HARDWARE SETUP

Before plugging the DC-820B into your system, make sure all jumpers on the
card are correctly set according to instructions outlined in section 1.1. Also
take care that the SCSI ID number (0-6) of each SCSI device is set properly
for the host adapter (ID 7) (if necessary, check the user manuals for the
respective devices). Correct cable connections and termination are also nec-
essary for the adapters to function flawlessly. Refer to the following section,
Board Layout and Jumper Setting, for the exact location and setting of
jumpers.

SCSI Device Activity LED Indicator (JP1)

JP1 is used to indicate the activity of SCSI devices controlled by the DC-
820B and should be connected to the cable leading to HDD LED on the front
panel of your system case. This LED also flashes some diagnostics codes
right after power-up. Refer to Appendix C for more details.
