IP Watchdog

IP WatchDog monitors function of serial (RS-232) devices using PING, WWW page detection, or serial port data stream. If a preset function was not executed within a specified time period, IP WatchDog will RESET the device (or switch to a back-up communication circuit, set off an alarm etc.) A single WatchDog device can independently monitor up to two devices, such as servers, routers and access or security systems.

Monitoring of remote device functions:

  • IP Watchdog periodically pinged by monitored device
  • Monitored device periodically pinged by IP watchdog
  • IP Watchdog requests WWW page from monitored device
  • Monitored device requests WWW page from IP Watchdog
Monitoring of local device functions:
  • Monitored device sends periodically defined string to RS-232 serial port.





Overview of the IP Watchdog

  • Ethernet - RJ45 (10BASE-T - IEEE 802.3).
  • 1 serial port RS-232 (RxD, TxD, CTS, RTS, GND) - Setup mode 9600 8N1
  • 1 data input RS-232 (RxD)
  • Two independent relays intended to reset or start monitored devices.
    Relay and pin configuration depending on selected configuration (see available configurations)
  • Manual control (Startup / Shutdown / Restart) of monitored devices.
  • Time synchronization from internet / intranet, using TIME, NTP/SNTP or DayTime protocols.
  • Device configuration methods:
    • WWW page configuration of device activity, including option of manual relay control.
    • RS-232 Setup main parameters configuration over serial port from any RS-232 terminal - 9600 8N1.
    • UDP Config configuration of basic network parameters (MASK, IP, Gateway).
    • TCP Setup remote configuration of basic parameters in terminal over TCP.
  • Access security and relay control:
    • IP range - it is possible to define a range of IP addresses that can communicate with the device.
    • User name and password - Access to WWW pages and Serial / TCP setup
  • Power supply: 9-15 V DC
  • Dimensions: 25 x 82 x 90 [mm]
  • SW: Wide range of examples and previews for Windows and Unix/Linux.

  • PO (Power On) - after turn on, the external power supply leads out over (A = +, B = GND) switching contact (switched on after startup). Note: Recommended for connecting a power cable to device.
  • PF (Power Off) - after turn on, the A and B terminals are without potential (A = +, B = GND); switching contact (open after startup).
  • NO (Normally Open) - switching contact is open after the power on.
    Note: Recommended for parallel connected to the RESET button.
  • NC (Normally Close) - break contact is closed after the power supply turned on.
