Cabling and Wiring
This chapter shows the attachments you can add to the main I/O
connector of your DAC-02 board. The main I/O connector of the DAC-02
is a 25-pin, D-type. Pin assignments for this connector are shown in
Figure 4-1.
Caution:
To avoid electrical damage, turn off power to the computer and
any attached accessories before making connections to a DAC-02 board.
