displays “Ping Failed”.
4.4.4.5 Ping
addresses
Addresses may be entered by typing directly in
the “Ping Address” field in two ways:
1.
Numerically, the valid address range is
1-126.
2.
As an “Alpha-Mapped-Nibble” (AMN) ad-
dress, consisting of upper case letters in the
range A-P. The valid address range is A to
GN.
The base address is usually: 1.
The program may display one of the following
messages on the status bar:
“Ping address is not in AMN or number format”
or
“Ping address is not in the range A – GN”
In either case, check that the address entered is
within the acceptable range, is of a valid format
and correctly typed.
