- SELECTION 1ST/2ND BOARD -
DESCRIPTION
The pin-strip (j7) is a three-terminal selector placed on the
expandable boards (LARGE, SMALL EXPANDABLE and
SMALL NON-EXPANDABLE).
The figure on the right shows the two selections possible on the
pin-strip.
If your system requires two boards then it is necessary to
distinguish between them. Therefore select '0' (by means of the
pin-strip) on the first board, and '1' on the second board.
If you need just one board, set the link to '0'.
