ACCU-CAL PLATINUM RS-232 COMMUNICATION
Enclosed are instructions for establish-
ing communications between the Accu-
Cal Platinum Digital Test Gauge and a
personal computer (PC) utilizing the
Hyper Terminal communications soft-
ware included in the Windows xP
Operating System. A custom cable
assembly (3D Instruments Part Number:
2025-0004) is required to complete the
link-up.
To set up remote operation of the gauge via
the Windows Hyper Terminal program, first
connect the gauge, via the special cale, to
a COM serial communications port on the
PC. The following procedure details how to
set up the Hyper Terminal program to allow
bi-directional communication between the
Accu-Cal Platinum and the PC.
1. Start the Hyper Terminal program ...
click on: All Programs/Accessories/
Communications/Hyper Terminal.
2. In the "CONNECTION DESCRIPTION"
box, enter a name for your communi-
cation routine (i.e.: Accu-Cal Platinum)
and then click: OK
3. In the "CONNECT TO" box, under
"Connect Using", choose the appropri-
ate serial port on the PC to which the
gauge is connected (i.e.: com1) and
then click: OK
4. In the "XXX PROPERTIES" box (where
XXX = serial port selection in #3
above), under "port settings", enter the
following serial port settings:
A) Bits Per Second:
B) Data Bits:
C) Parity:
D) Stop Bits:
E) Flow Control
click: OK
5. At this point, the "HYPERTERMINAL"
box will appear. Click on: FILE and
then: PROPERTIES ... the "YYY
PROPERTIES" box (where YYY=name
assigned to the communications rou-
9600

Xon/Xoff
tine in #2 above) appears. Click on:
SETTINGS and then click on" ASCII
SETUP. A box titled "ASCII SETUP"
appears ... check the following items:
A) In the "ASCII Sending" section:
Send line ends with line feeds.
B) In the "ASCII Sending" section:
Echo typed characters locally.
C) In the "ASCII Receiving" section:
Append line feeds to incoming line
ends
Note: In the "ASCII Receiving" section,
the line "wrap lines that exceed termi-
nal width" should already be checked.
Click: OK
6. Click: OK to exit this box.
The gauge is sent from the factory in
the "query" mode ... meaning that the
information is supplied in response to a
given after a query. Refer to the List of
Query Commands in Table 1 on Page 10
for information on commands. These com-
mands can be used after you have estab-
lished communication with the gauge. The
Accu-Cal Platinum can also be configured
to transmit this information in a "streaming"
mode, whereby lines of data are sent auto-
matically to the PC. Once communication
with the gauge is established, type in the
command: stream_on and press the
ENTER key. The gauge is now in the
"streaming" mode.
Note: This setting will now be saved in
non-volatile memory as the default mode
of RS-232 communication.
The displayed information, when the gauge
is in the "streaming" mode, will appear in
the form:
A, B CC.C, D
Example: 0, PSI 24.4 Cel
where: A = pressure reading,
B = Engineering Unit selected for pressure
reading, CC.C = temperature reading and
D = unit of temperature measurement.
