1.2 Usage ipEther232 (virtual ComPort)

ipEther232 enables you to use serial interfaces via a TCP/IP

network, LAN oder WAN.

This allows you to control devices without a network interface

over long distances.

Such devices are:

• modems

• printers

• SPS controls

• embedded controllers

Integration in the Windows environment is realized via a driver

which supplies a virtual serial "COM" interface.

Aus Sicht der Applikation sehen die virtuellen COM-Schnittstellen

wie lokale, im PC eingebaute, Schnittstellen aus. Auch das

Verhalten der Schnittstelle entspricht weitestgehend dem einer

physikalischen COM-Schnittstelle. An einem PC können bis zu

255 virtuelle Schnittstellen installiert werden.

1.3 Usage ipEther232.Modem (Ethernet modem)

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 controllers

ö Counting devi ces

Such devices are: ö Embedded controllers

ö Industrial 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 st i 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

• si m pl e integration of seri al appli cations

"Networking" w ill soon be the global standard. How ever, manufacturers

require expensive labor, precious time and comprehensive experience to

develop netw ork technologies. As most devices are already equipped w ith

an RS232/485 interface, the Ethernet modem offers an instant and efficient

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.

1.4 Usage ipEther232.PPP (PPP – Gateway)

The PPP / Ethernet – Converter enables the transmission of network packets via

a serial interface from and to the Ethernet (PPP = Point to Point Protocol).

With ipEther232.PPP all these (serial) devices can be linked up to an Ethernet

LAN via TCP/IP and thus also to the internet or your company intranet.

The PPP gateway solution works with all operating systems and is compatible

with existing PPP applications. You can start several services (ftp, telnet, www,

ssh, rsh, rcp etc.) simultaneously via this transparent network connection.

1.) „Ethernet for all“

Ethernet capability for all TCP/IP

enabled devices w ithout a dedicated

Ethernet interface, such as:

- Embedded PC

- SPS

- PC

- Notebook

- Modem

- Router

- Pa l m

2.) „simple Network routing“

Simple routing betw een two

netw orks via GSM, ISDN or analog

modems, for instance to link up a

branch to the company LAN.

3.) „dial in“

Enables company LAN access for

home office, remote maintenance or

for field reps.

1.5 Usage ipNTP (SNTP Timeserver)

The ipNTP Standalone Timeserver can transmit DCF77 / GPS time information

onto computers, controllers or other dynamically critical devices / applications

over the ethernet. The client first determines the messial transmission time for the

data exchange with the time server. After that the client fetches the current time

and patches this value around the transmission time. The time on the client

deviates then only a few milliseconds from the timeserver.

All components in the TCP / IP network could be synchronized over the SNTP

protocol with the time signal transmitter Mainflingen near Frankfurt at the Main

(DCF77), or through the global satellite navigation system (GPS).

Time-precise solutions are needed in task executions, schedulers, personnel

information systems, time recordings and error logging. Through the commitment

of the network protocols SNTP (Simple Network Time Protocol – RFC 2030) and

TCP / IP is the platform independence even in heterogenous networks

guaranteed.

NTP Server - Information

The network time protocol (NTP) is used in order to synchronize the time of a

client over the Internet/Intranet with other computers or with an external clock.

The primary NTP timeservers are over external timers locked maximally exactly

to the Coordinated Universal Time (UTC). The NTP Client synchronize the time

with NTP commands with the servers indicated as an argument.

DCF77 - Information

The DCF77 radio clocks receive the official time of the federal republic of

Germany from the physical-technical federal institution (PTB) in Braunschweig

and transmit the signal over different interfaces to computers and systems. The

long-term accuracy of the PTB calibrating standard measure is achieved by radio

alignment of the sender DCF77 in Mainflingen at Frankfurt/Main of 1 x10 E-13

weekly. Due to the high accuracy only this time is recognized as legally binding in

the federal republic.

GPS - Information

In approx. 20.000 km high satellites are moving on different railroads around the

earth. In every satellite is a nuclear clock (min. accuracy 1x 10 E-12), whose time

is send out continuously with the orbital data. The GPS-receiver registers the

dates of a minimum of 3 and maximum of 6 satelites and calculates his position

from these values. If the position is computed, the terms of the dates can be

determined by the individual satellites. From these values the GPS world time is

determined in the timeserver and continued about a variable quartz time exactly.

Chapter 2: Commissioning the ipEther232

2.1 Installation

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 driver set-up program and the configuration tool.

The driver runs on all Windows NT based operating systems, therefore Windows

NT with SP5, Windows 2000 and Windows XP.

No PC reboot is necessary after installation. The configuration tools starts

automatically after installation.

For later configuration sessions the program is included in the "Program files -

ipcas GmbH – ipEther Products“ folder.

2.2 Configurationtool

The configuration program recognizes all devices in its own network segment,

even if they do not have a valid IP address.

By clicking on a column in the overview border (e.g.: “IP Address”) all found

devices are sorted for a better overview.

Änderu nge n vorbe halte n Stand 31.08.0 4

ipcas GmbH ipEther232 V10.21 Seite 17 von 98

In the overview border are the following entries:

ID Device-id

Name Info (Comments could be very helpful to find a

particular device very quickly)

Info Current configured ComPort (only at ipEther232

„virtual ComPort“)

IP Address Current IP-Address

MAC MAC-Address

Dev ice Type Firmwaretype of the device

Version Current Fi rmwareversion

In Use If this entry is „True“, the device is already in use and

you shouldn`t configure the parameters.

Passw ort required If this entry is „True“, the device is password-

protected and the password have to be entered

before the configuration. (Right-click “Login”)

If the passw ord is forgotten, the device must be

returned.

Logged in If this entry is „False“, the password (Right-click

„Login“) have to be entered before the configuration.

Ping OK If this entry is „False“, the device couldn`t be found. It

is not connected, switched of or is in another network

segment.

in local Net If this entry is „False“, the device is not in the local

network segment.

If the device is installed behind a router, the IP-

Address couldn`t be changed. This prevents that a

device is getting inaccessible by mistake.

T o start wi th, each device must be al located an unambi guous IP address.

On delivery of ipEther232 no valid IP-Address has been set (Default: 10.10.5.1).

The IP-Address can be obtained from the network administrator. It must comply

with your network and cannot be assigned twice.

If you are embedded in a DHCP network, you`ll have to recieve a static

IP-Address from your network administrator for your ipEther232.

In order to set the IP address in your ipEther232, the device must be connected

to its own network segment.

If need be, connect the device via a "cross over“ cable to the PC.
