STARTECH NETRS2321P (01) PDF Document

To mount the STARTECH NETRS2321P using the DIN Rail method:

Attach the included DIN Rail brackets (one per side) using the provided screws to the top DIN Rail screw hole (marked on the device top view) and clip the unit to your DIN Rail.

To load the factory default settings:

Press and hold the Load Default/System Reset button for more than 3 seconds, then release it.

The default settings are as follows:

• IP address: 10.1.1.1
• Subnet Mask: 255.0.0.0
• Login ID / Password: admin

To reboot the device while maintaining configuration settings, press and hold the reset button for more than 10 seconds, then release it.

Note: This serial device server performs as a DTE device.

1. Plug in the power adapter and connect the RJ45 interface to your LAN. Alternatively, you can use a crossover cable to connect the device directly to your system for the initial configuration.
2. Press and hold the load default button for more than 3 seconds and less than 10 seconds, then release it. This will return the serial device server to factory default and it will respond to the IP address 10.1.1.1.
3. Configure the PC to the same IP domain.
4. Open a web browser and connect to http://10.1.1.1 to open the configuration interface. The default login ID will be “admin” and the password will be “admin”.
5. Once logged in, you will have access to all configuration settings including the ability to change the IP address for the device server.

1. Plug in the power adapter and connect the RJ45 interface to your LAN.
2. Insert the included CD and launch the VirtualCom software.
3. Follow the on-screen instructions to install VirtualCom and WinPcap.
4. Once installed, double-click the VCOM shortcut to launch the application.
5. Click the Search button in the VCOM software window to locate the device.

Note: You may receive a firewall notification at this point of the install, please allow access to this application.

The Broadcast Search function is used to locate all STARTECH 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 units 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.

In the web console, navigate to the Authentication page. Here you can change the login ID and Password. The STARTECH NETRS2321P device supports a maximum of 15 characters for the password, and only alphanumeric characters are allowed (“0-9”, “a-z”, “A-Z”).

Press “Update” to store the data. Reset the device to take effect.

On the System IP page of the web console, you can adjust the network configuration. If set to DHCP mode, all other settings will be ignored, and the IP address will be assigned by the DHCP server after resetting the device.

Press “Update” to store the data. Reset the device to take effect.

On the System Status page of the web console, you can display the system Kernel firmware version and MAC Address.

You can also adjust the device alias (Target Name) and Idle timeout settings. The Target Name field allows a Max of 12 characters, including “0-9”, “a-z”, “A-Z”, “_” (underscore), and “-” (dash).

Press “Update” to store the ‘Target Name’ data, and then, the device will reset to take effect.

WARNING! Pressing the ‘Load’ button on the firmware update page will immediately erase the flash with no further warning.

Procedure:

1. Press the “Load” button to erase flash.
2. Wait for the erase process to complete.

There are two methods to do the Firmware Update action (TFTP or Web):

Web Method:

Please type in or browse the target image file in the input field, and then press the “update” button to continue.

TFTP Method:

1. Use the Windows Command Prompt window to run the tftp client program.
2. Syntax: tftp -i 10.1.1.1 put FILE_DIRECTORY\FILENAME.bin
3. The firmware update should take about 45 seconds to complete.
4. If the update process fails, connect to http://10.1.1.1 to try and restart the process (you may have to reset the device first).

Note: Please avoid loss of network connection, power, or other interruption during the firmware upgrade procedure.

To configure TCP Mode, access the TCP Mode section in the web console.

Telnet Server: 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.

Telnet Client: Set the device to be a Telnet Client. In this case, the Ethernet connected device is the Telnet server or another STARTECH NETRS2321P in server mode.

Note: When TCP mode is set to Server or Client mode, the UDP mode will be disabled automatically. Once changes are made, press “Update” to store data and reset the device to take effect.

Reverse Telnet: This works the same as Telnet Server mode. The Telnet port 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 the user to configure and control the STARTECH NETRS2321P directly through the UART interface. Note: CLI mode is only available when the device is in TCP Server Mode.

When UDP mode is enabled via the web console, TCP mode is disabled automatically.

Mode Options:

• 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.

Settings:

• 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 (up to 10 remote devices).

UART settings modify the RS-232 serial port configuration. Access the UART page in the web console to adjust the following:

• Baud rate: Supports 110, 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, and 230400bps.
• Character Bits: Supports 5, 6, 7, or 8 bits.
• Parity Type: Supports Odd, Even, Space, Mark, or none.
• Stop Bit: Supports 1, 1.5, or 2 stop bits.
• Hardware Flow Control: Set to enabled or none.

Press “Update” to store data and reset the device to take effect.

Delimiter: This sets 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. When set, the data is not released from the cache and sent to TCP until the value of character 1 or 2 is received from the serial side.

Silent time: If there is no data sent or received for the number of milliseconds specified, the connection is dropped.

Drop Character: This option drops the delimiter character of the serial port when sending to TCP (the receiver doesn’t display the character).

To map a virtual COM port:

1. Open the VCOM application.
2. Select COM Mapping from the left pane.
3. Click Add.
4. Configure the settings (Device Name, IP Address, Local Port, COM number, Remote Port).
5. Click OK to create the COM Mapping.

If the equipment causes harmful interference to radio or television reception, try the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
