Fibre optic cabling provides numerous benefits over Ethernet cabling, with superior signal integrity

and no signal interference from high powered electronics. It also enables units to be spaced over

longer distances without the distance limitation of Ethernet cabling.

By default, port 1 is configured as the upstream port and ports 2, 3 and 4 as the downstream ports.

The difference between upstream and downstream ports is the orientation of the fibre that is used for

transmitting data and the fibre used for receiving data. This is illustrated in Figure 4: Fibre orientation

of Upstream and Downstream ports.

Figure 4: Fibre orientation of Upstream and Downstream ports

Due to the difference in the fibre orientation, MST composite cable and fibre optic cable can only be

connected between ports on NS50 devices marked with a tick in the matrix below.

Single- and Multi-Mode Cables

The NS50 is supplied from the factory with 1000BASE-LX single-mode SFP modules. Customers

wishing to interface to other cable standards, e.g. 100BASE-FX single or multi-mode, should contact

MST to arrange replacement of the appropriate SFP modules.

NOTE: If replacing the single-mode SFP modules with multi-mode modules, the single-

mode patch

lead between the SFP module and the MST Composite Cable connector on the inside

of the housing needs to be replaced with a multi-mode patch lead.

JB11 junction boxes can be connected inline between any two units in the chain to

supply power. There is no need to isolate NS50 units to a single power source.

IMPORTANT: If an SFP is changed, the device must be rebooted or reset to detect

the change.

1.3.2 Ethernet Ports

The NS50 has four external Ethernet ports, that enable connection to other networking devices.

The four Ethernet ports also provide IEEE 802.3af PoE (Power over Ethernet) injector functionality,

allowing a single cable to be used for data and power to network devices. Each Ethernet port's

functionality can be configured by the web browser interface, or by centralised configuration

management. For more information on configuring Ethernet ports, see Configuring the VLAN Port

Map on Page 79.

1.3.3 Wireless Access

Wireless connectivity in each NS50 is implemented using a WAC (Wireless Access Card), consisting

of a wireless network processor and an integrated mini PCI 802.11b/g adapter.

A NS50 can contain up to two WACs. The WAC contained in the first radio card slot (on the left side)

also acts as the management CPU for the switch processor. As such, it is mandatory that this WAC is

fitted to each unit. The WAC operational parameters can be configured through the web browser

interface or by centralised configuration management. For more information, see Configuring

Wireless Radio on page 63 and Editing Site Configuration Files on page 91.

Topics:

 Installation Types and Coverage

 Power Requirements

 Choosing Antennas

 Placement of NS50 Units

 Placement of Antennas

 Determining Distances between Wireless Network Switches

This chapter describes network system design for underground mines.

A MST System Engineer will usually design and preconfigure a network based on the requirements

and layout of each mine site. This will involve a visual inspection of the mine site to identify user

areas, and determine access point locations. A RF (Radio Frequency) site survey is also conducted

to understand the behaviour of radio waves in the mine. The following factors help determine network

design:

Wireless coverage requirements of the mine

 Quantity and type of wireless client devices connected to the network

 Wired client devices connected to the network and their location

 Interconnection to the mine's existing corporate network

 Policies for network protocol between networks

 Cabling requirements

 Antenna types to use with each unit and mounting method for each antenna

 Mounting location and installation method for each network device.

2.1 Installation Types and Coverage

Wireless network coverage can be described as:

 Wi-Fi hotspot — Network coverage is provided in key areas, such as crib areas and refuge bays.

 Full coverage — Seamless wireless coverage by strategically placing NS50 units so their radio

fields overlap.

A NS50 can communicate at wireless distances of 150-300 metres, depending on the geometry and

geology of the mine.

2.2 Power Requirements

The power requirements for a network are unique to each site installation. Determining power

requirements can be complex and is dependent on various factors such as the number of NS50 units,

PoE devices, branches in the network and composite cable lengths.

NOTE: A site inspection conducted by a MST System Engineer will help determine

the power requirements for your network.

The NS50 is designed to operate at a wide voltage range, from a minimum of 8VDC up to 54VDC.

Each NS50 in a network can internally step up the incoming voltage to 48VDC in order to supply

power to its connected PoE devices. The NS50 needs to receive a minimum input of 15VDC to power

PoE devices.

48VDC power supplies are used for large networks to maximise the distance between power

supplies. For smaller networks of 1-2 nodes, it is recommended that a lower voltage 24VDC power

supply is used.

