to be responsible for the conversion of communication protocol.
As a hardware function, it turns RS-232 signal into frequency
signal or change the frequency signal to RS-232 signal as versus
as well. The V.29 Modem Card provides either Bell 202 1200bps,
CCITT V.23 1200bps, V.22bis 2400bps, or V.29 9600bps
standard for using on 2/4 Wire Leased Line.
 GPRS/ 3G Modem Card: is GPRS (General Packet Radio
Service) Modem Card is based on GSM data delivery technique
which is different from the former channel transmission, by using
the "Packet" mode to deliver data. Due GPRS
provide a high-speed, non-disconnect and billing under quantity
bases, which is capable to support high security connecting
environment, lower communication charges and provide a faster
connecting method. By using the MDVPN supported by
telecommunication service, and use the wireless devices to
read/write the database, to save the hardware cost. Moreover the
wireless device is also support the "Group-Setting" function, by
using the GSM digital certificated with VPN Channel to send and
receive information.
 Voice+Data Modem Card: is the abbreviation for FSK Modem
working with 4 wire channel. The modem work as voice
transmission within data transmission in same time. The baud
rate of 600 bps in method of ani-synchronous protocol that you
can send Asynchronous and also Synchronous data frame over
the RS232 standard of modem. Modem has channel filter for
mixing input 4x wire channel as voice input with FSK signals and
transmit them over the 4kHz analog voice band. As a hardware
function, it turns RS-232 signal into frequency signal or change
the frequency signal to RS-232 signal as versus as well.
In a V-RTU2000 Series system, backplane is very important. If any
failure out of it which will affect the entire system operation and very
hard proceed maintenance; V-RTU2000 Series backplane is with
simple "Connector" and "Switch" of reliable mechanical part mounted
on a mother PCB. The connection between Backplane and other
cards is using "DIN 41612 C" connectors which with high reliability.
The backplane of V-RTU2000 Series is consisted of one PCB and
protection cover. Depending on different RTU type, the backplane
accordingly come with different number of I/O slots. The inside of
backplane is installed with DIN 41612 C (96-pin or 48-pin) Female
Connector for linking all cards; whereas, the backside of slot is
provided with pluggable type terminal block for external wiring.
