User Manual
7.7.5. Port
Protocols like TCP or UDP use port numbers in the header to direct traffic around the
network. Low port numbers are used by computer systems for predefined tasks. For example
SMPT (for your email service) uses port 25.
A good rule is to use numbers above 10,000 to avoid conflict with existing services.
When you set up a port number on several computers on a network they will all listen for
packets directed to that port.
The default value is 10000.
7.7.6. Service Name
This text box lets you name the multicast stream as delivered in the SAP/SDP packets from
the unit. Default is MPEG Stream.
7.8. Configuration Tab – Data/IP Pane
The NETNode can send and receive data through either its RS232 serial port or its RS485
serial port. The switch between the RS232 port and the RS485 port is found under the
Global Settings tab.
7.8.1. Data Mode
The Data Port can be configured in three ways:
Off
UDP
TCP
7.8.1.1. Off
Data transfer is switched off.
7.8.1.2. UDP
UDP (User Datagram Protocol) is used to move data about the network. The packets are
sent out and the system does not expect a reply. There is no way that the sending device
can tell if the data arrived at the destination.
7.8.1.3. TCP
TCP (Transmission Control Protocol) is used to move data about the network. The packets
are sent out and the system will expect a reply. Each message is acknowledged by the
destination device.
7.8.2. Baud Rate
This is where you set the speed at which data will be transferred across the network. Speeds
available are: None, Illegal, 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200.
