Automixer Dependencies - Polycom Vortex EF2241 Programming Manual

Another thing to consider when using macros and presets is to use the
instead of the
MACROX
but the X versions produce acknowledgements for the settings that change, while the Q versions don't. If
your control system updates its status by looking at the acknowledgements that come back, then you'll
probably want to use the X versions. Another option would be to use the Q versions and then manually query
the values you're interested in. If your control system does not need use acknowledgements, or if you are
manually querying the values you're interested in, using the Q versions is better since it doesn't generate
acknowledgements and thus reduces RS-232 traffic.

3.5. Automixer Dependencies

The commands AMASGN, AMCHAIR, AMCHNUM, AMLMM, AMLMN, and
and can cause errors (ERROR#040 through ERROR#045) if an assignment attempts to break one of these
dependencies. See the descriptions of the above commands and the
on these dependencies.
The dependencies in these commands can cause a problem when trying to build macros. For example, your
macro may use the above commands to set the automixer to a certain configuration. The problem is that
although your commands would put the automixer in a valid configuration, one of the intermediate
configurations might be invalid. If this happens, the invalid command(s) will not execute and the automixer
will not be in the configuration that you intended.
For example, assume that we start with all inputs assigned to automixer group "none" (AMASGN), chairman
mode (AMCHAIR) is disabled for both automixers, chairman mic (AMCHNUM) is set to 1 for both automixers,
last mic mode (AMLMM) is set to off for both automixers, and last mic number (AMLMN) is set to 1 for both
automixers. Now, suppose your macro executes the following commands in the order shown.
AMASGN*ààåå
(assign inputs 1-2 to automixer 1 and inputs 3-4 to automixer 2)
AMCHAIR11
AMCHAIR21
AMCHNUM11
AMCHNUM23
AMLMM11
AMLMM21
AMLMN23
In this case, the AMCHAIR21 command and the AMLMM21 would not get executed. They would produce
ERROR#044 and ERROR#042, respectively. The AMCHAIR21 command causes an error because we try to
turn on chairman mode for automixer 2, but automixer 2's chairman mic is set to 1, whic belongs to
automixer 1. Similarly, the AMLMM21 command causes an error because we try to set last mic on mode to
manual for automixer 2, but automixer 2's last mic number is set to 1, which belongs to automixer 1.
There are many other ways that these dependencies can cause problems. Fortunately, there is a way to
avoid them. In you command sequences and macros, follow the following sequence when dealing with the
automixer paramters.
turn off chairman mode (AMCHAIR) for both automixers
