Random Encrption mode 1
Communication can be made with the station that has Flag
40 or Flag 50. (The Master key and algorithm must be set
to the same value.)
40
00-79
Yes
Yes
Use the Air Key in the transmit data
Send the preset code from the transmit end
Fixed
3
Once algorithm is set to the same, communication can be
made with the statation that has Flag 40 or Flag 50. Since
the Air Key is sent from the transmit end, it is not necessary
to have the same Air Key at the receive end.
Random Encrption mode 2
Communication can be made with the station that has Flag
40 or Flag 50. (The Master key and algorithm must be set
to the same value.)
40
80-99
Yes
No
Use the Air Key in the transmit data
Send the preset code from the transmit end
Will change in every 20 mSec according to the algorithm
3
Once algorithm is set to the same, communication can be
made with the statation that has Flag 40 or Flag 50. Since
the Air Key is sent from the transmit end, it is not necessary
to have the same Air Key at the receive end. The code will
be scramblked and will change every 20 mSec.
Random Encrption mode 3
Communication can be made with the station that has Flag
40 or Flag 50. (The Master key and algorithm must be set
to the same value.)
50

Yes
Yes
Use the Air Key in the transmit data
Send the random coded Air Key from the transmit end
Fixed
3
Once algorithm is set to the same, communication can be
made with the statation that has Flag 40 or Flag 50. Since
the Air Key is sent from the transmit end, it is not necessary
to have the same Air Key at the receive end. The code will
be scramblked and will change every 20 mSec.
