Product description

The communication unit MEg202.5 in its basic configuration provides remote transmission
of states or changes of binary inputs and commands by GSM / GPRS, UMTS / HSPA and LTE
networks of mobile operators. The measured values are transferred through the serial communication
line RS485 from connected measuring devices. It implements the standardized
communication protocol according to EN 60870-5-104:2006 standard and enable the connected
devices to be integrated in the SCADA system either directly or by means of data
The MEg202.5 unit contains a processor that communicates with connected devices, optimizes
and controls the data transmission, provided for pre-processing the data readout from
the measuring devices, supervises the connected devices and in case of an event it conveys
the information to the superior system.
The MEg202.5 unit can be used also in the function of a communication converter GPRS /
UMTS / HSPA / LTE on RS485 bus when the data sent through the mobile operator network
are re-sent in transparent mode to the programmed RS485 channel and conversely, the data
from RS485 are sent back.
The basic functional setting of the units is configured by the manufacturer. The setup change
can be made by program M202 Param.
