Computer Requirements: Any PC capable of running Win-
dows XP, or Win7 or Win10™ can be used.
Software: A data stick (flash drive) is available for the DXD
transducer that provides an easy means of setting up the user
configurable features of the DXD along with data logging and
display capabilities, also avilable for download on our web site.
DXD w/ USB Users: After connecting the DXD into the USB
connector of your PC it will be necessary to determine which
communications port Windows has assigned to the DXD.
This communications port assignment must be matched to
the communications port used within the DXD utility.
To find the assigned port: Go to your PC’s “Control Panel”
through the “Start” menu of your PC. Select “Device Man-
ager” (it may be under “System” / “Hardware” on some oper-
ating systems). Pull down the “Comm Port” headings and
look for the communications port assignment for the DXD.
To verify which comm port was assigned, if not evident, you
can remove the DXD from the system and see which port
disappears after the device manager automatically updates.
Re-connect the DXD and see which port is re-established.
Match that port to the comm port in the DXD utility.
For use with Windows 7, 10 a 3rd party terminal emulation
program can be used (HyperTerminal™, Tera Term, PuTTY
etc.). Windows XP includes a utility terminal emulation pro-
gram called HyperTerminal™. A terminal emulator can be
used to set up user preferences such as (DXD) address, label
etc. and also to read pressure. The following section will
guide you through the steps required to accomplish this. This
tutorial in DXD command structure utilizes HyperTerminal™
as the reference, but should be adaptable to any other termi-
nal emulator, provided you are familiar with the setup charac-
teristics of those programs. The command syntax illustrated
in the following section will familiarize you with how they are
implemented if you wish to write your own program.
Basic Setup Information
Each DXD transducer is configured for address value = 01
and bit rate = 19,200 bits per second as shipped from the
factory. These values can be changed, however, the following
instructions assume that you are using the DXD in the factory
configuration.
Signal and Power Connections
Make all electrical and power connections as described in
Section 5.0. IMPORTANT: Be sure to connect only one DXD
until you are familiar with addressing conventions.
The HyperTerminal™ application prompts you through the
process of setting up communication parameters that include
assigning a file name and icon and also setting the com port,
data format, bps (bit per second). After this is done, you can
save the configuration using a name like “DXD” and simply
open it by name without the need to re-configure it each
time it is used. This application will work with RS-232 ports,
RS-485 ports or USB to RS-232 (RS-485) adapters.
1. Click the Start Button on the task bar and drag up to Run…
2. Type “hypertrm” in the text box and click OK.
3. You will be prompted for a name, so use something easy
to remember, like DXD. Type the name and select an icon.
Click the OK Button.
4. In the next box you may be prompted for a phone number.
Pull down the Connect Using box and choose the appro-
priate Com Port and click OK. (note – a phone number
isn’t used in this type of setup).
