Introduction Packaging Contents • 1 x Serial over IP Device Server • 1 x Universal Power Adapter (NA/UK/EU) • 1 x Software CD • 1 x Instruction Manual • 1 x DIN Rail Kit Installation Web Browser Method 1. Plug in the power adapter and connect the RJ45 interface to your LAN. NOTE: Alternatively, you can also use a crossover cable to connect the NETRS2321P directly to your system for the initial configuration. 2.
Broadcast Search The Broadcast Search function is used to locate all NETRS2321P devices that are connected to the same LAN as your computer. Since the Broadcast Search function searches by MAC address and not IP address, all NETRS2321P connected to the LAN will be located, regardless of whether or not they are part of the same subnet as the host. NOTE: Broadcast packet packets are not passed through a router. The VCom utility can only be used to monitor devices in the same segment of the LAN.
Web Console Operation Enter the IP address you have set for the NETRS2321P device into your web browser address bar (default IP: 10.1.1.1) and you will prompted to login with your user ID and password (Default: admin/admin). After a successful login, you will see Administrator, TCP Mode, UDP Mode, UART, and Reset Device selections in left frame of the web console - the following sections will describe their function.
System IP On this page, you can adjust the NETRS2321P network configuration. If set to DHCP mode, all other settings will be ignored, and the IP address will be assigned by DHCP server after resetting the device. Press “Update” to store the data. Reset the device to take effect. System Status On this page, you can display the system Kernel firmware version and MAC Address. You can also adjust the device alias (Target Name) and Idle timeout settings.
Load default setting On this page, you can load and store the factory default settings into EEPROM. NOTE: Network settings and MAC address will not be changed. Press “Load” to load default settings. Reset the device to take effect. Firmware update On this page, you can update the firmware via Ethernet. WARNING! Pressing the ‘Load’ button will immediately erase the flash with no further warning 1. Pressing the “Load” button will erase flash. 2. Wait for erase process to complete. 3.
TCP Mode NOTE: When TCP mode is set to Server or Client mode, the UDP mode will be disabled automatically. When UDP mode is enabled, the TCP mode will be disabled automatically. Once you have completed making changes, press "Update" to store the data. Reset the device to take effect. 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. If you encounter errors when using some Telnet clients, such as the Microsoft interpretation of Telnet for Windows XP you can try the connection using Reverse Telnet mode. CLI Mode The Command Line Interface (CLI) allows user to configure and control NETRS2321P directly through the UART interface. NOTE: CLI mode is only available when NETRS2321P is in TCP Server Mode.
UDP Mode 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. Once you have completed making changes, press "Update" to store the data. Reset the device to take effect. Mode 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.
UART UART or Universal Asynchronous Receiver Transmitter refers to the ‘RS-232 serial port’ of the NETRS2321P. All of the port settings are modified from this page. Once you have completed making changes, press "Update" to store the data. Reset the device to take effect. 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.
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. Delimiter This sets the Character 1 and/or Character 2 to be used as the delimiter. When sending data from serial to TCP the data is first stored in the cache.
Virtual COM Software Operation The Virtual Com application lets you install and configure your NETRS2321P easily over the network. Five function groups are provided to ease the installation process, allow COM mapping, and provide monitoring and IP location server functions. Configuration Once the software is installed and you have searched the device on your network (outlined in Installation section), all NETRS2321P devices on the LAN should appear in the list of available devices.
COM Mapping To map a virtual COM port, select COM Mapping from the left pane of the VCOM application, then click Add Click OK to create the COM Mapping TCP/UDP 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.
