INTRODUCTION

1.1 Description

The A60 is a real-time component digital recotding device, providing real-time playback in forward or reverse, variable playback speeds and random access to recorded material. The

A60 conforms to the 4:2:2 component digital standard and provides CCIR 601 input and output ports for interface to other CClR 601 equipment, making it ideal to use in various graphics environments.

Functionally, the A60 will perform like a playback or a record VTR, configured in one of two capacities; the standard configuration of either 25 seconds for the 525 version or 30 seconds for the 625 version, and the optional configuration of 50 seconds for the 525 version or 60 seconds for the 625 version.

The A60 has two CCIR 601 video input ports, either one may be selected for recording purposes. The Abekas A20 digital video encoder should be used if the input is to be originating from an analog component source, such as an RGB camera or a component VTR.

The A60 has several video output configurations present.

The program output is available both in the digital CCIR 601 format, and as an analog signal that is either RGB or Y, R-Y,

B-Y. Sync is available as a seperate output and may be added to the G or Y output. The preview output is available in either of the analog formats, and will only differ from the program output by the presence of the time code and frame position infonnation placed over it.

The

A60 may also have digital video transfer and remote machine control acomplished by using either the Ethernet or the SCSI ports. The Ethernet port follows the TCP/IP standard, and supports remote log in,

FrP and TELNET. The SCSI port is used typically for off line storage of video using standard 9-track magnetic streamer tape.

A60 Operations Manual Rev 1.2

1.1

1.2 Physical Description

In a 25 (or 30 if 625) second version, the A60 consists of a main electronics chassis with an integral Winchester disk drive assembly, and a control panel. A 50 (or 60 if 625) second version requires an additional disk drive assembly to be mounted near the main electronics chassis.

1.2.1 Control Panel

The compact control panel (4.5"H x 1l.75"W x 3.5"D) consists of a 5 digit frame number or time code display, a trackball, control keys and a numeric keypad. There is also a monochrome analog video output from the control panel to be fed to a black and white monitor for displaying system status and allowing access to the various features of the A60.

The 5 digit display will show the current position of the disks either as a frame number or as a time code number.

The trackball may be used for browsing through the material on the disks, as well as for system timing operations.

The numeric keypad allows instant access to a frame/field number, as well as providing a means to precisely set system set-up values.

The control keys consist of; disk control keys using normal transport command terminology, segment control keys for defining in and out points of a segment or a loop, and function keys for system set-up, configuration and access to the menu monitor functions.

1.2.2 Main ElectroniCS Chassis

The systems main electronics chassis (12.25"H rackmount) contains the printed circuit boards that control the various aspects of the A60, as well as a Winchester disk drive assembly that will provide 25 seconds (or 30 if 625) of time for the A60 system.

1.2.3 Additional Disk Drive Chassis (optional)

The optional disk drive chassis (7 1t H rackmount) will provide an additional 25 seconds (or

30 if 625) of time for the A60 system, making a total of 50 seconds (or 60 if 625) possible.

2: SYSTEM SET-UP

2.1 Initial System Connections

Below is a simplified system interconnect drawing of the A60. The component analog program and preview outputs of the system differ only in that the preview monitor will have the current disk position placed on it. These component analog outputs may be configured for either R, G, B or Y, R-Y, B-Y. See section 2.2 on the next page for more infonnation on this.

The control panel will have two connections made to it; the serial communications cable from the main chassis and a BNC cable to a monochrome menu monitor. To make these connections, it will be necessary to remove the rear cover of the control panel.

For more detailed infonnation on system connections, see the INSTALLAnON GUIDE found in the back of this manual.

2.2 Configuring the Analog Outputs

The Preview and Program analog outputs may be configured for either R, G, B, or Y, R-Y,

B-Y by setting the following jumpers on the A60's Computer board as shown. The unit is shipped as R, G, B with no sync on the G output.

NOTE: To change from the current configuration to a new one, even to just add sync, will require some level adjustments to be made. See section 8 of the INSTALLATION GUIDE for the procedeures to follow.

For R, G, B outputs ...

Remove jumpers W1, W2, W8, W10

Install jumpers W3, W4, W5, W7, W9

For V, R· V, BV outputs ...

Remove jumpers W3, W4, W5, W7, W9

Install jumpers W1, W2, W8, W10

For sync to be placed on the G or Y output, jumper W6 should be installed, in addition W5 should be installed for sync on the Y component There are two spare jumpers included with the board extractor that may be used if needed. The INSTALLATION GUIDE in the back of this manual should be consulted for more infonnation on connections to the A60.

