these steps.

main power circuit breaker.
2. Remove the required cables.
3. Loosen (do not remove) the two screws in the left and right
card retaining brackets.
4. Slide the left and right card retaining brackets out of the
way to permit the module removal tabs on the cards to pass.

IIMKM02A Multibus Keyboard Module
The multibus keyboard interface module interfaces the key-
board and other operator input devices to the OIS console.
There are nine jumpers on the MKM board to set for proper
operation (Fig.
). Refer to Table
for jumper settings.
Jumpers J1 and J2 control serial ports P8 and P9.
Jumper J3 resets the multibus card cage when the MKM
watchdog timer circuit times out. Factory default is no reset on
time-out.
Jumper J4 allows the option of disabling the power supply
out-of-tolerance (OOT) signal to reset the MKM module. Fac-
tory default is to disable OOT.
Jumper J5 must always be set to pins two to three.
Jumpers J6/J8 and J7/J9 are for consoles with the touch
screen option. For IIOIS43X1 and IIOIS43X2 consoles (upper
or lower monitors), one touch screen card (TS1) is used and is
mounted on the component side of the MKM board. For
CAUTION
Failure to turn off the main power circuit breaker before remov-
ing or inserting modules into the card cage may result in
equipment failure.
ATTENTION
Si l'on omet d'eteindre l'interrupteur du circuit d'alimentation
principal avant de retirer les cartes ou de les inserer dans le
porte-cartes, l'equipment pourrait faire default.
