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.
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. 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.
External Solution: NPort Express
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.
Embedded Solution: NPort Express Module
This is an RS-232/TTL to Ethernet, board-level OEM product that device
manufactures can easily integrate into their products.
Applications
- ntrance control and security/attendance management
- Manufacturing automation
- Telecom and fiber optic network management
- Industrial control and process control
- Hospital/Laboratory automation
- Remote image transmission
How a PC uses NPort Express to Access Serial Data
Two approaches are available to access serial data:
Driver Access
By using 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, several operation modes and features that use socket access are
provided, such as:
- CP 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