2.3 Power-Up Procedure

A 25 or 30 second version of the A60 will have one power switch for the whole signal system chassis, located on the front lower right hand side of the unit. The additional disk drive chassis of a 50 or 60 second version will have its own power switch, located on the rear of its chassis. Ensure that both switches are in their off positions before plugging in the power cords.

The signal system chassis requires an outlet with a rating of 8 amps, the additional disk drive chassis requires an outlet of 5 amps. Plug the power cord from each unit into a properly grounded 110V AC outlet.

Locate the computer board in the A60 chassis, board 3, and note the position of the switch on the front edge. This switch must be set to its down position before applying power.

IMPORTANT

Before power Is applied, Insure that either a reference video signal Is connected to the rear of the A60, and the reference select switch on the front left of the 1/0 board (board 4) Is set to the left (external), or that the switch is set to Internal (to the right). This will ensure that there will be no problems during the power up process.

NOTE: USING WITH ENCODERS

The A60 has the ability to provide early output syncs for use with encoders that have a one line video delay, such as the Faroudja NTSC encoder. The selection of early or normal syncs is provided by DIP switch 18K located on the computer board. Section 3 of that DIP switch should be normally set to the OFF position for nonnal output sync timing, and set to the

ON position to provide syncs that are one line early with respect to reference.

The status of this mode may be checked by selecting the Miscellaneous menu, and looking at line 5.

3.1 Controls and the Display

The control panel consists of a 5 digit frame number or time code display, a trackball, control keys and a numeric keypad. The control panel will also feed a menu monitor that will display system status information.

The 5 digit display will show the current position of the disks either as a frame number or as a time code number.

The trackball may be used for browsing through the material on the disks, as well as for system timing operations.

The numeric keypad allows instant access to a frame/field number, as well as providing a means to precisely key in system set-up values.

The control keys consist of; disk control keys using normal transport command terminology, segment control keys for defining in and out points of a segment or a loop, and function keys for system set-up, configuration and access to the menu monitor functions.

3.2 Description of Keys

3.2.1 FUNCTION KEYS

This is the group of 5 keys along the upper left of the control panel. The fourth key is reserved for future use and is currently blank.

NORMPLAV

Performs two functions; when lit, indicates that the NORMAL PLAY mode is active, when not lit, the SEGMENT PLAY mode is active. Selecting this key will also display the

HOME

menu on the menu moniter, regardless of what menu is currently being displayed.

A segment may be defined only in this mode.

FREEZE

A toggle function that, when lit, will cause the output of the A60 to be frozen, even if the disk is still playing. The freeze will be either a field or a frame, based on the status of line

4 in the

SETUP

menu.

VIDEO IN

A toggle function that, when lit, will allow the selected video input to pass through the electronics and be presented directly at the output of the A60.

MENU

Has two operating levels, both affecting the position of the cursor on the menu monitor.

Pressing the MENU key directly will cause the cursor to drop down to the next menu line being displayed. The MENU key may be held down to create a repeating action, causing the cursor to scroll down the screen until the key is released. The cursor wi11loop back to the top of the display once the bottom is reached. A desired menu line may be specified by selecting that lines number on the numeric keypad and then pressing the MENU button.

3.2.2 TRANSPORT KEYS

This is the group of seven keys located at the lower left of the control panel.

VAR PLAY

Will play the disks at either a speed selected on the keypad or at the last speed used. A value of 0.500 would result in a speed that is half the play speed, a value of -5.000 indicating a speed of 5 times play speed in the reverse direction. The speed value will be displayed at the top of the menu monitor, once this mode is selected.

RECORD

Will "ann" the system for a recording to take place. Pressing the

PLAY~ starts the system recording. The length of the recording should be specified with the numeric keypad before the RECORD button is pressed. The record length that was last used will be used if none is specified.

+-JOG and

JOG~

Will provide a field or a frame step function through the recorded material, based on the setting of menu line 5 in the

SETUP

section.

Will playback a recording in either the forward or the reverse direction, normally at play speed. An alternate speed may be selected at the numeric keypad prior to pressing one of these keys. These keys will also initiate the playback of a segment or a loop.

STOP

Is used to halt the playback or record process, as well as to regain local control of the system when under external computer control.

3.2.3 SEGMENT AND LOOP KEYS

This is the group of six keys located to the right of the transport control keys.

SEGS PLAY

Will bring up the

SEGMENTS

menu on the menu monitor, which will then allow the editing of the segments present.

TRIM

Can be used in all modes to trim a number that had previously been entered. When using this function, the sign key (

+/. key), must be pressed to select the polarity of the trim value.

Should the sign key not be pressed, the value will be treated as an absolute and not a trim.

IN and OUT

Used to specify boundries for segments and loops.

