3.6.1
LCD screen, keypad and compact switch
The crate is provided with a VGA-standard 7.7” colour LCD screen (640x480 resolution).
Four buttons (
+/- CONTRAST
and
+/- BRIGHT
), placed just below the screen, allow to
adjust the brightness and contrast of the monitor.
The keypad has 15 keys consisting of:
10 numerical keys from “
0
” to “
9
”,
the keys “
.
” and “
-
“,
the keys “
CMD
”, “
DEL
” and “
ACK
”.
The latter are the COMMAND, DELETE and ACKNOWLEDGE commands, respectively.
The COMMAND key allows to select the
Menu Bar
in the software interface running in
standalone operation or operation via terminal (refer to the
SY1527 User’s Manual
for
further details).
The DELETE key is the usual DELETE command of a standard keyboard.
The ACKNOWLEDGE key corresponds to the usual ENTER command of a standard
keyboard.
The keypad is used for the manual set-up of the channel parameters. They allow as well
to set the RS232 port configuration and the CAENET node address (the address of the
crate).
The compact switch, placed underneath the keypad on the front panel, can assume 8
positions plus the press action. The latter corresponds to the command SPACEBAR from
the keyboard.
The compact switch allows to move on the screen, by moving the lever toward one of its
8 directions, and to switch among the options available for the currently selected field by
pressing the lever.
For further details on the use of these control devices, please refer to the
SY1527 User’s
Manual
.
3.6.2
Interface Bus Section
The Interface Bus section has three slots: the first slot on the left contains the RS232
interface, a VGA-standard connector, a PS2 connector and the Ethernet interface; the
other slots can be used to host additional peripherals and, if not used, is covered with a
metal panel. For the exact location of these four connectors on the front panel please
refer to Fig. 3.5, p.30.
The RS232 interface allows to connect the system to an external ANSI VT100 (or
compatible) video terminal or to a standard IBM
TM
PC. The PS/2 connector allows to plug
in an external standard PC keyboard. These external components make easier the set-
up of channel parameters and, in general, allow more friendly control of the system.
For a detailed description of the default interfaces and its mechanical and electrical
specifications please refer to Section 4.3.3, p.38.
For a description of the peripherals which can be optionally housed in the two slot left
please refer to Section 3.5.4, p.29.
