AC4486 Specifications
Frequency Offset – Frequency Offset is an AC4486 protocol parameter used in conjunction with RF
Channel Number.
System ID – System ID is similar to a password character or network number and makes network
eavesdropping more difficult. A receiving transceiver will not go in range of or communicate with
another transceiver on a different System ID.
DES (Data Encryption Standard) – Encryption is the process of encoding an information bit stream to
secure the data content. The DES algorithm is a common, simple and well-established encryption
routine. An encryption key of 56 bits is used to encrypt the packet. The receiver must use the exact
same key to decrypt the packet; otherwise garbled data will be produced.
The 7 byte (56 bits) Encryption/Decryption Key is located in EEPROM Bytes D0 – D6. It is highly
recommended that this Key be changed from the default. In addition to setting the value of the
Encryption/Decryption Key in the EEPROM, the OEM can change this key in the transceiver static
memory during system operation by using the Write Static Bank #2 Byte command to modify
addresses D0 – D6h.
5.2.8 Auto Config
The AC4486 has several variables that control its RF performance and vary by RF Mode and RF
Architecture. Enabling Auto Config will bypass the value for these variables stored in EEPROM and use
predetermined values for the given mode. Below is a list containing all of the variables affected by
Auto Config and their respective predetermined values (values are all in hexadecimal format). When
Auto Config is disabled, these values must be programmed in the transceiver EEPROM for the
corresponding mode of operation.
