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 OIC 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 and three.
Jumpers J6 and J8 are for consoles with the touch screen
option. Setting the jumpers to J6 and J8 pins two and three
disconnects the MKM lead. A cable then connects the touch
screen controller board directly to the CPU port 1.
Jumpers J7 and J9 are reserved for future use and are not
used on the IIOIC42 console.

6. Carefully slide the module out of the multibus card cage.
7. Check the jumper settings on the new module before
assembling into the card cage.

ing or inserting modules into the card cage may result in
equipment failure.
