Anterus RFID Solution

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.

Function

Description

1

CMD/FDBK RSSI Upper 

Threshold

The ANT-RDR will notify the Master that a tag's signal has been 
acquired when its RSSI signal is above the Upper Thresholds.
• Range = 0-255, with 0 denoting the maximum range where a tag can 

be acquired.

2

CMD/FDBK RSSI Lower 

Threshold

The ANT-RDR will notify the Master that a tag's signal has been lost 
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

Range

The ANT-RDR will notify the Master that a tag's signal has changed 
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.

The 

Type

 column denotes who initiates the level change. The Master directs the 

ANT-RDR to change its state through Level of type CMD. The ANT-RDR informs the 
Master of state changes through Levels of type FDBK
