Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 5 of 27 PHYSICAL The control panel is 8” (W) x 8” (D) x 3.625” (H), and slopes from 1.250” height in front to 3.625” height in the rear. Two backlit alphanumeric displays separate cueing and menu operations from VTR status and timecode display. VTR control is always instant regardless of where the operator may be in the menu system. The VTR transport control keys are placed within easy reach of the high quality optical encoded Knob.
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 6 of 27 OPERATION BASIC OPERATION VTRs are selected by tapping corresponding VTR selection keys (F1-F10), or by double-tapping them for ganged operations (see VTR SELECTION below). Separate keys control the basic VTR transport functions: Play, Stop, Rewind, and Fast Forward. The SHTL key puts the VTR in high speed Shuttle mode at still speed; the Knob is then used to vary the Shuttle speed. Still Shuttle is resumed anytime the SHTL key is tapped.
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 7 of 27 VTR SELECTION The F1-F10 VTR Selection keys directly select any of the ten VTRs connected to the RM-4000 as the “current” VTR; the selected VTR is indicated by a solidly lit green (left hand) LED above the key. Commands are sent only to that VTR. A double-tap of any F-key enters the gang mode, indicated by one or more flashing green LEDs. In the gang mode, more than one VTR can be selected.
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 8 of 27 SYNCHED LOOPING Ganged VTRs may be looped continuously using the SYNC LOOP feature. Once enabled using the CUEING ITEMS, SYNC LOOP MODE menu, double-tapping the PLAY key causes synched looping to commence. The currently selected VTR or ganged VTRs first cue to the preroll point, then synch during the preroll period, then play until the OUT point is reached, at which point the process repeats.
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 9 of 27 begin two seconds after the GPI. The new edit location can be changed by taking control of the VTR and moving its location. GENERAL PURPOSE OUTPUTS (GPO) General purpose outputs are provided on the GPI DB15F connector. Each of the four GPOs can be programmed to fire relative to edit IN points and/or cycle tested (see GPO SETTINGS). GPOs can be fired manually by tapping HOME, then holding the numeric keypad 0 key while tapping the 1-4 keys.
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 10 of 27 MENU Many operational settings are adjustable by using the menu system. A separate MENU display is used so that VTR transport controls and status/timecode display are always active, even while navigating the menu. There are two exceptions to this: Some menu items use the KNOB, so it will not control speed while in such a menu item. Tap HOME to restore normal KNOB function. The other exception is the MISCELLANEOUS MENU ITEMS, VERSION AND TEST menu.
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 11 of 27 SET THE EDIT DURATION Tap the OUT (DOWN arrow) key while in the SET OUT mode to change the MENU display to the SET DUR mode. This allows you to define the edit length by DURATION rather than by an explicit OUT point. Tap the IN (UP arrow) key while in the SET OUT or SET DUR modes to return the MENU display to SET IN mode. Tap the OUT (DOWN arrow) key while in the SET IN mode to return the MENU display to the SET OUT mode.
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 12 of 27 RECORD SETUP Tap the HOME key followed by the SETUP key to enter the RECORD SETUP menu. The record mode in effect for the current VTR is shown on the upper MENU display line. Tapping VTR selection keys (F1-F10) show the current record modes for each VTR. To change the record mode of the currently selected VTR, use the UP/DOWN arrows until the desired mode is shown on the lower display line, then tap ENTER. The new mode will show on the upper line.
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 13 of 27 A feature is available that prevents playback from rolling past the end of a hard recording, see RECORD END STILL. OPEN ENDED ASSEMBLE EDIT Same as ASSEMBLE EDIT (see below) except the DURATION is ignored, and recording continues until the STOP key is tapped. At that time, the edit is ended and the timecode shown when STOP was tapped is marked into the event’s OUT point.
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 14 of 27 GPO SETTINGS GPI EDIT ENABLE Enables/disables the GPI backspace edit feature per VTR (default is disabled). If enabled and the VTR is set for HARD RECORD, when the VTR's GPI input goes active (low) a record command is sent to the VTR, when the GPI goes inactive a Stop command is sent.
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 15 of 27 through the disable/enable/cycle test modes, the UP/DOWN arrow keys to change between advance (-) and delay (+), and the numeric keypad to change the number of frames of advance/delay. Use ENTER to record each change, HOME to cancel. GPOs fire (drive low) for 1 video frame starting relative to the edit IN time. A delay of +000 fires at the edit IN point, -001 fires 1 frame before the IN point, and is normally used for auto transition purposes.
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 16 of 27 SAVE PERSONALITY Saves the current configuration in a personality register. Tap numeric keypad keys after selecting this item to show the names of the various registers. Tap ENTER when an unused register is seen (indicated by the name DEF for default). You may enter any 16 character name you wish by using the Knob to select a letter or number, and the RIGHT and LEFT arrow keys to move to other character positions (the name defaults to "REG X").
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 17 of 27 RECORD END STILL ADVANCE Changes the advance time, in frames, when the record end protect feature is activated. Change this setting if you don’t like where the auto stop feature stops the tape before the end of a crash recording. PROGRAMMED STILL MODE Causes the programmed still feature always to be enabled. Programmed still is a feature that causes normal or slow motion playback to slow to a still at the current event’s OUT point.
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 18 of 27 CUEING EE MODE Causes the VTR to output its input video while cueing. This is useful for dubbing operations: black video input to the source VTR is output to black the record VTR’s tails after a dubbing pass while the source VTR is cueing for the next pass. F7/F8 TRIM TIME (switch option only) Sets a timecode that is added to the current VTR's IN point by tapping F8, or subtracted by tapping F7.
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 19 of 27 OPER PREFS A submenu containing these operational preference items: SYNC PLAYBACK AUTO RESYNCH JOG FROM PLAY STILL AFTER CUE KNOB SENSITIVITY JOG USE VP CMD JOG MAX SPEED JOG SENSITIVITY STOP KEY FUNCTION SHUTTLE FORWARD AND REVERSE LIMITS SYNC PLAYBACK Enables/disables the synched playback feature.
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 20 of 27 STOP KEY FUNCTION Changes the function of the STOP key from the Stop command to Jog still. The default is still. SHUTTLE FORWARD AND REVERSE LIMITS Specifies the maximum Shuttle speeds, expressed in multiples of Play speed. This feature allows Shuttle speed to be limited to that witch provides the best compromise between speed and recognizable picture. It does not affect the Rewind/Fast Fwd speeds.
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 21 of 27 OPTIONS RS-232 OPTION The -RS option is an RS-232 interface that is used to control the VTC-4000 system remotely. VTR timecode and status, Menu display, and selected VTR information are accessible. Keystrokes can be simulated, and personality data can be downloaded and uploaded. The 9-pin-D connector on the BNA-1001-RS BUFNET/RS-232 adapter connects pin for pin to a 9-pin ‘D’ personal computer RS-232 port.
