PC-280 Board
(3) Remove the three (3) 2-56 Phillips head screws securing the PC-280 mounting brackets
to the top plate. These screws will be in line with the PC-280 LEDs that protrude through
the top plate. Carefully lift the board out of the top panel. See Figure 5.3.
(4) Using the Phillips-head screwdriver, remove the three (3) PC-280 mounting brackets
from the old circuit board and reinstall them on the new circuit board. Ensure that the
mounting brackets are installed so that the clearance areas machined into the
mounting brackets are towards the PCB assembly. This will prevent electrical shorts
between the mounting bracket and electrical traces on the PCB.
(5) Place the new PC-280 board so that its connectors and LEDS protrude through the top
panel. Loosely install the three (3) 2-56 screws to secure the PC-280 mounting brackets
to the top panel. (To ease reassembly, they will be tightened after installing the
electronics back into the module case.)
(6) Reinstall any previously installed wiring harnesses on connectors P1, P3, and P6 of the
PC-280 board. Ensure proper pin 1 orientation when installing these connectors.
(Pin 1 of the ribbon cable has a red stripe while pin one of P1 will contain a square
solder pad on the PC-206.)
(7) Install the module electronics into the housing, ensuring that the alignment posts in the
module's bottom panel align with the holes in the PC-280 mounting brackets. Ensure that
there are no conductors from the P1 harness pinched between the top plate and the
housing. Ensure that the top plate gasket is properly installed. Install the screws that
secure the top panel to the housing. Tighten the three (3) screws attached to the PC-280
mounting brackets.
(8) Test your scanner to ensure proper operation.
