Description:
Description:
Thus, if the a segment is located on segment 1, the bits b3-b0 are “0000”. If b segment is
located on segment 2, the bits b3-b0 are “0001” and so on.

Byte2 and Byte3 follow the same pattern as above for the hotkey configuration. To
select any one of the key as hotkey, the bit value is set to ‘1’.
To Configure an RC hotkey two bytes are required. The first byte is used to specify
the RC address and the second byte is used to specify the hotkey command. Hence
there is the option of having 8 hotkeys from the same RC address or one hotkey each
for 8 different RC address.