LOOP

May be used to get the system to either playback a portion of the disk repeatedly as specified by the IN and OUT keys, or to establish a loop in a series of segments. In both cases, pressing either the V AR PLAY or a PLAY key will start the

LOOP playback.

SEG

Used while in the NORM PLAY mode. It should be pressed after in and out points have been established, if those points are to define a segment.

3.2.4 NUMERIC KEYPAD

This is the group of sixteen keys in the center of the control panel. A number that is selected here will appear on the menu monitor in a temporary register area located on the lower left of the screen .

. ENTER

Will allow the modification of a menu line in several different ways. Should the menu cursor be sitting on a non-numeric choice (e.g. an on/off function), pressing ENTER will cause the alternate choice to be made. Should the menu line be a numeric type, a number may be selected at the numeric keypad and entered by pressing ENTER. Pressing ENTER with no number specified by the numeric keypad will enable the current value to be altered by using the trackball.

FIELD

Is used to specify which field of a frame is to be used for a particular function (to GOTO, an IN value, etc.). The timecode display will indicate that field one is current by displaying a period between the groups of minutes, seconds, and frames. Field two will be indicated by a colon between the groups. This is true wherever the timecode mode is displayed, on the control panel display, the menu monitor display and the preview monitor display.

The frame display at the control panel (if chosen on line 6 of the

SETUP

menu), will show the number only for field one, and a period in the lower right hand comer for field two. The frame display on the menu monitor will display a n+n after the number if the frame display for the preview monitor will not indicate field one or two.

CLEAR

Will clear the temporary register on the menu monitor.

GOTO

Should be pressed after a time number (either timecode or frames, based on the display selected) has been keyed in, and will cause the disk to position itself to that point. It can also be used to go to a segment number, while in the

SEG PLAY mode.

+/-

Is used to enter a negitive value, pressed once will give a n+n sign in the temporary register, pressed twice will give a n -" sign. This is useful both when entering a new value (other than time), or when trimming an existing value or time .

• (decimal point)

Is used for certain setup parameters and speed values. This must not to be used for the entry of timecode numbers (they are automatically grouped).

A60 Operations Manual Rev 1.2

3.3 Menu Monitor

While the menu monitor is not absolutely required for nonnal system operation, it is necessaryJor most of the special functions (setup, segments, macros etc.).

Reganlless of the menu being displayed, there are a few things that will be constant. A box in the upper left hand comer will show the current disk position in timecode, and a box in the upper right comer will show the position in frames (a

"+"

indicating field two of the current frame). The space between these boxes will display various system messages while operating the A60, such as the variable play speed value or record length. The lower left of the monitor will always show a number as it is being selected on the numeric keypad, and will be referred to as the "temporary register" .

A60 Operations Manual Rev 1.2

3.3.1 THE HOME MENU

3.6

Temporary Register

The NORM PLAY key will bring up the

HOME

menu. It is from this menu that one of the branch menus may be selected in order to access a particular function.

The MENU key will directly affect the position of the cursor as it appears on any given menu. Simply pressing MENU will cause the cursor to drop to the next line present, once at the bottom it will loop back to the top line.

Selecting the number of a menu line with the numeric keypad and then pressing the MENU key will cause the cursor to jump directly to that menu line. Selecting a two digit number before pressing the MENU key can cause a jump to a menu line that is not part of the menu being displayed. The first digit specifies the

HOME

menu line number, the last digit specifies the actual desired menu line.

EXAMPLE: Menu line selection.

A60 Operations Manual Rev 1.2

Step 1

The

ENTER key may now be pressed to change the setting of this mode.

Step 2

Note the status of menu line

4)FREEZE.

Select the number 4 on the numeric keypad, and press the

MENU key. The cursor will jump to menu line

4)FREEZE,

and will also change its current status.

As a general rule, numerically selecting a menu line of a menu not currently being displayed

(using a two digit number) will change the menu display to that menu, park the cursor on that line, but not change that lines status. Numerically selecting a menu line of the menu that

is

currently being displayed

1Wl

change the status of that line (when applicable), as well as parking the cursor on it.

Once the correct menu line has been selected, a value may be pressed at the numeric keypad and entered, by pressing the

ENTER key, or, if the line is a non-numeric type, an alternate choice made by simply pressing the

ENTER key. If the line has a numeric type value and no value is selected at the numeric keypad, pressing ENTER will cause that line to become reverse video, and allow the trackball to alter the current value.

FIELD

The A60 will only send one field, creating the second field based on the setting of the

IN-

TERP ON/OFFline.

The

JOG keys and the trackball will position the disk one field at a time.

