Multicast IP Addresses
Each 8186 SIP Horn Speaker has its own IP address, and shares a common multicast IP
and port number (multicast zone) for multicast packets. The master speaker transmits to a
configurable multicast zone, and the slave units listen to all the multicast zones assigned
to them.
The network switches and router see the packet and deliver it to all the members of the
group. The multicast IP and port number must be the same on all the master and slave
units of one group. The user may define multiple zones by picking different multicast IP
addresses and/or port numbers.
1. Multicast IP addresses range: 224.0.0.0/4 (from 224.0.0.0 to 239.255.255.255)
2. Port numbers range: 1 to 65535
3. By default, the 8186 SIP Horn Speaker is set to use the multicast IP address
224.0.2.60 and the port numbers 50000-50008
Make sure that the multicast IP address and port number do not conflict with other
services and devices on the same network.
Multicast Page Zones
The 8186 SIP Horn Speaker supports nine "basic" multicast zones. These zones are
defined by the multicast IP addresses.
Somewhat arbitrarily, these zones are defined below but may be used in other ways. The
important consideration is that there is a priority hierarchy – streaming activity on a zone
higher on the list, will be treated as a higher priority than a zone lower on the list – with
music being the lowest priority.
1. Priority
2. All Call
3. Zone 1
4. Zone 2
5. Zone 3
6. Zone 4
7. Zone 5
8. Zone 6
9. Music
"Expanded" zones can also be enabled, in the Basic Settings > Multicast tab, allowing
up to 50 zones in total. These have the same behaviors as the basic zones, but are
hidden by default to simplify the interface.
