+COMMAND BEHAVIOR SUMMARY
+========================
+
+PING
+----
+Format:
+    PING
+
+Response:
+    Analog_System_Monitor_<version>
+
+Purpose:
+    - Confirms the device is alive
+    - Allows PC-side auto-discovery
+    - Returns firmware version
+
+
+SETALL
+------
+Format:
+    SETALL: v0,v1,v2,v3,v4,v5,v6,v7
+
+Rules:
+    - Exactly 8 comma-separated values
+    - Each value must be numeric
+    - Each value must be between 0 and 100
+    - No extra values allowed
+    - No missing values allowed
+    - No trailing commas or extra characters
+
+Success Response:
+    OK
+
+Error Response:
+    ERROR
+
+Purpose:
+    - Updates all 8 channels in one atomic operation
+    - Applies calibration to each channel
+    - Resets watchdog timer
+
+
+UNKNOWN / MALFORMED COMMANDS
+----------------------------
+Format:
+    Anything not matching PING or a valid SETALL command
+
+Response:
+    ERROR
+
+Purpose:
+    - Keeps protocol strict and predictable
+    - Prevents accidental meter movement
+    - Simplifies debugging
