ISM 824 Integration Scaling Multiswitcher • Operation and Setup 3-6
Front Panel Operation
To enable any selected input signal to be viewed on a display device, the input
must be tied to an output. Any input can be tied to any output.
N
Ties can be made by front panel operation, RS-232, or through Telnet/HTTP or
with the ISM 824 Windows Control Program.
See chapter 4, “SIS ™ Programming and Control”, for RS-232/RS-422 methods ,
chapter 5, “ISM 824 Multiswitcher Software” for WCP methods , and chapter 6 ,
“HTML Operation” for HTTP methods.
Making input to output ties
To tie an input to any untied outputs do the following:
1 . Press the Esc button, to clear any input, output, or control button changes that
may be pending.
2 . If not already lit, select the Video button (lights green), Audio button (lights
red ), or both for the desired tie configuration.
3 . Press (select) the desired input. Any existing ties light up (steady), as shown
in the table below.
4 . Press any untied (unlit) output(s). The output button flashes the appropriate
color (green, red, or amber) to indicate a tentative tie, and the Enter button
flashes green.

5 . Press the Enter button to make the tie. The input, output, and Enter buttons
extinguish.
N The output buttons and the Enter button flashes for 30 seconds and then
extinguishes. The Enter button must be pressed before it becomes unlit. If it
extinguishes before being pressed, repeat steps 3 and 4.
Only one video input and one audio input can be tied to an output.
If an input with no existing tie is selected, only that input’s button lights when
pressed. No output buttons light.
As each input and output is selected, the associated output button flashes the
appropriate color to indicate a tentative tie. Buttons for output(s) that were
already tied to the input light the appropriate color (steady). Outputs that are
already tied should be left on if that tie is desired, along with any new (flashing)
selections.
If a tie is made between an input and an output, and the selected output
was previously tied to another input, the older tie is broken in favor of the
newer tie when the Enter button is pressed.
If any associated lit output button (an existing tie) is toggled off by pressing
the button and the Enter is pressed, the existing tie to that output is lost.
Any video only tied output can have an audio tie added, any audio only tied
output can have a video tie added, and any output with both video and audio
ties can have either the video or audio tie removed.
