required. If continuous read is not requested, executing
this command will invoke a single read of the Negative

requested, the read executions will continue until any
key is touched to abort reads. It is generally not expected
that this register will be read in continuous mode.
Examples:
1. Write 8 (hex) to the Offset Calibration Register and
then read it back. To accomplish this task, choose the
m Main Menu
w Write Menu
Write Menu option from the Main Menu, choose the Off-
set Register option from the Write Menu. Enter 000008

Exit Program
Entering 1 from the Read Menu invokes a read commu-
nication cycle with the Data Output Register. The Data
Output Register will be read one time, the data will be
displayed, and the program will return to the Main Menu.
Entering 2 from the Read Menu invokes continuous read
communication cycles with the Data Output Register.
Refer to the Software Clari?cations section of this docu-
ment for details on the displayed data. Continuous data
reads will be displayed until any key is pressed. When a
key is pressed, the program returns to the Main Menu.
Entering 3 from the Read Menu invokes a read commu-
nication cycle with the Control Register. The user will be
asked if a continuous read is required. If continuous read
is not requested, executing this command will invoke a
single read of the Control Register, display the data and
return execution to the Main Menu. If continuous read is
requested, the read executions will continue until any
key is touched to abort reads. It is generally not expected
that this register will be read in continuous mode.
Entering 4 from the Read Menu invokes a read commu-
nication cycle with the Offset Calibration Register. The
user will be asked if a continuous read is required. If con-
tinuous read is not requested, executing this command
will invoke a single read of the Offset Calibration Regis-
ter, display the data and return execution to the Main
Menu. If continuous read is requested, the read execu-
tions will continue until any key is touched to abort reads.
It is generally not expected that this register will be read
in continuous mode.
Entering 5 from the Read Menu invokes a read commu-
nication cycle with the Positive Full Scale Calibration
Register. The user will be asked if a continuous read is
required. If continuous read is not requested, executing
this command will invoke a single read of the Positive
Full Scale Calibration Register, display the data and
return execution to the Main Menu. If continuous read is
requested, the read executions will continue until any

Now select the Read Menu option from the Main Menu,
choose the Offset Register option from the Read Menu.
The user will be prompted to decide upon a single read
or continuous read. Enter n for a single read. The data
read will be displayed on the screen and the program will
return to the Main Menu.
2. Con?gure the device for bipolar mode, offset binary
coding, 10Hz ?lter notch frequency, gain of 1, and
conversion mode operation. Select the Change Mode
Menu option from the Main Menu and then the Custom
Menu option from the Change Mode Menu. When
prompted for data coding enter 0 for offset binary. The
next prompt is to enter the notch frequency, enter 10 for
10Hz. Next, the operational mode table is displayed,
choose 0 for conversion mode. The next prompt is for
bipolar/unipolar operation, enter 1 for bipolar mode. The
next screen displays the gain selection table, enter 1 for
gain equal 1. The program determines the data required
to con?gure the HI7190 as the user speci?ed and
invokes the proper communication cycle. Execution
returns to the Main Menu.
Software Execution
The PORT_ID.DAT ?le contains the port identi?cation for the
parallel printer port interfacing the HI7190 Evaluation board
to the PC. This ?le needs to be edited (as discussed in the
HI7190RDME.TXT ?le) before running the software. The
DOS MSD command can be used to ?nd the printer port
identi?cation.
Loading Software: Copy the four ?les (7190BTA5.CPP,
7190BTA5.EXE, PORT_ID.DAT, and 7190RDME.TXT) from
the diskette onto your PC hard drive into the directory of your
choice. The ?le 7190BTA5.CPP is the evaluation software
source code. The ?le 7190BTA5.EXE is the executable pro-
gram and 7190RDME.TXT is a README ?le containing
valuable information. Please read the 7190RDME.TXT ?le
before continuing.
