CHECK TOWER LIGHT CONNECTION
Enter “ping command” on the Windows MS-DOS as follows:
C:¥WINDOWS>ping ***.***.***.***
(***.***.***.***: Enter IP address in decimal.)
ping ***.***.***.*** with 32 bytes of data:
Reply from ***.***.***.*** : bytes = 32 time < 10ms TTL = 64
Reply from ***.***.***.*** : bytes = 32 time < 10ms TTL = 64
Reply from ***.***.***.*** : bytes = 32 time < 10ms TTL = 64
Reply from ***.***.***.*** : bytes = 32 time < 10ms TTL = 64
Ping statistics for ***.***.***.***
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss)
Replies in case of normal connection are as shown above. If the connection cannot be established normally due to e.g. wrong
IP address, other replies such as ‘timeout’ will be received.
