OTMC 100 Series User Manual

1 Introduction & Designated Use

The OTMC 100 is an antenna-integrated GPS controlled time reference. It provides high-precision time to synchronize intelligent electronic devices (IEDs), computers and measurement equipment in Ethernet (TCP/IP) based networks. The OTMC 100 series products can be used as a PTP (Precision Time Protocol) grandmaster clock according to the IEEE 1588-2008 standard and as an NTP (Network Time Protocol) time server for NTPv4 compliant equipment according to RFC 5905.

The fields of application for the OTMC 100 series products include applications in industrial production involving automatic test equipment (ATE), time critical banking and telecom applications as well as protection and control applications in the electrical power industry. The OTMC 100 is the right choice wherever accurate time in a computer based network is needed.

Due to the unique combination of GPS antenna, GPS receiver and time signal processing, the OTMC 100 can be directly connected to Ethernet networks without the need of additional RF cable installation.

The OTMC 100 series is designed for outdoor use in lightning protected areas. It is intended for fixed installation on masts. For installation requirements, please refer to the Quick Start Guide provided with the product or chapter "Mounting" on page 14.

The following OTMC 100 models are available: OTMC 100i: Time reference for use in industrial applications supporting the IEEE 1588-2008 default

profiles. OTMC 100p: Time reference for use in the electrical power industry. In addition to the

IEEE 1588-2008 default profiles, the OTMC 100p also supports the power profile according to IEEE C37.238-2011 (IEEE Profile for Use of IEEE 1588-2008 Precision Time Protocol in Power System Applications) specifically used in the electrical power industry.

For reasons of simplicity this manual uses the general term "OTMC 100" if the features and functionality described are common for all products of the OTMC 100 series. The complete names OTMC 100i and OTMC 100p are only used to indicate differences between the models.

The unique design of the OTMC 100 series offers many advantages:

• Web browser interface (called Web Interface) allowing for intuitive and straight forward setup and control. The use of DHCP/Auto IP and the OMICRON Device Browser tool allows for easy remote access to all functions and features from a computer.

• Outstanding precision. Synchronized to the GPS satellite navigation system, the OTMC 100's internal clock achieves a time accuracy of +/- 100 ns to reference time (UTC).

• No need for rack space in server rooms due to outdoor mounting.

• Extremely low power consumption < 2 W.

• Full compliance with IEEE 1588-2008 (IEEE 1588 version 2).

• Easy installation. No additional power supply required through PoE (Power over Ethernet).

Introduction & Designated Use

• Ethernet cable length up to 100 m (standard Ethernet). Can be increased to up to 2 km by using fiber optic Ethernet and media converters.

• Automatic cable length compensation compensates errors due to propagation delays on the network.

• Automated configuration. The possibility to upload configuration files enables easy exchange and configuration of the hardware.

• The OTMC 100 enables redundant configurations as defined in IEEE 1588-2008. The best master clock algorithm (BMCA) guarantees that the best clock in the system is used as the master clock. An automatic changeover to another clock is performed if the active master clock no longer provides sufficient time accuracy.

• Due to its integrated NTP server functionality the OTMC 100 can also be used in networks containing devices that are not yet ready for PTP. The OTMC 100 is able to simultaneously operate as NTP server and PTP grandmaster clock.

The following features are supported by the OTMC 100 software:

• Time:

• IEEE 1588-2008 version 2 support:

Device Overview

4 Mounting

4.1 Safety Instructions

A position with good view to the sky will usually be located in a lightning endangered zone outside of a building. The OTMC 100 must not be exposed to direct lightning strokes and thus has to be protected sufficiently. Therefore, the OTMC 100 has to be mounted in an area protected by a lightning protection system according to the relevant standards and regulations. The user is responsible for sufficient lightning protection of the device and the observance of all lightning protection regulations relevant for the site of installation.

Always use the waterproof RJ45 Ethernet connector supplied with the OTMC 100 in order to maintain the watertightness of the device. Do not use the OTMC 100 outdoors without a waterproof connector inserted.

CAUTION! Risk of injury or damage due to high voltages caused by lightning stroke.

• The installation of the OTMC 100 and the implementation of lightning protection measures have to be performed by accordingly qualified experts.

