Getting Started

When installed, the vNet Power over Ethernet (PoE) device becomes part of a data monitoring system comprised of several software components ( including viewLinc, Veriteq vLog or Spectrum), and hardware components (Veriteq data loggers, a PC with a supported Web browser, and the vNet device).

Before you start using your vNet device, complete the installation and configuration instructions included in this User Guide.

Once your vNet device is installed (connected to the data logger and your network), you are ready to complete the configuration steps detailed in this User Guide.

Installing the vNet device at your Site

There are a few things to remember when connecting your data logger to the vNet device:

• Remove the protective label on the bottom of the data logger.

• Be sure to slide the logger as far right as possible towa rds the two tabs before pushing down into the vNet device bed (you should hear a ‘click’). Refer to Figure 2, “Inserting data logger into vNet device” on page 3.

• If you are mounting the vNet device on a wall, ensure the device is in the upright position (the fan on top and data connections on the right).

• Use the wall anchors and screws prov ided for use with the vNet device mounting brackets.

Important: Do not drop the device as the impact may

damage it.

System Summary.

Note: This summary includes all the important informa-

tion about your vNet device, such as device name, contact person, current IP address, MAC address, model name, and firmware version.

Configuring IP Settings

There are three methods to assign an IP address to a Veriteq vNet device:

1 Configure a DHCP server to reserve a specific IP

address for the device (by MAC address) and automatically assign it to the device.

2 Manually assign a static IP address to the device. 3 Allow a DHCP server to automatically assign any

available IP address to the device.

Either of the first two methods is recommended. The V er iteq vNet device has DHCP enabled by default. If your network does not have a DHCP server, you will need to manually assign a static IP address.

The last method is not recommend ed be ca use the DHCP server could periodically assign a different IP address to the device. If this occurs, viewLinc and the other Veriteq sof tware will be unable to communicate with the data logger or the vNet device until Windows Device Manager is used to

To manually configure IP settings for your vNet devic e:

From the vNet Configuration and Management interface,

choose Configuration | Network | IP Settings.

2 Select the option Manually configure the IP Settings

using static value s, then enter the IP Address, Subnet

Mask, and Default Gateway supplied by your IT administrator.

3 Click Apply. 4 A message will appear stating that the vNet device

needs to be restarted. Click on the here

the device.

Creating a NetBIOS Name

A NetBIOS name provides an easy way to connect to your vNet device through a Web browser without having to remember the device’s IP address.

To access the device using the NETBIOS name, simply enter the name in the address line of your Web browser:

http://NetBIOSname

The factory default NetBIOS name is VERITEQXXXXXXXX (X denotes the 8-digit serial num ber of the vNet device).

To change the NetBIOS name:

From the vNet Configuration and Management interface,

choose Configuration | Network | IP Settings.

Page 19

2 In the NetBIOS name field you can enter up to 15

characters (using letters, numbers, and underscores). Do not assign the same name to another device.

3 Click Apply. 4 A message will appear stating that the vNet device

link to restart

Note: The speed setting is fixed at 10Mbit and cannot

be changed.

Editing Serial Port Settings

Use the Serial Port Settings screen to set the TCP port numbers that the vNet device will use for serial communication. The vNet device communicates with the V eriteq data logger through a serial port.

The serial port is accessed by the client PC using serial port redirector (virtual COM port) software that communicates over the Ethernet connection using TCP ports. The vNet device needs to be configured to use the same TCP port as the serial port redirector software.

vNet Power over Ethernet Device User Guide 15

Page 20

About Loopback Test Mode

The loopback test mode should only be enabled when doing diagnostic tests to solve problems with logger communication. The Loopback Test Mode checkbox must be unchecked to communicate with the connected data logger. Unchecked is the default setting.

When the loopback test mode is enabled, it enters a diagnostic mode where data received from the client PC is transmitted back to the PC, but not to the data logger. This can help to determine if a communication problem is due to the data logger, the vNet device, or the driver on the PC. A change to this setting only takes effect when the port is closed, then reopened. The checkbox is automatically cleared when the vNet device is restarted, or if more than 1 hour has elapsed since it was checked.

Using RealPort

The serial port on the vNet device can be accessed using the Digi RealPort protocol. If a RealPort driver is installed on a client PC, it can be configured to access the serial port using the RealPort TCP port number.

The factory default setting is 771. It is important to note that only one RealPort client can

connect to the vNet device at a time. The RealPort driver should only be installed using a Veriteq vNet Device Driver installation disk to ensure that the client PC will only connect to the vNet device when trying to open the serial port. When the serial port is closed, the TCP connection is also closed, allowing another client PC to connect to the vNet device.

If the driver is installed from a Digi Software & Documentation CD, the RealPort driver on one client PC will connect to the vNet device when the PC starts and keep the TCP connection open. No other PC will have access to the vNet device.

If needed, there is a setting in the RealPort dr iver that can b e changed to permit access from multiple computers ( see page

17).

Page 21

Using Raw TCP

The serial port on the vNet device can also be accessed using generic third-party Ethernet-to-serial port redirector software. These applications can send and receive data using the Raw TCP port number.

The factory default setting is 9761. When using the serial port in Raw mode, the client PC can

only send and receive data. There is no access to ser ial port settings such as baud rate or control lines (the serial port is automatically set to 19200 bps, 8 data bits, no parity bit, one stop bit).

To set the Serial Port settings for your vNet device:

From the vNet Configuration and Management inter face,

choose Configuration | Network | Serial Port Settings.

2 Enter new port numbers. 3 Click Apply. 4 A message will appear stating that the vNet device

Network Statistics Table

Use the Network Statistics table to monitor the network activity:

• Accepted Rx Packets: The number of receive d Eth er net packets that were accepted for further processing.

