Make Your Serial Devices Internet Ready™
In the automation industry, tens of millions of sensors,
gauges, PLCs, card readers, and other devices must be connected to form a
control network and provide managerial data for information systems. The
most widely used interfaces for connecting such devices are RS-232 and
RS-422/485.
In recent years, network infrastructures such as
Ethernet and Internet have received wide recognition in the automation
industry. The trend has been towards adopting a mature, open technology,
such as TCP/IP and Ethernet, for controlling serial devices. Device
manufacturers and device users are both looking for an instant solution to
transform and connect devices to the Ethernet/Internet.
MOXA NPort Express provides just such an INSTANT
solution, giving you a way to link traditional devices that have an
RS-232/422/485 interface with the Ethernet/Internet.
How to Make Your Serial Devices Internet Ready™
INSTANTLY
To change a serial device into a network-enabled device
can take much time and effort, considering the development and integration
required for the CPU, DSP, TCP/IP protocol, and real time operating
system.
But now it is no longer necessary to invest extra
manpower on TCP/IP and Ethernet development. MOXA NPort Express provides
off-the-shelf solutions that utilize a serial device’s existing
RS-232/422/485 port and make your devices Internet ready INSTANTLY.
MOXA provides two ways to bring this about
External Solution: NPort DE-311/211
This is a 1-port device server that’s designed to convert data from the
RS-232/422/485 interface to a form suitable for 10/100 Mbps TCP/IP
Ethernets.
Check out our Embedded Solution: NPort DE-311M
This is an RS-232/TTL to Ethernet, board-level OEM product that device
manufactures can easily integrate into their products.
Applications
- Intrance control and security/attendance management
- Manufacturing automation
- Telecom and fiber optic network management
- Industrial control and process control

How a PC uses NPort Express to Access Serial Data
Two approaches are available to access serial data:
Driver Access
By using Moxa's NPort Native COM driver, NPort Express's
serial port can be set up to emulate a remote COM port. In this case,
there is no need to modify software or communications objects. The
solution can be used immediately with NPort Express's serial port, and is
applicable to all Windows platforms, as well as Linux/Unix systems that
have driver support.
Socket Access
Use TCP/IP sockets to access serial data via a specific
NPort Express TCP port. This solution is applicable to any system that has
TCP/IP connectivity. In addition, MOXA provides several operation modes
and features that use socket access, such as:
- TCP Server: allows passive TCP connections for your
serial device
- TCP Client: actively sends serial data to the network
- UDP Server/Client: provides UDP based fast data
packet transmission and multi-destination data transmission for serial
devices
- Ethernet Modem: provides NPort Express with AT
command simulation, for use with legacy DOS software over an Ethernet
- Pair Connection: provides data tunneling over an
Ethernet, for use with any type of serial device
- Data Packing: the data packing facility inhibits data
segmentation
