Versions 3.5 and higher of the AC5124 family firmware implement an AT Command set, which is used
for modifying settings during runtime without having to use any hardware control lines. AT Commands
are valid for modes 1, 2, and 4 of the AC5124. Whether in mode 1, 2, or 4, this command must be sent
to the radio as a complete packet. Any characters before or after this command that become
appended to this string to form a larger packet will cause the packet to be interpreted as a packet to
send over the RF and not an AT command. If the AT command set is used in mode 2, the end
character must be 0DH (13 decimal). If the AT command set is used in mode 4, the fixed length must
be set to 6. If power is lost while in AT command mode, the radio will power back up into normal
mode. All AT command characters should be capitalized. All AT commands end in a 0DH character
(13 decimal). The radio will not respond to an AT command unless the 0DH character is detected at
the end of the command.

IRAM is an acronym for Internal Random Access Memory. IRAM is a static memory that holds many of
the parameters that control the radio such as channel number. Using the Read/Write IRAM command
allows these parameters to be changed dynamically. Because IRAM is static, when the radio is reset,
these parameters will revert back to the settings stored in the E²PROM. Be careful not to change
undocumented IRAM addresses as undesired operation may occur. Below is a list of IRAM
parameters that can be changed in the radio:
