( full specifications are in the manual for the device )
1. Initiative interface converter (equipped with a built-in GPRS modem) is designed to transmit
daily/hourly reports on gas flow calculators via the Internet to the server of the user's dispatch service.
Devices are equipped with one or two slots for installing SIM-cards.
Initiative interface converters provide the ability to transmit data from all objects simultaneously.
This allows you to quickly receive data from a large number of calculators of gas metering units.
The proactive converter automatically polls the flow calculators and transmits the results
calculation to the specified user addresses at the specified time. (The number of polls per day and the time of transmission of the calculation results
user defines it).
The Converter also provides traditional access to the Calculator upon initiative requests from dispatcher programs.
interrogation and maintenance of Calculators.
2. The initiative interface converter is not a measuring instrument.

PS. - Attention! - If necessary, the user can
independently configure the Interface Converter with the initiative program "VexnaServ.exe"
in accordance with the recommendation of these programs during configuration.
To set up data exchange between the Calculator and the Interface Converter, it is necessary to set
address of the connected VR-2 Calculator (PC-B Calculator) and Internet connection parameters according to the inserted SIM card
("www.kyivstar.net" - for Kyivstar, or "www.umc.ua" - for MTS, etc.).
