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.
