Bloodhound ERROR Number Codes In the Error Field
In the Bloodhound packet, one of the fields is for error (condition) number codes. This number(s) represents
the current condition or conditions and notification of instance that needs to take place such as a blocked
sample line. Below is a table that shows the currently transmitted conditions and the corresponding error
(condition) code number. More than one condition can be present, and if so, are separated by a space.
Condition Code Associated Bloodhound Register Setting

B. WITS Data Fields Packet
The Bloodhound collects and monitors the WITS data that is available while during the drilling process.
The Bloodhound then collects all WITS data and builds a packet. It then sends the formed packet to the host
server. All packets start with common fields and the collected WITS packets are appended to it. The end of
the packet is terminated with a carriage return and line feed.
WITS Packet Example:
