AXLink Channels
Whenever communications with a Master is established, the Master assumes the ANT-RDR is at the default
channel status. Default channel status assumed by the Master is all Channels are OFF. However, the ANT-RDR
may not be in this default state and needs to inform the Master by sending an update for each channel that is
ON. After the ANT-RDR reports its Device ID to tell the Master it is online, the ANT-RDR should begin to
update the Master with any channels that are currently on.
The Guardian Channels are defined below:
Send Commands (Cont.)
?ER
Error Command
The Error Command (ER), command is sent by the Master to request the num-
ber of invalid tags reads encountered by the ANT-RDR.
The ANT-RDR will respond with the number of invalid tags reads, then it will
clear the invalid read count.
Note: The ?ER command does not care why there are invalid tag reads; it just
keeps count until it gets to a certain number and then it is cleared.
• Response: ER <NUMERR>
Where:
• NUMERR: the number of invalid tags reads encountered by the ANT-RDR
since the last ?ER request.
Examples:
SEND_COMMAND '?ER
Request number of invalid tags reads
SEND_ COMMAND 'ER 5
Report 5 invalid tags reads since last ?ER request.
VER
Request firmware version
This command is a request for the firmware version.
In response, the device sends a command in the form of 'vX.XX' (e.g. v1.02) to
the Master.

The Type column denotes who initiates the channel change. The Master directs the
ANT-RDR to change its state through channels with type CMD. The ANT-RDR

channels can be used for both CMD and FDBK.
