NThe 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).

Output 1 still tied to input 2 as audio, but now to input 7 as video

Outputs 2 and 7 still tied to input 3 as audio only

Outputs 3 and 4 still tied to input 2 as video and to input 8 as audio

Output 6 is still tied to input 3 as video and audio

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.

NAlternatively, 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

NFor 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.

NInputs 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 device. 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.

NThe device times out and all lit buttons extinguish, if the selected button is held for more than 30 seconds.
