Low-cost devices are usually equipped with low speed processors and limited
memories. In reality, neither having the capability nor practicality to manage
complicated the TCP/IP network protocols. 8051 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 signal
which greatly simplifies the complexity of TCP/IP network in linkage.

Initial IP Configuration

When first setting up your converter, 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 settings network,
please see “Web Console Configuration” (In the next sub section).

For quickly and easier to start, we suggest you to refer to “Quick Installation Guide”

Device Management Utility of ETM

On PC we provide Device Management Utility named ETM.exe which is
executable program in Windows 32 bit environments. ETM 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 tool, it will detect 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, you have to temperately disable “WINDOWS Firewall”
function. After finishing setting the parameters, you can restart “WINDOWS
Firewall” function.

Due to nature of broadcast UDP packets, ETM has following characteristics:

□

□

□

Broadcast packets aren’t limited by subnet. Even if IP address of the
converters and computer running ETM do not belong to the same subnet, it
still works fine.

□

□

□

Broadcast packets can not pass routers. ETM can only used to monitor
devices with computer running ETM in the same segment of local area
network.

(Figure 3.1)

(Figure 3.3)

(Figure3.3)

20

Press ENTER or select [IP Address] in the [Config] menu, dialog will be
shown (see Figure 3.4).
Note: Because ETM uses broadcast UDP packets for sake of security, it
allows configuration only when device’s setup password is empty.

(Figure 3.4)

(Figure 3.4)

Assign IP Address with the same Subnet Mask of your computer, avoiding
any IP conflict with other network devices.
When you press [Ok] button, the IP address will be refreshed in 2~3
seconds (see the Figure 3.5).

(Figure 3.5)

can be set through HTTP protocol with popular browsers, e.g. Internet
Explorer, Netscape, etc. Setup converter as easy as surfing on WWW, no
special software will be required. Press [Alt] + [Enter] or select [Device

Settings] in [Config] menu, it will open new window in browser to
login the device. Alternatively, if IP address of converter already known,
