Chapter 1: Introduction
Section 1. Features
NET101 is one of the smallest RS232/RS422/RS485 Ethernet Converter in the
market. This device provides the means to transfer serial data over the Internet
without having to make changes to your existing hardware/software. That is done by
connecting two NET101 in Master mode and Slave mode. Alternatively, a virtual
driver can be installed to control the facility over Internet.
The NET101 also could be used as a MODBUS gateway. It could convert transaction
between the MODBUS on Serial Bus and MODBUS on TCP/IP. Please refer to the
specification of MODBUS for detailed specification on MODBUS.
Some of the main features of this device are;
Firmware:
•Built-in Web Server
•Support RS232 / 422 /485 (Half/Full Duplex) physical bus
•Auto-detection of Ethernet bus type
•Support Virtual COM port drivers from Microsoft Windows platform
•Support One-on-One communication mode
•Support Virtual COM port mode
•Gateway between MODBUS Serial and MODBUS on Ethernet
•Configuration via telnet, Web or Netility (freeware)

Section 2. Networking with NET101
NET101 gives the user two options when it comes to Network connection. The user
may choose to manage and control the various serial devices over Internet using
windows Virtual COM port function (refer to Fig 1). In this configuration, a NET101 is
connected to a serial device. The user can then manage and control each of these
serial devices over LAN.
Fig.1 NET101 using a Virtual COM Port in Windows mode
To extend this further, the user may opt to have a One-on-One configuration (refer to
Fig. 2). One of these 2 NET101 needs to be configured in Master mode, and the other
is configured in Slave mode.
