Ethernet Modem - ipEther232.Modem
|
|
Network replaces phone line
Many devices require a modem (e.g. dial-up modem) coupled to the RS232/485 interface to enable communication via telephone extension. Long distances and longer dial-up times could make this very expensive. However, the ipEther232.Modem ( Ethernet modem Fig. 1) allows you to independently connect all these devices to an Ethernet network and therefore to the Internet or your in-house Intranet via TCP/IP. Users can thus address the devices from different workstations regardless of their location.
|
The ipEther232.Modem consists of an operating system-independent solution compatible with existing modem applications. To activate a connection, 2 Ethernet modems are required. Figure 2 illustrates an example of network communication.

The Advantages
Fig. 2: Network connection example |
Major ipEther232.Modem advantages:
- No phone costs for dial-up modems
- Existing network infrastructure can be used
- Previous modems are replaced
- No phone port necessary
- Internet and Intranet access is possible
- Compatibility with existing modem applications
Different modes are available:
| Dial-up |
 |
Connection on demand |
| Leased line |
|
Permanent connection |
|
ParameterizingParameterizing the ipEther232.Modem can be performed either locally via serial interface using AT commands (Hayes command set) or via Ethernet network using the Windows graphical interface. Instead of using a phone number, the ipEther232.Modems are assigned a freely configurable IP address. |