• Always observe all relevant lightning protection regulations.

• The local lightning protection regulations and the protection concept of the building and the electrical installation may require a suitable surge protection device for the Ethernet network cable leading into the building.

• For outdoor installation always use shielded Ethernet cable. The cable shield has to be connected to the shield of the Ethernet connectors.

4.2 Suitable Mounting Positions

The OTMC 100 receives the time information from the satellites of the GPS system. However, GPS reception generally requires a plain line of sight between the antenna and the satellites.

For proper function, the OTMC 100 requires signal reception from at least 4 GPS satellites. The more satellites it can receive, the more reliable the time information the OTMC 100 can deliver.

The OTMC 100 should generally be mounted outdoors at a location that provides free view in a range of 180° vertically to the sky and 360° horizontally around the device. The view to the sky must not be blocked by any objects. This is usually given when mounting the OTMC 100 on a roof or a sufficiently high mast. Refer to the figure below.

You should furthermore consider that GPS signals may be reflected by large buildings and structures around the OTMC 100, which may deteriorate the timing accuracy of the OTMC 100.

Always mount the OTMC 100 in an upright position with the protective cap to the top, as shown in the figure below. The RJ45 connector on the base plate of the OTMC 100 must point vertically downwards. Do not mount the OTMC 100 inclined to any side or with the base plate to the top!

Do not move the OTMC 100 during operation. Changing the position of the OTMC 100 during operation causes time errors.

OTMC 100 Series User Manual

5 Connection, Access & Initial Setup

5.1 Connecting the OTMC 100 to an Ethernet Network

Note regarding network switches:

The precise synchronization of clocks via Ethernet networks requires that the propagation delay times for data packets is constant on the entire network. Network switches that do not provide transparent clock functionality may introduce jitter and thus influence the propagation delay. Therefore, the OTMC 100 will only be able to provide highly accurate time synchronization in networks that that are equipped with network switches providing transparent clock functionality as specified in IEEE 1588-2008 or that do not have a network switch at all.

Do not connect conventional RJ45 connectors that are equipped with a locking tab to the OTMC 100! The locking tab of such connectors cannot be accessed directly anymore after inserting the plug to the OTMC 100. In this case, a small screwdriver must be used to carefully unlock the RJ45 connector in the socket. Use the waterproof RJ45 connector supplied with the OTMC 100 instead or, when using a cable with a conventional RJ45 connector (for test purposes only!), break off the locking tab at the RJ45 connector before inserting it to the OTMC 100.

The OTMC 100 is supplied with power by Power over Ethernet (PoE) according to IEEE 802.3af. If the network port the OTMC 100 is connected to does not provide PoE, a PoE injector has to be used as shown in the figure below.

The OTMC 100 supports Ethernet cable lengths of up to 100 m without the need of repeaters. By using additional media converters the use of optical Ethernet is possible, which allows much longer distances. Depending on the used variant it is possible to cover distances up to 2000 m. For further details, please refer to the user manual of the media converters used.

The OTMC 100 automatically powers up after inserting the RJ45 plug and providing supply voltage to the OTMC 100. After the device is supplied with voltage, the LED first lights up red for approx. 15 s during the boot process and then changes to green to indicate operational readiness.

The OTMC 100 is a class 1 powered device (PD) as defined in IEEE 802.3af (power consumption < 3.84 W). The network port the OTMC 100 is connected to must be able to supply a class 1 powered device.

CAUTION! Risk of injury or damage due to high voltages caused by lightning stroke. The local lightning protection regulations and the protection concept of the building and the electrical installation may require a suitable surge protection device for the Ethernet network cable leading into the building.

5.2 Accessing the OTMC 100 from a Computer

The OTMC 100 automatically powers up after supply voltage is provided via Ethernet (PoE). The LED lights up green when the device is ready for operation.

After that, a network IP address is assigned automatically in order to connect the device to the network. If a DHCP server is available in the network, the IP address is assigned by the DHCP server. If not, the OTMC 100 automatically selects and assigns a link-local IPv4 and IPv6 address by itself.

The OTMC 100 can be configured completely via the Web Interface using a computer. This way, no manual intervention at the device itself will be required under normal circumstances.

