HPB\HPA User Manual
• SET DEVICE ID
To give the HPB an assigned address of 01 up to 89, enter the following commands:
Type: *00WE
Type: *00ID=01
Type:
where:
•
READ PRODUCTION DATE
To read the production date, enter the following command:
Type:
(Actual responce depends on production date of device being used.)
•
READ CONTINUOUS PRESSURE
For continuous pressure readings at the factory set default rate of 5 per second, enter the following
command:
Type:
Type:
•
CHANGE TO A NEW SAMPLE RATE
Enter the following command:
Type:
Type:
The sample rate will change to one every 2 seconds. I= is an abbreviation for Integration time which
determines how long to accumulate pressure samples between readings. Each integration period
gathers the data for one pressure reading output (see Section 4.2 What is integration?). The range of
integration times can be set by specifying readings per second (I=R45 for 45 readings/sec) or time delay
in 100 millisecond intervals (I=M60 for 6 seconds). The factory set integration time is 5 samples per
second (I=M2).
The output data rate can also be altered by use of the idle count (IC) command or by using the reading
rate (RR) command in conjunction with the operating mode (OP) command. See Section 4 for
description of these commands.

<cr> This enables the HPB to change a parameter in RAM
<cr> This sets the null addressed HPB to device ID=01.
Note: The device ID is now used in the command input
*01S= <cr>
Response: #01S=00052036
The ―#‖ now replaces the ―?‖ in the header and indicates the HPB response
is from an address assigned unit.
* indicates the start of a command
00 is the null address of the HPB
WE is the command to enable a configuration parameter change
ID is the command to change the device address
01 is the assigned HPB address for this example
S= is the command to read the serial number
*01P= <cr> Response:
*01P2 <cr> This enables a continuous stream of compensated pressure readings to flow
into the terminal program.
$*99IN <cr> This is the best way to stop the continuous pressure reading commands.
The ‗$' character temporarily stops, or suspends, either the continuous
pressure or temperature readings. The *99IN command stops the
continuous pressure readings.
*01WE <cr> This enables the HPB RAM to accept a changed parameter.
*01I=M20<cr> This sets the integration time to value 20, which corresponds to an output
sample every 2 seconds.
