( PULSE ). The specification sheet for the device connected to the remote power jack should contain information as to
which type of signal it requires, and if it is a pulse, the minimum pulse duration.
The output signal of the remote power jack does not need to be delayed since its activation is by the user via either the
hand held remote or front panel
REMOTE button.
Buttons 2 , 3 and 4 have exactly the same functionality as button 1 , except that they apply for the three MAIN POWER
jacks on the rear panel.
The MAIN POWER 1 jack is activated immediately upon exiting the standby mode (pressing the front panel or the
hand held remote POWER button), the MAIN POWER 2 jack is activated X seconds after exiting standby and the
MAIN POWER 3 jack is activated X times 2 seconds after exiting standby. X represents the time, in seconds, that is
set by pressing button # 5 – MTIM , or Main [Delay] Time. This is useful for sequencing the turn on of high power
components such as amplifiers. Further to this, when the Casablanca III is put into standby, it can be set that all of the
MAIN POWER jacks turn off simultaneously or sequenced off in the opposite order as they were activated.
Sequencing is accomplished by setting SEQ (button # 6 ) to ON or OFF . By setting the SEQ parameter to ON , the
user is activating the power down sequencer.
If the type of output for any of the rear panel power jacks is set to PULSE , the duration (in milliseconds) of this pulse
can be set by the user, by selecting the A-D button and using the LEVEL UP / DOWN buttons to change the pulse
duration.
*The current limiting resistor is 33 ohms, 0. 5W. This means that the more current a device to be triggered draws, the
more the output voltage gets reduced. The formula is : Output voltage =12 – (I x 33), where I = the current draw from
the triggered device, in Amperes. Refer to the device’s manual for this information. The Casablanca III’s maximum
output current is 100mA, which, by using the above formula, means that with a 100mA draw, the output voltage will be
8.7 volts, although most triggered circuits have virtually no current draw.
Clear Balance (Temporary Settings Control)
Any changes in the
BALANCE menus are, by default, temporary. That is to say that when an INPUT SELECT button
is pressed or the Casablanca III is powered down/put into standby, any changes will be reset to zero. This feature has
an override, which is set by pressing button #
4 in the first SETUP / GLOBAL page (figure 52 on page 67) and set to
OFF . When this parameter is set to OFF , changing inputs or powering down/going into standby will maintain all
BALANCE menu settings.
RS232
In the first SETUP / GLOBAL page, press button # 5 to access the RS232 sub menu shown in figure 56.

Press button # 1 ( BAUD ) and use the LEVEL UP / DOWN buttons to select the Baud rate that matches that of the
RS232 controller. The factory default value is 115.2K
The Casablanca III can be set to automatically send changes to the RS232 port. This can be done by selecting a
“Status Level”, which means if any Casablanca III parameter changes, that level's bytes will be sent to the port. This is
useful for monitoring master level, input and the like when the user has access to both the Casablanca III and the
touch-panel controller, to keep them synchronized.
Button # 2 ( ECHOS ) [Echo Status] allows the user to enable or disable the output of data to the RS232 port and, if
enabled, determine which level, or pre-determined group of bytes it outputs. Setting this value to OFF disables any
parameter change information from being output to the RS232 port.
