8 = UPPER EDGE
Press the 2 key to use the FADER to adjust the upper edge of the raster. Set the raster to the point where you
lose a row of pixels on the top, then just get it back.
2, 0 = LOWER EDGE
Press the 8 or 0 key to use the FADER to adjust the lower edge of the raster. Set the raster to the point where
you lose a row of pixels on the bottom, then just get it back.
5 = ASPECT RATIO
Press the 5 key to use the FADER to adjust the aspect ratio from 0.200(1:5) to 5.000(5:1). While adjusting, the
aspect ratio is shown on the KEYPAD DISPLAY in decimal form. Mechanical détentes are felt on the FADER at
the following aspect ratios: 1.000 (1:1), 1.333(4:3 NTSC, PAL), 1.778(16:9 HDTV), 2.000(2:1).
3 = LOCK-ON DELAY
Setup mode 3 is used to change the length of time allotted for M/E channels to lock-on to video input selections.
When a new input is selected and a transition is not in process, the input is routed into the not-on-program input of
the format converter. At the same time, the format converter configuration register for that input is recalled. An
internal lock-on delay timer is then set which inhibits a TAKE from occurring until the delay has elapsed. Pressing
KEYPAD keys 1-9 while in setup mode 3 changes the delay in increments of 50 milliseconds. Shorter lock-on
delays allow quicker switching between inputs, but have a higher likelihood of allowing synching glitches to show
up on the program output. The effects can be seen by setting up an auto take (see AUTO TAKE), and switching
between different inputs. Switching back and forth between the same 2 inputs will not work because no routing or
delay is used. When a delay is found that never shows any break-up on the program monitor with repeated testing
between all different video input formats, it is a good idea to use one higher to provide a safety margin. The factory
default for this setting is 5, or 250 milliseconds.
6 = STORE SETUP DATA
Setup mode 6 stores certain setup data in the EEPROM so it will be recalled whenever the ShowCase is powered-
up. Data stored includes global and M/E AUTO TRANS values, effects window size and position data for each
M/E, and PAN & ZOOM settings for each input.
7 = RECALL DEFAULT SETUP DATA
Setup mode 7 recalls factory default data into the same settings that are stored in the EEPROM in setup mode 6.
Use this setup when you don't want, or are having problems with, the setup data that is recalled during power-up.
If you want these default settings to be recalled during future power-ups, use setup 6 to store the default data in the
EEPROM, otherwise the old stored data will be used next time the system is powered-up.
COLD BOOT
A "cold boot" is performed by applying power while holding in the SEQ and TAKE keys (the outer 2 keys in the
lower row of the function key area). The word COLD shows on the KEYPAD DISPLAY. This causes the internal
CPU to execute program instructions only from the boot PROM, and inhibits the normal loading of software from
EEPROM memory. The SETUP key enters a self test mode that allows testing of all controls and indicators on the
panel. The next time the unit is powered-up, the normal application software will be loaded and run.
EEPROM is memory that holds its data when power is off, but can be written by the CPU. This memory is used to
store downloaded application software, certain setup data, and presets. Software updates are loaded into the
EEPROM by a connected PC running Windows 95/98/2000/NT and running the ShowCase configuration software.
If for some reason the unit will not run correctly due to corrupted data, and will not accept a software download from
a PC ("No Communication" showing on the PC), use the cold boot procedure to reboot. PC communication and
program download should always be possible following a cold boot.
