************************************************************************* * * * LLMVAS.EXP * * * * August 18, 1993 * * * * Lyon Lamb Video Animation Systems * * Video Tape Recorder * * Autodesk Device Interface * * * ************************************************************************* This documentation will help you install the Lyon Lamb MiniVAS and PCVAS ADI (LLMVAS.EXP) for Autodesk 3D Studio. The following assumes that 3D Studio has been installed in the directory C:\3DS. If this is different on your system, please substitute the appropriate directory when reading these instructions. 1) First preblack your video tape to automatically record control track, frame code, and time code on it. 2) Copy LLMVAS.EXP into the 3D Studio drivers sub-directory. This will most likely be the sub-directory C:\3DS\DRIVERS. 3) Edit the file 3DS.SET in the C:\3DS directory to change the VTR-DEVICE from the default [DIAQUEST] to VTPADI. The proper syntax is: VTR-DEVICE = VTPADI 4) In 3DS.SET, examine the "Rendering Display" section. Modify the default rendering driver according to Autodesk's built-in output drivers. Change the rendering display parameters to match the video output card in your system. A few compatible video graphic cards are VISTA, TARGA or VISION16. The proper syntax for a VISTA (756x486) is: RENDER-DISPLAY = VISTAH NOTE: You must have SET RDPADI or SET RCPADI statement in your AUTOEXEC.BAT for these to function. Consult your 3D Studio manual. Alternatively, you can use the "3DS VIBCFG" command to change your rendering display to match the video output card in your system. Consult your 3D Studio Rel. 3 Installation Guide for details. 5) Add the following line to the end of your AUTOEXEC.BAT file: SET VTPADI=C:\3DS\DRIVERS\LLMVAS.EXP The line tells 3D Studio that the ADI video tape recorder driver you want to use is LLMVAS.EXP. 6) Now you need to add another line to your AUTOEXEC.BAT file. The line tells the ADI driver how your system is set up. The format of this line depends on whether you have a MiniVAS or a PCVAS and how it is set up. The format of the line is: SET LLMVAS={F,T,L} {N,P} {C1,C2,C3,C4} I# Vaa R# Immediately following the description of the parameters are several examples of specific configurations and the proper SET LLMVAS= line to place in your AUTOEXEC.BAT file. Description of the parameters: ----------------------------- {C1,C2,C3,C4} C1 - Use COM port 1 C2 - Use COM port 2 C3 - Use COM port 3 C4 - Use COM port 4 I# Specify the IRQ number to use for communication with the VAS e.g. I10 means use IRQ 10 I5 means use IRQ 5 NOTE: MiniVAS users do not normally need to specify the I parameter. {F,T,L} F - Use frame code T - Use serial time code L - Use longitudinal time code (available only for PCVAS) {N,P} N - Use NTSC timing (30 frames per second) P - Use PAL timing (25 frames per second) Vaa Specify the VTR identification code (consult your MiniVAS or PCVAS manual) e.g. VSM is the Sony VO-9850 VP7 is the Panasonic AG-7750 R# Specify the preroll time (1 to 20 seconds) for recording e.g. R6 set a preroll time of 6 seconds R11 set a preroll time of 11 seconds NOTE: Specifying R0 will use the default preroll time stored in the MiniVAS's or PCVAS's memory. Example SET LLMVAS= configurations: ---------------------------------- Example A: A MiniVAS connected to COM1 (C1), using frame code (F), NTSC timing (N), the Sony VO-9850 (VSM), and a recording preroll time of 8 seconds (R8): SET LLMVAS=C1 F N VSM R8 Example B: A MiniVAS connected to COM2 (C2), using time code (T), PAL timing (P), the Sony VO-9850 with time code option (VSN), and a recording preroll time of 10 seconds (R10): SET LLMVAS=C2 T P VSN R10 Example C: A MiniVAS connected to COM3 (C3), using frame code (F), NTSC timing (N), the Sony BVU-2500 (VSD), and the default recording preroll time (R0): SET LLMVAS=C3 F N VSD R0 Example D: A PCVAS connected to COM3 (C3), IRQ number 10 (I10), using frame code (F), NTSC timing (N), the Sony VO-9850 (VSM), and a recording preroll time of 6 seconds (R6): SET LLMVAS=C3 I10 F N VSM R6 Example E: A PCVAS connected to COM1 (C1), IRQ number 4 (I4), using frame code (F), PAL timing (P), the Hitachi HR-230 (VH3), and the default recording preroll time (R0): SET LLMVAS=C1 I4 F P VH3 R0 Example F: A PCVAS connected to COM4 (C4), IRQ number 5 (I5), using longitudinal time code (L), NTSC timing (N), the Panasonic AG-7750 (P7), and a recording preroll time of 7 seconds (R7): SET LLMVAS=C4 I5 L N P7 R7 7) After you add the proper SET LLMVAS= line to your AUTOEXEC.BAT file and save it, reboot your computer to put the changes into effect. 