8.35. 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 ' S01BROADA: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
S01BROADA:B02PHONE1
Sends the command B02PHONE2
over the digital bus.
S01BROADA
B02PHONE1, this second status
message is from the EF2241 at
device ID 2 when it takes its phone
off hook.
8.36. 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.
The AEC reference is created in the main matrix via output R1.
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.
