Serial Device Servers

UDP mode supports up to 4 multicasting groups

In UDP mode, the attached device can exchange data simultaneously with up to 4

network destinations, and at a higher speed than with TCP communication. This

mode is ideal for message display applications.

In Real COM mode, the serial port is assigned an IP:Port address and is mapped by

special drivers to a host computer's local COM or TTY port. Legacy applications can

then access the attached device using the local COM or TTY port without dealing

with network protocols.

TCP Server mode supports up to 4 connection requests

In TCP Server mode, the serial port is assigned a unique IP:Port address on

the TCP/IP network. The NPort simply waits passively for a host computer to

establish a connection with the attached device. TCP Server mode supports up to 4

simultaneous connections, so multiple hosts can collect data from the same serial

device at the same time.

TCP Client mode connects up to 4 hosts at the same time

In TCP Client mode, the NPort establishes a TCP connection between the attached

device and a specified host computer when data is received from the attached

device. After the data has been transferred, the NPort automatically closes the

connection.

How the NPort Provides Network Access to Serial Devices

Socket Mode—TCP Server Mode

Driver Mode—Real COM Mode

Socket Mode—TCP Client Mode

Socket Mode—UDP Mode

In RFC2217 mode, the serial port is assigned an IP:Port address

and is mapped to a virtual COM port by RFC2217-compliant

drivers. The RFC2217 protocol defines general COM port control

Driver Mode—RFC2217 Mode

options based on the Telnet protocol. The NPort supports any 3rd

party driver that is RFC2217 compliant.
