5.7 UDP Mode
The UDP mode is a faster and more efficient mode. In UDP mode, you can unicast or
multicast data from the serial device to one or multiple host computers, or receive
data from one or multiple host computers. The UDP mode is ideal for applications
such as message display.
In the figure, UDP mode directly proceeds with data transmission with no connection
required.
Under the “HOME” page of NCOM-113-M’s firmware, select “NETWORK SETTINGS”
to find the “Port 1 Mode Settings” window. Under “Mode”, select “UDP” and choose
“Use Unicast” or “Use Multicast” under “Multicast Setting”. When selecting “Use
Unicast”, you need to type a “Destination IP Address” (such as 192.168.1.147) to
establish a UDP connection with a pre-determined host computer or serial device in
UDP unicasting mode. When selecting “Use Multicast”, you need to type
“Multicasting IP Address” (such as 224.0.0.0) for UDP multicasting group. Check the
“Make these the default settings” box and click “Apply Changes” to set your NCOM-
113-M into UDP Mode.
