16.7 Sequence Programming
Programming a Simple Camera Sequence
The Allegiant system has powerful sequencing capabilities. Using a system key- board, it is possible to enter sequences to run on a single or on multiple monitors. As long as valid camera and monitor numbers are used, they can be entered into a sequence randomly. More powerful features are available when sequences are pro- grammed via the
Sequence programming is limited only by the amount of CPU memory reserved for storing the sequence steps.
The current limit for this Allegiant model is 3000 steps. Comparing a sequence to a spreadsheet, a simple sequence would consist of three (3) columns as follows:
CAMERA | MONITOR | DWELL |
1 | 1 | 2 |
2 | 1 | 2 |
3 | 1 | 2 |
4 | 1 | 2 |
5 | 1 | 2 |
Sequence programming is best described by going through the above example. To enter the programming mode, press Program Sequence [Prog]. Enter an available sequence number (1 to 60 for this Allegiant model), then press [Enter]. The on- screen monitor display changes to the following format:
1st Line = Camera(Ignore) S0001 L0001 Time(Ignore)
2nd Line = >C0001< M001 D02 Date(Ignore)
The top line of the display always indicates the current step being viewed in the S0001 section. The total length of the sequence is displayed in the L0001 section. When programming a new sequence, the camera number that was being viewed before entering the programming mode is automatically placed between the > < prompts, as in the example C0001 above. Now enter the 1st camera of the sequence into this position. If the camera number is correct, no action is necessary. If not, enter the desired camera number via the keypad and press [Enter].
Using the joystick, move RIGHT one step. The prompts will shift over to the moni- tor number shown in the example M001. The monitor that was being controlled by the keyboard before entering the programming mode is defaulted to this position. If correct, no action is necessary. If not, enter the desired monitor number via the key- pad, and press [Enter].
Move RIGHT again. The prompts now shift over to the dwell time shown in the example D02. The default dwell time for a new sequence is always two (2) seconds. If a different dwell period is desired, change the value to any number between 1 and
60.One line is now complete. Press Next Step [Next] to add a second line. The camera number increments automatically, while the monitor number and dwell remain the same as the first line. Since this line is correct, no change is necessary and Next Step [Next] may be pressed three (3) more times until line five (5) is reached. The joystick can be used to move around within the spreadsheet, but only the Next Step [Next] key can add new lines.
