Block Diagram
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. ARM-7 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 simplifies the complexity of TCP/IP network in linkage.

When you finish the steps mentioned above and LED indicators as shown,
the converter installed correctly. You can use the Setup Tool “ETM.exe” to
setup IP Address.
For setup proceed the advanced parameters, please use web browser (IE or
Netscape) to continue the detailed settings.

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

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 configure 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 finishing 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 fine.
□
□
□
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.
