12. Data Integrity Flags
12.1. Bit Definitions
Bytes within the command string at offset location 12 and 13 make up
a 16 bit status flag. This 16 bit word can be monitored to determine if
there are any failures or data integrity problems within the RLB-35MC
capsule. If the flag word is at 0x0000, no fail reports have been
detected. A non-zero flag word would mean a failure has been
detected.

During normal operation port 7200 can be opened to request the
beacon’s error status at any time. When the command word is echoed
back, check for a non-zero flag word to detect any errors.
The error flags are returned in response to both the ‘S’ command and
the ‘E’ command with a ‘0’ subcommand. The CFC size and software
version are also returned for the ‘E’ command with a ‘0’ subcommand.
