Block Diagram
Low-cost devices usually are equipped with low speed processors and limited
memories. In reality, they have neither the capability nor practicality to manage
complicated network TCP/IP protocols. The ARM Cortex™-M3 32-bit processor
has been specifically developed to provide a high-performance, low-cost platform
for a broad range of applications including microcontrollers, automotive body
systems, and industrial control systems, networking by converting data stream
between network TCP/IP and popular serial port signals.
Instead 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. The ARM Cortex-M3 processor provides outstanding computational
performance and exceptional system response to interrupt while meeting low cost
requirements through small core footprint, industry leading code density enabling
smaller memories, reducing pin count, and low power consumption.
The central core of ARM Cortex-M3 processor, based on a 3-stage pipeline
Harvard bus architecture, incorporates advanced features including single cycle

6
multiply and hardware divide to deliver an outstanding efficiency of 1.25
DMIPS/MHz. The ARM Cortex-M3 processor also implements the new
Thumb®-2 instruction set architecture, which combined with features such as
unaligned data storage and atomic bit manipulation delivers 32-bit performance at a
cost equivalent to modern 8- and 16-bit devices.

Connect the serial data cable between the converter device and the serial devices.
Follow the parameter setup procedures to configure the converter (see the following
chapters).
Digital I/O
Through EX-9132C-2RS485 , D I/O can transform the status of sensor into the
TCP/IP package data and send out by Ethernet Data Stream (The
EX-9132C-2RS485 must indicate the IP address and COM Port) or activate the
indicated Digital output (Remote WinSock must indicate the EX-9132C-2RS485).
Connect the data wires between the EX-9132C-2RS485 and the
RS232/RS-485/RS-422 device. Follow the parameter setup procedures to configure
the converter (see the following chapters).

adapter is part of the packaging. Connect the power line to the power jack at the left
side of EX-9132C-2RS485 TCP/IP converter device and put the adapter into the
socket. If the power is properly supplied, the “SYS” red color LED will be on..
Ethernet LAN Port
The connector for network is the usual RJ45. Simply connect it to your network
switch or Hub. When the connection is made, the LAN LED indicator will light up.
When data traffic occurs on the network, red PORT LED indicator will blink during
data transferring and receiving.
Reset Button
If by any chance, you forget the setup password, or have incorrect settings making
TCP/IP converter inoperable. First, turn on the power. Second, use any point tip to

EX-9132C-2RS485 Converter Configuration
Initial IP Configuration
When sett up your converter for the first time, the first thing you should do is to configure
the IP address. This chapter introduces the method to configure the device server’s IP
address. For more details about network settings, please see the Network Settings section
in Chapter3, “Web Console Configuration”.
The following topics are covered in this chapter:
□

□
Device Management Utility
□
□
□
EXBrowser “View”
□
□
□
EXBrowser “Modify IP”
□
□
□
EXBrowser “Modify MAC”
Device Management Utility
Note:EXBrowser also can use on EX-9132C-2RS485
On PC we provide a Device Management Utility named “EXBrowser.exe” which is an
executable program in Windows 32-bit environments. EXBrowser setup tool is used to
detect and setup the installed converters. It uses UDP broadcast packets to query and
configure converters on the network.

17
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 EXBrowser.exe can not detect the converter.
Due to the nature of broadcast UDP packets, EXBrowser has following characteristics:
□
□
□Broadcast packets are not limited by subnet. Even if the IP address of the converters
and the computer running EXBrowser that do not belong to the same subnet, it still
works fine.
□
□
□Broadcast packets can not pass routers. EXBrowser can only be used to monitor
devices with computer running EXBrowser in the same segment of local area
network.
Note:EXBrowser also can use on EX-9132C-2RS485
(Figure 3.1)

EXBrowser “View”
□
□
□View -> Refresh
There are two ways for refreshing the status of existing devices. You may
select the item “View” to refresh the status of existing devices on LAN.
Another is to click the icon as red color remark as below. EXBrowser will send
another query to get updated information. (see Figure 3.2).
Note: Always run the “Refresh” after any data change.
(Figure 3.2)
□
□
□File -> Exit Alt+F4
Exit from the program (see Figure 3.3).
(Figure 3.3)
EXBrowser “Modify IP”
□
□
□Modify IP -> Dialog Frame
To click the device on the existing devices list in the EXBrowser table and then the
function bar will be enable. To press second icon of “Modify IP” on function bar
and a dialog frame table will be shown (see Figure 3.4).

19
(Figure 3.4)
Assign an IP Address with the same Subnet Mask of your computer, avoiding any
IP conflict with other network devices.
When you press “Confirm” button, the IP address will be refreshed in 2~3 seconds.
(Figure 3.5)
After click “Confirm” button and then “Input Password” request will be pop-up on
screen (see Figure 3.5). Please simply press “Confirm” button and the new device’s
IP will be changed and save in table, if you changed it.
