Installation

System Setup Planning

Before you install and configure the KCU, there are several
fundamental issues to consider.

Power

An AC outlet is required for the KCU. If more than one piece of
equipment will be connected to the AC outlet, use a surge­protected power distribution strip as an adequate extension cable.

Cabling

The KCU requires communication and power cabling. Careful
connection and routing of cables will ensure a quick and successful
installation. Power supply and Lynx-2 cables are included with
the KCU.

Power On Initialization

Installing the KCU

Cabling

The KCU is supplied from the factory ready for initialization. All
parameters of the KCU are stored in RAM, and are restored on
subsequent power ups.

On power-up, the KCU will automatically poll any Lynx-2 module
that is communicating on the RS422 serial bus. At this point, the
KCU is ready to address each module within a group, or
individually, for machine control.

Because the KCU is a free-standing controller, installation offers
configuration choices. The KCU and its power supply have been
designed with the utmost in versatility, which provides a simple
path for any future upgrade requirements your facility might
require.

Cable connections are critical. Bad or poorly routed cables are
often the cause of installation problems. It is essential that the
correct, high quality cables are used to ensure reliable, trouble­free operation.

Setting the System Reference

Before using the KCU, determine the system speed reference your
machines will be locked to. When a system reference is selected,
the KCU synchronizes all Lynx-2 modules, including the master, as
slaves to this timing reference. This provides fast and stable lock­ing because each machine is independently controlled and locked.

When a system reference is selected at the KCU, verify that the
selected reference is properly connected to every Lynx-2 module in
the chain.

There are four reference selections available:

Int Xtal Lynx-2 Module internal crystal

Ext Vid External composite or black burst video sync signal

Mains AC mains frequency

VSO Variable speed, determined by varispeeding the master

Getting Started

transport

The KCU reference defaults to External Video. The system speed
or rate is determined by the video source applied to the Lynx-2
modules, either 29.97 Hz for NTSC or 25 Hz for PAL/SECAM.
Unless you use a different frame rate, for example 30 Hz, use this
reference to get started.

System reference parameters may be changed in the SYS options
menu. See KCU Options Menus in this chapter for details.

Initializing Lynx Communication

Getting Started

Reference Sync Point Register

The KCU uses the time code value in the Reference Sync Point
register to calculate offsets for any source machines with source
sync points. Offsets are calculated using the following equation:

Offset = Source Sync Point - Reference Sync Point

If you change the reference sync point value (either in Trim mode
or by entering a new value), the KCU recalculates and stores the
correct offset for all source machines with active source sync point
values.

Accessing the Reference Sync Point Register

The calculator [REF] key provides access to the Reference Sync
Point register during store, recall, and trim operations.

The special function [REF SYNC] key provides access to the
Reference Sync Point register.

Clearing the Reference Sync Point Register

Press [CLR] and [REF] simultaneously to clear the Reference Sync
Point register.

Press and hold [CLR] and press special function [REF SYNC] key
to deactivate the value in the Reference Sync Point register
without actually clearing the value. The [REF SYNC] key is no
longer lighted.

Source Sync Point Register

The [SYNCP] key provides access to the Source Sync Point
register for a specified machine. The KCU uses the time code
value in the Source Sync Point register of each machine to
calculate an offset for a source machine relative to the reference
sync point. Each source machine in the system has a separate
sync point register. The reference machine can not have a Source
Sync Point register.

The offset is displayed as a positive or negative number with an
absolute value of 12:00:00:00 (12 hours) or less. The offset is
calculated using the following equation:

If the source sync point has a higher time code value than the
source sync point, the keyboard displays the offset as a small
negative number. For example, -1:10:00:00 is displayed rather
than the equivalent large positive number 22:50:00:00.

machine time code. The edit in point is used to calculate source
machine offsets if no reference sync point is entered.

Getting Started

The special function [IN] key is illuminated whenever there is an
active value in the In Point register.

If no in point is set, it will be calculated automatically when you
enter an out point and a duration. The equation for calculating an
in point is:

In Point = Out Point – Duration

The KCU calculates an in point value based on the current
position of the source machine and the source machine offset
value. This occurs if a source or slave transport is soloed when
you press the special function [IN] key (the reference machine
time code is not running at the time). The in point value is
calculated in the reference time code type.

If there is no active value in the In Point register when you select

of the current programmed edit. The value is expressed in terms
of the master machine time code.