External power supply recommendations:

- AC to DC power supply with galvanically isolated output(s).

- 48VDC output(s) (nominal)

- With 6A breaker / fusing in line with each 48V output.

2.3 Choosing Antennas

Antennas are connected to each NS50 to provide wireless network coverage. The type of wireless

coverage, surrounding geology, tunnel topology and stratum type are factors that will determine the

choice of antenna. A minimum of one antenna is required per WAC in a NS50.

Antennas consist of two directional patterns:

 Omnidirectional antennas — radiate equally in all directions for a short range, providing

immediate coverage in an open area.

 Directional antennas — radiate in a specific direction over a longer range. A higher gain antenna

will have a longer range and is more directional. It is important that directional antennas are

aligned properly between NS50 units to ensure continuous coverage between units.

The antenna radiation pattern and polarisation need to be considered to provide suitable wireless

coverage in an area.

Antennas commonly used with the NS50 are shown below.

Antenna Type

Illustration

Description

Omnidirectional 5.5dbi

rubber whips

A lower gain antenna that radiates equally in all

directions. It provides direct coverage in an open area.

Panel antenna

A panel antenna is a directional antenna, with a wide

horizontal beamwidth and narrower vertical

beamwidth. They are suited for covering an open area

in one direction.

Diversity panel antenna

A diversity panel antenna contains two panel antennas

in one housing with a 90° rotation between them. It

is used for providing better signal reception in difficult

areas, and more accurate AeroScout tag location when

Wi-Fi tracking is implemented. Diversity antennas

use both antenna connections on a WAC.

Yagi directional antenna

A Yagi antenna is high gain directional antenna. They

are ideally suited for line of sight tunnel

communications. Yagi antennas need to be aimed

accurately and avoid obstacles in their RF beam path.

2.4 Placement of NS50 Units

A site inspection will determine the best positioning of cables, NS50 units and antennas prior to

installation. NS50 units with antennas directly attached should be mounted in an elevated position,

within line-of-sight of mobile devices. Ideally this would be situated high up on a tunnel ceiling or on the

rock wall face. The mounting location should be free from debris, and avoid obstruction to vehicles,

equipment/machinery, vent tubing and cables.

NS50 units should not be installed in cut-out areas such as safety bays and remuck bays, due to

signal confinement. In such instances, a WAP is more suitable, connected to the nearest NS50. For

details on common NS50 mounting scenarios, see NS50 Mounting Options on page 15.

2.5 Placement of Antennas

Antennas are usually mounted separately from each NS50 to optimise transmission and avoid any

obstructions in a tunnel. They are connected by coaxial cable. The coaxial connection should be kept

as short as possible to minimise signal attenuation. Larger antennas / longer cable feeds can require

line amplifiers, and possibly bi-directional splitter / combiners for dual antenna systems.

Antenna placement is dependent on the surrounding geology, tunnel topology and stratum type. The

recommended placement of antennas is as follows:

Tip 1: Directionality

Antennas should be mounted and angled to give optimum transmission along curves and dips as

shown below in Figure 5: Angling antennas.

NS50 wireless network switch

User Manual

Revision C

Chapter 2: Network System Design

Commercial in Confidence

Figure 5: Angling antennas

Tip 2: Obstructions

Antennas should be mounted to avoid signal obstruction from rock, vehicles, equipment and

machinery as shown in Figure 6: Antenna mounting to avoid obstructions.

Figure 6: Antenna mounting to avoid obstructions Tip 3: RF Field Overlap

Multiple antennas should be mounted to avoid crossing signal paths as shown in Figure 7: Antenna

directivity.

Figure 7: Antenna directivity

The positioning of the antennas is crucial when AeroScout tags are used for asset tracking and

location services. AeroScout tags will not be read when there are antenna standing wave nulls.

Antennas need to be positioned to have best reception of tag messages. For Antenna mounting

options, see Antenna Mounting Options on page 15.

2.6 Determining Distance between Wireless Network Switches

Line of Sight Distances

In line of sight, each NS50 has a maximum wireless range of 300 metres (984 feet) using high gain

directional antennas. NS50 units are generally installed with a 100 metre (328 feet) overlap of the

radio field as shown in Figure 8: Wireless channel layout and distances Distances Around Curves

This ensures sufficient coverage between NS50 units.

