  1. Highlights of this release

  • New product SiteManager 1139 4G-CN and SiteManager 3339 4G-CN with support
    for Chinese 4G/LTE standards.

  • LinkManager now supports Windows 10.

  • Layer2 support (for initial device discovery and configuration).

  • Support for GateManager 6.0 "fast data tunnels".

  • LinkManager dynamic bandwidth adaptation for better end-to-end data flow.

  • Support for UNICODE characters in appliance name and domain tokens.

  1. New features and improvements


  • Add support for Windows 10. (#6988)

  • Add support for generic "Layer2" agents. (#6630)

    This feature allows programs, such as Siemens TIA portal and Schneider
    SoMachine, which rely on low-level, non-routable discovery and control
    protocols, to connect seamlessly through the LinkManager and SiteManager.

    Notice that using a Layer2 agent typically has lower throughput than
    using a dedicated agent for a device, since end-to-end buffering and
    throttling for Layer2 protocols is less effective than for higher
    level protocols based on TCP and UDP.

    Layer2 agents use a "yellow shield" icon to remind the user that these
    agents should only be used for special purposes like device discovery,
    pairing of new devices, etc.

    Notice that doing a to a SiteManager will not include
    Layer2 agents; if a connection to both normal and a Layer2 agents is
    required, use an agent group. However, an agent group may only include
    one Layer2 agent; if more than one is used, the result is unpredictable.

  • Add support for "Fast Data Tunnels" via GateManager.
    This feature has a lighter load on the GateManager, and reduces data
    buffering and throttling inside GateManager which improves end-to-end
    performance over "unbalanced" lines between LM/GM and GM/SM. (#6471)

  • In addition, LinkManager has a new Connection Speed Control (CSC) auto-tune
    feature, which dynamically adjusts the transmission speed to the available
    end-to-end bandwidth through the Fast Data Tunnel.
    The LinkManager Console will show the currently available bandwidth and there
    is also a user option to temporarily disable (and restart) CSC if the
    actual bandwidth "auto-tune" seems to be too aggressive.

  • Add mouse-over to explain appliances in LM console. (#6793)

  • Check if some other Secomea Software (such as TrustGate SoftClient) is
    already running on the same PC when installing LinkManager, and offer
    to Abort (cancel LinkManager installation), Retry (after shutting
    the other Software down), or Ignore (continue running both at own risk).

  • LinkManager GUI now supports using UNICODE characters in passwords
    and the integrated CHAT feature. (#6761 #7231)


  • SiteManager 14xx models now includes 5 agents (not expandable). (#7080)

  • SiteManager 34xx models now includes 25 agents, expandable to 100 agents.

  • Add support for "Fast Data Tunnels" and "auto-tune" via GateManager
    [see above]. (#6471)

  • Add support for generic "Layer2" agents [see above]. (#6630)

  • SiteManager GUI now supports using UNICODE characters in input fields
    and the integrated CHAT feature.

    When writing UNICODE into the configuration, they are converted using the
    generic HTML 〹 format, which is compatible accross all SiteManager
    releases and models. (#6761)

  • The appliance name and domain token fields may now contain up to 250
    characters (after conversion to the 〹 format).
    Notice that the field values may be truncated by the GateManager
    depending on the server's limits (typically 48-64 UNICODE characters
    or 128 ASCII characters). (#6881)

  • Add "Always + Static Routes" choice to the DEVx "Auto-subnet agent" settings.
    When selected, this enables forwarding of traffic from a LinkManager to any
    of the subnets specified in the SiteManager's Routing > Static Routes which
    have a gateway on the corresponding DEVx interface. (#7072)

  • Append [Mobile broadband] instead of [3G] to SiteManager model name
    when a (USB or internal) modem is detected. (#7149)

  • Allow using "DEV1", "DEV2", etc as aliases in IP/Hostname configuration
    settings. (#7153)

  • Allow static IP configuration of WiFi client interface. (#6617 #6856)

  • Avoid browser's offering to save passwords which are not related to the
    user login (e.g. Web proxy password).
    You may notice that password fields on the SiteManager GUI will be
    cleared temporarily when clicking on the "Save" button. (#6684).

