REGISTRATION
When controlling the system through a TCP connection the TCP client may “register” to receive status from
individual services. Registration is performed by sending a “#REGISTER” ASCII command to the StreamNet
device acting as the TCP server. This registration will time out after 30 seconds unless it is renewed by sending
another “#REGISTER” command.
A TCP client of a StreamNet device may “register” to receive status from a specific service. When a TCP
client such as a Flash application sends the “#REGISTER serviceName” command to the root service of the
device to which it is connected that device will start forwarding the status of the specified service to the TCP
client. This function is useful for controllers which cannot use multicast UDP. Adobe Flash can only make TCP
connections.
STREAmNET mULTICAST ADDRESSES
For each StreamNet system there is a single multicast address used by all of the devices for device discovery,
ASCII message routing, time synchronization, and other system level tasks; this multicast address is called the
“StreamNet System Multicast Address” and is configured into the device by the StreamNet set up program.
All other multicast addresses are assigned dynamically at run time by the StreamNet system master device.
The assigned addresses are chosen from a range of addresses configured into the device by the StreamNet
set up program.
These dynamically assigned multicast addresses would not normally be needed by any third party controllers
or other non-StreamNet devices; however, the addresses may sometimes be available through #qUERy
requests or other status reports.
IP ADDRESS ASSIGNmENT
Each StreamNet device must have an IP address. The device may obtain this address in any of several ways:
Static IP, Auto IP or DHCP. The installer may choose a preferred method of IP address assignment but if the
preferred method fails, the device may try other methods until an address is obtained. By default the devices
will initially try to obtain an address from a DHCP server. If after several minutes an address is not received
from a DHCP server, the device will attempt to obtain an address through the Auto-IP method. With the Static
IP method, the device will assume that the assigned address is valid.
NOTE: f If the device is configured for DHCP and no DHCP server is present on the system,
the device will remain unresponsive for several minutes until the Auto IP address is resolved.
