Picture Adjustments The picture adjustments allow you to fine tune the image quality of the selected input. When you press one of the Picture Adjustments buttons (Color/Tint, Brightness/Contrast, Size, Center, or Filter) once, the corresponding image adjustment menu for the selected output (lit Output LED) image appears on the LCD screen. Select the other output using the Output buttons to call the image adjustment menu for the other output.
3. Rotate the Adjust knob or Adjust knob to vary the settings within the following adjustment ranges: NOTE: The Adjust knobs have no mechanical limits to their rotation. • Color/Tint: Color adjusts within a range of 0 to 127. Tint adjusts within a range of 0 to 255. • Brightness/Contrast: The range for both adjustments is 0 to 63. • Size: Observe the display and turn the Adjust knob to increase or decrease the horizontal size of the image.
IP Information To set up the ISM for operation via its Ethernet port, you need to know and be able to change the IP address. One way to do this is via the IP address and hardware address screen. To access the IP address and hardware address screen, press and hold the Color/Tint and Detail buttons while you apply power to the ISM (see figure 25). When the ISM is finished initializing, it displays both addresses. Press and hold both buttons simultaneously while applying power.
Optimizing the Video Perform the following steps, in sequence, after you have installed the ISM. This procedure will help you to configure the switcher for the best settings for your display environment. In a multi-screen environment, perform this procedure for each display. See Advanced Configuration menu on page 20, to select and output a test pattern and to select and output blue-only video. See Picture Adjustments on page 25, to make adjustments to the picture quality.
Setting up a DVD source To get the best results when using a DVD as a video source, Extron recommends that the DVD player itself be set up to output an aspect ratio of 16:9 and not 4:3. Because all DVDs are mastered as 16:9, having them set up for anything else causes the player to internally scale and compress the signal. The DVD player’s scaling and compression defeats the advantage of having 3-2 pulldown detection in the ISM.
General Checks 1. Ensure that all devices are plugged in and powered on. The switcher is receiving power if the LCD is displaying the default display cycle. 2. Ensure an active input is selected on the switcher. 3. Ensure that the proper signal format is supplied. 4. Check the cabling and make corrections as necessary. 5. Call the Extron S3 Sales & Technical Support Hotline if necessary. Specific Problems The table below shows some common operating problems and their solutions.
Programming Guide This section describes: • RS-232 Link • Ethernet Link • Symbols • Switcher-Initiated Messages • Host-to-Switcher Instructions • Switcher Error Responses • Using the Command and Response Table RS-232 Link The switcher’s rear panel Remote port 9-pin D female connector (see figure 26) can be connected to the RS-232 serial port output of a host device, such as a computer running the HyperTerminal utility or a control system.
Ethernet Link The rear panel Ethernet connector on the switcher can be connected to the an Ethernet LAN or WAN (see figure 27). This connection makes SIS control of the switcher possible using a computer connected to the same LAN or WAN.
Symbols Symbols (X` values), defined below, are used throughout the discussions of the switcherinitiated messages that begins on the next page and the command/response table that begins on page 37. The symbols represent variables in the switcher-initiated messages and the command/response table fields.
Switcher-Initiated Messages When a local event such as power-up or a front panel operation occurs, the switcher responds by sending a message to the host. The switcher-initiated messages are listed in the following pages. The messages are underlined. The switcher does not expect a response from the host; but, for example, the host program might request a new status.

Ethernet Connection This section describes: • Cabling • Determining Default Addresses • Connecting as a Telnet Client The rear panel Ethernet connector (see figure 53) on the ISM switcher can be connected to an Ethernet LAN or WAN. This connection makes SIS control of the switcher possible using a computer connected to the same LAN.
Determining Default Addresses To access the ISM switcher via the Ethernet port, you need the Extron ISM IP address. If the address has been changed to an address comprised of words and characters, the actual numeric IP address can be determined using the Ping utility. If the address has not been changed, the factory-specified default is 192.168.254.254. Ping can also be used to test the Ethernet link to the ISM.
Connecting as a Telnet Client The Microsoft Telnet utility is available from the DOS prompt. Telnet allows you to input SIS commands to the ISM from the PC via Ethernet. Access the DOS prompt and start Telnet as follows: 1. Click Start > Run. 2. At the Open prompt, type command. 3. Click the OK button. 4. At the DOS prompt, type telnet and press to figure 55. Enter . The computer returns a display similar Microsoft (R) windows 2000 (TM) Version 5.
Escape character and Esc key When Telnet is first started, the utility advises that the Escape character is ‘Ctrl+]’. Many SIS commands include the keyboard Esc key. Consequently, some confusion may exist between the Escape character and the Escape key. The Telnet Escape character is a key combination, the Ctrl key and the ] key pressed simultaneously, that returns you to the Telnet prompt while leaving the connection to the ISM intact. The Escape key is the Esc key on the computer keyboard.