8) Open 3D Studio, go to Keyframer (F4), and select the following from the menu on the left: Renderer ... VTR Control ... VTR Setup ... Hit the Initialize button, wait, then a dialogue box appears reading: VTR is On-line. 9) Please refer back to the Studio 3D documentation for a detailed explanation regarding the: VTR Control... and VTR Setup... menus. ================================================================ Detailed Description of the LLMVAS Environment Variable Settings ================================================================ The following is a full description of the LLMVAS environment variable settings. Syntax: ------ SET LLMVAS={C1|C2|C3|C4} {I#} {Axxx} {N|P} {F|T|L} {Vaa} {Rdd} Default Setting: --------------- If the LLMVAS environment variable is not defined, the driver assumes the following default setting: SET LLMVAS=C3 I10 A3E8 N F R0 This specifies COM port 3, IRQ 10, I/O base address 0x3e8, NTSC timing, frame code operation, and the default preroll time of the VAS. Notes on the Syntax: ------------------- - The curly brackets "{" and "}" show groups of related options. - Vertical bars "|" separate each available option in a group. - Capital letters or lower case letters may be used. - Unrecognized options will be ignored (e.g. the letter "Z"). - Spaces may optionally separate each option. - Spaces may not separate the letters composing an option. (e.g. "VSM" works, but "V SM" does not) - Options can be given in any order but subsequent options from the same group override previous options from the same group. (e.g. "NP" means PAL operation since the P comes after the N) Parameters: ---------- COMMUNICATIONS PORT: {C1 | C2 | C3 | C4} C1 - COM1, IRQ4, 0x3F8 C2 - COM2, IRQ3, 0x2F8 C3 - COM3, IRQ10, 0x3E8 C4 - COM4, IRQ11, 0x2E8 This option selects the serial port to which the MiniVAS or PCVAS is connected. The assumed IRQ and I/O base address for the COM port are listed above. However, specifying a different IRQ using the I option (described below) overrides the assumed IRQ, and specifying a different I/O base address using the A option (also described below) overrides the assumed I/O base address. Default: If this option is not specified, then the driver assumes COM3 (C3). IRQ NUMBER: {I#} This option selects the IRQ number to use for communication with the PCVAS or MiniVAS. The PCVAS has a set of selectable jumpers labelled (IRQ2, IRQ3, IRQ4, IRQ5, IRQ7, IRQ10, IRQ11, and IRQ15) for selecting the IRQ number. You should use the I option to specify the IRQ for which the PCVAS is set. The MiniVAS does not have selectable jumpers for changing the IRQ number, but the I/O card in your computer may have such jumpers. Default: If this option is not specified, then the driver assumes the default IRQ for the selected COM port. Examples: I2 specifies IRQ2 I11 specifies IRQ11 I/O BASE ADDRESS: {Axxx} This option selects the I/O base address to use for communication with the PCVAS or MiniVAS. The address is given as a three digit hexadecimal number. The PCVAS has a set of dip switches labelled (A3 to A8) for selecting the I/O base address. Normally you do not need to specify this option because selecting a communications port using the C option selects a default I/O base address. Default: If this option is not specified, then the driver assumes the default I/O base address for the selected COM port. Examples: A200 specifies 0x200 A3D8 specifies 0x3D8 FRAME FORMAT: {F | T | L} F - Frame code T - Serial time code L - Longitudinal time code This option selects the mode used for search operations and record operations. Default: If this option is not specified, the driver assumes frame code (F) operation. TIME STANDARD: {N | P} N - NTSC (30 frames per second) P - PAL (25 frames per second) Default: If this option is not specified, the driver assumes NTSC (N) operation. VTR ID CODE: {Vaa} This option identifies the VTR connected to the MiniVAS or PCVAS using a two letter identification code. This two letter code can be found in your MiniVAS or PCVAS manual. Specifying this option causes the driver to initialize the MiniVAS or PCVAS with the given identification code. Default: If this option is not specified, then the driver assumes that the current VTR identification code stored in the MiniVAS's or PCVAS's memory is correct. Examples: VP7 specifies the Panasonic AG-7750 VSN specifies the Sony VO-9850 PREROLL TIME: {R#} This option specifies the preroll time for performing recordings. The preroll time can be set to a number of seconds from 1 to 20. To use the default preroll time of the MiniVAS or PCVAS, specify (R0). Default: If this option is not specified, the driver assumes that the default preroll time of the MiniVAS or PCVAS is correct. Examples: R5 specifies a 4 second preroll R10 specifies a 10 second preroll R0 specifies the default preroll time =========================================================================== Notes on the Operation of the Driver =========================================================================== If 3D Studio appears to have hung: --------------------------------- If 3D Studio appears to have hung during a frame search using Next Frame Forward, Next Frame Back, Goto, or a record operation using either Record or Disk-to-VTR, wait at least 15 seconds. For most operations, the driver has a time-out time of about 10 seconds. If after 10 seconds, the driver detects that something may be wrong, it returns to 3D Studio indicating that an error occurred in the operation. If after 15 seconds, you are not given control back, stop your VTR and wait another minute. The driver will wait a longer period of time before timing out when it is waiting for the cut-in signal and the ready to record signal.
