Chapter 1: The Device
1.1 Usage
ipEther232.Modem enables you to use serial interfaces via a TCP/IP network. .
This allows you to control devices without a network interface over long
distances. In addition to the serial interface, the Ethernet modem also has a
network interface. In order to connect two serial devices simply use two modems
linked via Ethernet instead of a serial cable.
ö Terminals
ö CNC controlle rs
ö Co un ti ng de vi ces
Such devices are: ö Embedded controllers
ö Industri al switches
ö Serial printers
ö SPS controllers
ö Card scanners
ö Measuring equipment
ö UPSs
Thus all applications and devices that support terminal or modem functionalities
can also be used via the Ethernet. This has numerous advantages:
· lower telephone costs
· reduce the number of analog connections (monthly fee)
· si m pl ifie d lo gi sti cs
· extremely low porting costs
· protects your investments by converting serial devices into network
devices without necessitating changes in the existing software, saving
additional product development costs
· versatile power supply and optimal housing solutions
· serial devices can be used by several clients
· automatic setup of network connection after interruptions
· easy to setup and suitable for larger installations
· simpl e integ ration of se ri al ap pli cations

"Netw orking" w ill s oon be the global standard. How ever, manufac turers
require expensive labor, precious time and comprehe nsive experience to
develop netw ork technologies. As most devices are already equipped w ith
an RS232/485 interface, the Ethernet modem offers an instant a nd ef f icient
solution for transmitting RS232/485 data via the netw ork. The Ethernet
modem not only provides added value to your product, it also adds to the
value of your existing equipment for the next generation.

connection to a PC. Fast flashing indicates that the
device is in use.
· LINK LAN There is a physical link to the network.
· LAN Rx Packets are received via the Ethernet.
· LAN Tx Packets are sent to the Ethernet.
· V24 Rx Data is received via the RS232 line.

Chapter2: Commissioning the ipEther232.Modem
2.1 Commissioning
Connect the device to the mains. The "Power" signal and the flashing "System"
LED indicate that ipEther232 is ready for operation.
ipEther232 is connected to the network via an RJ45 socket.
The "Link LAN" LED (connection) indicates the connection to the LAN.
If this is not the case, check the netwok connection or network line.
The enclosed CD contains a modem driver set-up program and the configuration
tool. The modem driver runs on all windows NT based operating systems, as well
as Windows NT 4 from SP5, Windows 2000 and Windows XP.
No PC reboot is necessary after installation. The configuration tool for configuring
the device starts automatically after installation.For later configuration sessions
the program is included in the "Programme-ipEther232.Modem" folder.
You can also set up your ipEther232.Modem with a serial configuration using AT
commands.
(for more details see chapter 2.6 Serial Configuration and chapters 3 & 4).
2.2 Set the IP Address
On delivery of ipEther232, no valid IP address has been set (Default: 10.10.5.1).
T o start wi th , each d e vi ce must b e allocat e d an un am bi gu ou s IP ad d re ss.
The IP address can be obtained from the network administrator. It must comply
with your network and cannot be assigned twice.
In order to set the IP address in your ipEther232, the device must be connected
to its own network se gment. If need be, connect the device via a "cross over"
cable to the PC.
The configuration program recognizes all devices in its own network segment,
even if they do not have a valid IP address. Double-click on the device entry to
call up a dialog, where you can enter a valid IP address and further
configurations.

The entry "Stat e " has the follow ing meaning :
· "not found"
The device could not be located anymore. It is not connected, switched off or
has been connected after a router blocking the UDP Port 3497.
· "connected"
The device has been located and can be addressed via the entered IP
address.
· "connected via router"
The device has been located and installed after the router. The IP address
cannot be changed.
· "found but unreachable"
The device has been located in the own network segment, but could not be
accessed via the entered IP address. Check whether the entered IP address
is valid for your network.
· "in use"
The device is in use at the moment. The parameters cannot be changed.
· “access denied“
Access wa s denied because password authentication has failed.
If ipEther232s are connected after a
router, they are not automatically
located. They have to be entered
manually ("Add Device manually“).
This is done by entering their IP
address. If the device can be
accessed via this address, it is
included in the list.
If the device is installed after a
router, the IP address cannot be
changed. This prevents the device
from becoming inaccessible by
accident.

2.3 Configuration
As mentioned above, the configuration program recognizes all devices in its own
network segment.
Double-click on an entry to open the detailed five-part dialog.

TCP/IP:
This tells you the device ID, i.e. the ipEther232.Modem serial number and this is
where the network settings are configured.
Modem settings:
Here you can define the modem behavior.
"Connect to IP": Enter the IP address of the "communication partner" where a
connection is to be set up automatically (Leased line). After a connection breakoff there is an automatic attempt at restoring the link.
"Answer incoming calls": automatic call accept.
"Echo": command echo on.
"Quiet Mode": Re sult co de s on.
"Ignore DTR": ignore DTR status change.
RS232:
Baud rate, databits, parity and stopbits are adjusted to the communication
behavior of the serial terminal device.
"Total Timeout": The default value of 50 ms applies to most cases. The "ping" tool
assist s in determining the ideal throughput time (see below).
"Character Distance" with a default value of 5 ms requires adjusting only in very
rare cases.
Throughput time + 10ms = ideal “To tal Tim eou t“
here < 10ms + 10ms = 20ms

TC 57 se ttings:
The advantage of the TC 57 settings is that on reception of a frame of this
format (from the RS232 line) the frame is immediately sent on to the Ethernet
without having to wait for a timeout. This greatly improves communication speed
and performance.
The IEC 60870-5-1 and IEC 60870-5-2 norms define four standard frame
formats for the link layer. They are:
· Format FT 1.1
· Format FT1.2
· Format FT 2
· Format FT 3
The transmission frame formats - FT 1.2, FT 2 and FT 3 have a Frame of fixed
length.
The Frame with variable length for FT 2 and FT 3 have a header of fixed length.
It includes “Start character”, “Length” byte, “User Data” and “Check sequence”.
The user must select the desired Format and include values for “Fixed frame
length” and “Header length” parameters.
The range of “Fixed frame length” is from 2 to 255 bytes.
The range of “Header length” is from 2 to 14 bytes.
Firmware:
This tells you the firmware release. You can update to the most current version.