NS50 units within range of each other must be configured with different Wi-Fi channels. By default

every fifth channel is used (channels 1, 6 and 11) to prevent signal overlap, minimising the possibility

of inter-modulation or interference.

Figure 8: Wireless channel layout and distances Distances Around Curves

The wireless range of a NS50 decreases when going around curves. In this case, NS50 units need to

be installed closer together to provide sufficient coverage. Distances between NS50 units will vary

depending on the drift and tightness of the curve. They are installed closer together on a tight curve.

Use the following steps to estimate the distance between NS50 units:

1. Install one NS50 unit at the beginning of the curve.

2. Install the second NS50 unit between 20 metres (65 feet) to 40 metres (130 feet) from the

end of the curve.

3. Install and align antennas.

4. Perform a RF signal strength test by walking from the first NS50 to the second NS50.

5. If the strength test records levels of:

3.4 Connecting Power to the NS50

A pre-deployment power-up test of NS50 units is recommended. To conduct a power-up test:

1. Connect the composite fibre/power cable to a DC power source with correct termination.

Note that the DC supply must be between 10 and 50VDC. Refer to the power supply

requirements Section 2.2.

2. Turn on the DC power supply and verify that the green power light is on. If there is no

green light, refer to Troubleshooting Guide on page 104.

Power can be applied to cabling whilst additional NS50 units are being installed. Power usage levels

should be evaluated prior to adding more units downstream to ensure that the voltage rail does not

drop too low. A minimum of 15VDC is required for a NS50 to supply PoE to other devices. If the

voltage drops below 15V, additional power is required.

3.5 Handling Composite Cable During Installation

The composite cable is ruggedly built for the mining environment. However the following

precautionary measures should be noted during installation:

 Never pull or create tension on the cable. Unreel the cable from the cable reel, or allow the weight

of the cable to unreel as the vehicle is moving as shown in Figure 13: Handling composite cable.

 Do not bend the cable at sharp angles; excessive bending can fracture or break the fibre optic

cable.

 Do not step on the cable.

Topics:

 Understanding Trunk and Access Ports

 VLANs and Wireless Networks

 Native VLAN

This chapter explains the principles behind a Virtual Local Area Network (VLAN). It is important to

understand VLANs to properly configure the wireless network switch.

A VLAN is a collection of nodes grouped according to their function or application, rather than their

physical location. They are grouped in order to separate and prioritise data within a network, as shown in

Figure 14: VLANs. VLANs are created when multiple applications, such as voice, telemetry, data and

video, are required in a mining network.

Figure 14: VLANs

NS50 wireless network switch

User Manual

Revision C

Chapter 4: Understanding VLANs

Commercial in Confidence

4.1 Understanding Trunk and Access Ports

VLANs can be assigned to trunk ports and access ports on a network. These two types of allocation

determine how data is transmitted and relayed.

4.1.1 Trunk Ports

Trunk ports typically provide a connection between network switches, and can carry data for multiple

VLANs. They will only transmit frames (packets of data) that belong to the port's assigned VLANs. To

identify the VLAN of each frame, a network switch adds a tag to the frame (known as 802.1Q trunking).

The tag contains the following information:

 VLAN ID — allows the network switch receiving a frame to identify the VLAN it belongs to.

 Priority ID — allows the network switch to prioritise distribution when multiple frames are being

transmitted. Priority ID ranges from 0-7, where 7 is the highest priority.

When a network switch receives a tagged frame, the tag is read to determine the VLAN it belongs to. The

tag is removed and distributed to devices connected on the same VLAN.

When the network switch receives multiple frames, it will prioritise the distribution of frames based on the

Priority ID in the VLAN ID tag. For more information on configuring VLANs, see Defining VLANs on page

77.

4.1.2 Access Ports

Access ports connect client devices such as PCs and laptops to the network switch, and can only be

assigned to a single VLAN. Access ports can only send and receive untagged frames, with those frames

allocated to the relevant VLAN inside the switch. Any tagged frames sent to an access port will be dropped.

An example of VLAN traffic flow through trunk and access ports is shown in Figure 15: VLAN traffic flow

and described below.

Revision C

Chapter 4: Understanding VLANs

Commercial in Confidence

Figure 15: VLAN traffic flow

1. A PC sends an untagged frame into access port 6 (Control VLAN) on wireless network

switch 1. The frame is sent to other access ports on the Control VLAN (access port 5).

