Display And Keyboard - Dk - Philips SM40 Instructions For Use Manual

4. OPERATING AND PROGRAMMING THE SM40 SYSTEM
4.2 Display and Keyboard
A programming tool, containing a keyboard for user key assignment and a display which shows the
sequence of programming. Mounted in the front panel of the rack unit.
Users of the SM40 Public Address Distribution System are able to program and make changes to the
functions of their system, quickly and easily, with the aid of the Display And Keyboard. This is a simple
programming tool comprising a 24 key keyboard and a 2x40 character lcd display which shows the sequence
of programming.
SM40 KEY FUNCTIONS
0-9 Numeric keys to select call station number,
user key number, priority level, attention
signal tone number and program numbers as
listed in the main menu.
Moves the cursor 1 position to the right
when routing Call Stations, Attention Tones,
pre-recorded messages or Auxiliary sources
(background music players, etc.) to amplifier
inputs; each amplifier input representing a
loudspeaker zone. Also used for
programming free-programmable relays.
This is called :
"MATRIX/RELAY PROGRAMMING".
Moves the cursor 1 position to the left
during matrix/relay programming.
Moves the cursor to the beginning of the
following lock of 8 amplifier inputs during
matrix programming.
Moves the cursor to the end of the previous
block of 8 amplifier inputs during matrix
programming.
Switches the output, indicated by the cursor
1
during matrix programming, to the "ON"
position. Routing the call station or auxiliary
source being programmed to the desired
amplifier input.
Switches the output to the "OFF" position,
0
cancelling routing of the call station or
auxiliary to the amplifier input indicated by
the cursor.
Switches all outputs to the "ON" position,
routing the source being programmed to all
1
amplifier inputs.
Switches all outputs to the "OFF" position,
cancelling all routing of the source being
0
programmed.
Mute Switches the output, indicated by the cursor,
to the -10 dB mode when it is desired to
attenuate the volume of background music
during an announcement, rather than muting
it.
This function is only available on every fourth
input of the Matrix card.
Break If pressed during auxiliary programming, will
return user to the main menu for the next
programming sequence (in this case Call
Station programming) without storing any
new information.
During Call Station programming, 'BREAK'
returns the user to the previous stage in the
program (e.g. after "PROGRAM USER KEY:
(1-10)", it will go back to "PROGRAM CALL
STATION: (1-16)" without storing any new
information.
Enter Enters numerical inputs into the memory and
moves to the next program stage, or at the
end of a program sequence; to the main
menu ready for the next program.
A While the system is in its run mode, pressing
button A, displays the system status. The top
line of the display indicates where Call
Stations, Signal Generator Cards, Digital
Message Cards and auxiliary sources are
connected to the matrix. The bottom line
indicates which user key is currently being
pushed, and which SGC is producing a signal
or which DMC is relaying a message.
B In the Installer programming Menu, button B,
is used to set the I/O RS232 serial interface
communication parameters with an external
computer. The parameters are as follows:
Baud rate, stop bits and parity. See
Chapter 5.13 on the I/O PCB.
C With the system in programming mode,
button C is used to couple or uncouple the
Keysets (KST)s, as described in the Input
Card, see Chapter 5.3.
