Connecting the Telnet Host
Before starting the management and configuration activities, it is necessary to
establish IP communication between your Telnet host and the IR-IP interface
module. For this purpose, it is necessary to provide a communication path.
Because of the method used to assign an IP address to IR-IP Ethernet port, it is
recommended to connect the Telnet host directly to the IP router 10BaseT
connector. This is made by connecting an Ethernet cross cable between the
Ethernet connector of the Telnet host and the IP router connector.
However, you may also connect through a common LAN: in this case, connect
your Telnet host and IR-IP to Ethernet hub ports using straight cables.
Preliminary Telnet Host Configuration
You can use the IP learning mechanism to configure the IP communication
parameters of the IR-IP LAN interface. In this case, skip to the
Assigning the Router
LAN Interface Address section below.
If you prefer to use the factory-default parameters to establish IP communication
between your Telnet host and IR-IP, configure the Telnet host as follows:
1. Temporarily configure the host IP address as 192.168.205.2.
2. The initial destination IP address to be used by the host is 192.168.205.1.
The first step in the preliminary configuration process is to assign the desired IP
address to the LAN interface of the IR-IP interface module.
After an IP address is assigned and saved, you must change the destination IP
address of the Telnet host to the new address, otherwise it is not possible to
continue the configuration process. At the same time, you can also change the
temporary IP address assigned to the host (192.168.205.2) back to its permanent
address.
Assigning the Router LAN Interface Address
The IP address of the IR-IP LAN interface must be configured as part of the
preliminary configuration process. To simplify this process, IR-IP includes a simple
and convenient IP address learning mechanism.
The IP address can be configured and changed at any time, even after the
complete IR-IP configuration process has been performed, because it does not
affect other configuration parameters. Moreover, the IP subnet mask is
automatically adapted to the new IP address.
IP Learning Mechanism
To simplify the configuration process, IR-IP has a special mechanism for
configuring the IP address of its LAN interface. Setting section 1, called IP address
learning, of the IR-IP DIP switch (see
Table B-2 ) to ON enables this mechanism.
The IP learning mechanism enables IR-IP to learn its LAN interface IP address by
receiving frames sent by a ping utility to the prescribed LAN IP address.
