Jumper J4 allows the option of disabling the power supply
out-of-tolerance (OOT) signal to reset the MKM module. Set the
jumper to J4 pins one and two to disable the OOT signal. Set
the jumper to J4 pins two and three to enable the OOT signal.
Factory default is to disable OOT on all OIS consoles.
NOTE: The two digital outputs are open collector type which sink up
to 250 milliamps. The two digital inputs are rated at up to 250 milli-
amps (future).
Jumper J5 must be set to pins two to three.
Jumpers J6/J8 and J7/J9 are for consoles with the touch
screen option. For IIOIS42X1 and IIOIS42X2 consoles (upper
or lower monitors), one touch screen card (TS1) is used and is
mounted on the component side of the MKM board. Jumpers
J6 and J8 on the MKM board control the touch screen option
for single monitor consoles and pins one to two should be jum-
pered. For IIOIS42X3 consoles (dual monitors) an additional
touch screen card (TS2) is mounted to the solder side of the
MKM board for the touch screen option. Jumpers J7 and J9 on
