Shot Number Selection Lines
The external control interface has four lines used to
select a shot number (“SHOT - SEL - BIT” lines in FIG.
32, Connector #2, Pins #1, 2, 4, 5). The default for each
line is a “high” +24 VDC output. To select a shot, the
external control will need to ground a certain combina-
tion of lines to the Return line (Connector #2, Pin #3) for
at least 0.100 seconds to create a “low” signal for each
line. Each combination refers to one shot number from
Shot #1 to Shot #15. If all lines are “high” the shot
selected on the display module is used. See the follow-
ing table. See FIG. 34 on page 52 for a sample timing
diagram.
For system software versions 1.06.007 or later, the Shot
Number Selection lines cannot be used to select invalid
or undefined shot numbers. Attempting to select an
invalid or undefined shot number will be rejected.