4-10 09/08/00

Keyboard Control Unit

Getting Started

The out point is calculated and stored automatically when you
enter an in point and a duration. The equation for calculating an
out point is

Out Point = In Point + Duration

The special function [OUT] key is illuminated whenever there is
an active value in the Out Point register.

If there is no active value in the Out Point register when you
select an edit mode, the message Warning: open end is displayed
and the KCU performs an open-ended edit. In an open-ended edit,
the duration shows as open during the preroll, and is incremented
a single frame at a time during the actual edit period.

If a source or slave transport is soloed when you press the special
function [OUT] key (the reference machine time code is not
running at the time), the KCU calculates an Out Point value in
the reference machine’s time code based on the current position of
the source, or slave, machine and its offset value.

Altering the value of the duration also causes the out point to be
recalculated. Altering the out point causes the duration to be
recalculated.

Accessing the Out Point Register

The calculator [OUT] key provides access to the Out Point register
during store, recall, and trim operations.

Press the special function [OUT] key to store the current reference
machine time code value in the Out Point register.

The KCU can simultaneously control up to six tape machines.
When the transport control keys are pressed, all machines
assigned to the group will chase and synchronize.

When the KCU is first initialized, no machines have been placed
in the group.

Press [SOLO] and the appropriate machine select key (A-F). The
transport control keys control only the selected machine. All other
machines remain in their current state of motion. To select a
different machine, press the appropriate machine select key (A-F).

The [GEN] key is also available with KCU 300 series software.
[SOLO GEN] is normally used only to generate time code, but it
can be used to control a time code-only chase device.

Locking in a Group

Before locking machines in a group, it is good practice to let each
machine resolve and lock by itself. By doing this, each Lynx-2
module remembers its transport type and subsequently locks the
transport considerably faster.

The KCU display indicates whether the machine and group are in
lock. To lock machines in a group,

Getting Started

Using Offsets

Offsets are used if the time code on two or more tapes does not
match. For example, if tape A starts at 00:00:00:00 and tape B
starts at 02:00:00:00, a record in point of 00:30:00:00 cannot be
correct for both machines. Use the KCU to enter offsets to compen­sate automatically for the time code difference between the tapes.

The offset is the difference in the number of frames between the
reference and slave or master tape at the point where they are to
be synchronized. For example:

02:00:00:00 (Slave time code)

-01:00:00:00 (Reference time code)

=+1 hour offset (number of frames)

A positive offset indicates that the source machine time code
position is in advance of the reference machine time code position.
If the machine selected is the reference tape machine, the offset
register value will be zero since offsets are only applied to slave
machines.

Setting an Offset

When a machine has an offset, the corresponding machine AUX
LED in the STATUS display will light.

Offsets cannot be set for the reference machine.

The KCU always calculates a machine offset from the reference
machine. The KCU indicates the reference machine with an *, the
master machine with a capital letter and slave machines with
lower case letters. By default, the first machine selected into the
group is the reference master machine, indicated by “A*”.

To change the reference machine, repoll the KCU. Press and hold
the [GRP] key, and reselect the machines. If required, the
reference machine can be different from the master machine,
allowing the master machine to have an offset from the reference
machine. (See Changing the Master Machine section.)

In the following example, A is the master reference machine and B
is the slave machine. A and B are grouped together.

1. Press [SOLO] + [A] to solo the master A machine.

2. Press [PLAY].

3. Press [STOP] to locate the machine to a point and stop.

4-16 09/08/00

Calculating Offsets Using Sync Points

The special function keys may be used to shortcut certain
keystrokes on the KCU. In this example, the [REF SYNC] and
[SRC SYNC] keys will automatically capture and store sync points
to the individual machines.

1. Press [SOLO], then [A] to Solo the master machine.

SOLO LED on, A LED on.

2. Press [CAPT], then the [REF] (3) calculator key.

This captures the current time code value for the master
machine, then stores that value as the reference sync point.
A reference point for the master machine is a position on the
master tape to which slave tape sync points position.

3. Press [B] to Solo the slave machine.

4. Press [CAPT], then the [SYNCP] (4) calculator key.

Keyboard Control Unit
09/08/00 4-17

This captures the current time code value of the slave (B)
machine and stores it into the sync point register. The offset is
calculated automatically and stored in the Offset register.