5.3 Next Steps to Set Up the OTMC 100

After connecting the OTMC 100 to the network and accessing the device from your computer, you have to configure the OTMC 100 according to your needs.

See chapter "The OTMC 100 Web Interface" on page 34 or the OTMC 100 online help for a detailed description of the Web Interface, or section "Operating Procedures Performed via the Web Interface" on page 27 for a description of the most important operating procedures.

Proceed as follows to set up and configure your OTMC 100. Consult your network administrator if you do not know the correct settings.

1. Configure the network settings. Open the Configuration section of the Web Interface and display the Network page (see page

58). a. Configure the network/IP settings according to the needs of your network. Click the Save All

button to save and apply your settings.

By default, the OTMC 100 will attempt to get an IPv4 address via DHCP and assign an IPv6 address using the automatic configuration. If no DHCP server is available for IPv4, the OTMC 100 uses the zeroconf service to automatically assign an IP address on its own.

OTMC 100 Series User Manual

2. Configure the PTP settings. Display the PTP page of the Configuration section (see page 67). Select your configuration and click the Save All button to save and apply your settings. The most important PTP settings are:

a. PTP profile (General Settings tab): All PTP devices that should synchronize to each other must

use the same profile.

• Use the Default E2E or Default P2P profile for industrial environments. Default P2P (peer-to-peer) can only be used if the switches used in the network support and are configured for operation as peer-to-peer transparent clocks as defined in IEEE 1588-2008. Use Default E2E (end-to-end) if standard switches are used in the network and the higher synchronization error introduced by these switches is acceptable. The Default P2P profile and the Power Profile according to IEEE C37.238-2011 will not work with those network switches.

• Use the Power systems profile for power utility environments where all devices are known to use the Power Profile according to IEEE C37.238-2011 (OTMC 100p only).

b. Operation mode (General Settings tab): Always use the one step operation mode unless there

are devices in the network that do not correctly handle one step master clocks.

c. Domain number (Default Settings tab): All PTP devices that should synchronize to each other

must use the same domain number.

d. Transport (Port Settings tab): Select the transport mechanism according to the needs of your

network. All PTP devices that should synchronize to each other must use the same transport mechanism.

3. Secure your OTMC 100 against unauthorized access. Display the Security page of the Configuration section (see page 62).

a. Password (Access Control tab): Set up a password and select the Web Interface

authentication enabled option. Click the Change button to save and apply your settings. From now on, entering the password is required to access the OTMC 100.

b. Insecure HTTP (Access Control tab): By default, password transmission to the OTMC 100 is

performed unencrypted. By deselecting the Insecure HTTP enabled option you can force the use of the encrypted HTTPS protocol and thus protect your password. Click the Change button to save and apply your settings.

When accessing the OTMC 100 via HTTPS, an "untrusted connection" message may appear because the OTMC 100 does not have a valid certificate. To avoid such messages, it is necessary to provide the OTMC 100 with such a certificate. Please refer to subsection "Generate Certificate tab" in section "Security Configuration Page" on page 62 for more detailed information.

c. Protocol restrictions: Disabling services that are not required or used for operation will

minimize potential points of attack and thus make the OTMC 100 safer. Click the corresponding check box to select or deselect an option. Click the Save button to save and apply your settings.

• Usually the OMICRON Device Browser is used to find the OTMC 100 in the network. However, the OMICRON Device Browser may also be used to change the network configuration of the OTMC 100. To protect your OTMC 100 against unauthorized or unintentional configuration changes using the OMICRON Device Browser, deselect the Allow OMFIND network configuration option.

• If PTP management messages are not used in your network, deselect the Allow PTP SET/ COMMAND management messages option. This will prevent modification of the PTP settings. Reading the PTP settings is still possible then. In order to completely deactivate the PTP management interface, deselect the PTP management interface enabled option in the General Settings tab on the PTP page of the Configuration section (see page 67).

• If you do not want to use the SNMP management interface to configure the OTMC 100, deselect the Allow SNMPv2c community write access option.

• If you want to prohibit standard user/password authenticated access to the OTMC 100 via secure shell (SSH), deselect the Allow SSH password login option. When deselected, access via SSH is only possible via key based authentication. This reduces the risk of unauthorized access to the OTMC 100 through brute force attacks.

