Installing the Configuration
Software
Refer to Table 1 for the equipment needed.
1. Insert the Moore Industries Interface Solution
PC Configuration Software CD into the CD
drive of the PC. Access the CD and open the
PSD SPD PC Configuration Software folder.
2. Double-click the installation program located
in the folder. Follow the prompts to correctly
install the program.
Once the Configuration Program is installed on the
PC, the PSD can be connected to the loop or to
equipment to simulate and calibrate input. You can
then view and/or change the instrument’s parameters.
No PSD Required
It is not necessary to connect the display to a PC while
creating configuration files using the Configuration
Software. The Configuration Program can be run
without connecting a PSD, and most operating
parameters can be set without benefit of an attached
unit.
This makes it easy to create a set of operating
parameters, save and download them to one or more
transmitters at a later time.
The PSD must be connected to the PC in order to:
capture input, assign a tag, receive (via download) a
configuration file and save the configuration file from
the instrument’s memory.
Configuring the PSD
One of the benefits of the PSD is that it has no internal
or external controls to adjust or settings to change. All
operating parameters are set using Moore
Industries’ Intelligent PC Configuration software.
Once these software settings are made, they are
downloaded to the instrument in the form of a
Configuration File and stored in the unit’s non-volatile
memory. You can choose to save a backup copy of
the file on your PC hard drive or other external media.
The transmitter communicates with the PC through
a cable connection to the PC’s serial (COM) port or
optional USB cable.
The serial cable is P/N 803-040-26 and the USB cable
is P/N 804-030-26.

Using the PC Program
The PSD PC Configuration Software is used to
program all of the PSD’s parameters. The PC
Software is made up of these sections:
1. Arrow Buttons–Three Arrows here are used for
Downloading to Unit (down Arrow), Uploading from
Unit (Up Arrow),or Get Set-up (Right Arrow).
Note:
After uploading file (by pressing the Up Arrow), you
must press the Right Arrow button to populate all
information into the configuration dialog area.
2. Status–This portion of the screen displays the
activity of the connected unit. It will show you if the
unit is Idle, Uploading, Downloading, or Monitoring.
3. Process Variables–This displays two variables: the
loop signal in mA and the loop signal after the PSD
has converted it to the designated EGU.
4. Input Settings, Output Setings, Tag, and Device–
These three sections display the configuration of the
connected PSD.
Figure 4. Most of the PSD Operating Parameters can be set from the Main Screen of the Configuration Program.
5. Connection–Check this section to track the status
of the PC’s connection with the PSD.
6. Input/Output & Custom Curve Tabs–Displays all
the information to program the PSD with either a
standard, linear curve (Input / Output), or with a
custom linearization curve (Custom Curve).
6. Input Configuration–Displays the input settings
proposed for the transmitter. The two different capture
buttons permit you to capture the input span.
7. Display Configuration–Shows the display settings
proposed for the PSD.
8. Engineering Units (EGU), Linearization Mode,
Filter, Display Resolution, and Damping Time–This
set of radio buttons and edit boxes allow you to input
different
values proposed for transmission to the PSD.

Figure 5. Connecting the PSD to a 4-20mA Loop
Connecting the PSD to PC
It is recommended that the PSD be installed in the
loop before it is configured so that you can use the
input capture feature to capture the exact full and
zero values of the loop. See Figure 5 for a hookup
diagram, and Table 1 for a list of necessary equipment.
If it is not possible to hookup the PSD to the loop,
you can also use a variable current source and an
ammeter or multimeter to setup your unit before
you install it on the loop. See Figure 6 for a hookup
diagram, and Table 1 for a list of necessary equipment.
The PC Configuration Software can program and
save the settings for the PSD without having a PSD
attached, but you do need to attach the PSD as shown
below in order to download information.
Caution: Unplugging the programming cable or
resetting power while downloading to the unit could
result in a default configuration / calibration and the
unit may have to be returned to the factory.

generate a custom table that can be easily saved
and imported into the Universal PC Configuration
Software.
To generate your own table, follow the instructions
below.
1. From the START Menu, click on PROGRAMS,
MOORE INDUSTRIES, then CURVE GENERATOR.
The program that is shown below will appear.
Figure B-1. The Square Root Curve Generator program will allow
you to easily create any custom square root curve that you need.
2. Enter the values for the input and display into the
appropriate boxes. Enter the number of linearization
points that you would like generated into the NUMBER
OF LIN. POINTS box.
3. Click on GENERATE to create the table, then enter
the name you would like the table saved as.
4. Close the Curve Generator and open the Universal
PC Configuration Software. Click on the FILE menu,
then on IMPORT CUSTOM CURVE. Select the
“view all files” on the OPEN dialog box, then find the
file name that you just saved.
5. Verify all settings.

