[ENG] [2PWR,v2SMS] Device Overview: Appearance and Basic Specifications of a Device

It is possible to plug up to two electricity consumers with a total capacity of 1000 Watts to a device through controlled electric 220V sockets. To be protected from a short circuit in load and/or exceeding a maximum allowable capacity, a device is equipped with automatic built-in self-resetting fuse. Load power distribution is random between two channels. Load connected to a device is controlled through own web interface, via  an SNMP protocol, using URL-encoded commands (HTTP API) and using SMS commands (for a NetPing 2/PWR-220 v2/SMS device with a built-in GSM modem). A watchdog feature is implemented in a device that allows automatically reboot connected equipment using power supply if it freezes or according to a previously specified schedule. Electric load is controlled for each of two channels independently. At the same time, each channel can be possibly set up individually.

Elements of a Front Panel

• two ports for connecting to the Ethernet network using plugs of RJ-45 type;
• «Reset» button to reset a device to default settings;
• a power cord of a device with a euro plug that is inseparably connected to a device;
• a jack for plugging GSM antenna (for a NetPing 2/PWR-220 v2/SMS device with a built-in GSM modem);
• a slot for a SIM card installation (for a NetPing 2/PWR-220 v2/SMS device with a built-in GSM modem)

Ports for connecting to the Ethernet network have two LEDs:

• CPU – glows continiously, is a device is powered; blinks 5-6 times when a device turns on (in the process of loading a microprogram); blinks 15-20 times when parameters of a device are reset to default values; blinks from time to time when a device sends packages to the Ethernet network; blinks intensively when indicating a software updating mode.
• RX – glows if a network connection is set (shows the presence of link) and periodically blinks when receiving packages.

Elements of a Back Panel

• Sockets for connecting a load that are «computer sockets». A load is connected using a specific cable «monitor – system unit» or a special adapter PWR-220 for a standard eauro plug. An adapter is not included into a shipping kit. Sockets are protected from a short-circuit in a load with built-in self-resetting fuse;
• 220 V LEDs on sockets «PWR1» and «PWR2». «PWR1» LED with a socket located above it corresponds to the first channel of power management, «PWR2» LED with a socket located above it corresponds to the second channel of power management. «PWR1» and «PWR2» LEDs near sockets for connecting a load glow if there is 220V power on a corresponding socket, and do not glow if there is no voltage;
• Socket for plugging sensors
