connectors on the DH200s.
Figure 7
Tubing Routing Underneath PC-327 Board
Retain all of the existing connecting cables for use with your new PC boards. The two (2) boards
you have just removed will be replaced with three (3) new printed circuit boards. The PC-206 board
will be replaced by the PC-327 Analog Board. The PC-280 board will be replaced by the PC-322
Mother Board and the PC-323 Microprocessor Board. The PC-322 and the PC-323 will arrive
attached to one another and they will be installed as a single unit.
Installing the PC-327 Analog Board
(1) Remove the new PC-327 board from its shipping container, paying particular attention to
prevention of electrostatic discharge damage.
(2) Place the new board on top of the DH-200s with the connector pins on the same end as the
wiring harness. Route the one tube beneath the board. (See Figure 7.) Line up the gold pins,
and gently and slowly press to connect. Pay particular attention to the C1 and C4 tubes and
ensure they are not crimped or crushed between the PCB and the DH200s. (See Figures 7
and 7a.)
(3) Reinstall the two (2) Phillips-head screws to secure the PC-327 board.