The options in the Protocol Restrictions tab of the Security page just enable or disable protocol options. In order to completely disable a service, open the Services tab of the Network configuration page.

IPv4), "UDP_IP_V6" (transport of the PTP packets via UDP over IPv6), and IEEE_802_3 (transport via Ethernet packets according to IEEE 802.3).

Vlan ID Displays the Vlan ID. The Power Profile according to

IEEE C37.238-2011 requires an IEEE 802.1Q VLAN tag. This value represents the VID (VLAN Identifier) field (12 bits) within the TCI (Tag Control Identifier). See IEEE C37.238-2011, clause 5.6. Only available

for Power Profile (OTMC 100p only).

This parameter is set in the PTP configuration (see page 67) .

OTMC 100 Series User Manual

Vlan priority Displays the Vlan priority. The Power Profile according to

IEEE C37.238-2011 requires an IEEE 802.1Q VLAN tag. This value represents the PCP (Priority Code Point) field (3 bits) within the TCI (Tag Control Identifier). See IEEE C37.238-2011, clause 5.6. Only

available for Power Profile (OTMC 100p only).

This parameter is set in the PTP configuration (see page 67) .

7.2.2.2 Default tab

The Default tab displays the current configuration/state of the internal PTP clock of the OTMC 100. When the OTMC 100 is in the master state, the slave clocks in the network/domain in which the OTMC 100 participates are synchronized to this clock. The data listed here correspond to the Default Dataset specified in IEEE 1588-2008, clause 8.2.1.

Two step Indicates whether the OTMC 100 is operating as a two step clock (true)

or as a one step clock (false), see IEEE 1588-2008, clauses 7.3.8.3,

8.2.1.2.1 and 13.3.2.6. This parameter is set in the PTP configuration (see page 67) .

Clock identity Displays the clock identity. IEEE 1588-2008, clause 7.5.2.2, requires that

each clock in a PTP network has a unique clock identifier. This identifier is an 8-octet array. The OTMC 100 automatically sets the clock identity to a unique value based on the device's MAC address according to IEEE 1588-2008, clause 7.5.2.2.2.

Clock class Displays the current clock class of the OTMC 100 (see IEEE 1588-2008,

clause 7.6.2.4). The clock class is broadcast in the corresponding PTP data packets. The value of the clock class parameter is automatically set by the OTMC 100 depending on the source of time that is currently available:

PRIMARY_REF_PTP (6) The clock of the OTMC 100 is locked to a primary reference time source, i.e., to the GPS system.

PRIMARY_REF_PTP_HOLDOVER (7) The clock was previously locked to GPS time but has lost GPS reception. The internal oscillator of the OTMC 100 is used as the source of time and provides time with the accuracy given by the Clock accuracy parameter.

NOT_IN_SPEC_PTP_A (52) The clock is not locked to GPS time and is not within its holdover specification.

The OTMC 100 Web Interface

Clock accuracy Displays the current accuracy of the OTMC 100's internal clock with

regard to TAI. See IEEE 1588-2008, clause 7.6.2.5 for details. This parameter is determined automatically by the OTMC 100, considering the quality of the current GPS reception.

Clock variance Displays the clock variance. The clock variance parameter is set to the

PTP variance value specified by IEEE 1588-2008, clause 7.6.3. This parameter gives a measure for the stability of the internal oscillator of the OTMC 100 and is used in the Best Master Clock Algorithm (BMCA) of the PTP protocol. The Clock variance of the OTMC 100 is set to a constant value that was determined from laboratory observations.

Priority 1 Priority 2

Displays the priority values of the OTMC 100. To each PTP master clock, two priority values (Priority 1 and Priority 2) may be assigned by the user. If more than one PTP grandmaster clock is available in the network, a clock with a lower Priority 1 value will always be the preferred master clock over a clock with a higher Priority 1 value (see IEEE 1588-2008, clause 6.6.2.3). A value in the range from 0 to 255 may be assigned to the Priority 1 parameter (see IEEE 1588-2008, clause 7.6.2.2).

The Priority 2 parameter (see IEEE 1588-2008, clause 7.6.2.3) is used if several devices have the same Priority 1 parameter value and the same clock quality (class, accuracy and variance). The Priority 2 parameter thus allows a finer grained ordering among otherwise equivalent clocks (see IEEE 1588-2008, clause 6.6.2.3). Lower values take precedence.

