Channel Switch Setting - AOR ARD9900 Instruction Manual

Channel Switch Setting

There are 16 different channel settings for the ARD9900. By simply rotating the channel
switch on the front panel of the ARD9900 to the desired setting, a pre-programmed
encryption mode can be easily recalled from the memory.
To set the Channel Switch setting, first type the [AMA] command to gain entry into the
data management menu.
Rotate and select the desired channel switch position (0 ~ F).

@@@@@ Netmask
F (1): Netmask valid
& Communication mode (Displays the communication mode on the channel)
0 : Non encryption mode
1 : Digital squelch mode
2 : Fixed encryption mode
3 : Random encryption mode
! ! ! ! ! Other party's ID (Set other party's unique ID i.e. their AUI code)
I D : 00000 ~ 99999
@@@@@ Netmask
(Set Netmask
invalid)
Enter "1" or "0" to each digit.
1 : ID digit valid
0 : ID digit invalid
Note : On the PC screen, "1" will be displayed as "F."
X X Setting mode 80 : Non encryption mode
00 : Fixed encryption mode
40 : Fixed airkey random encryption mode
50 : Random encryption mode
Z Z Algorithm
Note : When the communication mode is set to Non Encryption mode (80), then the algorithm must be set to
either[ 0 0 ] or [ 01] .
00 : Non encryption mode (default)
01 : Digital squelch mode
Note : When the communication mode is set to Fixed Encryption
mode (00) or Random Encryption mode (40, 50), then the
algorithm must be set as follows:
00 ~ 79 : Fixed Scramble Code
80 ~ 99 : Variable Scramble Code
(every 20 mS)
Note : When you execute the ACP command, it will not display detailed communications settings or algorithm

(Standby for command)
(Press the space key of the PC keyboard)
(Other party's unique ID i.e. their AUI code)
(Current Netmask)
0: Netmask invalid
The net mask serves to identify how much of the other party's unique
valid/ ID i.e. AUI code is necessary for communication to be achieved. If you
enter an ID of 12345 and a net mask of 11100 only the first three digits
will be required to match for communication to take place. This means
you can arrange a net communication if all members AUI identifier
begins with the numbers 123.
Set communication algorithm
(Response)
This is how the modes are displayed under the
ACP command, they cannot be entered as 1 digit
codes like this, they are entered as part of the
setting mode and algorithm setting parameters
