Introduction
Tops CCC Products Co., Ltd. is providing new ways of connecting legacy serial devices to a
Local Area Network (LAN) or Wide Area Network (WAN). TCP/IP converters are
designed to operate serial ports over 10/100M Ethernet networks. The data is transmitted via
TCP/IP protocol. Therefore control is available via Ethernet, Intranet and Internet. TCP/IP
converters are packaged in a plastic case well suited for industrial environments. All serial
ports operate in common RS-232 mode , industrial RS-422 and RS-485 modes
configuration.
TCP/IP converter series is a low-cost, high performance design. By careful selecting high
quality with competitive prices components in the world, EX-9132 product made network
connectivity possible with affordable cost for virtually all kinds of devices.
The 8051 Series of TCP/IP converters consists of 2 models: EX-9132 (1 port for
RS-232/422/485) is a ready set product and the other EX-9132-M (1 port for
RS-232/422/485) is a module product for developing purpose by customers. This operation
manual will guide you step by step for the various functions of the TCP/IP converter.

Overview
TCP/IP converters are designed to make your serial devices Internet ready instantly.
8051 Series of TCP/IP converters makes them the ideal choice for connecting your
RS-232 or RS-422/485 serial devices—such as PLCs, meters, and sensors—to an
IP-based Ethernet LAN, making it possible for your software to access serial devices
anywhere and anytime over a local LAN or the Internet.
8051 Series converters 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. 8051 Series’ Virtual COM driver, software that works with COM
port 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.
8051 Series converters support manual configuration via the handy web browser console
and many protocols including TCP, IP, UDP, HTTP, DHCP, ICMP, and ARP. They are the
best solution to network your serial devices.

Block Diagram
Low-cost devices usually are equipped with low speed processors and limited memories. In
reality, they are neither having the capability nor practicality to manage complicated network
TCP/IP protocols. 8051 Series is a low cost while providing high performance network
solution by converting data stream between network TCP/IP and popular serial port signals.
In stead of processing TCP/IP packets directly, devices need only deal with those interface
signals, which greatly simplifies the complexity of TCP/IP network in linkage.

Product Features
□
□
□Data Conversion between RS-232/422/485 and Ethernet
Convert serial device (RS-232, RS-422, RS-485) data/signal into the TCP/IP package
data/signal and send them out with the Ethernet DataStream; or convert the TCP/IP
package data/signal into serial device data/signal.
□
□
□Digital I/O Activating (For OEM only)
Convert the sensors’ statuses into the TCP/IP package data and send them out with the
Ethernet DataStream; or use the TCP/IP package data to activate/deactivate the specified
digital outputs / inputs.

further information.
□
□

Converter Configuration
Initial IP Configuration
When setting up your converter for the first time, the first thing you should do is configure
the IP address. This chapter introduces the method to configure the device server’s IP
address. For more details about network settings, see “Web Console Configuration”. in
next sub section.
For quick and easy start , We suggest you to reference “Quick Installation Guide” manual.

Device Management Utility
On PC we provide a Device Management Utility named ExpertDAQETM which is an
executable program in Windows 32 bit environments. ExpertDAQETM Setup Tool is
used to detect and setup the installed converters. It uses UDP broadcast packets to
query and configure converters on the network.
When you activate the tool, it will detect the existence of the installed converters and
depict the converters’ status such as IP address, Subnet Mask, MAC Address, and
Device ID (see Figure 3.1). The Setup Tool only can setup one converter at a time.
Thus if there are more than one converter on the network, please shut down or
disconnect other converters. Otherwise the ExpertDAQETM can not detect the converter.
Other similar issues, you may reference to Q&A in Appendix A.
Due to the nature of broadcast UDP packets, ExpertDAQETM has following
characteristics:
□
□
□Broadcast packets aren’t limited by subnet. Even if the IP address of the converters
and the computer running ExpertDAQETM do not belong to the same subnet, it
still works fine.
□
□
□Broadcast packets can not pass routers. ExpertDAQETM can only be used to
monitor devices with computer running ExpertDAQETM in the same segment of
local area network

Refresh
Refresh the status. ExpertDAQETM will send another query to get updated
information.
Note: Always run the “View-> Refresh” after any data change.
Exit Exit from the program
ExpertDAQETM Config
Moving the mouse cursor onto the desired device that displaying in information window
Clicking the left button of mouse to invoke the ExpertDAQETM Config.

19
Note : Because ExpertDAQETM uses broadcast UDP packets, for the sake of
security, it allows configuration only when device's setup password is
empty.
Assign an IP Address with the same Subnet Mask of your computer, avoiding any
IP conflict with other network devices.
When you press [Setup] button, the IP address will be refreshed in 2~3 seconds.