These parameters are set in the PTP configuration (see page 67) .

Domain number Displays the domain number of the OTMC 100. The domain number

specifies the PTP domain (see IEEE 1588-2008, clause 7.1) in which the OTMC 100 participates. All clocks in a network that shall be synchronized to each other must participate in the same PTP domain, i.e., have the Domain number parameter set to the same value.

This parameter is set in the PTP configuration (see page 67) .

Slave only Displays whether the clock is a slave-only clock (true) or not (false). See

IEEE 1588-2008, clause 8.2.1.4.4.

IEEE C37.238 grandmaster ID

Displays the grandmaster identity of the OTMC 100 to be transmitted in IEEE C37.238 TLV. By sending this ID, the OTMC 100 identifies itself as a valid power profile grandmaster. A power profile slave will ignore all masters that do not provide a setting for this field. Only available for

Power Profile (OTMC 100p only).

This parameter is set in the PTP configuration (see page 67) .

Attention: If you select the checkbox again, the OTMC 100 will automatically use the last valid password defined. Therefore, make sure to keep your password stored at a save place for future use even if you deactivate password protection. Perform a factory reset on the device if you forgot your password (see "6.2 Operating Procedures Performed Directly on the Device" on page 31). This will reset the OTMC 100 to the default password timeserver.

7.3.2.2 Generate Certificate tab

When accessing the OTMC 100 via HTTPS, an "untrusted connection" message will appear because the OTMC 100 does not have a valid certificate.

To avoid such messages, it is necessary to provide the OTMC 100 with such a certificate. There are two possible ways: Generating a certificate signed by an accredited certification authority or generating a certificate signed by yourself.

Web browsers usually contain the digital signatures of all accredited certification authorities by default and will therefore accept certificates signed by those authorities. However, when using a self-signed certificate, the web browser will not recognize you as a valid certification authority (since it does not know the signature of "your" certification authority) and thus not accept such certificates. This behavior

The OTMC 100 Web Interface

can only be eliminated by providing each web browser used to access the OTMC 100 with the digital signature of "your" certification authority. Due to this, generating a self-signed certificate will in most cases not be a feasible solution in practice. We recommend to generate a certificate signed by an accredited certification authority or to accept the "untrusted connection" message displayed when accessing the OTMC 100.

Proceed as follows to generate a certificate signed by an accredited certification authority:

1. Enter the reqired information to the fields Domain name, E-mail address, Country code (e.g. AT), State, Locality, Organization name and Organizational unit.

2. Click the Download button next to Generate certificate signing request to generate a certificate and download it from the OTMC 100.

3. Send the certificate to an accredited certification authority.

4. Upload the signed certificate received from the certification authority to the OTMC 100 using the Upload Certificate tab (see below).

5. The web browser will then recognize that the certificate has been signed by an accredited certification authority and therefore no longer display the "untrusted connection" message when accessing the OTMC 100.

Proceed as follows to generate a self-signed certificate:

1. Enter the reqired information to the fields Domain name, E-mail address, Country code (e.g. AT), State, Locality, Organization name and Organizational unit.

2. Click the Generate button next to Generate self-signed certificate to generate a certificate on the OTMC 100 that is signed by yourself.

3. Deselect the Insecure HTTP enabled option in the Access Control tab and click the Change button.

4. The OTMC 100 automatically performs a restart of the web server.

5. The web browser then displays an "untrusted connection" message. Add the certificate previously generated for the OTMC 100 to your web browser.

The approach to add the certificate to the web browser strongly depends on the browser used to access the OTMC 100. Please consult the help system of your web browser for a detailed description how to handle certificates with your browser.

Allow SNMPv2c community write access

Deselect this option to disable write access via the SNMP management interface in order to prohibit configuration of the OTMC 100 via the SNMP management interface.

Allow SSH password login If this option is enabled, the user can log in to the OTMC 100 via

SSH using the standard user/password authentication (i.e., using the user name and password defined for the OTMC 100) or using a public/private key pair previously generated by the user and copied to the OTMC 100.

