PS/2 VIDEO CAPTURE ADAPTER/A The purpose of this file is to present information that would update the user documentation that came with your adapter. The PS/2 Video Capture Adapter/A is available in two versions. One for use with NTSC-composite signals (VCA/A) and one for use with PAL-composite signals (VCA/A PAL). Update Number 1: If you are using OS/2 and you have selected the interrupt level for the PS/2 Video Capture Adapter/A to be shared with a system interrupt such as level 7, you will get an advisory message from the operating system when you run the diagnostic program IDDA.EXE. This error message will inform you that an interrupt vector has been changed. You will have two options. These options are either to end the program or to ignore the error and continue. If you select the option to ignore the error and continue, the diagnostic program will operate properly and the interrupt vector will be properly restored when the diagnostic program is completed. Update Number 2: Reference page number 1-17: The description for the "Save from live source" and "Save from Memory" state that the extension for the saved file will be either 565 or 664 depending on the current pixel format selected. This version of the diagnostics will only save the images in 664 pixel format and the extension will be 664 on the disk. Update Number 3: Error # 40: In case of an error message with an error code # 40, either during the Composite Video Wrap Test or the Y/C Wrap Test, let the card warm up for about five minutes after the PS/2 system has been turned on. Run the test once again. The following is a very brief overview of the installation of the card and the contents of your adapter package. Please refer to the user documentation in the adapter package for the more detailed information on these subjects. The following items should be inside the box containing this diskette: 1. The adapter card. 2. A Primary I/O Cable which has ten separate cables which end in RCA sockets, with a 20-pin connector on the other end. (For the VCA/A PAL adapter this is a Primary I/O cable with twelve separate cables which end in RCA sockets, with a 37-pin connector on the other end.) 3. A S-Video Output Cable which is also used by the diagnostic program for a Y/C Wrap Cable. This cable has an S-Connector at one end and two RCA plugs at the other end. The BLACK RCA plug is the LUMA (Y) cable and the RED is the CHROMA (C) cable. (This cable is not included with the VCA/A PAL adapter. The VCA/A PAL adapter has two extra cables on the Primary I/O cable which serve as LUMA and CHROMA output connections.) 4. Three 75 Ohm Terminators. 5. A short cable with RCA plugs at both ends which is used by the diagnostic program in Wrap Tests for RGB and Composite Video. (There are two of these cables supplied with the VCA/A PAL adapter.) 6. The diskette which has this README.DOC file, the diagnostic program and related modules, and two Adapter Definition Files (ADF). @704E.ADF is used during the CONFIGURATION step in the installation of the VCA/A adapter (NTSC composite). @70CE.ADF is used during the CONFIGURATION step in the installation of the VCA/A PAL adapter (PAL composite). 7. Video Capture Adapter - Installation and Technical Reference Manual Please be sure that all of these things are in the box. INSTALLATION First insert your Backup Reference Diskette into drive A and either do an Ctrl-Alt-Del or Power On your system to load the configuration support program from the reference diskette. Use the Copy Options File to copy the adapter's ADF onto your backup reference diskette. (The Device ID for the VCA/A is @704E and for VCA/A PAL it is @70CE.) Before proceeding with the installation either have your copy of the user documentation open to the installation section or have a printed copy of this README.DOC file available. Power off your system to continue with the installation. Refer to the operation instructions for your IBM PS/2 system and remove the covers so that you can install the adapter into your system. After the adapter has been installed into the card slot of your choice, insert your Back Up Reference Diskette in drive A and power on the system. You will be notified that the system configuration has changed. Proceed with the Automatic Configuration. When the Automatic Configuration is completed, select the Set Configuration Option and review the current configuration of your system. If you wish to select configuration options other than the default options selected for the adapter by the Automatic Configuration, proceed according to the instructions in your Operations Guide for the Reference Diskette. Complete the configuration operation and restart your system from the hard file or diskette. ATTACHING INPUT AND OUTPUT DEVICES TO THE ADAPTER For the VCA/A adapter (NTSC composite): The Primary I/O Cable will have the ends labeled with numbers 1 thru 10. 