2. Wireless network switch 1 tags the frame with VLAN ID = 4 and Priority = 5 and sends it

through the trunk ports to Wireless network switch 2.

3. Wireless network switch 2 receives the tagged frame, and identifies the frame belonging to the

Control VLAN.

4. Wireless network switch 2 removes the tag and sends the frame to all ports on the Control

VLAN (access ports 5 and 7).

5. If Wireless network switch 1 receives multiple frames, they are tagged and sent via trunk

ports to Wireless network switch 2.

6. Wireless network switch 2 receives the frames and prioritises distribution.

4.1.3 Port Allocation

Physical ports on the NS50 can be configured to be either a trunk port or access port using the web browser

interface or editing site configuration files when Trivial File Transfer Protocol (TFTP) is used. The NS50

default configuration has ports 1-8 allocated as trunk ports . Ports 1-4 are usually connected to other NS50

units, and ports 5-8 are connected to WAPs or other PoE devices. For more information on configuring

ports and VLAN membership, see Configuring the VLAN Port Map on page 79.

4.2 VLANs and Wireless Networks

The wireless network switch can have up to four wireless Service Set Identifiers (SSIDs) per

WAC. Each SSID is associated with a single VLAN and functions as an access port on that

VLAN. An example of a wireless network is shown in Figure 16: An example of VLAN and

wireless networks and described below.

Figure 16: An example of VLAN and wireless networks

1. An untagged frame is sent from a Laptop 1 through a wireless network (SSID = Data) on the

network switch.

2. The frame is tagged by the network switch and is sent through the trunk port to the WAP.

3. The WAP identifies the tagged frame as belonging to the Data VLAN and removes the tag.

4. The untagged frame is sent via the wireless network (SSID = Data) to Laptop 2.

Chapter 4: Understanding VLANs

Commercial in Confidence

4.3 Native VLAN

Trunk ports on the wireless network switch also support a Native VLAN. The Native VLAN is where

untagged frames will be allocated. On the network switch, the native VLAN is always the Infrastructure

VLAN. This allows client devices such as PCs or laptops to access and manage the network switch when

they are connected via a trunk port.

The Infrastructure VLAN is mandatory in the network switch and cannot be deleted.

An example of native VLAN functionality is illustrated in Figure 17: An example of native VLAN and

described below.

Figure 17: An example of native VLAN

1. The PC sends an untagged frame to Trunk port 3 on wireless network switch 1.

2. The frame is allocated to the Infrastructure VLAN.

3. The management CPU of wireless network switch 1 is always an Access port on the

Infrastructure VLAN and will receive the frame.

4. The untagged frame would also go to wireless network switch 2 via the Trunk ports between

the network switch units.

5. Wireless network switch 2 allocates the untagged frame to the Infrastructure VLAN.

6. The management CPU of wireless network switch 2 is always an Access port on the

Infrastructure VLAN and will receive the frame.

7. Any frame leaving the Management CPU is placed on the Infrastructure VLAN.

8. All frames on the Infrastructure VLAN are sent out untagged on Trunk ports.

Super AG Mode

Super AG is Atheros' proprietary frame-bursting, compression, and channel bonding technology to improve

Wi-Fi wireless LAN performance. This can dramatically improve the throughput of wireless traffic.

 Disabled – Standard 802.11g support, no enhanced capabilities.

 Super AG without Turbo – Default - Capable of Packet Bursting, FastFrames, Compression, and no

Turbo mode.

 Super AG with Dynamic Turbo – Channel 6 ONLY - Capable of Packet Bursting, FastFrames,

Compression, and Dynamic Turbo. This setting is backwards compatible with non-Turbo (legacy)

devices. Dynamic Turbo mode is only enabled when all devices on the wireless network are Super

AG with Dynamic Turbo enabled. In Turbo mode, the access point doubles the channel bandwidth to

increase the throughput.

 Super AG with Static Turbo – Channel 6 ONLY - Capable of Packet Bursting, FastFrames,

Compression, and Static Turbo. This setting is not backwards compatible with non-Turbo (legacy)

devices. Static turbo mode is always on and is only enabled when all devices on the wireless network

are Super AG with Static Turbo enabled.