Deselect this option to prohibit standard user/password authenticated access to the OTMC 100 via secure shell (SSH). When deselected, access via SSH is only possible via key based authentication. Deselecting this option reduces the risk of unauthorized access to the OTMC 100 through brute force attacks.

There are numerous instructions for generating SSH key pairs on the Internet.

OTMC 100 Series User Manual

7.3.4 NTP Configuration Page

The NTP server on the OTMC 100 requires an accurate time source before any NTP client can synchronize to it. Two time sources are possible: GPS or external NTP servers. If at least one time source becomes available, it will take a few seconds until the NTP server synchronizes to the time source.

Select the corresponding tab to specify your NTP configuration settings. Click the Save All button to save and apply your NTP configuration specified in the individual tabs to the OTMC 100.

7.3.4.1

External Servers tab

Use this tab to specify external NTP servers, for example to improve safety if the GPS signal fails. If you are exclusively using GPS as an NTP time source it is not necessary to specify an NTP server on this tab.

Server 1 Server 2 Server 3

Use the Server list box to select 1 to 3 sources the OTMC 100 should receive NTP time information from if it is not locked to GPS satellites. The more sources you specify, the more accurate is the NTP time information the OTMC 100 can deliver.

...

The OTMC 100 Web Interface

Server 1, 2, 3 (cont.)

Select IPv4 or IPv6 and enter the address of an NTP time server (e.g. pool.ntp.org) to the respective field. Or select Disabled if you do not want to use it.

Use the corresponding Minpoll and Maxpoll fields to enter the minimum and maximum polling interval as a power of 2 (i.e., in 2x seconds). For example, if you enter a value of 5, the OTMC 100 will poll the NTP time server every 32 seconds (= 25). Possible values: 4 to 17 resulting in an interval between 16 and 131072 seconds.

7.3.4.2 Broadcast Mode tab

The most common configuration is the client/server mode where every client sends a request to the server to retrieve the current time. No separate configuration is required for this mode.

The broadcast/multicast mode works by broadcasting the time into the network. In this case, the clients must be configured to listen for broadcast/multicast messages in the network. This mode can be configured on this tab.

Explanation:

Broadcast means that data packets are sent from one point (here: OTMC 100) to all other subscribers of a computer network. Broadcast is not supported by IPv6.

Multicast means that data packets are sent to a specific subset of subscribers only. This subset of subscribers is specified by an address range, the multicast address. Multicasting therefore allows much more efficient distribution of information.

OTMC 100 Series User Manual

IPv4 Broadcast Select the Enabled check box to enable the sending of IPv4 broadcast

messages containing NTP time information. If enabled, enter the broadcast IP address in dot-decimal notation (e.g.:

192.168.0.255). Minpoll specifies the interval for sending the broadcast messages as a power of

2 (i.e., in 2x seconds). Possible values for Minpoll: 4 to 17 resulting in a broadcast interval between 16 and 131072 seconds.

IPv4 Multicast Select the Enabled check box to enable the sending of IPv4 multicast messages

containing NTP time information. If enabled, enter the IPv4 multicast address in dot-decimal notation (e.g.:

224.0.1.1). Minpoll specifies the interval for sending the multicast messages as a power of 2

(i.e., in 2x seconds). Possible values for Minpoll: 4 to 17 resulting in a broadcast interval between 16 and 131072 seconds.

IPv6 Multicast Select the Enabled check box to enable the sending of IPv6 multicast messages

containing NTP time information. If enabled, enter the IPv6 multicast address in hexadecimal notation (e.g.:

ff05::101). Minpoll specifies the interval for sending the multicast messages as a power of 2

(i.e., in 2x seconds). Possible values for Minpoll: 4 to 17 resulting in a broadcast interval between 16 and 131072 seconds.

See the "ntp.conf man page" for a more detailed description of the NTP parameters (see Linux command "man ntp.conf").

8 Automation Interface

The OTMC 100 series offers secure shell (SSH) access to its internal Linux operating system for remote configuration.

It provides the following functionality:

• Configuration management (backup and restore)

• Download of log files

• Usage of Linux shell utilities (e.g. ping)

8.1 Access

The OTMC 100 supports TFTP, FTP and SSH access. By default you can login via FTP/SSH using the user name omicron and the password timeserver. The Web Interface, the SSH, and the FTP server use the same password. Therefore, changing the password in the Web Interface will also update the password for the other services.

