Protocol Faults

Here is a list of possible reasons that could be causing this error:

 No tag in the RF field

 Read/write power too low

 Antenna not connected

 Tag is we a k or dead

Solution

Make sure there is a good tag in the field and all parameters are set up correctly. The best way

to check this is to try few tags of the same type to rule out a weak tag. If none passed, then it

could be SW configuration such as protocol value, antenna, and so forth, or a placement

configuration like a tag location.

FAULT_NO_PROTOCOL_DEFINED – 401h

Cause

A command was received to perform a protocol command but no protocol was initially set. The

reader powers up with no protocols set.

Solution

A Set Current Tag Protocol (63h) command must be sent followed by resending the desired

command.

FAULT_INVALID_PROTOCOL_SPECIFIED – 402h

Cause

A Set Current Tag Protocol (63h) command was received for a protocol value that is not

supported with the current version of SW.

Solution

This value is invalid or this version of SW does not support the protocol value. Check the

documentation for the correct values for the protocols in use.
