4.3  Additional test details
4.3.1  RF Data Link Test
A link test between a mobile and a known base
station can be done using the WinRIS "Address"
and "Send" functions. The “Address” and “De-
vice” fields, the “Send” button and the “Chat”
message screen are used to send messages to
specific mobile or base or to carry out RF test.
Start by entering the address of the mobile (or
base station) you wish to send a test message to
or test:
1-  Specify the address:
Addresses may be entered by typing directly in
the “Address” field in two ways:
Numerically, the valid address range is
1-126.
As an “Alpha-Mapped-Nibble”  (AMN)
address, 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:
For Paragon
PD
 products:
“address is not in AMN or number for-
mat”
For mobile products:
“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.
2-  Enter the Device number for mobile (or base
station).
3-  Press the Send button.
The Chat window reports “Sent to xx mo-
bile” (where xx is mobile name).
If test is successful:
Status line reports “Delivery confirmed.
If test unsuccessful:
Chat window reports “Waiting”,
Then the Status line reports “Delivery
Failed”.
