Command Format

Run a terminal software program such as Windows HyperTerminal, and then turn the power of
the ARD9900 on.
The following message should appear on the PC screen:

This indicates the ARD9900 is ready to accept commands from the PC.
Each command consists of three (3) alphabetical characters:
Random Encryption Mode 4
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
80-99
Yes
Yes
Use the Air Key in the transmit data
Send the random coded Air Key from the transmit end
Will change in every 20 mSec according to the algorithm
3
Once the mode code and algorithm is set to the same at both ends,
communication can be made with the station 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
scrambled and will change every 20 mSec.
