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. ARM-7 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.

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

20

Refresh

Refresh the status. ExpertDAQETM will send another query to get

updated information.

Note: Always run the “View-> Refresh” after any data change.

window

Clicking the left button of mouse to invoke the ExpertDAQETM Config.

21

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.

22

Web Console Configuration

In addition to basic IP address and subnet mask, specific device settings

can be set through HTTP protocol with popular browsers, e.g. Internet

Explorer, Netscape, etc. Setup of the converter is as easy as surfing on

WWW, no special software will be required. Press [Alt]+[Enter] or

select [Device Settings] in the [Config] menu, will open a new window
in browser to login into the device. Alternatively, if the IP address of the

converter is already known, you can connect to the converter directly by

providing its IP address in the URL field of browser.

to press “Reset” button and hold it to turn on the power. The password will
be reset to the factory default as “empty”.

EX-9132-2 TCP/IP converter uses the same password protection

mechanism commonly used in Windows NT or UNIX. If there are more than
“3 consecutive failures” in password check during login, the login function
will be disabled for “15 minutes”. During this 15 minutes period, if you

supply correct password, login will not proceed. This prevents intruders from

finding the password by computer generated program.

we add a mechanism - "inactive timeout" to identify whether the socket is

active or dead. If there is no any data transferred (send / receive) within the

defined timeout period (1 to 99 minutes), then it is probably a dead

socket, and the socket will be closed automatically, thus a new connection

can be accepted again. The timeout period can be set by users to fit different

kinds of application.

□

□

□

Packet mode of serial input

Packet mode could be in enabled/disabled mode. If packet mode is enabled,

the data input from UART will be deferred until the input buffer is full, or the

1. Log in the web page.

2. Press the reset button of the converter.

3. Select the update button.

4. After Tx & Rx light flashing then unclasp the reset button.

5. The password will reset to the factory default. ( empty )

33

Self-Testing

After completing the wiring and parameter setting, we should verify if the
setting is correct or not. This chapter will introduce how to use a single
computer to test if the converter behaves well.

The operating system can be Windows 95, 98, ME, XP, 2000. The “Hyper
Terminal” utility should be installed on your PC (see Figure 4.1). It can be
found in your Windows installation CD.

The wiring architecture is similar to “RS-232 Wiring” in chapter 2, and the
“Serial Device” is replaced by the PC’s COM 1. The same PC also plays
the roll of the Remote Host.

34

Hyper Terminal for TCP/IP WinSock

Initiate a Hyper Terminal from the Start Menu in Windows (see Figure 4.1),

give a terminal name, choose an icon, and press “OK” button (see Figure

4.2).

(Figure 4.1)

(Figure 4.2)

35

Select “TCP/IP(Winsock)” option at the “Connect using:” field (see Figure

4.3)

.

(Figure 4.3)

After “OK” button is pressed, Figure 4.4 appears. Enter the converter’s IP

address (e.g. 192.168.0.10) at the “Host address:” field, and the Socket port

number set for the Serial Port 1 at the “Port number:” field (e.g 4660). (The

Socket type of the Serial Port 1 should be “TCP Server”.)

(Figure 4.4)

36

After “OK” button is pressed, Figure 4.5 appears. If the Hyper Terminal

connects with the converter successfully, the time clock at the “left lower”

corner “Connected hh:mm:ss” will start counting.

(Figure 4.5)

37

Hyper Terminal for COM Port

Initiate another Hyper Terminal as a COM Port Terminal (in Figure 4.3,

select COM 1 or other COM port instead of “TCP/IP (Winsock)”). Set the

COM port Properties to be the same as those set for the Serial Port of the

converter ( 9600.N.8.1 ).

(Figure 4.3)

Data Transmission

When all steps described above are finished, type any characters on the

COM Port Terminal and check if the typed characters are also displayed on

the TCP/IP Winsock Terminal. Alternatively, check if the characters typed

on the TCP/IP Winsock Terminal are also displayed on the COM Port

Terminal. If yes, then all settings are correct and the converter can operate

properly.
