    • Supports various network protocols.
      Immediately reports events and abnormalities of network devices and systems with light, sound, and voice.
    • Supports secure protocols such as HTTPS, SNMP v3, SSH.
      Secure communication with peace of mind.
    • This unit is equipped with a "Text to Speech (TTS)" function that converts text data to voice.
      Text information can be converted to voice and registered, and voice notification can be performed in real time by command control.
    • Equipped with an SNMP device monitoring function in addition to dead/alive monitoring by PING monitoring.
      When the MIB information of the network device is actively acquired and the set conditions are met, the administrator is notified immediately by light and sound.
    • Mail Reception Detection (NHV-M only)
      The NHV-M unit accesses the mail server and will light up or play a message when emails that meet preset conditions are received.

    Monitoring Functions


    Email Transmission

    Send email alerts of various network events to up to 8 addresses. The subject and body can be customized and can be automated to be sent in a variety of situations.

    Email Reception Detection (M Model)

    The NHV-M unit accesses the mail server and will light up or play a message when emails that meet preset conditions are received.
    No PC is required because the NHV-M accesses the server directly, so no modification is needed to the existing system.

    PING Monitoring

    Ping up to 24 nodes simultaneously. While Ping is a basic diagnostic tool, the NHV Network Signal Tower is able to notify you based on your priorities. For example, low priority ping response failures may trigger a flashing light, while higher priority failures will trigger an MP3 voice alert, send an email and flash a light.

    Trap Monitoring

    As one of the oldest standards for network equipment fault notification, most network devices support SNMP traps. The NHV Network Signal Tower is able to send, receive and analyze trap information and respond appropriately.


    HTTPS Command

    HTTPS (Hypertext Transfer Protocol Secure) is an application-layer protocol designed within the framework of the Internet protocol suite. The NHV Series accepts HTTPS commands sent through a web browser or PLC to trigger NHV Series visual and audible alert functions.

    SSH/RSH Command

    Secure Shell (SSH) and Remote Shell (RSH) are a command line program that execute shell commands on remote hosts such as the NHV Series. SSH/RSH can be used to automatically run commands based on event information from network management software and various monitoring tools on the NHV Series to trigger visual and audible alert functions.

    SOCKET Communitation

    Sockets allow communication between PCs and is used in a client-server application framework. The NHV Series accepts an application-level protocol called PNS (developed by PATLITE) to establish connection between client and server and to control visual and audible alert functions.