Anonymous access is possible via TFTP and FTP, however, without the option to upload files. In order to upload files, we recommend the secure SCP (Secure Copy) instead of FTP, where passwords are not transmitted in plain text. Note that the TFTP and FTP services can also be disabled if not needed.

The log and configuration files are located in the home directory of user omicron ("/home/omicron") in the respective subfolders "config" and "log".

8.2 Configuration

All configuration options are stored in a single XML file that can be edited easily. The XML file contains the same options as the Web Interface (which is in fact just a front end for the XML file). Additionally, an XML Schema Definition (XSD) is provided to ensure that only valid configuration options are set.

This makes it possible to easily clone a device even from distant locations. Just download the configuration file from one OTMC 100, edit it if required (e.g. change the IP address) and upload it to another OTMC 100.

Further instructions regarding the automated configuration via SSH can be found in the readme file located under "/home/omicron/doc/readme.txt".

9 The OMICRON Device Browser

By means of the OMICRON Device Browser you can access network compatible OMICRON devices. The Device Browser automatically finds all OMICRON devices available in the computer network.

Having the Device Browser installed on your computer, the OMICRON devices may be displayed in one of two ways:

1. When using the regular Windows Explorer, the OMICRON devices appear in the Windows Explorer’s folder tree in a section called OMICRON Devices, their serial numbers presented like regular first-level folders.

If necessary, right-click on a free area of the Windows Explorer’s folder tree and select the Show all folders option to display the OMICRON Devices section in the Windows Explorer.

2. Alternatively, double click the OMICRON Devices desktop icon. This launches a Windows Explorer window listing the OMICRON devices detected in the computer network with their serial number, device type/name and IP address.

There is no functional difference; use whatever method is more convenient for you. Even though the Device Browser help system focuses on accessing devices via the "regular" Windows Explorer, when working from the OMICRON Devices Explorer window, the handling is basically identical.

Click the help button in the top right corner of the Device Browser Explorer window to view the Device Browser help providing detailed information about the Device Browser.

The OMICRON Device Browser

9.1 Installing the OMICRON Device Browser

The OMICRON Device Browser and its installation program Setup Wizard are included on the CD ROM accompanying the OTMC 100. Proceed as follows to install the OMICRON Device Browser:

1. Exit all other major programs running on your computer.

2. Insert the CD ROM into your computer’s CD ROM drive and click Install Device Browser on the start page. Should the start page not be displayed automatically a few seconds after the CD has been inserted into the CD ROM drive, change to the Windows Explorer and double-click autorun.exe on the CD ROM.

3. Follow the instructions displayed on the screen to install the software.

Note regarding firewall requirements: The OMFind service sends and receives network packets on UDP port 4987 and 4988. The OMICRON Device Browser installer will configure the Windows firewall appropriately during installation on supported systems. If you have a separate "personal" firewall enabled, ensure that UDP ports 4987 and 4988 are open for the OMFind service.

9.2 Finding OMICRON Devices in the Device Browser Manually

(OMFind)

Normally the Device Browser automatically finds the OMICRON devices connected to the network. If not, it is also possible to manually search the network for available OMICRON devices.

Proceed as follows:

1. Right-click the OMICRON Devices desktop icon.

2. On the context menu, select OMFind and then click Find Devices.

3. This will start the Device Discovery tool. This tool is intended to diagnose network/firewall problems when the Device Browser lists no or not all expected test sets.

4. Click the Start Discovery button to manually search for OMICRON devices connected to the network. Once the search is finished, the Discovered devices section lists network parameters of all found OMICRON devices.

Some of the available firewall/tunneling products are capable of stopping even the Start Discovery feature of the Device Discovery tool. So you will not find any OMICRON devices on the network this way. In this case, the network parameters list stays empty once a search is finished. If you experience such a behavior, this may indicate a firewall/tunneling software blocking the network communication.

OTMC 100 Series User Manual

Click the help button in the top right corner of the Device Browser Explorer window to view the Device Browser help providing detailed information about the OMFind service.

9.3 Accessing the OTMC 100 Web Interface
