KEY(OPCS) Optical Printer Control System KEY(OPCS) NAME key - shoot camera/projector frames by button control USAGE key [no arguments] DESCRIPTION KEY(OPCS) gives the operator button controls to run camera, projector, and fader for simple shooting. These are the defaults defined by the KEYFUNC(OPCSDEFS) command in the OPCSDEFS.OPC file: _ F1 = projector2 continuous run fwd | F2 = projector2 continuous run rev | PROJECTOR2 SHOOT F3 = projector2 fwd single frame | F4 = projector2 rev single frame _| _ F5 = projector1 continuous run fwd | F6 = projector1 continuous run rev | PROJECTOR1 SHOOT F7 = projector1 fwd single frame | F8 = projector1 rev single frame _| _ F9 = camera continuous run fwd | F10 = camera continuous run rev |CAMERA SHOOT F11 = camera fwd single frame | F12 = camera rev single frame _| _ 1 = run positive ratio shoot | 2 = run negative ratio shoot | RATIOS 3 = set ratio to new values _| _ 4 = set projector2 counter | 5 = set projector1 counter | COUNTERS 6 = set camera counter _| _ 7 = set fade in | 8 = set fade out _| FADES _ 9 = set dissolve in | 0 = set dissolve out _| DISSOLVES _ - = close fader | = = open fader _| OPEN/CLS _ BACKSPACE = seek pro/cam _| CAPPED SEEK HOME = unlock (deenergize) motors ESC = quit to OPCS command line It is advised you use a keyboard template. A screen menu with all the above information is ugly, and would contend with the counter display, so the screen for the KEY command is mostly empty, except when prompting for data. ♀ On most IBM keyboards, function keys (F1 - F12) are arranged across the top of the keyboard in 3 groups, 4 keys per group. These groupings correspond to the three shutter motors from left to right: Motor Controlled Func Keys ---------------- --------- Aerial Projector F1 - F4 Main Projector F5 - F8 Camera F9 - F12 In each group, two keys control forward/reverse and shoot as long as you hold the key down, the others shoot forward/reverse single frames. CAVEATS You can use KEYFUNC(OPCSDEFS) to define external port bits to rig up your own buttons on the printer to control the motors, as well a redefine the above keys. You can also tie your own custom commands to buttons and keys. EXAMPLE. To define the TAB key to invoke a DOS dir command, then put the following in your OPCSDEFS.OPC file: keyfunc -add "! dir ! pse -noabort" 0060 ff 0f 0060 80 80 ---------------------- ---------- ---------- | | | | | Tab up keycode OPCS command to run Tab down keycode Then invoke the KEY(OPCS) mode. When you hit TAB, a directory listing will appear, then you will be prompted to hit a key, then you're returned to the key mode.