Channels

It is recommended that WACs in proximity of each other have different wireless channels (for example,

Chapter 6: Centralised Configuration Management

Topics:

 Devise Management Overview

 TFTP Server Overview

 TFTP Parameters

Centralised configuration management is an alternative configuration method to the web interface. It

uses Trivial File Transfer Protocol (TFTP) where devices read and apply configuration files from a TFTP

server. It is a faster way to configure a large number of network switches, reducing the potential for

human error.

There are two ways to take advantage of TFTP configuration:

ICA v1.4.0 or later - Device Management via the ICA Administration Console

For networks with an ICA v1.4.0 or higher, AP settings can be managed from the ICA Administration

console. A customisable Site Default template is included at installation, and further templates can be

copied from it and modified separately. Additionally, individual APs can have specific settings overridden

In this case, the ICA will push configuration changes to the APs, and no local setup is required.

ICA v1.3.1 or earlier, and 3rd party TFTP servers - Manually editing configuration files

For older ICA systems and other TFTP servers, configuration files are edited and uploaded manually, and

APs must be configured to periodically self-check and fetch new configuration files from the server when

available.

More information about individual parameters is included in the TFTP Parameters section on page 92.

6.1 Device Management Overview

The ICA Administration Console (v1.4.0 and later) supports the creation of Access Point configuration

templates. A Site Default template is created at installation and applied to all managed devices. New

templates can be copied from the Site Default and applied to selected devices, and further overrides

can also be applied to individual devices.

Some familiarity with the ICA Administration Console is assumed here. For more information, see the

ICA Administration Console User Manual available from MST.

There are three editors in the ICA Administration Console with relevant settings:

 Configuration > Site Configuration

 Configuration > AP Config Templates

 Devices > Access Points

6.1.1 Site Configuration

This editor contains the option to Set new Access Points as Managed - If checked, all newly discovered

Access Points will be confgured according to the Site Default template by the ICA. If disabled, new APs

must either have their management settings configured in the Devices > Access Points editor, or be

configured manually.

6.1.2 AP Config Templates

The ICA is installed with one AP Template: Site Defaults. This is a special AP Template which defines

the settings that new APs will automatically pick up if Set new Access Points as Managed is ticked in

the Site Configuration editor. This template cannot be deleted, but new templates can be copied from it

and modified separately.

NOTE: Once a template is applied to an AP, any manual changes made to settings

listed in the template will be reverted automatically to the template default. Settings

that are not defined by the template can be changed freely.

New templates are created by copying an existing template (initially the only one to copy is Site Defaults).

A copied template will start with the same parameters as the original, but they are not linked, so further

changes to one will not affect the other. To create a new template, select another template from the list

and click the Copy button. To delete a template, click the Remove button.

AP Config Template Details

This section contains the details for each template:

 System ID is an automatically assigned identifier used by the ICA.

 Name - A name or description for the template.

6.2 TFTP Server Overview

Centralised configuration management using ICA v1.3.1 or earlier, or a 3rd party TFTP server, involves

the following steps:

1. Configure a TFTP server on the network. The ICA is preconfigured for this purpose.

Configuring a 3rd party server is outside of the scope of this document.

2. Define a site configuration file which contain global settings to all network devices on the site.

3. Define device configuration files which contain specific settings for each device, which override

global settings.

NS50 wireless network switch

User Manual

Revision C

Chapter 5: Configuration Using the Web Interface

Commercial in Confidence

4. Apply the configuration files to each device and reboot.

Network devices read and apply the configuration files from the TFTP server as shown below.

Figure 39: Centralised configuration management

6.2.1 Editing Site Configuration Files

Site configuration files contain common settings for all devices in a network. The site configuration file

has the naming convention ap_site_settings.conf. This file is retrieved by devices using TFTP.

NOTE: The same site configuration file can be used to configure network switch

units and WAPs in a network. When the site configuration file is applied to WAPs, all

switch port settings are ignored by the WAP.

The site configuration file can be opened on a PC and edited using a text editor. Parameters are

changed by modifying the text and saving the file. A description of the editable parameters are covered

in the following sections.

NS50 wireless network switch

User Manual

Revision C

Chapter 5: Configuration Using the Web Interface

Commercial in Confidence

To edit a site configuration file:

1. Open a text file editor on your PC.

2. Locate and open the site configuration file ap_site_settings.conf. This is usually stored in

the file directory folder of the TFTP server.

Edit the parameters as required.

Save the site configuration file in the directory folder of the TFTP server.

