• field, and then press “update” button to continue. TFTP: • Use Windows Command Prompt window to run the tftp client program. • Syntax: tftp -i 10.1.1.1 put FILE_DIRECTORY\FILENAME.bin • The firmware update should take about 45 seconds to complete. • If the update process somehow goes wrong (like power failure), please connect to http://10.1.1.1 to try and restart the process (you may have to reset the device first).
TCP Mode Screen 3. The following settings can be configured: • Telnet Server/Client: Set the device to be a Telnet Server. In server mode, the Telnet port listens and waits for a host or other client to make a connection. In this case the Ethernet connected device is the client. • Reverse Telnet: Reverse Telnet works the same as Telnet Server mode. The Telnet port is listens for a connection after booting up.
4. 5. Note: CLI mode is only available when NETRS2321P is in TCP Server Mode. • Port Number: This assigns the TCP server port number that the server will listen on for connecting clients (Only for TCP Server Mode). • Remote Server IP Address: When in Client mode, this device will automatically try to connect to the remote TCP server with this IP address.
UDP Mode Screen 3. The following settings can be configured: • Mode: • Disabled: When UDP mode is enabled, TCP mode will be disabled automatically. In UDP mode, the Local Port will be assigned to this device. You can list the remote connection IP and Port for up to 10 remote devices. • Listen: When in UDP Listen mode, it can only receive remote UDP data. • Normal: When in UDP Normal mode, it can both receive and send UDP data to remote units. • Local Port: Assign the UDP port that this unit listens on.
Remote Address: The remote address table allows users to set several remote site IP addresses and ports. When sending data, the device will send UDP data to the IP addresses in the table. Once you have completed making changes, press the Update button to store the data. • 4. 5. Reset the device for the changes to take effect. UART UART or Universal Asynchronous Receiver Transmitter refers to the RS-232 serial port of the device. All of the port settings can be modified from the UDP screen. 1.
UART Screen 3. The following settings can be configured: • Baud Rate: Set the baud rate of UART interface. The NETRS2321P supports 110, 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 and 230400bps baud rates. • Character Bits: Set the number of data length of UART interface. The NETRS2321P supports character bits of 5, 6, 7, or 8 bits. To view manuals, videos, drivers, downloads, technical drawings, and more visit www.startech.
Parity Type: Set the parity of UART interface. The NETRS2321P supports parity settings of Odd, Even, Space, Mark or none. • Stop Bit: Set the stop bit length of UART interface. The NETRS2321P supports 1, 1.5 or 2 stop bits. • Hardware Flow Control: Set the flow control mode of UART interface as enabled or as none. • UART Memory Overflow Count: Shows the number of overflow bytes in network buffer. • UART FIFO Overflow Count: Shows the number of overflows counted in the UART RX buffer.

TCP/UDP Settings Depending on the protocol you are using, the options below will enable/disable automatically as applicable. Server/Client (TCP Mode Only) • Set the device to be a Telnet Server. In server mode, the Telnet port listens and waits for a host or other client to make a connection. In this case the Ethernet connected device is the client. • Set the device to be a Telnet Client. In the case the Ethernet connected device is the Telnet server or other NETRS2321P in server mode.
Remote Port • TCP Server – Disabled • TCP Client – Assign the remote TCP port you wish to communicate on. • UDP – Assign the remote UDP port you wish to communicate on Enable Control Connection (TCP Server or Client Only) • Enables/Disables control of the serial device on a remote network. Using the IP address and port number allows the user to gain control of the receiver from a remote location when this is enabled.