FRAME

The output will be the entire current frame (time displayed plus the next field). The

JOG keys and the trackball will position the disk one field at a time.

AUTO FRAME

The output will be the entire frame as above, however the

JOG keys and the trackball will position the disk one frame at a time, retaining the two field relationship established when this function was selected. The two field relationship will detennine whether the frame of video being output will consist of an odd and even field from the same frame, or the even field of a frame and the odd field of the next frame. The two field relationship may be changed by pressing the

+/-

key, the FIELD key, then the

GOTO key (this will position the disk ahead by one field, changing the two field relationship). This function may be useful for animation applications.

6) TIME DISPLAY

This will detennine whether the 5 digit control panel display will show the current disk position as a

TIMECODEvalue,

or as a

FRAMES

Section

4:

OPERATION

4.1 Playback Functions

The playback functions rely on a basic knowledge of the A60 controls and menu monitor usage. Section 3 "FAMlUARIZATION" should be consulted if necessary.

The INSTALLATION GUIDE in the back of this manual should be consulted if there are any questions as to how the A60 should be connected into your system.

Ensure the NORM PLAY key is lit for the following functions.

4.1.1 OUTPUT MONITORING

There are two video outputs from the system, a program output and a preview output. The program output is the main output, and should be dealt with as such. The preview output is essentially the same, with the addition of the disk position numbers (tiroecode and frames) being superimposed over it (see section 3.4 for infonnation on positioning these numbers on the screen).

4.1.2 FIELD OR FRAME OUTPUT

When the A60 is stopped, either a frame or a field may be displayed on the output. To choose the desired output, proceed as follows.

SETTING THE MACHINE MODE.

Step 1

Select the

Setup

line of the

HOME

menu, and press ENTER.

Step 2

Select line 5,

MACHINE MODE,

and press ENTER to select the desired mode.

FIELD

When in the field mode, only the current field will be the output to the monitor. This is useful when the video to be played back has a significant amount of motion, which may yield unacceptable amounts of intertield flicker should either of the frame modes be used.

FRAME

When in this mode, the current field plus the next sequential field will be displayed. Using

JOG or the trackball will cause the disk to be scanned at one field increments.

AUTO FRAME

This mode is useful when frame animation has been recorded onto the A60, as it will continue to keep the fields aligned as they were when

AUTO FRAME

was selected, even when using the JOG mode or the trackball to scan the disk.

In other words, the field type displayed (field one or two), will always be displayed, and the JOG and trackball will actually move the disk a frame at a time. The two field alignment may be changed by pressing the

+/-

key, the FIELD key, then the

GO TO key

(this will position the disk ahead by one field). The following drawing may help to visualize this.

4.1.3 INTERPOLATOR MODES

The Interpolator function setting will affect the output of the A60 at all times, except at the nonnal play speed (one times forward). Its affect will generally be most noticable when in still motion with field mode selected, orin the freeze mode with field selected, or when playing at a speed close to one times forward. To change its setting, proceed as follows.

CHANGING THE INTERPOLATOR MODE.

Step

1

Select the

Setup

line of the

HOME

menu, and press ENTER.

Step 2

Move the cursor to line 3,

INTERP ON/OFF,

and press ENTER to select the desired mode.

ON

Whenever it is necessary for the A60 to create a field to be sent to the monitor, such as in the freeze mode with field selected, or when playing at any speed other than +/-1 times play, the A60 will create the next field using an averaging method that could make the output subjectively better looking, with smoother diagonal transitions. There may be anoticable reduction in the sharpness of the fine detail while this is on.

OFF

The A60 will simply take the current field and make it the next field as well, whenever it encounters the above situations.

4.1.4 PLAY MODES

The forward and reverse PLAY keys provide real-time playback of recorded video.

Pressing the PLAY

~ nonnal real-time rate from the current position of the disk forward. The menu monitor will show "01.000", and the A60 will continue to play until the end of the time available on the disk(s) arrives, at which point it will go into the STOP mode.

A60 Operations Manual Rev 1.2

Pressing the

~PLA

The menu monitor will display "_01.000".

Pressing the STOP key will cause any playback to halt.

The PLAY speed may be altered from its nonnal value, by selecting the desired speed at the numeric keypad before pressing one of the PLAY keys. The acceptable range is

+/-

30 times play speed, with 0.001 (1.8 frames per minute 525, 1.5 frames per minute in 625) being the slowest speed available.

EXAMPLE: To playback at a speed of 1.5 times normal.

Step 1

Type in 1.5 at the numeric keypad.

Step 2

Press the PLAY

~

The menu monitor will display "01.500" during playback. Pressing the

~PLAY

2 would have caused the playback to go in the reverse direction, and the menu monitor to display" -01.500" .