6.2.2 Editing Device Configuration Files

Device configuration files contain settings specific to each WAC in the network device. A device

configuration file is created for each WAC. Device configuration files follow the naming convention

ap_MACaddress.conf where MACaddress is the MAC address of the WAC. A device will recognise

and apply the device configuration file based on a comparison of the MAC address in the file name.

Note that any parameter from the site configuration file can override parameters in a device configuration

file. However, it is recommended that only the settings that are different be entered into the device

configuration file in order to make maintenance easier.

A device configuration file configures individual settings for each device as shown below. The device

configuration file can be edited using a text editor such as Wordpad or Notepad. The example below

includes settings that are commonly over-ridden. All other settings are inherited from the global site

configuration file. Comments are prefixed with a hash symbol (#) and are ignored by the device. These

are not necessary for configuration but may be included for convenience.

browser interface.

There is a network access

issue.

Check that the NS50 is properly installed, LAN

connections are connected properly and the unit is

powered on. If the PC uses a fixed (static) IP

address, check that it is using an IP address within

the IP range of the network switch.

Check that the VLAN settings on the devices

upstream on the network are not restricting access.

Power supply

instability.

Incorrect earthing scheme.

Check antennas are insulated from ground.

Check PCB in the network switch has a floating

earth (not grounded).

There are too many network

Appendix B: Composite Cable Testing

This appendix describes fibre optic cable continuity and testing. Fibre optic cable testing includes visual

inspection and power loss testing.

B1: Visual Inspection of the Fibre Optic Cable

Fibre optic cable can be inspected by visually tracing and inspecting the connector.

Visual Tracing

Checking for continuity diagnoses whether the fibre optic cable is damaged or broken. A visible light

"fibre optic tracer" or "pocket visual fault locator" connected to a fibre optic connector.

Attach a fibre optic cable to the visual tracer and look at the other end to see if light is transmitting

through the fibre.

If there is no light, there is a damaged or broken section of the fibre in the composite cable.

Visual Connector Inspection

A visual inspection of the fibre optic termination is usually carried out using a fibre optic microscope. It is

important the fibre termination has a clean, smooth, polished, and scratch free finish. Any signs of

cracks, chips or dirt will affect connectivity.

B2: Measuring and Testing for Power Loss

Measuring power and loss requires a Optical Time-Domain Reflectometer (OTDR) with a suitable adapter

matching the fibre optic connector being tested.

To measure power in fibre optic cable:

1. Set the OTDR to ‘dBm’ and set the wavelengths according to the fibre optic cable being

tested.

2. Attach the OTDR to the fibre optic cable at the receiving end to measure the output.

3. Compare the output with a reference test cable.

To measure power loss in fibre optic cable:

1. Set the power meter to ‘dB’ for a relative power range and select the wavelength required for

the test.

2. Perform a single-ended loss test by connecting the cable to be tested to the reference cable and

measuring power loss at the receiving end.

3. Perform a double-ended loss test by attaching the cable between two reference cables that

are attached to the source and to the OTDR. If high losses are measured, reverse the cable

and test in the opposite direction using the single ended test.

Appendix D: Device Discovery

The MST Device Scanner can be used to discover and change the IP address of IMPACT devices from

any PC connected to the same network. Upon opening, the Device Scanner will automatically scan for

devices.

To use the Device Scanner, navigate to the folder where the program is stored, and double click

devicescanner.exe.

The Device Scanner shows the columns of information for discovered devices:

 Name - The hostname of the device. For the NS50, the default name is MST Wireless Switch.

 IP Address - This can be set remotely on the NS50, in Settings > LAN > LAN Settings , or from the

Device Scanner (see below).

 Type - The device type or model. NS50 units will show an entry for each WAC, e.g. NS50 2F R1

 and NS50 2F R2.

 MAC Address - The MAC address of the device.

 Interface - The network interface via which the Device Scanner is communicating with the device.

 ID - The serial number on the device casing.

 Firmware - The version number of the firmware running on the device.

 Status - The uptime of the device. This can be used to easily determine which devices have recently

been connected to the network.

 Revision - The hardware revision of the device.

To manually discover new devices after the program has been opened, click the Scan button. To allow

the Device Scanner to continually check for new devices, tick the Continuous checkbox.

To change the IP address or settings of a device, click the Configure IP button. This will open a dialogue

box allowing you to set the device to Obtain an IP address automatically using DHCP, or to manually
