Configuration
To set the DIP-switches, use a small flathead screwdriver to move the DIP-
switches to the ON or OFF position as described in the following sections.
6.1.1 Self Address DIP-Switches
The Self Address DIP-switch determines the position of a
VS-808xl unit in
the sequence, specifying which
VS-808xl unit is being controlled, when
several
VS-808xl units are controlled by a PC or serial controller. Set the
Self Address on a
VS-808xl unit via DIP-switches 1, 2, and 3, according to
Table 6.