Once playing back at the selected speed has concluded, either by reaching the end of the disk or pressing the STOP key, the play speed will revert to the nonnal speed of

+/-

1.000, the next time that the PLAY mode is selected.

4.1.5 THE VAR PLAY KEY

The V AR PLAY key has the same speed limits as the PLAY keys, with the following differences in their application. The direction of the speed must be specified at the keypad with the

+/-

key. The V AR PLAY key will remember the last speed used, with the exception of when either end of the disk is reached, at which time the preset speed will change to 0.000.

The V AR PLAY speed may be altered with the trackball while the A60 is playing back in the V AR PLAY mode.

4.1.6 THE JOG KEYS

The forward or reverse jog keys will provide a field or frame step function through the recorded video. The

MACHINE MODE

setting

(Setup

menu, line 5) will detennine whether the increment will be a field at a time

(FIELD

or

FRAME

selected), or a frame at a time

(AUTO FRAME

selected).

4.1.7 THE GOTO KEY

The GO TO key is used to instantly access the video at a specific timecode or frame number. The number used must be of the same type as the control panel is displaying (timecode or frames), and should be selected at the numeric keypad. Pressing GOTO once the number is selected will cause the disk to move, instantaneously, to the selected position.

4.1.8 THE LOOP KEY

The loop function provides a continuous playback loop of a given section of video on the disk. The video to be played back in the loop is specified by using the IN and OUT keys, or by simply typing the loop duration.

A60 Operations Manual Rev 1.2

The A60 will now run the loop as in the previous example.

Once a loop has been defined, and while the LOOP key is lit, the A60 in all playback modes will remain within the boundries of the loop. This includes when using the trackball.

4.1.9 TRIMMING LOOPS

A loop may be trimmed in one of three ways. A new IN or OUT point can be entered directly, or the TRIM key may be used as below.

EXAMPLE: Trimming a loop with the TRIM key and the numeric keypad.

Step 1

Define a loop using either of the previous examples.

Step 2

Select the TRIM key (it will start flashing), and on the numeric keypad press the

+1-

key to detennine the trim direction.

Step 3

Using the numeric keypad, type in the amount of the trim, and select the

IN or OUT point to be trimmed.

Keep In mind, that when using the trim function, the +/- key must be selected, or Instead of a trim, an entry of an absolute value will take place.

A60 Operations Manual Rev 1.2

EXAMPLE: Trimming a loop with the TRIM key and the trackball.

Step 1

Define a loop.

Step 2

EXAMPLE: To turn the LOCKOUT function off for the entire disk.

Step 1

Type "0" then press the IN key.

Step 2

Type "2500", then press the OUT key.

If frames are currently being displayed on the control panel, then the number "750" should be selected as the OUT point. Should the system have the optional additional disk drive, then "5000" for timecode or "1500" for frames should be entered.

For a 625 A60, the number keyed in for a 30 second version will be

"3000" for time code display, or "750" for frames. The 60 second version should have the number "6000" for timecode and "1500" for frames display selected as the OUT point.

NOTE: The out point of a lockout segment Is inclusive, unlike the out point of a regular segment.

A60 Operations Manual Rev 1.2

4.4.1 SEGMENT LIMITS

The segment play mode allows the creation of a random playback list of segments, each with its own in and out point, and with its own unique speed, if desired.

A maximum of 99 segments may be programmed at one time, however there are a few other limitations.

A single disk system (the 25 or 30 second version of the A60), will generally need to freeze the output video while the disk drive is seeking from the end of one segment to the start of the next. The maximum amount of time for this is 2 frames, the actual amount will depend on how far it must seek.

A two disk system (the 50 or 60 second versions), within certain limits, will not have this problem. A maximum of 24 segment starts per disk (48 total) will perform seamless transitions between segments. The disk from which a segment will start is determined by the

IN point timecode. "00.00.00" to "00:24:29" would be disk one in a 525 system, anything above this would be disk two. The 625 limits would be from "00.00.00" to "00:29:29" for disk one. Any segments above the limit of 24 on a drive will have the possibility ofa freeze taking place, as in the single disk system.

4.4.2 DEFINING SEGMENTS

The NORM PLAY mode must be active in otderto define a segment. A segment is defined by selecting an IN and an OUT point, and then pressing the SEG key.

EXAMPLE: Defining a segment.

Step 1

Ensure the NORM PLAY mode is active.

Step 2

Using the trackball or GOTO key, select the desired start point of the segment.

Step 3

Press the

IN key to define this as the start point.

Step 4

Now position the disk for the end point.

Step 5

Press the OUT key to define this as the out point of the segment.

