Neport-485资料下载（英文）

The NePort™-485 is the most compact, integrated
solution available to web-enable any device with an
RS-422 or RS-485 serial interface. By simply adding
NePort-485 to a product design, device manufacturers
cut their design cycle by as much as 80% and are able to
offer Ethernet connectivity in record time.
The NePort-485 is configurable for either RS-422 4wire
or RS-485 2-wire communication. It supports multi-drop
RS-485 networks by providing a logic level serial
interface designed to connect directly to an RS485
transceiver chip. In the RS-485 2- wire mode, one of the PIO
pins supplies the necessary transmit enable signal.
The NePort-485 offers the highest level of integration
available in a device server. Within a compact RJ45
package is a 32bits RISC, 10/100 Ethernet transceiver,
high-speed serial port, status/diagnostic LEDs, and 3
programmable I/O pins. In the space that is normally
consumed by a connector, the NePort-485 provides a
complete networking interface.
To enable access to a local network or the Internet, the
NePort-485 integrates a fully developed TCP/IP network
stack and robust RTOS. The NePort-485 also includes
an embedded web server used to remotely configure,
monitor, or troubleshoot the attached device.
Where there’s a need for custom user interfaces and a
desire to use common and familiar tools, the NePort485
can serve web pages to a web browser. The NePort-485
becomes a conduit between you and your device over
the network or Internet.
The Windows™-based configuration software,
DeviceInstaller, simplifies installation and setup. The
NePort-485 can also be set up locally through its serial
port, or remotely over a network using Telnet or a web
browser. Flash memory provides for maintenance-free
nonvolatile storage of web pages, and allows future
system software upgrades.
Using our highly integrated hardware and software
platform, you will add profit to your bottom line by
significantly reducing product development time, risk,
and cost.