  • To reduce confusion about the default password, it is now identified as
    (MAC address) rather than (Serial number), since the physical label on the
    SiteManager does not explicitly identify the printed "MAC address" as a
    serial number. (#7024)

  • Use the MAC address as default WiFi key in client mode. (#6933)

  • Local certificate (for EasyTunnel) is now SHA256 signed.

  • Remove per-agent and per-relay "Encr" options to remove the risk of
    sending data unencrypted due to a user mistake. (#6471)

  • Improve validation of EasyTunnel settings, and disable the feature
    if any of the values are deemed invalid. (#7122)

  • No longer send interface link up/down audit log events to GateManager.

SiteManager Embedded

  • Add support for GateManager Discovery Service. (#6471)

  • Add "No SiteManager Embedded license" message on SETUP wizard. (#6970)

  • Show "Pending SiteManager Embedded license from GateManager" message
    until SM-E has connected to a GateManager for the first time (#6965).

  • Show "Deleted on GateManager" when applicable. (#6965)

  • Add online help for "agent parameters". (#7099)

  • Added SM-E status API: (#7082)
    A HTTP request "" will now return the "icon
    state" and mouse over text of the (possibly non-existing) tray icon.

Mobile Broadband

  • Add support for new variant of Huawei E303/E3131. (#6838)

  • Add support for Huawei EC3372. (#6649)

  • Add support for Forge SLM630. (#6992)

  • Add support for several other USB modems.

  • Add APNs for China Telecom. (#7161)

  1. Bug Fixes


  • The LinkManager Installer has been optimized and should run a lot faster
    for a fresh installation.

  • When the LinkManager Installer is used to upgrade an existing LinkManager,
    it will now uninstall all previously installed versions of various drivers,
    so that only the newly installed drivers exist when the installation
    completes. This means that it may take some additional time to upgrade
    to LinkManager 6.0, but future updates should run much faster.

  • The GateManager administrator login link now uses https protocol. (#6687)


  • In a dual-UPLINK setup, an operational GateManager connection was typically
    reconnected after approx. 1 minute after (re)starting the SiteManager.
    Now, this only happens during probing. If the first GateManager connection
    is using a lower priority UPLINK interface, and a higher priority interface
    becomes operational. (#4726)

  • Improve compatibility with some WiFi Access Points, where SiteManager
    previously failed to get an IP address. (#6267)

  • When doing a WiFi scan, say "No IP Address" instead of "Connected" unless
    SiteManager has actually been assigned an (operational) IP address. (#6208)

  • On the Setup Wizard, show WiFi Down in "Red" instead of "Green" (#6208)

  • Fix display of frequency and signal quality of integrated WiFi. (#6208)

  • Don't retry modem setup if SIM code is wrong or missing. (#6898)

  • Stability fixes for SiteManagers with integrated WiFi. (#6828)

  • The IO port status was sometimes missing on the GateManager > Alerts page.

  • A long-time running SM could fail to connect via PPPoE or using SMS-Wakeup
    via 3G. (#5460, #6613)

  • Fix missing detection of 3G modem in some cases when another USB device
    is plugged in. (#6231)

  • Fix rare situation where the SiteManager could fail to reboot itself.

  • Fix inability to upgrade SiteManager firmware due to too little free
    memory to load and validate the firmware upgrade image. (#7017 #7228)

    Include "available memory" information in extended status.

