POWER REQUIREMENTS
The Remote Keypad Assembly does not require any input power.
REMOTE DISPLAY UNIT INTERCONNECT
The square pin terminals on the back of the
Remote Keypad Assembly will accept wiring either by wire wrap technique or by use of a mating 10-pin female connector, with one end pin position not used. The matrix assignment for each pin is as follows: o o o o o o o o o <— pins

OPERATIONAL DESCRIPTION
When any key on the keypad is pressed, the
"row" and "column" lines for that position are shorted together to produce a "closed" switch condition. If the "KEYBOARD ENABLE" input to the RDU is active, the RDU scan recognizes this as a keypress input. For RDU response to keypresses, refer to the "RDU KEYPAD
FUNCTIONS" section of the User Reference
Sheet for the RDC.
When the RDU is performing self-diagnostics, pressing any key on the keypad will interrupt the exercise of the alphanumeric (upper) display of the RDU, and the XY coordinate of that key position will be displayed (refer to the "SELF-DIAGNOSTICS" section of the User
Reference Sheet for the RDU).
