5. Dwell Time

The dwell entry is the time, expressed in
seconds, that the selected camera is to appear
on the display monitor. For example, using the
above sample program, in step 1, camera 10 will
appear on monitor 4 for five seconds. The dwell
time may be from one to 60 seconds. If more
than a sixty second dwell time is required, simply
enter the same camera and monitor combination
in the following step along with an additional
dwell time. In addition to the numeric entry, the
user may choose three other options as a
sequence dwell entry - HOLD, UNLOAD, and
SALVO. SALVO will be explained later in the
section on the SalvoSwitching
cell prompts (">" "<") before and after the dwell
number.
The HOLD option allows the programmer to run
a sequence to a certain point and stop. This point
can be considered like a "home" location which
will be displayed unless the user takes a "tour"
with the run command. The sequencer will then
run until the next hold is encountered. To enter a
HOLD dwell, key in '62' as the dwell time. In the
example, cameras #10, 8, and 6 will sequence
on monitor #4, with each being displayed for 5
seconds. Cam #20 will be displayed for 3
seconds before switching to cam #1. Since step
5 contains a HOLD command in the dwell
column, Monitor #4 will display camera 1 until
the operator continues
depressing the RUN key on the keyboard.
The UNLOAD option allows the programmer to
run a sequence to a certain point, then
automatically unload the sequence from its
monitor. The sequence still remains stored in the
system memory.
command, key in '63' as the dwell time.
Sequence Programming Instructions
Note that a sequence may be any length as long as
the combined total of all sequences does not exceed
3000 steps.
In the program mode, the monitor display shows the
step number and sequence length, and cell prompts
appear in the camera identification display area.
1. Press PROGRAM and verify the indicator lights.
2. Key in the sequence number (1 through 60)
using the numeric keypad and press ENTER.
The video monitor display should change to a
default appearance as shown below:
023 S0001 L0001 12:01:01

3. Key in the number of the first camera to appear
in the sequence using the numeric keypad.

4. If the entry is correct, press ENTER or use the
joystick to move right. At this point, if the camera
is available to the user (i.e., the camera has not
been restricted in the lockout table), the system
will enter the camera into the sequence.
5. Verify the camera is correct. If the joystick was
moved right to 'enter' the camera, the display will
then appear as:
023 S0001 L0001 12:01:01
C0001>M001<D02 12-25-88
6. In this field, key in the number of the monitor on
which the camera should appear.
7. If the entry is correct, move the joystick right.
The video display should then look like this:
023 S0001 L0001 12:01:01
C0001 M001>D02< 12-25-88.
Key into the numeric keypad the duration in
seconds (1 to 60) that the above camera is to be
displayed on the selected monitor. In addition to
seconds, the user may enter 61 for 'salvo' mode,
62 for 'hold', or 63 for 'unload'. The 'salvo' mode
means go to the next step immediately (no
dwell), and 'hold' means stop the sequence on
this step. 'Unload' removes the sequence from
the active monitor workspace. If using the 'salvo'
mode, be sure to enter a dwell in seconds as the
last step of the 'salvo' switch. A 'salvo' entry
would change the display to look like this:
023 S0001 L0001 12:01:01
C0001 M001>SLV< 12-25-88

A 'hold' entry would look like this:
023 S0001 L0001 12:01:01
C0001 M001>HLD< 12-25-88
An 'unload' entry would look like this:
023 S001 L001
C0001 M001>ULD<12-25-88
9. If the entry is correct, press NEXT to proceed
to the next step. One full step line has now
been entered and the next step may be keyed in
just as the first. Note as in the first screen below
that the length and step numbers have been
incremented, the camera number is incremented
(if allowed by the lockout tables), and the monitor
number and dwell have been copied from the
previous line.

If a previously entered sequence were being
edited, the length cell would indicate the total
number of lines in the sequence. Also, the
joystick may be used to move within an existing
sequence to simplify editing.