Step 6

Press the SEG key. The bottom of the menu monitor will flash that a segment has now been defined, as well as the number of that segment.

Step 7

Repeat until there are several segments defined.

4.4.3 THE SEGMENTS PLAY MENU

Selecting the SEGS PLAY key will bring up the

SEGMENTS PLA Y

menu. The top of the display will show a maximum of2 segments, using the trackball will scroll through the other segments. The bottom of the screen will show the total number of segments present.

COpy

SEGMENTline).

The following menu lines will affect the top segment (shown highlighted), that is being displayed.

1) INSERT SEGMENT

This menu line will allow a previously deleted segment to be re-inserted at a different location in the segment list. The segment will be placed before the highlighted segment.

2) DELETE SEGMENT

This menu line will be used to delete or move a segment. A segment that is deleted will be retained in memory, and may be placed elsewhere in the list by scrolling to the desired location (using the trackball), and selecting the

INSERT SEGMENTline.

3) COpy SEGMENT

This will make a copy of a segment, which may be placed elsewhere in the segment list by using the trackball or the

GO TO function and the

INSERT SEGMENT

menu line.

4) SEGMENT SPEED

The speed of a segment is by default the normal play speed, the reverse direction will be assumed if the IN point of the segment occurs after the OUT point. Using this menu line, the actual speed may be altered for a particular segment, by selecting the new speed on the

A60 Operations Manual Rev 1.2

4.11

keypad and pressing ENTER (assuming the cursor is sitting on the

SEGMENT SPEED

Position the segment list to the segment whose speed needs to be changed.

Step 2

Select the new speed for the segment at the numeric keypad.

Step 3

Position the menu cursor over 4)

SEGMENT SPEED,

and press

ENTER.

Should a negative speed be selected, the IN and OUT points of the segment will be reversed.

Should the segment list be played back at a speed other than one times play, the segments with non-nonnal speeds will have their speeds altered proportionately.

4.4.11 SEGMENT PAUSE

A pause may be placed at the end of a segment by using this function.

The pause will occur at the end of the segments playing, whether it is played in the forward or reverse direction.

EXAMPLE: Installing a pause.

Step 1

Position the segment list to the segment to have a pause placed after it.

Step 2

Position the menu cursor over

5)

SEGMENT PAUSE, and press

ENTER.

A60 Operations Manual Rev 1.2

A "P" will now be placed in that segments line. When playing the segments list, the A60 will STOP after the segment with the pause is encountered, and may be restarted using any of the nonnal transport keys.

4.4.12 TRIMMING A SEGMENT

While in the

SEGMENTS PLA Y

mode, the IN and OUT points for a segment may be trimmed.

EXAMPLE: Trimming a segment.

Step 1

Position the segment to be changed to the highlighted area of the menu monitor.

Step 2

Press the TRIM key. A number may be selected at the keypad, along with the

8) EDIT MACRO

This should be selected to enable menu line 6)

DELETE STEP.

4.5.2 CREATING A MACRO

When

CREA TE

is selected along with a macro number, the top of the menu monitor will say "«<ready to record»>". From this point until the end of the learning process, the words "MACRO LEARN" will appear in the lower right comer on all menus.

The easiest way to teach the A60 a macro is to simply perform the task once while in the learning process. Should the task include a record command, that function will not actually be performed, but will be remembered as part of the macro. Almost all functions within the

A60 are available to be part of a macro.

It is possible to create a macro that runs in continuous loop fashion. Instead of selecting

END

as the last step of a macro that is being created, select

EXECUTE,

the number of this macro, and press ENTER. By substituting the number of a different macro after the EX-

ECUTE

command, it is possible to have one macro call up another and run it.

1) REMOTE BAUD RATE

This will allow the selection of either 9600 or 38400 as the baud rate for remote communications utilizing the SMPTE port.

9600

This should be used with certain models of the CMX editor series.

38400

This should be used whenever the remote port is configured for certain CMX editing systems, the Abekas A53D digital special effects system, SMPTE based devices, or the SONY

900 and 9000 editors.

2) REMOTE PROTOCOL

This assigns the remote port to a specific communications protocol.

PORT OFF

This will disable the remote port completely, and should be selected if no devices are connected to the port.

CMX 12

(CMX I-squared)

This will enable communications with a CMX editor. The baud rate above should be set to match the type required by the CMX model to be used.

A53D

This will configure the remote port to communicate with an Abekas A53D digital special effects device. The A60 will cue up and run the current effect on the A53D, which would make creating a precisely timed move easier. The communication cable between the A60 and the A53D would need to be specially wired due to both devices being "slaves" for serial communications. See the wiring diagram in the INSTALLATION GUIDE. The baud rate should be set to

38400.

