N The output buttons and the Enter button flashes three times only and then
extinguishes. The Enter button must be pressed before it becomes unlit. If it
extinguishes before being pressed, repeat steps 3 and 4.
7 . Press View and observe the LCD display (see figure 3-18).

8 . Press Esc to clear View and reset the LCD.
9 . Press any unlit I/O button to set it back to the default state.
N Alternatively, to replace an existing audio input tie with a different
audio input tie, follow all the steps below, deselecting (press) the video button
instead of the audio button at step 3. Input and output buttons light red.
To replace both video and audio ties, ensure both I/O buttons are lit at
step 3. The inputs and outputs light amber.
I/O (Input/Output) grouping
The ISM 824 has I/O grouping, that allows the user via front panel control to setup
four separate, non-interactive groups of inputs and outputs. The four groups are
assigned by the control buttons as follows;
Enter = group #1, Preset = group #2, View = group #3, and Esc = group #4
N For I/O grouping to function at least two groups must be created.
When setting up the groups from the ISM 824 front panel, any input or output can
be assigned to any of the four groups, or to no group, but not to multiple groups.
Only those inputs and outputs that are within the same group can be tied with one
another. For example, inputs and outputs within group 4, cannot be tied to inputs
or outputs belonging to groups 1, 2, or 3. Ungrouped inputs and outputs can be
added to any group, or tied to one another independently of any group via front
panel control.
N Inputs and outputs within different groups can only be tied to one another
across the groups by using SIS commands or via the Ethernet. They cannot be
tied by front panel operation or by ISM 824 Control software.
Grouping allows specific video formats to be sent to output devices that support
that format without fear of sending them to incompatible output devices.
Grouping can also be used for input and output devices that are physically in
separate rooms, or for isolating video from being displayed on specific outputs for
security reasons.
Existing groups are displayed on the LCD when grouping is being setup or
changed. In addition, any selected input or output button, when pressed and held
for three seconds, lights green if they are already assigned to a group (including
group 0 = no group). At the same time the other buttons allocated to the same
group also light green while the selected button is held down. This allows the user
to tie those buttons within the same group.
N The device times out and all lit buttons extinguish, if the selected button is held
for more than 30 seconds.
