Escort LRP2000 manual Multi-tag Command Error Code, 131

6.7.5 Multi-tag Command Error Code

When the multi-tag commands encounter a fault condition, they indicate the error in a STATUS byte returned in the response. If any of the flag bits of the Status byte are set, then an error has occurred during command execution. In all other ways, the format of the response is the same as a successful response.

The STATUS byte is defined as follows:

7	Antenna Failure
6	R/W Error
5	Collisions
4	Internal Error
3	Timeout
2	Verify Error
1	Write Security Error
0	Reserved

Some of the error conditions are the same as those found in the single-tag commands, some are new and relate only to the anticollision. If any of the flag bits of the returned status are set, then that condition occurred during the command execution. Multiple conditions can occur in the same command.

Antenna Failure	There is an error at the antenna
R/W error	Error during the tag memory access
Internal Error	Internal error in low-level firmware (contact Escort Memory Systems technical assistance)
Timeout	Timeout expired
Verify Error	Set when re-read verification fails
Syntax Errors	Syntax errors (error code 21H) are returned in the same format as described for the single-tag commands.
