IN1502 1 Chapter One Introduction About this Manual About the IN1502 Features and Options
Introduction About this Manual This manual describes how to install, configure, and operate the Extron IN1502 video scaler and how to operate the optional IR 901 infrared remote control (part #70-152-01). Throughout this manual the terms “IN1502”, “video scaler”, and “scaler” are used interchangeably to refer to the same product.
3:2 pulldown detection for NTSC and 2:2 film detection for PAL video sources — These advanced film mode processing features help maximize image detail and sharpness for video sources that originated from film. When film is converted to NTSC video, the film frame rate has to be matched to the video frame rate in a process called 3:2 pulldown. Jaggies and other image artifacts can result if conventional deinterlacing techniques are used on film-source video.

Installation and Operation Mounting the Scaler UL rack mounting requirements The following Underwriters Laboratories (UL) requirements pertain to the safe installation of the IN1502 in a rack. 1. Elevated operating ambient temperature — If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient temperature.
1U Universal Rack Shelf 1/2 Rack Width Front False Faceplate Front false faceplate uses 2 screws. (2) 4-40 x 3/16" Screws NOTE: Using screws longer than 3/16” will damage the unit and void the warranty. Use 2 mounting holes on opposite corners. Rack mounting the IN1502 4. Attach the false front panel (provided with rack shelf part #60-190-01) to the unoccupied side of the rack (as shown above), or install a second halfrack-width device in that side by repeating steps 1 through 3. 5.

Menus, Configuration, and Adjustments Scaler configuration and adjustments can be performed by using the front panel controls and the menus that are displayed on the IN1502’s LCD screen. These menus are used primarily when the scaler is first set up. Moving through menus by using front panel controls Menu button — Press the Menu button to activate menus and to scroll to the four main menus. Next button — Press the Next button to move between the submenus of a selected main menu.

Installation and Operation, cont’d 2:2 Pulldown detection (PAL film mode detect) submenu For the currently selected input, set this feature to “On” if the source is PAL video that originated in film. For standard PAL video sources, such as cameras, set this feature to “Off” (default). This feature does not apply to NTSC video sources since film mode (3:2 pulldown) is automatically detected for those signals.
Input Reset To reset each input of the IN1502 scaler to its default centering and sizing values, hold down the specific input button until the Input # Reset message is displayed on the LCD screen. Autoswitch must be set to “OFF” before Input Reset can activated. See “Autoswitch (Autosw) mode” in the “Advanced Configuration” section of this chapter. System Reset To reset the IN1502 to all of its default values, hold down the Input 1 button while simultaneously plugging in the power cord.
Installation and Operation, cont’d IR 901 Infrared Remote Control The IR 901, shown at right, replicates all of the front panel controls except the Menu and Next buttons. If Executive mode has been enabled on the IN1502, input selection and adjustments can still be made from the IR 901. You must use the IN1502’s front panel, a host computer, or an RS-232 control device to configure and program the scaler. See chapter 3, “Serial Communication”, for details.
Troubleshooting This section gives recommendations on what to do if you have problems operating the IN1502, and it provides examples and descriptions for some image problems you might encounter. The following are some tips to help you in troubleshooting. 1. Some symptoms may resemble others, so you may want to look through all of the examples before attempting to solve the problem. 2. Be prepared to backtrack in case the action taken doesn’t solve the problem. 3.

Serial Communication The IN1502 can be remotely controlled via a host computer or other device (such as a control system) attached to the rear panel Remote connector. The control device (host) uses Extron’s Simple Instruction Set (SIS) commands. The scaler uses a protocol of 9600 baud, 1 stop bit, no parity, and no flow control.
Using the command/response tables The command/response tables on the next page list valid command ASCII codes, the scaler’s responses to the host, and a description of the command’s function or the results of executing the command. Uppercase and lowercase characters may be used interchangeably in the command field.

Firmware Upgrade Installation In some cases, the IN1502’s firmware may require replacement with an updated version. There are three user-replaceable firmware chips: U41 — the main microcontroller, U38, and U17. The numbers are printed on the circuit board. We recommend that you send the unit to Extron for service and updates. Changes to firmware must be performed by authorized service personnel only. Some IN1502 firmware updates must be performed at the Extron factory.
Appendix, cont’d U17 U38 U41 5. After you are electrically grounded, you can remove the U17 IC chip or U38 IC chip by grasping it firmly with your fingers and pulling it out; then continue to step 8. Removal of the U41 IC chip requires a PLCC IC puller tool. To remove the U41 chip, align the hooks of a PLCC IC puller tool with the slots located in opposite ends of the U41 firmware chip. 6. Insert the hooks into the slots, and squeeze the tool gently to grasp the chip. 7.
