REG. FUNCTION Units Range Factory
Setting
COMMENT
4 External code version. This register holds the external firmware code
version.
5 Absolute number of
resets high byte
Register 5 and 6 work together to make an
unsigned integer which is the absolute number
of resets from the very first power up.
6 Absolute number of
resets low byte
Register 5 and 6 work together to make an
unsigned integer which is the absolute number
of resets from the very first power up.
9 Enhanced Gas unit
feature set - multi
sensor set
This turns on and off the patent pending
software feature set that allows the Bloodhound
to utilize the full range set of the sensors and
automatically calibrate and maintain itself
Normally set to 1 or on. Set to 0 for off.
8 First time power up
register setup
85 If this register is not 85 then a routine is called
that will set the registers to factory levels. This
register tells the BH if it has ever been booted
before. On a first time startup, the BH sets all
255 registers to a factory default and then sets
Register 8 to 85.
10 SUCTION PUMP
MANUAL SETTING
(Flow meter override)
0-199 0 This register is used to set the pump to a static
level in case the electronic flow meter fails. If
this is register is not zero then the BH takes this
number and forces the sample gas pump to stay
at this power level, typically 170 is a good
number to start with. If this register is set to 0
then the BH uses feedback from the electronic
flow meter to regulate the speed of the suction
pump.
11 Flow meter regulated
flow rate
Liters
per
Hour
(LPH)
60 Sets the flow in LPH, that the BH will regulate
to. The BH takes readings from the electronic
flow meter and regulates its sample gas pump
and flow rate. If this register is set to 255, the
sample gas motor is turned all the way on.
12 Gas readings out to
WITS
1 If this register is not 0 then the BH will send gas
readings to the WITS interface after a good
connection is made to the WITS interface using
the null packet. If this register is 0 the BH will not
send any gas readings out the WITS interface,
but will continue sending the null packet to keep
the connection going.
15 GC INJECT TIMING MIN 5-12 8 When this time expires, the BH will start another
chromatograph injection and cycle. Setting the
column temperature to a higher level will allow
for the separations to transfer through the
column at a faster pace which will allow the user
to reduce this injection timing but may lose the
C1 C2 separation.