  • Do not start (and show error for) a Generic > Device agent with no
    specified ports or services. (#6366)

  • Automatic "device service detection" would continue to run after disabling
    an agent using that feature. (#7140)

  • SMS Wakeup Parameters field is now marked as mandatory if UPLINK Mode is
    set to SMS Wakeup. (#6315)

  • No longer log receiving of malformed UDP packets in the system log. (#4546)

  • Improved Ethernet driver stability under heavy network load. (#7173)

  • Specifying a WiFi SSID but no WiFi Key would continuously reboot the
    SiteManager every 5 minutes. (#6933)

  • Setting UPLINK2 mode to SMS Wakeup was cleared by restart. (#6918)

  • Disable UPLINK load-balancing on SiteManagers (since they only have one
    UPLINK Ethernet port). (#6664)

SiteManager Embedded

  • Fix minor memory leak when accessing the SM-E GUI. (#6789)

  • Fix Ping and Restr checkboxes misalignment on GateManager > Relays page.

  • Fix missing connection cleanup after failure in SM-E for Linux. (#7009)

  1. Upgrade information

Hardware Products

  • Starting with release 5.2, the SiteManager firmware file format has been
    extended to include digital signatures, and once updated to this revision,
    it is not possible to downgrade the firmware to an older version than 5.2
    via the SiteManager web GUI, as older SiteManager firmware files do not
    have the required digital signatures.

    If - for some reason - you need to downgrade to an older firmware without
    the required digital signatures, you can use the "Upgrade firmware"
    command in the GateManager portal.

Software Products

  • Note that all Software products - LinkManager, SiteManager Soft,
    and SiteManager PC - must be upgraded by running the corresponding
    Setup program using an administrator account.
    Except for SiteManager Soft, you must use the Setup program corresponding
    to the Windows architecture (32 or 64 bit).

  • LinkManager and SiteManager PC come with a set of Windows drivers that
    will be installed or upgraded when running the Setup program. You may
    have to confirm the installation of these drivers.

  • First time you start the LinkManager after the upgrade (or after a new
    installation), you may be prompted to accept the installation of
    Secomea's CA certificate as a trusted root certificate. You should
    allow this to prevent Windows from looking for new drivers on the
    Windows Update site each time you establish a serial or USB connection.

  • SiteManager Soft requires VMware to operate, also after the update.

  1. Known issues or limitations


  • SiteManager WiFi supports WPA/WPA2 and TKIP/AES encryption.
    WEP is not supported.

  • WiFi access points that require web page login are not supported.

  • Note that using the PPI option requires optimal bandwidth for both
    the LinkManager and the SiteManager. This is due to the PPI protocol and
    Step7 software by design do not take into account the delays (latency)
    that may occur when relaying the communication over long distances.

  • The Siemens Step5 agent requires optimal bandwidth for both the LinkManager
    and the SiteManager.

  • When UNICODE is used in agent names, the output under Log > View will
    show encoded versions of the names, so they are not legible to the user.


  • When connecting to a Layer2 agent with LinkManager on Windows XP, the
    Layer2 adapter will only be operational after a restart of the Windows
    If the LinkManager has been restarted you need to reboot your computer to
    reenable the layer2 support. (#7254)

  • The LinkManager account name is used as the LinkManager's appliance name
    in the GateManager portal and in the LinkManager console. If the account
    name includes UNICODE characters, these are shown as ~ in the corresponding
    LinkManager appliance name.

  • Even though it is possible to configure and connect to multiple USB agents
    on a given SiteManager, it is currently not possible to use more than one
    device of any given type (there is currently no way to differentiate
    between such identical USB devices).

  • Due to restrictions on secure web-site certificate authentication, most
    modern browsers may prevent you from accessing https based services via
    the LinkManager's Go To Appliance functionality in the non-activated
    state (Domain view).

    This is because the Go To Appliance function uses a different IP address
    than the actual IP address of the remote device, so the browser suspects
    that the target device's certificate (typically self-signed) may be a

    There is no easy way to get around this problem, so you will have to
    follow the somewhat tedious procedure of your browser to bypass the
    warnings and connect to the device anyway.

    Note: You should not store the certificate permanently in Firefox.

    Go To Appliance in GateManager and LinkManager Mobile does not have this
