CAI Commands Instruction
This instruction is used to Allow or Block serial control commands on a CAI communications channel.
This can be useful for blocking undesired control by a client during parts of a presentation, especially
when more than one client is connected to the eCNA-10. This only blocks ‘control’ commands. Status
commands are always accepted.
CAI Commands: Ch1 Block Blocks serial control commands on CAI channel 1
CAI Commands: Ch1 Allow Allows serial control commands on CAI channel 1
CAI Commands: Ch2 Block Blocks serial control commands on CAI channel 2
CAI Commands: Ch2 Allow Allows serial control commands on CAI channel 2
CAI Commands: Ch3 Block Blocks serial control commands on CAI channel 3
CAI Commands: Ch3 Allow Allows serial control commands on CAI channel 3
Segment Instruction
This instruction can be used to identify the current part or segment of the presentation. The active
segment name is displayed on the local and web status screens. The segment names are defined in
the in Segment Names setup screen. The client can also request the active segment with the SEGIDX
and SEGTXT Status commands.
Segment Seg: m1 m2 dd:dd
m1 = User-defined Segment name
m2 = Tmr1 - Tmr15 (timer number)
dd:dd = 0:00 to 99:99 (minutes:seconds)
A general purpose timer can be used to delay the action of this instruction. If a timer is not selected
the ‘minutes’ and ‘seconds’ list boxes are disabled and no delay will occur.
Call Macro Instruction
This instruction can be used in a program (or a macro) to run a macro.
A general purpose timer can be used to delay the action of this instruction. If a timer is not selected
the ‘minutes’ and ‘seconds’ list boxes are disabled and no delay will occur.
Call Macro d m dd:dd
d = 1 to 50 (macro number)
m = Tmr1 - Tmr15 (timer number)
dd:dd = 0:00 to 99:99 (minutes:seconds)
This instruction can be used in a program to call a macro. Used this way, a macro could define a
program segment. For example, suppose the following macros were defined:
Macro 1: Previews Flat
Macro 2: Previews Scope
Macro 3: Feature Flat
Macro 4: Feature Scope
Macro 5: Credits
Macro 6: Intermission
Macro 7: Between Shows
Each macro is a group of instructions used to set up the auditorium (lights, sound, screen, etc.) for a
particular segment of the presentation. The macros are then used to construct a program. Using
macros in this way makes a program look much simpler. Macros can be used as building blocks for
any program.
