from the “Bits per Second” pull-down. Click OK to close.
Finally click OK to close the Properties Dialog.
11. To read the revised baud rate, type the following com-
mand: #01BR[CR]
12. The DXD will respond with the following message:
BR=19200
1. The value retrieved with the PT (Pressure Type) com-
mand is the pressure type of the unit. It is comprised of 6
alphanumeric characters (including CR/LF) and specifies
the pressure type of the transducer. It is assigned during
manufacturing and cannot be changed. To read the pres-
sure type (gauge, absolute, vacuum, compound) type the
following command: #01PT[CR]
2. The DXD will respond by transmitting the following mes-
sage to the HyperTerminal window: PT=G (G for Gauge, A
for Absolute, V for Vacuum, C for Compound).
1. The value retrieved with the FS (Full Scale) command is
the full scale pressure range of the unit. It is comprised of
13 alphanumeric characters (including CR/LF) and spec-
ifies the pressure range of the transducer. It is assigned
during manufacture and cannot be changed. To read
the current FS value, type the following command in the
HyperTerminal window. #01FS[CR]
2. The DXD will respond by transmitting the following
message to the HyperTerminal window: FS=+30.000
(Note that the decimal position is range dependent. See
Appendix A for details.)
1. To read the current pressure in PSI, type the following
command in the HyperTerminal window: #01PS[CR]
2. The DXD will respond by transmitting the following mes-
sage to the HyperTerminal window: PS=+000.000 (or the
value of the current pressure)
1. The value retrieved with the HL (Heise Label) command is
the serial number assigned to the unit during manufacture
and cannot be changed. To read the value stored in the
HL location, type the following command: #01HL[CR]
2. The DXD will respond by transmitting the following mes-
sage: HL=000XXX (where X represents your DXD actual
serial number)
1. The value retrieved with the UL (User Label) command
is comprised of up to 16 alphanumeric characters which
can be modified by the user to form a descriptive tag or
identification name. To read the current User Name, type
the following command: #01UL[CR]
2. The DXD will respond by transmitting the following mes-
sage: UL=User Label Here (this is factory default value).
3. To change the current user label to “Test Point 01”, type
the following command: #01ulTest Point 01[CR]
1. The value retrieved with the UT (User Tare) command is
comprised of 11 alphanumeric characters which can be
modified by the user to remove, or “tare out” a pressure
preload from the displayed pressure value. To read the
current user tare value, type the following command:
#01UT[CR].
2. The DXD will respond by transmitting the following mes-
sage: UT=+000.000 (Note: This is the factory default
value and the decimal position will depend on the full
scale range of the unit)
3. To change the current user tare to 1 PSI, type the follow-
ing command: #01ut+001.000[CR]
