MODEL 209
TALENT CONSOLE
Tally Output 1; 0 volts DC is present on Tally Output
2. When Tally 1 is active 0 volts DC is present on its
output and 12 volts DC is present on Tally Output
2. This choice is provided so that the function sup-
ported by the two tally outputs that are functioning
differentially, typically a bi-directional LED array, can
be operated in a reverse manner. (This configuration
setting can eliminate the need for re-wiring connec
-
tions should the LED array’s colors need to operate
in an opposite manner.)
Note that when either Differential – Active High or Dif
-
ferential – Active Low has been selected the configu-
ration source for Output 2 is no longer available. The
function will be “grayed out” to indicate that only the
source for output 1 is active. (It will control the output
states of both Tally Output 1 and Tally Output 2.)
Tally Outputs – On/Off Buttons
On the Tally Outputs page there is a section called
On/Off Buttons which provides two software-imple-
mented (virtual) pushbutton switches. These allow
manual control of the status of the two tally outputs
when their respective output source configuration
has been selected for STcontroller On/Off Button. If
this configuration choice has not been selected then
the button will be “grayed out” and not available for
use.
On/Off Button – Output 1: This can be pressed,
using a mouse or keyboard key, to change the sta
-
tus of Tally Output 1 from off-to-on or on-to-off. This
can prove useful during installation and testing of
the Model 209’s tally outputs. It can also be used to
manually control the status of Tally Output 1.
On/Off Button – Output 2: This can be pressed, us
-
ing a mouse or keyboard key, to change the status of
Tally Output 2 from off-to-on or on-to-off. It can find
value during installation and testing of the Model
209’s tally outputs. It can also be used to manually
control the status of Tally Output 2. Note that this
button will be “grayed out” if either of the differential
operating modes has been selected. (The action of
Tally Output 2 will, in this situation, depend on the
action of Tally Output 1.)
path that is active only when TOX is selected. This
helps to prevent high-frequency signals from reach
-
ing a user’s ears. However, using 20 kHz, or even
22 kHz, as the trigger will help minimize the chance
that a user’s ears will be impacted.
TOX – Headphone Ch2: This function has the same
action as TOX – Headphone Ch1 but utilizes the
Dante receiver (input) channel Headphone Ch2. This
is provided for control flexibility.
Configuration – Output 2 Source: The six configu
-
ration choices that are available for controlling Tally
Output 2 are the same as provided for Tally Output 1.
Please refer to the previous paragraphs for details.
Note that this configuration section will be “grayed
out” if the configuration for the Operating Mode has
been selected for Differential – Active High or Differ
-
ential – Active Low. This is because selecting one of
the two differential modes will disable Tally Output 2
as a separate function and associate its output state
with Tally Output 1.
Configuration – Operating Mode
Choices are Independent, Differential – Active High,
and Differential – Active Low.
This configuration choice determines how the Model
209’s two tally outputs function. When Independent
is selected Tally Output 1 and Tally Output 2 are,
as expected, completely independent. They are
controlled by their selected configuration source,
providing 0 volts DC when inactive and 12 volts DC
when active.
Differential – Active High: When selected Tally
Output 1 and Tally Output 2 work together, creating
a differential action. (Differential relating to the word
difference and the two tally outputs always providing
states opposite of each other.) When Tally 1 is not
active 0 volts DC is present on Tally Output 1; 12
volts DC is present on Tally Output 2. When Tally 1
is active 12 volts DC is present on its output and 0
volts DC is present on Tally Output 2.
Differential – Active Low: When selected Tally
Output 1 and Tally Output 2 again work together but
in a manner opposite of Differential – Active High.
When Tally 1 is not active 12 volts DC is present on
