READREG
To read a register from the Bloodhound, enter the command READREG followed by the register number to
read. Register numbers are from 0 to 32767 and the register values range from 0 to 255.
To read a register enter the following command:
readreg 5
Register 5 is 1
VER
This command returns the version of the software load.
To check the software version load enter the following command:
ver [ENTER]
iBall Firmware V61
Boot Loader V17
REBOOT
This command performs a hardware reboot on the Bloodhound. This has the same effect as powering off the
unit and then powering back up.
STATUS
This starts the packet transmissions in the Bloodhound. If the registers are set up to do so, then the data
packets begin to be sent out the various communications port. The data packets are described elsewhere in
this document.
CALIBRATE
The calibrate command allows the user to set a calibration point for the vacuum, flow, and amperage settings.
The valid calibration modes are:
CALIBRATE AMPS[ENTER]
CALIBRATE VAC[ENTER]
CALIBRATE FLOW[ENTER]
To calibrate the amperage settings, disconnect any devices that are currently connected to the DC power port
on the side of the Bloodhound. After that enter CALIBRATE AMPS command. After a couple of seconds hit
the [ENTER] key and the new zero amps will be stored.
To calibrate both the sensors for the sample vacuum and the chromatograph pressure, first disconnect the
chromatograph pressure and sample vacuum lines from the sensors on the Brain Board. Then enter the
CALIBRATE VAC command. After a few seconds, hit the [ENTER] key to return to normal operations. After
calibration, the vacuum level will be set between -6 and -8 mmHg before connecting the lines. It will not show
zero. This is to compensate for tubing length. Reconnect the chromatograph pressure and sample vacuum
lines to the correct sensors on the Brain Board.
To calibrate the flow, connect a clear plastic flow meter to the sample port. The flow meter should be able to
read between 0 and 5 liters per minute (LPM). Since the Bloodhound is drawing a vacuum, connect the tubing
to the top of the flow meter. Then enter the CALIBRATE FLOW[ENTER]. The flow meter should drop to zero.
Turn the knob on the face of the Bloodhound clockwise until 1LPH is shown on the plastic flow meter. Wait for
the function to time out and the calibration will be set.
SETTIME
To remotely set the time or set the time through the serial port, enter the command
Settime [ENTER]
The Bloodhound will respond with the following string;
To set the time, use command SETTIME ???? VALUE
Use HOURS, MINUTES, SECONDS, DAY, DATE, MONTH, YEAR
Use only up to 2 digits in all fields