1 = Output Composite Sync Signal 2 = Blue Color Signal for RGB Output 3 = Green Color Signal for RGB Output 4 = Red Color Signal for RGB Output 5 = Composite Video (NTSC) Output Signal 6 = Input Composite Sync Signal 7 = Blue Color Signal for RGB Input 8 = Green Color for RGB or Luma (Y) for Y/C Input 9 = Red Color for RGB or Chroma (C) for Y/C Input 10 = Composite Video (NTSC) Input Signal If you do not have an RGB monitor, which has 75 ohm termination, be sure to place the RCA Termination plugs which came with the adapter on lines 2, 3, and 4. If the RGB output lines are not terminated, the Y/C and the Composite Video outputs will distort the brightness of the image. For the VCA/A PAL adapter (PAL composite): The Primary I/O Cable will have the ends labeled with identifiers OS, OB, OG, OR, OV, IS, IB, IG, IR, IV, OC, and OY. OS = Output Composite Sync Signal OB = Blue Color Signal for RGB Output OG = Green Color Signal for RGB Output OR = Red Color Signal for RGB Output OV = Composite Video (PAL) Output Signal IS = Input Composite Sync Signal IB = Blue Color Signal for RGB Input IG = Green Color for RGB or Luma (Y) for Y/C Input IR = Red Color for RGB or Chroma (C) for Y/C Input IV = Composite Video (PAL) Input Signal OC = Chroma (C) Signal for Y/C Output OY = Luma (L) Signal for Y/C Output If you do not have an RGB monitor, which has 75 ohm termination, be sure to place the RCA Termination plugs which came with the adapter on lines OR, OG, and OB. If the RGB output lines are not terminated, the Y/C and the Composite Video outputs will distort the brightness of the image. DIAGNOSTIC PROGRAM OPERATION The adapter diagnostic program on this diskette will operate under DOS 3.4 or higher or in the DOS Compatibility Box for OS/2. The diagnostic program is designed only to test the functions of the adapter and to allow you to experiment with the adapter. It is not designed to support application interfaces. It is suggested that you make a directory on your hard file and copy the IDDA diagnostic modules into that directory. Below is a an example for doing this. At the main prompt for the DOS or the OS/2 DOS Compatibility Box, type MD \IDDA. COPY A:IDDA*.* C:\IDDA Assuming you have changed the default drive and directory to that containing IDDA.EXE, type IDDA at the System Prompt. The Main Option Selection Menu should then appear on your system display. Your choices at this time are the BASE TEST, WRAP TESTS, FUNCTION TESTS, FILE OPERATIONS, and PATTERNS. For all menus including the Main Option Selection Menu, there are HELP panels you may review by pressing the F1 key. The diagnostic menus use the CUA interface rules. You may use the directional cursor keys to vary your selection of options. The ENTER key will invoke your selection. The diagnostic tests themselves are divided into three categories. These are BASE TESTS which performs static tests on the adapter's registers and memories; WRAP TESTS which check the display and digitize operations without the need for external devices; and the FUNCTION TESTS which allows you to manipulate the adapter function with your input and output devices attached to the adapter. For each group of tests you can run the tests once, run the tests continuously until an error is detected, or run the tests continuously and log every error to a file named IDDA.LOG. In the Function Tests, the Color Control values are loaded from the factory settings recorded on the adapter whenever you select a different input source. To manually change the Color Control values, position the cursor under the value to be changed and press ENTER. Clear the current value using the BACKSPACE. Enter the new value and press ENTER when completed. FILE OPTIONS The File Options performs file operations such as saving an image from a live source to a file, or save the contents of the video board memory to a file, or load a picture file which was previously saved. PATTERNS The Pattern function in the diagnostic program allows you to clear the Video Memory on the adapter to all White or all Black. You can also generate a standard Full Field Color Bar pattern. This pattern has eight evenly spaced bars. Going from left to right these bars are white, yellow, cyan, green, magenta, red, blue, and black. The bars on the left and right end of the pattern will not appear the same width as the other bars on overscan monitors. The Color Bars will help you to adjust your monitor to the proper colors. The Vertical Bars available in the pattern option, will let you see if the monitor is properly holding the image sync and if the monitor is properly aligned. (With VCA/A PAL cards you will notice a (black) border around the selected patterns.)
