The OnCell G3100 is
an intelligent, industrial, quad-band GSM/GPRS/EDGE IP modem. The most unique
feature of the OnCell G3100 IP modem is that it makes linking legacy serial
devices to a cellular network easy. The
OnCell G3100 IP modem supports several advanced features, including Ethernet
Modem Mode, Reverse RealCOM Mode, Flexible Connection Mode, Standard TCP/IP
architecture, and I/O functionality. Ethernet Modem Mode
Ethernet Modem
mode is designed for use with legacy operating systems, such as MS-DOS, that do
not support TCP/IP networks. Connecting a properly configured OnCell G3100 port
to the MS-DOS computer's serial port allows you to use legacy software to
transmit data over the cellular network, even though the software was
originally designed to transmit data over a modem. This is accomplished by
converting dialed AT commands into IP format. Reverse RealCOM Mode
If your ISP can
only provide you with a private IP for your cellular connection, the IP address
could change frequently. In this case, the connection between the host and your
serial device will be offline until you can reconfigure the IP address in the
cellular IP modem. However, with "Reverse Real COM mode," the Moxa driver that
comes with the OnCell G3100 IP modem can establish a transparent connection
from the serial device to the host side by mapping the serial port to a local
COM port on the host computer. Flexible Connection Mode
The OnCell G3100
IP modem provides three types of connection mode for GSM/GPRS/EDGE: Always ON,
Inactivity Timeout, and Remote Host Recovered, providing users with greater
versatility, and helping to reduce your total operational costs. Standard TCP/IP Architecture
The OnCell G3100
IP modem comes with a full TCP/IP stack to make it easy to connect to the
cellular network. Three modes are supported: TCP Server, TCP Client, and UDP.
Whichever mode is used, once a connection is established, the two sides of the
connection can both send and receive data. I/O Function
The
2 digital inputs and 1 relay output built into the OnCell G3100 IP modem make
it unique among similar products on the market. The advantage to the user is
that system maintainers can be notified immediately if the Ethernet network or
power source gets disconnected. The OnCell G3100 IP modems can send out
warnings by e-mail, SNMP trap, or SMS, to allow prompt reaction to emergency
situations. Features
