Communication Mode Setting
The communication setting is set into discrete channels.
[Procedure]
Using the AMA command, enter the Master Key Code to gain access to the System
1.
Management Screen.
Select the desired channel on the front panel.
2.
Using the ACP command set the desired communication mode setting.
3.
To verify details of the setting, use the ACP command.
To verify details of the communication channel, use the ADS command.
[Example]
ACP [CR]
CH : 5
ID : 12345
NM : FFFFF
MD : 0
Checking with the ADS command would reveal the following:
Flag:80
Algorithm:00
AirKey:0000
UserID:77777
CH:8 ID:12345 NM:FFFFF MD:0
The ARD9900 provides 16 channels (A~F, 0~9) and has a digital squelch system that enables
you to avoid hearing any transmissions that are not specifically intended for you. This is
achieved by matching the remote stations AUI (or part of it) using the ID command and setting
the appropriate NETMASK. This is only applicable to those modes that have a squelch
function attributable to them; referring to the communication selection guidance table on page
19, you will see that this is applies to modes 1 and 3 only. You can assign each channel for the
remote ID of your chosen contacts, and use the NETMASK feature to set up group
communications. Depending on your desired communication scenario, you can then select the
channel number suitable. Take the following steps to perform the channel setting:
1.
Decide on your own individual identification number and program this using the AUI
command. Type AUI at the System Manager command prompt, press return and the
current 5 digit setting will be displayed. To change this to your chosen number type
AUI_xxxxx (where xxxxx is your chosen 5 digit code) and press return. The AUI number
is now saved in the memory of the ARD9900. Note that only numbers not letters or any
other characters are acceptable.
2.
Select the TX channel [CHAN] where you want to assign the ID, NETMASK and
SQUELCH parameters (and any encryption you wish) using the front panel switch and
program the information using the ACP command.
The system works by using the ID (AUI) of the station you are attempting to communicate with,
and the NETMASK to define how much of that ID is used. If you are contacting someone with
an ID of 12345 and you use a NETMASK of 11111 this means you are requiring all five of the
digits of the other user to match before their digital squelch will be broken and communication
can take place.
ACP [CR]
ADS [CR]
CH: 5 ID : 12345 NM : FFFFF MD : 0
Channel 5 is selected
Destination ID is set to 12345
Displays the nest mask setting. [ F] is indicating the digit is valid.
Communication mode is [ 0 ] (Non encryption mode entered as 8000).
This would have been entered as:
ACP_12345_11111_8000
None encryption mode
Digital squelch off
Air key (previously set with AAK command)
Your unique user ID set with the AUI command
