4.1.4 Access Options

The AI-SRVR can be accessed through its Ethernet port or its console (serial) port.
Initially, the unit must be configured so that its IP address is set to a value placing it on
the same subnet as that in which it is being installed. The simplest way to do this is via
the console port. If a null-modem cable is not available, the unit can also be configured
via its Ethernet port and a Telnet session as described in Section 4.1.4.4.

4.1.4.1 Terminal Emulators

and PuTTY

These terminal emulators can connect to the AI-SRVR in either of two
ways:

by Telnet or the unit’s console port using a null-modem cable

(not provided). Earlier versions of HyperTerminal lacked Telnet
capability. Once a connection is made, either method of access
involves the same procedure and displays the same screens.

4.1.4.2 Console Port Access

With a serial null-

modem cable connected between the unit’s COM2 (DE-9) port and a

computer terminal (or a computer performing terminal emulation), the unit can be
monitored and configured. For proper EIA-232 communication:

Set the Baud rate to 57600.

Set the Data bits to 8.

Set the Parity to None.

Set the Stop bits to 1.

Set the Flow control (handshaking) to None.

Set Emulation to ANSI.

With console port access, no login is required. As soon as the unit boot-up process is
completed and the serial cable is connected, the screen will display the statistics screen
for the most recently used function

— AI-SRVR or AI-PROXY.

4.1.4.3 Telnet Access

The AI-SRVR includes a Telnet server. It is factory-programmed with a default IP
address of 192.168.92.68 and a Class C subnet mask of 255.255.255.0. Changing the
IP address is strongly encouraged. Once the AI-SRVR has finished booting and its
Ethernet port has been connected to the Ethernet network, Telnet communications are
possible. However, the AI-SRVR and any computer communicating with it must share
the same subnet. If they are not on the same subnet, they cannot communicate.
