Abbreviations and explanations

Xn
–
is a number of socket. This information are provided
for manufacturer’s
purpose and used in data schemas and connection diagrams.

GSM
– Global Standard for Mobile Communications.
This interfaces is prepared
for remote connections and data bidirectional data transfer over Global Standart
Mobile network.

GPRS - a packet oriented mobile data service on the 2G and 3G cellular
communication system's global system for mobile communications (GSM).

Ethernet - a family of computer networking technologies for local area networks
(LANs) commercially introduced in 1980. Standardized in IEEE 802.3, Ethernet has
largely replaced competing wired LAN technologies. This interfaces is prepared for
connection LAN (Local Area Network).

IP address - An Internet Protocol ( IP ) address is a numerical label that is assigned
to devices participating in a network that uses the Internet Protocol for
communication between its nodes.

TCP/IP
– Transmission Control Protocol is for communication between computers,
used as a standard for transmitting data over networks and as the basis for standard
Internet protocols.

MAC address
–
Media Access Control address is a unique identifier assigned to
most network adapters.

UART
–
An Universal Asynchronous Receiver/Transmitter is a type of
“asynchronous receiver/transmitter, a part of computer hardware that translates data
between parallel and serial forms. UART are commonly used in conjunction with
communication standards such as EIA RS-232, RS-422 or RS-485. Record (UARTx)
on top of enclosure also are used as serial interface number.

GND
–
ground wire contact

RS232 - the traditional name for a series of standards for serial binary single-ended
data and control signals connecting between a DTE (Data Terminal Equipment) and
a DCE (Data Circuit-terminating Equipment). It is commonly used in computer serial
ports. The standard defines the electrical characteristics and timing of signals, the
meaning of signals, and the physical size and pin out of connectors. RS232
interfaces are prepared for connection of pheripherical devices (example energy
meters, controllers, machines and etc.)
.

TD
–
contact for transfer data wire of RS232 socket

RD
–
contact for read data wire of RS232 socket

DTR
–
contact for Data Transmit Ready wire of RS232 socket

RS485 - standard defining the electrical characteristics of drivers and receivers for
use in balanced digital multipoint systems. The standard is published by the ANSI
Telecommunications Industry Association/Electronic Industries Alliance (TIA/EIA).
Digital communications networks implementing the EIA-485 standard can be used
effectively over long distances and in electrically noisy environments. Multiple
receivers may be connected to such a network in a linear, multi-drop configuration.
RS485 interfaces are prepared for connection of pheripherical devices (example
energy meters, controllers, machines and etc.).

A+
–
contact for positive wire of RS485 socket

B-
–
contact for negative wire of RS485 socket

USB
–
Universal Serial Bus is an industry standard, that defines the cables,
connectors and protocols used for connection, communication and power supply
between computer and electronic devices. USB type B socket is prepared for
connection to PC(Personal Computer). USB type A socket is prepared for
connection t
o pheripherical devices (example memory stick’s and etc.).

Socket
– is an endpoint of a bidirectional inter-process communication flow across
an Internet Protocol-based computer network, such as the Internet .

Data
–
contact for data wire

Req
–
contact for request wire

CL+
–
contact for current loop positive wire

CL -
–
contact for current loop negative wire
