NPort 6000 Series Introducing Serial Port Operation Modes
UDP Mode
Compared to TCP communication, UDP is faster and more efficient. In UDP mode, you can unicast or
multi-unicast data from a serial device to one or multiple host computers; and the serial device can receive data
from one or multiple host computers. These traits make UDP mode especially suited for message display
applications.
Pair Connection and Secure Pair Connection
Modes
In Pair Connection mode, two NPort 6000 servers work together to remove the 15-meter distance limitation
imposed by the RS-232 interface. One server is arbitrarily designated the master and the other as the slave—it
does not matter which is which as long as there is one of each. One server is connected from its RS-232 port
to the COM port of a PC or another type of computer, such as a handheld PDA that has a serial port; the other
server is connected to the serial device through its RS-232 port.
The two servers are then connected to each other over the network.
