2.2 Step 1: Connecting the DSK to Your PC
Follow these steps to connect your DSK board to your PC:
1) Turn off your PC’s power.
2) Connect your parallel printer port cable to the parallel communication port
(LPT) on your PC. This port can be identified by its size and pin type, which
should be the female matching equivalent to the DSK. (RS232 ports which
use DB25 connectors use the opposite pin configuration).
3) Plug the parallel printer port cable into the DSK DB25 connector.
4) Plug 7–12 Vdc or 6–9 Vac power supply into the DSK power supply con-
nector. See Figure 2–1 for details.

Note:
Some manufacturers of plug-in cards may also use DB25 connectors that
appear to be of the same type. If this is the case, be sure to check the PC
configuration thoroughly before continuing.