• Rejected Rx Packets: The number of receive d Eth erne t packets that were rejected for various reasons, such as protocol not supported, multicast address not supported, or packet errors.

• Rx Overrun Errors: The number of times a receive overrun was detected, i.e., one or more packets were dropped because the receive buffer was already full with previously received packets that had not yet been processed.

• Transmitted Pa ckets: The numbe r of Ethernet packets that were transmitted by the device.

• Stale Connections: The number of times a TCP connection for RealPort or Raw TCP was closed because it was “stale” or “half-open”.

• Last Restart Date: The date/time when the device was last restarted.

Note: Restarting the device will reset these five net-

work statistics counters (packets, connections, errors) to 0 and update the last restart date.

Backing Up or Restoring Configuration Settings

We recommend you save your current vNet device configuration settings to a backup file so they can be restored at a later time. You can also use this backup file to configure another vNet device.

When restoring settings from a configuration backup file that was created by a different vNet device, consider the following:

• The configuration backup file is a plain text file that can be edited.

• You can remove items from the con figuration backup file if you do not want to change their settings (such as NetBIOS name).

Page 29

• There are vNet device-specific items in the configuration backup file that are for informational purposes only and do not get applied when the file is restored (such as serial number, MAC address, model name and description).

Item Configuration

UseDhcp When UseDhcp = true, DHCP is enabled and the vNet

device will try to automatically acquire IP settings. When UseDhcp = false, the vNet device will use the user defined IP address, Subnet mask and Gateway items in the configuration file.

IpAddr The IP address that will be used if UseDhcp = false

SubnetMask

GatewayAddr

NetBiosName

The Subnet mask that will be used if UseDhcp = false.

The Gateway address that will be used if UseDhcp = false.

The NetBIOS name that can be used to access the device. It must be 1 to 15 characters long. You can use any alphanumeric combination and the underscore character ( _ ).

EthDuplex The Ethernet mode that the device will use on the

network to which it will be installed. Valid duplex values are Half or Full.

CloseTimeout

The control setting to enable or disable the web interface idle timeout. Valid values are true or false.

IdleTimeout The timeout value in minutes (1 to 120) that will be

used if the CloseTimeout = true.

HttpPort The TCP port number that the vNet device will use to

display the web interface.

Updating the vNet Device

You many need to update the vNet device application software if a problem has been identified or if new features are available. You can update the applica tion firmware, the boot loader, or the Web interface.

Important: Only update the vNet device when instructed

to do so by a Veriteq representative, and ensure the update is complete before unplugging any cables.

Important: Communication with the data logger attached

to the vNet device will be disrupted during the update.

To update the vNet devi ce :

From the vNet Configuration and Management interface,

choose Utilities | Update Firmware.

2 In the Update screen, from the drop-down list, select

Boot Loader, Firmware or Web Interfa ce.

3 Click Browse to locate and select the update file

provided by a Veriteq representative, then click Open.

4 Click Apply. Updating the boot loader or firmware will

take about 1 minute to complete. The vNet device will restart automatically, and the web interface will reload. It will take about 1 minute for a web interface update to complete and the new web interface to load.

Restarting the vNet Device

Sometimes it is necessary to restart the vNet device for new configuration settings to take ef fect. If restar ting is necessary, you will be prompted to restart by using the link appearing at the top of your Web browser.

The restart process takes approximately 15 seconds to complete. During this time the vNet device is unavailable.

Page 33

The vNet Configuration and Management interface takes about 1 minute to reload after restarting .

Important: Restarting the vNet device will disconnect all

connected clients and close their sessions. Closing a connection to a client disrupts communication between the client and the data logger that is attached to the vNet device.

You can restart the vNet device from the vNet Configuration and Management interface or from the vNet device itself.

To restart the vNet device using the Web interface:

From the vNet Configuration and Management inter face,

choose Utilities | Restart Device.

2 From the Restart Device screen, click Restart. 3 At the Restart prompt, click Yes.

To manually restart the vNet device:

On the vNet device itself, press and immediately rele ase the restart button. (Refer to Figure 4, “Restart button on vNet device”.)

Important: Do not press the restart button for more than

one (1) second, or you might restore all settings to their factory default values.

Restoring Factory Default Settings

You may need to restore the vNet device configuration to factory default settings if:

• you forgot the administrato r passwor d

• you changed the TCP port for HTTP but don’t remember what it is

• you want to remove all custom configuration changes

Before restoring factory default settings, you must choose whether or not you want to keep the IP settings and administrator password you have already set (recommended).

Important: If you do not check the option to keep the

current IP settings, DHCP is automatically enabled. This could result in the vNet device acquiring a new IP address if it had previously been configured with a static IP address. If this happens, you will need to rediscover the vNet device using the Digi Device Discovery software (Start | Digi | Digi Device Discovery).

You can restore default settings on the vNet device using the web interface or from the vNet device itself using the restart button.

To restore factory default settings using the Web interface:

From the vNet Configuration and Management interface,

choose Utilities | Factory Default Settings.

2 To keep the IP address settings and administrator

password but reset all other settings to the factory defaults, select the option Keep IP Settings and

Administrator Password.

3 If you do not want to keep IP address settings, clear the

checkbox.

Page 35

Note: If you do not keep IP address settings and pass-

word, the IP settings will revert to DHCP, and the administrator password will revert to ‘dbps’.

Click Apply.

Restoring factory default settings will take about 45 seconds to complete. The vNet devicewill restart automatically and the web interface will reload.

To manually restore factory default settings :

On the vNet device itself, press and hold the restart button for at least five (5) seconds. (Refer to Figure 4, “Restart button on vNet device,” on page 29). There is no warning before the factory default settings are restored.