Figure 6. Connecting the PSD to configuration equipment
Programming the PSD
There are two sections for programming the PSD –
“Input/Output,” and “Custom Curve”. The Input/
Output tab allows you to program the PSD with a
normal, linear curve; the “Custom Curve” allows you to
program the PSD with a custom linearization curve.
Programming the PSD with a Normal (linear) Curve
It is a simple process to program the PSD with a
normal curve. Using the “Input/Output” tab, you will
need to adjust the following settings.
1. In the “Input Settings” box, enter the Zero and Full
Input values, or click the “Capture” buttons (this is the
preferred method) and adjust the input.
2. Go to “Display Settings” and input the range you
would like displayed on the PSD’s screen.
3. Enter a name for the unit (to be read by the PC
Program) in the “Tag” box.
4. Enter into the “EGU” box the engineering unit you
would like displayed.
5. “Linearization Mode” should be left at “Normal”.
6. Set the “Filter” to match the frequency of the filter
for the AC power mains in your country.
7. Set the “Display Resolution” to the number of
decimal points you would like the PSD to display.
8. Smooth out input variations by increasing the
Damping Time.
9. Download the new settings to the instrument by
attaching the instrument to the PC and clicking on the
download button.
Programming the PSD with a Custom Curve
There are a variety of ways to program the PSD with
a custom curve. You can import a comma-delimited
table that you have written in another program (for
example, design the table in Microsoft®Excel and save
it as .csv type). You can import a ready-made file that
came with your configuration software (such as the
square root table). Or, you can set your own custom
curve by follwing the directions described below.
1. Set the “Linearization Mode” to “Custom”. In
the “Linearization Data” box, enter the number of
linearization points. Then, in the “X data” column
of the table, enter the value of the loop input in
mA. In the “Y data” column of the table, enter
the corresponding EGU value that you would like
displayed. Do this for each point of your custom curve.
It may be useful to use the buttons in the “Commands”
box to work with the custom curve table cells.
2. Set the “Input Settings” to the span of the loop you
will be reading.
3. Set the “Display Settings” to the span that you
would like to have displayed. This allows you to reset
the range of the display with one step instead of
needing to recalculate the entire custom curve table.
4. Click on the “Input/Output” tab so that you can set
the Filter, Display Resolution, and Damping Time to
the appropriate values.
5. Download the new settings to the instrument by
attaching the instrument to the PC and clicking on the
download button.

Site-Viewing the Configuration
Even after your PSD has been installed in the field,
it is easy to verify its configuration using the front-
mounted View button. Figure 7 describes the various
displays controlled by the View button.
Installation
Installing the PSD in your loop involves mounting and
making electrical connections.
Recommended Ground
Wiring Practices
Moore Industries recommends the following ground
wiring practices:
• Any Moore Industries product in a metal case or
housing should be grounded.
• The protective earth conductor must be connected
to a system safety earth ground before making any
other connections.
• All input signals to, and output signals from,
Moore Industries’ products should be wired using
a shielded, twisted pair wiring technique. Shields
should be connected to an earth or safety ground.
• For the best shielding, the shield should be run
all the way from the signal source to the receiving
device. (see Note below)
• The maximum length of unshielded input and
output signal wiring should be 2 inches.
Note:
Some of Moore Industries’ instruments can be
classified as receivers (IPT 2, IPX 2, etc.) and
some can be classified as transmitters (TRX,
TRY, etc.) while some are both a receiver
and a transmitter (SPA 2, HIM, etc). Hence,
your shield ground connections should be
appropriate for the type of signal line being
shielded. The shield should be grounded at
the receiver and not at the signal source.
Electrical Connections
When installing any Moore Industries product,
always follow all local regulations and standards for
grounding, shielding, and safety.
WARNING: Terminals on this unit may be connected to
hazardous voltages. Before making ANY connections to
this unit, always remove power from the loop instrument
power terminals. or instrument power terminals.
Meter Mode:
