5.4.3.3 @RA RSSI absolute value measurement
Measures the absolute value for Received Signal Strength Intensity (RSSI) of the channel set. The measured value
is a hexadecimal value that indicates the RSSI absolute value.
The code of the RSSI value acquired is minus.
Format 1: ‘@’ + ‘RA’ + ‘CRLF’

5.4.3.4 @RC All channel RSSI absolute level measurement
Measures the RSSI (Received Signal Strength Intensity) over all channels. It is possible to check the floor noise
level of the field, third party field level, and field level of the system itself. The measured value is output as a 2-digit
hexadecimal number in ASCII characters that expresses the absolute value for RSSI. The code of the RSSI value
acquired is minus.
Format 1: ‘@’ + ‘RC’ + ‘CRLF’
Example: Measure the RSSI absolute value over all channels.
Monitor command: @RC

A response is returned for 64 channels of RSSI data (128-byte ASCII characters)
The code is minus. 7A = -122dBm
