1. Getting to Know your BF-2300
1.1 Introduction
BF-2300 I/O controller is designed to make your industrial devices Internet monitor and control instantly.
The compact size of BF-2300 I/O controller makes them the ideal choice for connecting your devices to an
IP-based Ethernet LAN, making it possible for your software to monitor and control devices anywhere over
serial port (RS232 and RS485), a local LAN or the Internet.
BF-2300 I/O controller ensure the compatibility of network software that uses a standard network API
(Winsock or BSD Sockets) by providing TCP Server Mode, TCP Client Mode, and UDP Mode. And using
Chiyu’s virtual COM drivers, software that works with COM ports can be set up to work over a TCP/IP
network in no time. This excellent feature preserves your software investment and lets you enjoy the
benefits of networking your serial devices instantly.
BF-2300 I/O controller support automatic IP configuration protocols (DHCP, BOOTP) and manual
configuration via Chiyu’s web browser console. Both methods ensure quick and effective installation.
BF-2300 support special design for PPPoE + DDNS that could let your device to connect to Internet without
static IP address.

The following are the main features of BF-2300
TCP/UDP server/client support
The BF-2300 support three types of connection: TCP server, TCP client and UDP , user can select one of types
to meet application requirement.
DHCP Client
DHCP (Dynamic Host Configuration Protocol) client obtains the TCP/IP configuration at start-up from a
centralized DHCP server, which means it can get IP address, an IP default gateway and DNS server.
PPP Over Ethernet
PPPoE is a protocol for connecting remote hosts to the Internet over DSL connection by simulating dial-up
connection.
Dynamic DNS
With dynamic DNS support, you can have a static hostname alias for a dynamic IP address, allowing the host to
be more easily accessible from various locations on the Internet.
Auto-negotiating 10/100Mbps Ethernet
The Ethernet interface automatically detects if it is on a 10 or a 100 Mbps Ethernet.
IO Remote Control
The BF-2300 provides command protocols to integrate into customer’s software via TCP/IP connection to
monitor or control customer’s device.
Alarm Generation
With SMTP client support, you can set system to trigger alarm message via E-Mail or SMS (Short Message
System) to your mobile phone.
Full Network Management via Web
This feature allows you to access or manage device through IE or Netscape on any platform. The firmware also
can be upgraded via Web browser.
Backup and Restore configuration
This feature allows you to backup system configuration to a file and restores it, for the security issue, the file
which backup from system is an encryption format.
Firmware Upgrade
BF-2300 support two ways of firmware upgrade: one is through Web browser such as IE or Netscape, another is
through Xmoden protocol.

2.3 Initial Setup
Use this section to set up your computer to assign it a static IP address in the 192.168.0.1 to 192.168.0.254
range with a subnet mask of 255.255.255.0. This is necessary to ensure that your computer can communicate
with your BF-2300.
Your computer must have an Ethernet card and TCP/IP installed. TCP/IP should already be installed on
computer using Windows 98/2000/XP and later operating systems.
Note: Connect a computer to BF-2300 Ethernet port directly should be with crossover Ethernet cable, if
both connect to hub/switch should be with straight-through Ethernet cable.

2.3.1 Installing the TCP/IP Protocol
If you are not sure whether the TCP/IP Protocol has been installed, follow these steps to check, and if necessary,
install TCP/IP onto your PCs.
Step 1：Click the “Start” button. Choose “Settings”, then “Control Panel”. Double-click the “Network
Connections” icon. Your Network window should appear as follows:
Step 2：
For Windows 98 and Millennium
On the “Configuration” tab (if using Windows 98 and Millennium PCs), select the TCP/IP line for the
applicable Ethernet adapter. Do not choose a TCP/IP entry whose name mentions
PPPoE, VPN. If the word TCP/IP appears by itself, select that line. Click the Properties button.

Step 6：After a few seconds, you will be returned to the Network window. The TCP/IP Protocol should now be
on the list of installed network components (see 3 above).
2.3.2 Fixed IP Addresses Configuration
For Windows 98 and Millennium
Step 1：To set up computers with fixed IP Addresses, click the “Properties”button. The TCP/IP Properties
window consists of several tabs. Choose the “IP Address” tab as shown below.
Step 2：Select “Specify an IP address” and enter “192.168.0.xxx” (the default value of BF-2300 is
192.168.0.125) in the “IP Address” location (where xxx is a number between 1 and 254 used by the
High-Performance BF-2300 to identify each computer), and the default “Subnet Mask” “255.255.255.0”. Note
that no two computers on the same LAN can have the same IP address.

through Intranet or Internet.
3.1 Network setting
The BF-2300 support three IP connection types: Static IP, DHCP and PPPoE. These types are listed in the
drop-down menu for the IP Configuration setting. Each setup screen and available features will differ depending
on what kind of IP connection types you select. Default is Static IP
Static (or Fixed) IP

Primary DNS
Setting Factory Default Necessity
E.g., 168.95.1.1 168.95.1.1 Optional
The Domain Name System (DNS) is the way that Internet domain names are located and translated into Internet
Protocol (IP) addresses.
When the user wants to visit a particular website, the computer asks a Domain Name System (DNS) server for
the website’s correct IP address, and the computer users the response to connect to the web server. DNS is the
way that Internet domain names are identified and translated into IP addresses. A DNS server is a host that
translates this kind of text-based domain name into the numeric IP address used to establish a TCP/IP
connection.
If you are connecting through a static or fixed IP from your network environment, perform these steps：
Step 1: Enter IP address
Step 2: Enter Subnet mask
Step 3: Enter Gateway IP address
Step 4: Enter Primary DNS IP address
Step 5: click Apply button

If there is a DHCP Server existing in your network environment or you subscribe a CABLE service from your ISP,
you can set IP configuration to DHCP to get a dynamic IP address. The Host Name is an optional item,
depending on your DHCP Server setting.
Note 1: to gain CABLE service, you also need to change the MAC address of BF-2300 to the MAC
address of register in ISP. Please refer to Chapter 4 Device Admin/Mac Address Change
