MULTIBUS KEYBOARD MODULE
•
Elsag Bailey Nomenclature - IIMKM01.
The Multibus Keyboard Interface Module (MKM) interfaces the key-
board and other operator input devices to the OIC12. The MKM is
mounted under the CRT mounting plate. There are four jumpers
on the MKM board to set for proper operation. J1 controls serial
port two (P9). Connecting the eight pins horizontally configures the
serial port as data communication equipment to the default shown
in Figure
. For DCE, data is transmitted from the MKM on pin
three of the connector and received from the connected device on
pin two of the connector. Connecting the eight pins for P9, vertically
configures the serial port as data terminal equipment (DTE). For
DTE, data is transmitted from the MKM on pin two of the connector
and received from the connected device on pin three of the
connector.
CAUTION
Failure to turn off the main power circuit breaker before remov-
ing or inserting modules may result in equipment failure.
