VTRs connectable to the unitA 9-pin remote control connector is provided.It is possible to connect the following VTRs.

U-matic VTR VO-9850/9850P,BVU-800/900 series

Hi 8 VTR EVO-9850/9850PS-VHS VTR SVO-5800/5800PBetacam SP VTR UVW series, BVW series,

PVW seriesDVCAM VTR DSR series

CTL/time code/RTC (relative time code)selectionYou can select a CTL signal, time code or RTC(relative time code) for editing. When RTC isselected, the time code is used as an edit reference andits progress is counted as CTL on the time counter.RTC can be used to determine how far the desired tapepoint is from the IN point as it can be reset in the samemanner as a CTL.

Pinch on delay time learning capabilityThe unit can detect the pinch on delay time of theconnected VTR and hold this data for a week evenafter the power is turned off. Therefore, the operationwith the connected VTRs is very smooth and nodiscontinuity of the picture is produced by this unit.

Various edit functionsIn the assemble mode, the video signal and audiosignals (A1 and A2) are edited together at the sametime.In the insert edit mode, they can be edited separately.The unit can also perform the split edit. Therefore,you can set the audio IN point independently from thatof the video channel and vice versa.Materials you are to edit can be previewed and thosethat you have edited already can be reviewed.

Easy data pre-settingYou can easily preset various data, such as the prerolltime and the edit timing, needed for editing on thefront panel.

Quick tape access to the scene to editVariable speed of playback functions in the shuttlemode and jog mode enable you to locate the edit pointmore quickly.

Synchronization with the connected VTRThe REF.VIDEO IN connector allows the unit tosynchronize with the connected VTR. Therefore, theunit can perform absolutely precise editing.

Control of the VTR with the dynamictracking™ functionWhen the VTR which has the dynamic trackingfunction is connected to this unit as the player VTR,this unit can edit the picture in the variable speed.

Error indicationsThe unit indicates the error by displaying the errornumber on the time counter and outputting a warningsound. You can understand right away what kind oferror has occurred and what you should do.

Rack mountableThe unit can be mounted on the RMM-450 rack mountmetal which is designed for a standard 19-inch rack,and on the SU-500 series system console by using theSU-450 double size table.

Insert edit using a new tapeA CTL signal must be recorded on the tape to be recorded as indicated onthe illustration below.

The CTL signal can be recorded by connecting a video camera or standardvideo signal generator to record its output signal continuously.

Assemble edit using a new tape

When assemble edit is performed from the beginning of a new tape or aftera blank on the tape, CTL signal must be recorded as follows:

What is the assemble edit?Video, audio and CTL signals are edited simultaneously in the assembleedit mode. If new material is edited on a previously recorded tape in thismode, the fully erased portion remains at the OUT point, and thecontinuity of the picture cannot be kept at that point. The assemble edit isuseful to edit new signals scene by scene in sequence.

What is the insert edit?Video and/or audio signals are edited according to the CTL signals whichare already recorded on the tape. Even if the new material is edited on apreviously recorded tape in this mode, the continuity of the picture can bekept. The insert edit is useful to replace the video or audio signal of therecorded tape or to add video signal to the tape which has only audiosignals recorded and vice versa.

Determining the Edit Points — IN/OUT Points

Using the search dial

The search dial is convenient to use to search for the desired tape point.The search dial can playback the tape in the reverse and forward directionsat various speeds. Therefore, you can find the scene for the desired editpoint easily. The search dial operates in the shuttle or jog mode, and youcan change the mode by simply pushing in the dial. The shuttle mode hasthree click positions, and the jog mode has no click position.

Shuttle modeThis mode is useful to search for an approximate edit point. The playbacktape speed depends on the position of the dial. The tape runs within 1/30 to10 times the normal speed.

Jog modeThis mode is useful to precisely find the frame of a desired edit point. Theplayback speed depends on the speed at which you rotate the dial. Thetape runs within 1/30 to 3 times the normal speed.

Using the PLAY/REW/FF buttons

You can search for the desired tape point by pressing the PLAY/REW/FFbuttons.Press the STILL button to stop the tape when you find the desired scene onthe monitor.

2-8. SAFETY CHECK-OUT

After correcting the original service problem, perform thefollowing safety checks before releasing the set to thecustomer :

Check the metal trim, “metallized” knobs, screws, and allother exposed metal parts for AC leakage. Check leakageas described below.

LEAKAGE TEST

The AC leakage from any exposed metal part to earthground and from all exposed metal parts to any exposedmetal part having a return to chassis, must not exceed 0.5mA. Leakage current can be measured by any one of threemethods.

1. A commercial leakage tester, such as the Simpson 229or RCA WT-540A. Follow the manufacturers’instructions to use these instruments.

2. A battery-operated AC milliammeter. The DataPrecision 245 digital multimeter is suitable for this job.

3. Measuring the voltage drop across a resistor by meansof a VOM or battery-operated AC voltmeter. The“limit” indication is 0.75 V, so analog meters musthave an accurate low-voltage scale. The Simpson 250and Sanwa SH-63Trd are examples of a passive VOMthat is suitable. Nearly all battery operated digitalmultimeters that have a 2 V AC range are suitable.(See Fig. A)

SECTION 3TROUBLESHOOTING

3-1. GENERAL

No electrical adjustment is required in this machine.Use of a simple checker and a built-in test program cancheck all operations.A test program activating method and checking items aredescribed below.

3-1-1. Keyboard Check

Turn ON the POWER switch while pressing the LEARNand ASMBL keys at the same time.Checking items :

LED ON/OFFNon-locking switch operationLocking switch operationJOG/SHUTTLE operation of Search DialRS-232C line operation of KSW-1 boardBackup data (LEARN data) verificationROM and RAM check by CPU on KSW-1 board

3-1-2. Backup Function Check in Keyboard

Turn ON the POWER switch while pressing the LEARNand A1 keys at the same time.Checking items :Backup function check by CPU on KSW-1 boardThe “Error” is displayed when the POWER switch isturned ON at the first time (or when the backup capacitorC305 on the KSW-1 board is discharging).Further error display is not made if the backup function isnormal.The capacitor can afford to provide backup for at leastseven days.

3-1-3. CPU-3A Board Check

Turn ON the POWER switch while pressing the LEARNand A2 keys at the same time.The CPU board is automatically checked.(Start by EJECT key on the RECORDER side.)If a fault is found, the operation is stopped immediatelyand the error code is displayed.For this purpose, the service tools are required.

3-1-4. Software Operation Check and REF.VIDEO Circuit Check

Turn ON the POWER switch.D219 (CHECK3 LED) on the CPU board blinks by thesoftware. In addition, D217 (CHECK1 LED) blinks whena signal is entered into the REF. VIDEO IN terminal.

3-1-5. Address Bus Check (Power ON afterS201 OFF)

Turn OFF the 8-bit DIP switch S201 on the CPU boardthrough it is usually set to ON position. The CPU thenexecutes NOP (00) since the data bus on the CPU board isisolated from devices other than CPU and pulled down bya resistor. At this time, the address line shows simpleincrements. (However, a refreshed address is assigned toA7 to A15.)Observation of a waveform on the address line with anoscilloscope makes fault identification easier.