SMPTE

This will configure the remote port for usage with those editing systems utilizing the SMPTE standard for communications. The baud rate should be set to

38400.

SONY

This will enable the Sony 900 or 9000 editors to control the A60. The baud rate should be set to

38400.

3) EDIT FIELD

This will specify the field to which the A60 should begin recording on when an editor specifies a given frame number, since typically an editor will not specify a field. The choices are FI (field one) and F2 (field two).

5) TAPE BACKUP LENGTH

This is a function to be used with a standard 9-track magnetic streamer tape device to provide a tape backup of the video on the disk. This menu line allows the specifying of the amount of disk time to be sent to the tape device. The maximum amount of time is 10 seconds with

3600' of tape, a

2400' tape will give about 7 seconds.

A density of

6250

BPI (Bytes Per

5.2 SERIAL REMOTE CONTROL

The A60 may be directly connected to a variety of editors, and will appear as either a source or a record machine.

The Remote menu lines specifying the baud rate, protocol, and edit field should be configured correctly. See section 5.1 for infonnation regarding these menu lines.

The A60 will not actually preroll as a VTR would, it will send the appropriate numbers to the editing system to make it think that a preroU has taken place. This means that the first

5 seconds of the disk do not have to be sacrificed for this putpose. However, the earliest time that may be specified is 00:02 (with

FIELD

5.3 ETHERNET

The A60 supports both the remote control and the transfer of video provisions of the Ethernet system.

The

A60 will appear to be a host computer that files (video) may be transferred to or from.

Installation requires simply connecting the A60's ETHERNET port to a transeiver which provides the interface to the Ethernet Coax.

The video to be transfered may be either in the R, 0, B or Y, R-Y, B-Y fonnats, and may be either a field or a frame.

Remote control and video transfer may be accomplished usingTELNET, FrP, and the UNIX

'r' commands ('rep', 'r1ogin', and 'rsh').

The

A60 needs to be assigned an IP address in order for communications to begin. The

MIs-

8: INSTALLATION GUIDE

8.1 Physical Mounting

Both the signal system chassis and the optional additional disk drive chassis are supplied with rack slides for installation into a standard 19" equipment rack. The signal system chassis, with it's internal disk drives, will require 12.25" of rack space, the optional additional disk drive will require 7" of rack space.

The additional disk drive should be mounted on top of the main chassis to allow more efficient cable routing.

NOTE: Exercise caution when lifting these chassis, as they are approximately 1 OOlb. each.

8.2 System Interconnects

8.2.1 Signal System to Disk Drive Connections

A 25 or 30 second version of the A60 has all of the system to disk drive connections done internally.

A 50 or 60 second version of the A60 will have an external disk drive chassis that will need to be cabled using Abekas supplied cables. To ensure proper connection to the appropriate chassis, each connector on the 7-50 pin ribbon cables is keyed. Use only Abekas supplied ribbon cables for the interconnects between the chassis.

CONN"ECTIONS

8.2.3 Control Panel to Signal System Connection

The A60 control panel communicates with the signal system by means of an RS422 link, modified with the addition of carrying the control panel power. The control panel cable will have a 15 pin connector on one end, this should be connected to the signal system socket labeled KEYBOARD. The other end of the cable has a 9 pin connector and will connect directly to the control panel. The back cover of the control panel will have to be removed to gain access to the 9 pin socket. There is a grommet provided for routing the control cable· through, once the back is replaced on the control panel.

NOTE: The cable length between the control panel and the signal system chassis must be less than 200 feet, In order for the +24 volts sent from the signal system to be able to power the control panel.

Should a distance greater than this be necessary, up to 2000 feet, a user supplied external power supply at the control panel will need to be utilized. A +12 volt supply at 2 amps will be sufficient. See section

8.4.2 for pin-out information should a custom cable be necessary.

8.2.4 Control Panel to Menu Monitor Connection

The BNC connector present on the left side of the control panel should be connected to a monochrome monitor, with a user supplied 75 ohm cable, for the display of operator menus.

The video out of the control panel should be terminated with 75 ohms. It may be necessary to slightly alter the scanning height of the monitor to get the entire menu to display.

NOTE: To access the BNC connector on some control panels, it is necessary to remove the back as was done for the above communications cable. The connector Is located along the lower edge of the control panel. There Is a second grommet provided for the routing of the coax cable out of the back of the control panel.

A60 Operations Manual Rev 1.2

8.3

8.3 Video Connections

8.3.1 Reference

A 2 volt p-p analog composite sync signal should be connected to the left BNC connector on the back of the signal system chassis labeled REF LOOP. The right BNC may be used as a loop through, however when not used as such it should be terminated in 75 ohms.

