Important!: When AES is enabled, every radio in the network must have matching encryption
strengths, encryption keys, and encryption channel keys, and the MCU Speed parameter set to 3 for
successful communication and data transmission.
5.3.1. Encryption Channel Key
Note: AES encryption settings are available only through the Setup menu in the terminal interface. If
the radio does not have Encryption enabled, menu option E in the (3) Edit Radio Transmission
Characteristics menu is blank and has no function.
Important!: This setting MUST match across all radios in the network.
Encryption Channel Key
Setting Description
Default Setting Blank
Options Any set of hexadecimal pairs identified in Description.
Terminal Menu (3) Edit Radio Transmission Characteristics > (E) Encryption >
(6) Channel Key
Description: The channel key is required when AES encryption is enabled for radios in the
network to link when AES encryption is enabled.
This setting is different from the Encryption Key parameter because it does not
encrypt the actual data but is required with the other Golden Settings, described in
a network, for the communication to take place.
Channel keys should be random and entered as hexadecimal values (e.g.,0 to F in
two-character pairs). Any combination of characters can be used for the key.
Example: A combination of numbers, or a sentence or phrase converted
into hexadecimal format.
Various string-to-hexadecimal converters are available on the Internet.
Enter the encryption key in 2-character hexadecimal combinations in lines 00 to
07 in the lines provided.
