10 Galaxy II Operating Manual
Ideally, the detector should effectively sense darts striking
anywhere on the web surface, even the lightest dart.
Optimum sensitivity will vary from location to location
depending on the environmental circumstances. For
instance, if a machine is in close proximity to a loudspeak-
er which gives off vibrations, or possibly a dance floor,
sensitivity may have to be decreased to compensate for the
interference.
To adjust the sensitivity, connect the ground lead on your
multimeter to a ground test point on the mainboard. Touch
the plus lead to the middle of the 2 pins (see Figure 9a).
The default setting is 4.75Volts. Adjust as needed for each
location’s needs. Test by tapping the catch web until you
have achieved the desired results.
C. Target Interface
The switch matrix is connected to the mainboard via the 19
pins of J14. For troubleshooting purposes, it is important to
know which pins on J14 will give a particular score. This
information is given in the table below.
With the machine in setup mode. choose Darthead Test
from the Hardware Test Menu. After removing the switch
matrix connector from J14, pairs of pins can be shorted and
opened (quickly - less than 60 milliseconds) with a jumper
wire to simulate a dart hit. The score will not register until
the jumper wire is removed from one of the pins. This pro-
cedure can determine whether a scoring problem is caused
by the switch matrix or in the machine’s electronic circuits.