5. Press the [RCL] key, then [OFST] (5), to verify the correct

offset. Use the [RCL] key if desired.

Getting Started

6. Press [SOLO], [A], then [>], to Solo the A machine in play

8. Press [STOP].

9. Press [SOLO], [B], then [>], to Solo the B machine in play
mode.

10. Press the [SRC SYNC] key.

This captures and stores a source sync point to the slave
machine Sync Point register.

11. Press [STOP].

12. Press the [GRP] key.

A LED on, B LED on, GRP LED on.

13. Press [ALLSTOP], then [STOP].

Trimming an Offset

The B machine chases and parks to the master machine
position.

14. Press [PLAY].

An offset can be trimmed by increasing or decreasing the frame or
subframe amount in any register. Default trim values are 1 frame
and 1 subframe.

Trim Frame: The value can be adjusted between 1 and 10 frames.
Trim Subframe The value can be adjusted between 1 and 25 subframes.

In the following example, assume that the A and B machines are
grouped. Although the tape machines are in stop in this example,
an offset can be trimmed dynamically with the tape machines in
play.

1. Press [GRP] + [STOP].

2. Press the [B] key.

Offsets in Differing Time Codes

The KCU handles offsets correctly in either drop frame or non­drop frame time code as well as in mixed time code situations.
Offsets are always stored and displayed in the code format of the
reference transport time code, regardless of the type of code that is
present on each source machine. For example, if the reference
time code is drop frame, all offsets are handled and displayed by
the KCU as drop frame time code values, even if a particular offset
is related to a machine with non-drop frame code.

and a calculator key to select a memory.

The time code value is stored to the In Point register.

Keyboard Control Unit
09/08/00 4-19

Getting Started

Drop frame code is displayed on the KCU with the frames digits
separated from the seconds digits by a semi-colon rather than a
colon, as in 03:20:40;00.

In mixed code situations, the actual offset value necessary to
achieve the desired synchronization in the KCU system is the sum
of the following three components:

• The actual (clock) difference between the two time code values.

• A correction to the clock offset based on the difference in frame

counts between the two time code formats.

• A correction for the accumulated frame count difference since

00:00:00:00 (time code ‘midnight’). This applies to drop
frame/non-drop frame time code only.

For example, if you want to synchronize 1:00:00:00 (non-drop
frame) with 1:00:00,00 (drop frame), an offset of 3 seconds and 18
frames is required to account for the difference in running frame
count since ‘midnight’.

The simplest method of calculating offsets is to use sync points or
capture the frame count and let the KCU calculate the correct
time code offset value.

Editing with the KCU

The KCU has comprehensive Rehearse, Record and Replay edit
routines. In and out points can be quickly marked with the
special function keys. The KCU cues all transports in the group to
the preroll point, executes an automated record at the in point,
and drops out of record at the out point.

Editing Example

For this example, A is the master reference machine and B is the
slave machine. Other machines may be added if desired.

1. Press the [>] PLAY key.

2. Press the [IN] key.

The group goes into play and locks.

4-20 09/08/00

JOG Key

NEXT Key

SHUTTLE Key

In jog mode, the wheel bumps a transport forward (clockwise) or
backward (counter-clockwise) a small amount each time that it is
turned. If you turn the wheel continuously, the tape scrubs past
the heads with a velocity proportional to how fast you turn the
wheel.

In setup mode, the [JOG] key is used as the [NEXT] key. This key
steps forward to the next item in a menu.

In shuttle mode, turn the wheel clockwise to move the selected
machines forward with a velocity proportional to the amount that
you rotate the wheel from its starting position. Turn the wheel
counter-clockwise to initiate variable-speed backward motion.
Shuttle speed may be varied from a slow crawl to several times
normal play speed.

ENTR Key

Shuttle mode is a controlled speed mode generally on video
transports only. Most audio tape machines do not have a variable
speed shuttle mode, so the shuttle function is implemented by
rapidly toggling between rewind and fast forward. The actual
velocity is determined by the ballistics of the particular machine.

Shuttle is used most effectively in solo mode to position a single
machine accurately for setting sync points and in and out points.
If you use shuttle in group mode, the wheel controls only the
master machine; all other machines will chase the master
machine and attempt to maintain their correct park-ahead offsets.

The [ENTR] key confirms operations that may cause a loss of data
or setup information. For example, [CLR] + [POLL] resets the
system only after you press [ENTR] to confirm this action.
