AMX Anterus manual AXLink Levels, Type Function Description

Programming

AXLink Levels

Levels are a means of applying a value to a physical element on the device. The ANT-RDR supports 8-bit levels only with values from 0-255 to represent RSSI values.

When a device comes ONLINE, the Master assumes the device is at the default level status with all levels set to 0. However, the ANT-RDR may not be in this default state and needs to inform the Master the value of any non-zero level.

After a 'LEVON' command is received from the Master the ANT-RDR sends a level update for any levels that are non-zero.

Level	Type	Function	Description
1	CMD/FDBK	RSSI Upper	The ANT-RDR will notify the Master that a tag's signal has been

			be acquired.
2	CMD/FDBK	RSSI Lower	The ANT-RDR will notify the Master that a tag's signal has been lost
		Threshold	when its RSSI signal is below the Lower Thresholds.
			• Range = 0-255, with 0 denoting the maximum range where a tag can
			be active before its signal is lost.
3	CMD/FDBK	RSSI Sensitivity	The ANT-RDR will notify the Master that a tag's signal has changed
		Range	when the current RSSI value is outside the range of the last sent RSSI
			value +/- the Sensitive Range.
			• Range = 0-255, with 0 being maximum sensitivity.
