1Product Overview
1.1 Product Introduction
NPM301 is a high-performance embedded serial to Ethernet module. It can
implement self-adaptive 10Base-T/100Base-TX Ethernet port. Its serial port has
communication rate of 300 bps-115200bps and multiple operating modes like TCP
Server, TCP Client, TCP Auto, UDP and Real COM. It supports up to 4 connections
and other functions such as domain name visiting.
All settings of NPM301 module can be achieved through serial port and network. The
module can be used as a communication processor between serial device and PC, or
remote communication between multiple serial devices. It can be widely used in PLC
control and management, building automation, medical care automation system,
measuring instrument, and environment power monitoring system.
1.2 Product Function
Adopt 32-bit ARM processor
Support self-adaptive 10/100M Ethernet interface
Support AUTO MDI/MDIX, using crossed or cut-through network cable for
connection
Support 300bps-115200bps wire speed non-blocking communication
Support low power consumption mode and high performance mode.
Support multiple operating modes like TCP Server, TCP Client, TCP Auto, UDP
and Real COM driver. Operating port, destination IP address and port are all
configurable

2Product Features
TCP/UDP Direct Programmatic Access
NPM301 module supports TCP/UDP Ethernet direct access mode of standard API
interface form such as WINSOCK. It can implement all control and transmission
process through easy programming. In most cases, direct programmatic access,
which could achieve error-free connection, is the best solution.
Virtual Serial Port Access
For most serial devices based on serial port programmatic access, reprogramming is
not always the best choice. NPM301 module provides a virtual serial port access
mode. User only needs to install the driver that comes with the product, and then
multiple virtual serial ports would be created on PC. User software can transparently
access remote serial port device by opening the serial port virtualized by software and
need no complicate Ethernet access process. And all Ethernet control and
transmission process related to NPM301 module could be operated on the driver.
Interconnection of Two Serial Device Networking Servers
Sometimes user can extend serial port distance via Ethernet only. NPM301 module
supports this application, which is to implement point-to-point interconnection of two
devices through easy settings and no need of programming and drivers.
Multiple Hosts Sharing One Serial Device Networking Server
In many cases, multiple users need to share data resources from one serial port;
therefore, it needs multiple hosts to access one serial device networking server.

NPM301 module could operate in this mode according to user’s requirements,
allowing multiple hosts to access one serial port at different times.
One Host Accessing Multiple Serial Device Networking Servers
Because of the scattered distribution of collecting devices, it usually needs one host to
access multiple serial device networking servers in data collecting system. NPM301
module provides two modes to support this situation: one is establishing multiple
virtual serial ports for accessing different serial device networking servers respectively;
the other is using one virtual port to access all serial device networking servers. User
could reasonably choose those two modes according to their own features.
Support Cross-router Transmission
Routers are needed for connecting devices of both ends in many projects. NPM301
module could cross router to connect opposite device easily. The setup process is
quite easy as well.
