(opt. value
is 5)
This is the size, in hundreds of microvolts, of the
noise window for the chromatograph. Typically
20 (= 2000 microvolts = 2 millivolts) on the
HRM03
67 WITS data sending
mode
0 0 = Send with Pason WITS handshake (note:
zero DOES work with Rigwatch & TOTCO)
1 = Send with no handshake (only for special
clients who want no handshake)
68 WITS C values sending
format
0 0 = Send as Gas Units
1 = Send as PPM
10. DATA INFORMATION, STORAGE AND TRANSMISSION
All information within the
Bloodhound is stored or transmitted as a common text-based string or file. If a new
job number is entered through the computer panel or set remotely, the
Bloodhound will rename the old file and
start a new file for the data to be stored under.
The data that is transmitted to the Internet or via the serial port by the Bloodhound is in simple ASCII human
readable packet form. The packet is broken into fields that are separated by commas. An example of the
main data packet that is transmitted is as follows:
*5727_0011,2013/12/15,10:14:44,12404.6,3703.08,13.52,0.00,100,93.7,0.746,80.393,6
0,-18,13.2,4.095,1.725,711,0.7114322,0.382,0.00,12
,21,100,121.5,60,0.0,97.4,1124,2688658,409.47,515.28,531.41,589.42,517.47,-

A Bloodhound Minimum Data Packet is always sent internally to the SD card and the USB memory stick, if
installed, for storage.
The Bloodhound will send other packets of information based on internal activity. If the user has other
equipment connected to the Bloodhound and is only interested in gas detection information then it should be
configured to ignore all other packets.
The simple checksum is the 8 bit rollover sum of all the ASCII characters starting with and including the ‘*’ and
ending with and including the ‘,’ preceding the checksum delineated item. The checksum delineated item will
always have a preceding capitol C before the ASCII number such as “C91”. The checksum will always be the
last item on the list.
All other packets that are generated from the Bloodhound start with other symbols and also end with a carriage
return and line feed.
If the packet starts with a “*” then it is the main Bloodhound data packet.
If the packet starts with a “^” then it is a WITS data packet information.
If the packet starts with a “@” then it is a Bloodhound minimum data only packet.