8.3.2 Video Inputs

There are two digital CCIR 601 video inputs supplied with the A60. For use with an analog component signal, the Abekas A20 may be used. The video input to be used is selected at the control panel by selecting the

SETUP

menu from the

HOME

menu, and selecting on line 9 the input desired. For more information, see the A60 OPERATIONS manual.

8.3.3 Video Outputs

There are two digital CCIR 601 video outputs supplied with the A60, as well as a component analog program output and a component analog preview output. The preview output will differ from the program output only by the addition of a super-imposed timecode and frame display. The analog outputs are configured as ROB without sync, and may be configured as either RGB or Y/R.-Y/B-Y, by setting the following plug-in jumpers located near the front of the A60's I/O BOARD.

NOTE: If the configuration Is changed from Its current setup, some level adjustments will have to be made. See section 8.8 of this INSTALLATION

GUIDE for the procedures required.

For RGB operation;

Install jumpers W3, W4, W5, W7, and W9

Remove jumpers W1, W2, W8, and W10

For VIR-V

IB-

V operation;

Install jumpers W1, W2, W8, and W10

Remove jumpers W3, W4, W5, W7, and W9

8.3.4 Analog Sync Outputs

There are two BNC outputs on the back of the A60 labeled SYNCS OUT, both of which contain composite analog sync at 2V p-p. It is also possible to have sync added to the G or

Y analog component outputs by installing ajumper at W6, and at W5 ifforthe Y component, on the A60's I/O BOARD.

8.3.5 Early Output Syncs

The A60 has the ability to provide early output syncs for use with encoders that have a one line video delay, such as the Faroudja NTSC encoder.

The. selection of early or normal syncs is provided by DIP switch 18K located on the A60's

COMPUTER BOARD. Section 3 of that switch should be normally set to the OFF position for normal output sync timing, and set to ON to provide syncs that are one line early with regard to reference.

8.4 A60 Operations Manual Rev 1.2

8.4 Detailed Pin-Out Information

8.4.1 Keyboard Interconnections

The following is a pin listing of the cable used to interconnect the A60 control panel with the signal system chassis. These interconnections are identical to other Abekas equipment, including the A42, A52, A53D, A62, and A64. It should be noted that separate wires are used for chassis ground, signal ground, and the phantom power return. These grounds are at differing potentials and should not be interconnected at any point. The cable used is 22 gauge, 9 parallel conductors, unshielded

'The

Belden equivalent part number is 9423. The connectors used are a 15 pin D male for the signal system end, and a 9 pin D male for the control panel end.

The RS422 communications may have a cable length of up to 2000 feet, however, if power is also being sent along the cable, there is a length limit of 200 feet.

If is necessary, the control panel will need to be powered locally with a user supplied power supply. A +12 volt at 2 amp supply will be sufficient.

8.7 GPI Connections

The A60 supports 8 independent GPI (General Purpose Interface) lines. Four are inputs that may be used to trigger a function in the A60 from an external device, the four others are outputs that may be used to trigger an external device from the A60. The RS232 connector on the rear of the A60 is used to make the connections. For the pin out information of the RS232 connector, seepage 8.7 of this INSTALLATION GUIDE. For operational information, see the

REMOTE OPERATION section of the

A60 OPERATIONS MANUAL.

8.7.1 GPIINPUTS

There are two methods for connecting to the A60 OPI inputs, a

"dry" method that requires only a switch to be placed across two pins, and a method that requires an external voltage to operate.

Switch 24D on the A60' s Computer board will select which of the two methods is active for a particular OPI Input line.

8.8 ANALOG OUTPUT CONFIGURATION

8.8.1 INTRODUCTION

The A60 has the provisions for component analog video out of the unit. There is a program output and a preview output, the preview being identical to the program with the exception of having the disk position, in both timecode and frames, placed over it.

These outputs may be configured in either an R,G,B fonnat or a Y,R-Y,B-Y fonnat. Sync may be added to the G or Y component if desired. Sync is also available separately through two BNCconnectors at the rear of the A60.

The A60 is shipped configured for R,G,B with no sync on the

G component. To change this configuration, some jumper changes and level adjustments will be necessary. Locate the desired configuration and perfonn the steps listed.

NOTE: Any adjustments made should affect both the program and preview outputs Identically. Should there be any problem with the preview outputs not matching the program outputs, see the Technical

Manual for Information on preview adjustments.

NOTE: The oscilloscope used should have the 20Mgz filter turned on.

In addition, It may be necessary to externally trigger It from a horizontal signal.
