4. “ERR-MSG CONFLICT”. This message
will be displayed to indicate that more
than one drive attempted to assign a
menu item to the same menu item
number of the same default menu as
another drive. For example, Drive A
sends a default menu item to RDU 1,
menu item 3. Some time later, Drive
B sends a default menu item also to
RDU 1, menu item 3. When menu item
3 of RDU 1 is selected to be displayed,
the RDC will display “ERR-MSG
CONFLICT” on the RDU’s display to
warn of this error condition. This
error condition may be cleared by
removing the mistake in the PAC
programs and then reinitializing the
system. Another way to clear it is to
use the PCDU to create a menu item to
override the default menu item which is
in conflict.
RDU KEYPAD FUNCTIONS
General
A keypad connected to any RDU may
start a keypad sequence. However, once a
keypad sequence is started, it must be
completed before a keypress from a keypad
connected to a different RDU, or any push
button input, is recognized.
7
Up to 60 seconds are allowed
between keypresses. If a keypad sequence
has started and 60 seconds have elapsed
since the last keypress, then the keypad
sequence will be aborted. Furthermore, the
RDUs will revert to showing the messages
that were displayed previous to the start of
the sequence.
There is an auto-repeat function on
the keypresses. A keypad key will auto-
repeat at a rate of 6 presses/second if a key
is pressed for more than 0.5 second.
The keypad sequences allow for
number modification. On the first press of
a digit or a decimal point, the digit display
will blank and echo the keypress. Pressing
more digits will continue to echo the
pressed digit into the least significant
location while the previously entered digits
are shifted one significant digit to the left.
This may continue until the digit limit is
reached, and then no further digits will be
accepted until the number is entered or the
CLEAR key is pressed. The entered
number will be checked for errors (i.e.
number within range, number may be
modified, etc.) and then the appropriate
action will be taken. If CLEAR is pressed,
then the number that was displayed prior
to the start of the modification will be
shown.
The up and down arrows may be
used to increment or decrement a number.
Pressing the up or down arrow key on an
unmodified number will start a number
modification key sequence. The sequence
may be ended by entering the number or
pressing the CLEAR key. Pressing the up
or down arrow keys after a number has
started to be entered will stop the number
entry mode and increment or decrement
the displayed number. If a digit or a
decimal point key are pressed after
pressing the up or down arrow keys, then
the digit display will blank and echo the
keypress once again.
