ISM 482 Integrated Scaling Matrix Switcher • HTML Operation 56

Freezing the Output

You can freeze either output by clicking the Output 1 or Output 2 Freeze button. The

Freeze button turns blue. When the output is frozen, the input source can be removed and

the ISM functions as a video store.

Click the Freeze button again to toggle freeze mode off.

Outputting a Test Pattern

You can select a test pattern to output on the output 1 and/or output 2 monitors. The test

patterns are helpful when adjusting the connected displays for color, convergence, focus,

resolution, contrast, grayscale, and aspect ratio.

Output a test pattern as follows:

1. Click in the Test Pattern field. A drop down-box appears (see figure 40).

2. Click the desired test pattern.

3. Click the Output 1 and/or Output 2 check box to turn on the test pattern.

Previewing the Scan Rate

You can read the horizontal and vertical scan rates of output 1 and

output 2 by clicking the Output 1 or Output 2 View Input Scan

Rate button. The horizontal and vertical frequencies are displayed

in the Horizontal and Vertical windows on the page.

Using Blue-Only Mode

You can toggle Blue-Only mode on and off for either output by clicking the

Blue Screen Mode Output 1, Output 2, or both check boxes. Blue-Only mode is

helpful in the setup of the color and tint of the incoming video signal. In the Blue-Only

mode, only the sync and blue video signals are passed to the display.

Executive Mode

You can toggle Executive mode on and off by clicking the Executive Mode On or Off check

box. The Executive mode limits the operation of the Integration Scaling Matrix Switcher

from the front panel. When the switcher is in Executive mode, all of the front panel functions

are disabled except for input selection.
