PINGing Your IP Address By sending a packet to the specified address and waiting for a reply, the PING utility can determine whether a specific IP address is accessible. It also provides a particularly useful method for confirming addressing conflicts with your AXIS 2490 on the network.

The subsequent replies will provide an explanation as to the cause of the problem. Replies can be interpreted as defined in the table below: PING Reply bytes = 32 time = 2 ms. . . . . . destination host unreachable request timed out Interpretation and recommendation The IP address is already in use. This IP address is not used by anyone and is available for use with your AXIS 2490. How to test your setup Connect a serial port on the 2490 to a serial port on the PC using a null modem cable. Start a terminal program on the PC that accesses the serial port, e. g. Start a telnet session to the Serial Server IP address and the corresponding TCP port for the chosen serial port (default 4000, 4001, 4002). from the Start Menu and type: telnet ipaddress portnr, for example: telnet 10. 13. 7. 12 4000. Everything you type should appear in the terminal program when you press Enter, and everything you type in the terminal program should appear in the telnet window.
