8.32. BROADA -- Broadcast Commands to Other Connected
Devices
This command is used to broadcast commands to other connected Polycom devices via the EF Bus and/or ASPI
Bus. For example, the command 'F01BROADA:B02PHONE1 ' would cause device ID 1 to send a command to the
EF2241 at device ID 2 to tell it to take its phone off-hook. The EF2241 at device ID 2 would respond by taking its
device off-hook and sending an acknowledgement.
This command is usually used in macros when one needs to have a macro on one device trigger an action on
another device.
Example Description Status Message
F01BROADA:B02PHONE1
Sends the command B02PHONE2 over
the digital bus.
F01BROADA
B02PHONE1, this second status message
is from the EF2241 at device ID 2 when it
takes its phone off hook.
8.33. BUSREF -- Set Which AEC Reference is Placed on EF Bus
This command sets or queries whic AEC reference (if any) is placed on the EF Bus. Setting BUSREF to '0' means
that no reference is placed on the EF Bus. Setting BUSREF to '1' means that AEC reference 1 (R1) is placed on
the bus. Setting BUSREF to '2' means that AEC reference 2 (R2) is placed on the bus.
The AEC references are created in the main matrix via outputs R1 and R2.
Only one Vortex can put a reference on the EF Bus at a time. If more than one Vortex places its reference on the
EF Bus, then an 'ERROR#093' will occur.
This command is an integer command. See
Section 6.2 for more information on this type of command. The
minimum and maximum values for this command are 0 and 2, respectively.
This command is saved to non-volatile memory only as part of a preset. The state of this command will be
restored after power-up only if a preset is saved and that preset is set to be the power-on preset.
Example Description Status Message
