IN1508 • Setup Guide
Set up the display
N You may need to first set the display's aspect ratio to 1:1, pixel for pixel, or "true" mode to eliminate overscan.
Test patterns are available on IN1508 units that shipped after March 2007 and are firmware version 2.30 or higher. Earlier
units may show the test pattern submenu, but it is not selectable.
1. Navigate to Advanced > Test Pattern to access the Test Pattern selection box.
2. Press and to select the Alt. Pixels test pattern. Press Enter. Adjust the display's clocking and phase as follows:
a. Use the display's clocking or coarse sync controls to eliminate vertical banding or "jail bars".
b. Use the display's phase or fine sync controls to eliminate horizontal noise.
3. Navigate again to Advanced > Test Pattern to access the Test Pattern selection box.
4. Press and to select the switcher's Crop test pattern. Adjust the display's horizontal and vertical shift controls until
all four crop lines are visible.
5. Disable the crop pattern. No further adjustments or Auto-Image should be performed at the display.
Input 5 setup
Input 5 can accept interlaced, progressive, or HDTV component video. You need to configure the switcher to properly
process input 5 as follows:
1. Navigate to Input > Input 5 to select Input 5 selection box.
2. Press and to select the correct setting for the video source connected to input 5. Press Enter.
• Interlaced — NTSC (480i) and PAL (576i)
• Progressive — 480p and 576p
• HDTV — 720p, 1080i, and 1080p
Aspect ratio setup
Each input has a unique aspect ratio setting, either 4:3 (default) or 16:9. The aspect ratio is applied to all video signals that are
applied to that input. If necessary, change the aspect ratio for an input as follows:
1. If necessary, press the Input button to select the input to be set.
2. Navigate to Input > Aspect Ratio to access the Aspect selection box.
3. Press and to select the desired aspect ratio. Press Enter.
4. Repeat steps 1 through 3 as necessary for the remaining inputs.
Input 8 EDID emulation
If the desired output resolution is not available from the DVI video source connected to input 8, you can use the switcher's
SIS commands to set the EDID emulation for input 8. Connect a PC to the switcher's RS-232 port (l) and issue the following
command:
nn*y*41#
where:
nn = Switcher resolution (EDID): y = Video refresh rate:
00 = Match output resolution (default) 0 = Match output rate (default)
01 = 640 x 480 (VGA) 12 = 576p 1 = 50 Hz 3 = 75 Hz (24 Hz for 1080p)
02 = 800 x 600 (SVGA) 13 = 720p 2 = 60 Hz 4 = 59.94 Hz
03 = 1024 x 768 (XGA) 14 = 1080i
04 = 1280 x 1024 (SXGA) 15 = 1080p
05 = 1024 x 852 16 = 1280 x 768
06 = 1024 x 1024 17 = 1440 x 900
07 = 1366 x 768 18 = 1680 x 1050
08 = 1365 x 1024 19 = 1280 x 800
09 = 1400 x 1050 20 = 852 x 480
10 = 1600 x 1200 (UXGA) 21 = 1080p Sharp
11 = 480p 22 = 1920 x 1200
The switcher responds with "DDCnn*y]", where ] is carriage return and line feed characters.
N For more information and a complete list of SIS commands, refer to the IN1508 User's Manual, at www.extron.com.

Inputs 6 and 7 setup
RGB inputs 6 and 7 may need minor horizontal and vertical start, active pixels (horizontal), active lines (vertical), total pixels,
and phase adjustments for best image quality.
1. Press the Input button to select the input to be optimized.
2. Execute the Auto-Image™ function by pressing and holding the Input 6 or Input 7 button for approximately 4 seconds.
Release the button. Evaluate the resulting image. If it is satisfactory, this portion of the setup is complete. If the image
is not satisfactory, additional adjustment is necessary; perform steps 3 through 5.
3. Navigate to Input > Advanced to access the Advanced submenu selection boxes.
4. For soft text , vertical banding, or both, adjust the Total Pixels.
For fine horizontal noise, adjust the Phase.
For centering, adjust the Horizontal Start and Vertical Start.
For sizing, adjust the Horizontal Active and Vertical Active.
5. Press and to adjust the highlighted setting.
Operations (PIP mode)
Each of the eight inputs is assigned to one of two operational groups:
• Low resolution — Inputs 1 through 4 (and input 5 if it is configured as
interlaced in the menu system)
• High resolution — Inputs 6 through 8 (and input 5 if it is configured as
progressive or HDTV in the menu system)
Input selection operation
Input selection acts differently, depending on whether PIP mode is on or off:
• PIP mode off — If the PIP mode is off (the PIP On LED is off), the input button selects a new input for the main window.
• PIP mode on — Pushing the input button selects a new input for either the main window or the PIP window, depending
on the group (high resolution or low resolution) the input is in. The selected input replaces the previously selected input
from the same group in whichever window
the replaced input had been displayed.
° In the figure at right, input 3 replaces
input 1 in the PIP window (a).
° In the figure at right, input 8 replaces
input 6 in the main window (b).
Picture-in-picture mode operation
The two images displayed when the PIP feature is on (the PIP On LED is lit) must come from different input groups (one high
resolution and one low resolution) and you cannot toggle (swap) between two inputs in the same group.
• If the primary input (the main window) is high-resolution, the secondary input (the PIP window) must be low-resolution.
• If the primary input is low-resolution, the secondary input must be high-resolution.
Picture-in-picture swap
The PIP swap function swaps the main and PIP inputs. In the figure above right, when you push the Swap button:
• Input 3 replaces input 8 in the main window (c).
• Input 8 replaces input 3 in the PIP window (c).
If PIP mode is off (the PIP Mode On LED is off), the PIP swap function
toggles between the most recently selected low-resolution and high-
resolution inputs. Unlike when PIP mode is on, however, the input
remains full screen.
PIP Mode
Navigate to Advanced > PIP Mode and press and buttons to select among the
image size and position modes shown at right.
N If either side-by-side option is selected, the PIP size adjustment does not work.
