Low-cost devices usually are equipped with low speed processors and limited memories. In reality, they are neither having capability
nor practicality to manage complicated network TCP/IP protocols. EP-132 Series is 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 simplies the complexity of TCP/IP network in linkage.

Converter Configuration
Initial IP Configuration
When setting up your converter for rst time, the rst thing you should do congure the IP address. This chapter introduces of method to
congure the device server IP address. For more details about network settings, see “Web Console Conguration” in next sub section.
For quick setup of converter, we suggest you reference the “Quick Installation Guide.”
Device Management Utility of ETM
On PC we provide Device Management Utility named
ETM.exe which an executable program in Windows 32 bit
environments. ETM Setup Tool used to detect and setup
the installed converters. It uses UDP broadcast packets
to query and congure converters on the network.
When you activate the tool, it will detect the existence
of installed converters and depict the converters status
such as IP address, Subnet Mask, MAC Address and
Device ID (see Figure 3.1).
If your computer OS is Windows XP version which means
“WINDOWS Firewall” function in OS activated. However
ETM.exe wouldn’t detect the converter IP address,
therefore, you have to temperately disable “WINDOWS
Firewall” function. After nishing the parameters settings,
you can restart “WINDOWS Firewall” function.
Due to nature of broadcast UDP packets, ETM has following characteristics:
• Broadcast packets aren’t limited by subnet. If even IP address of converters and computer running ETM do not belong to same
subnet, it still works ne.
• Broadcast packets can not pass routers. ETM can only be used to monitor devices with computer running ETM in same segment
of local area network.
Menu “View”
• View -> Refresh F5: Refresh the status. ETM will
send another query to get updated information. (See the
Figure 3.2.)
Note: Always run the “View-> Refresh” after any data
change.
• View -> Exit Alt+F4: Exit from the program (see Figure 3.2).

• Press ENTER or select [IP Address] in the [Cong]
menu, a dialog will be shown (see Figure 3.4).
Note: Because ETM uses broadcast UDP packets for
sake of security, it allows conguration only when
setup the device password is empty.
Assign IP Address with same Subnet Mask of your
computer, avoiding any IP conict with other network
devices.
• When you press [Ok] button, IP address will be
refreshed in 2~3 seconds. (See the Figure 3.5.)

• Password (Setup Login): This eld is administration password for authentication. Factory is default “empty”. However, it is not
recommended to leave empty in eld operation. If you could not login, it means you have to key the password. If you do not know the
password you can turn off the power and then use any point tip to press “Reset” button and hold it to turn on the power. The password
will be reset to the factory default as “empty”.
EP-132 TCP/IP converter uses the same password protection mechanism commonly used 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 a correct password, login will not proceed. This prevents intruder from nding the password by computer generated program.

no any data transferred (send / receive) within dened timeout period (1 to 99 minutes), then it 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 t different kinds
of application.
• Packet mode of serial input: Packet mode could be in enabled/disabled mode. If packet mode enabled, data input from UART will
be deferred until input buffer full or converter detects 10-character packet gap and no more character arrived. The block waiting time
extended to avoid the splitting of complete packet.
