5063JD56r from left side of C57 to left side of R38, Change
R92 to 71.5kohms 0.1%
Short pins 4 and 5 on the PIC.
Lift pin4 of U24, run jumper from lifted pin4 to pin9, short pad of pin4 to pin5, cut trace from
pin5.
NOTE: this last mod requires ARM software version 1.05 or higher (otherwise it smokes the
