Chroma I/O PCB (old type)
CAUTION
This board can only be used when the analyzer also has the old type Single Board
Computer PCB (identified by a toggle Reset switch).
This board, part number 3528515-2, has two jumpers which are mutually exclusive. When there is
only one Chroma I/O PCB in the analyzer, or the board is used as Chroma I/O PCB #1 in a
simultaneous dual detector analyzer, the jumper will be located between the terminals of JP1 (see
Figure 8-37). This jumper is part of the printed circuit trace on this version of the Chroma I/O PCB.
Jumper trace is on the
circuit side of the board.
Figure 8-37. OLD CHROMA I/O PCB JUMPERS
When a second Chroma I/O PCB is used, Chroma I/O PCB #2 must have the JP1 jumper trace cut
and a jumper installed between the JP2 terminals.
Chroma I/O PCB (new type)
This board, part number 802A028D-_, has six jumpers, JP1 through JP6 (see Figure 8-38).
