Introduction
This is the users’ manual for Moore Industries’
SDY PC-Programmable Signal Isolator/Converter.
It contains all of the information that is needed
to congure, install, operate, maintain, and
troubleshoot the SDY. If you require additional
assistance, call one of our STAR Centers (for
Service, Technical Assistance, and Repair) to talk
with a technician or engineer.
The following guidelines are used in this manual:
WARNING - Hazardous procedure or condition that
could injure the operator.
Caution - Hazardous procedure or condition that
could damage or destroy the unit.
Note - Information that is helpful for a procedure,
condition, or operation of the unit.
The SDY
The SDY is a versatile, 2-wire (loop-powered),
PC-Programmable Signal Isolator/Converter that
accepts current or voltage input and provides an
isolated, proportional 4-20mA output. See Figure 1
for a list of accommodated input types.
Typical uses for the SDY include:
• Isolating Signals to stop erratic process
measurements caused by ground loops
• Converting Signals so eld instruments can
interface directly with indicators, recorders,
DCS’s, PLC’s, and PC-based SCADA systems
• Diverting Signals so the output from one
transmitter can be sent to two separate locations
• Protecting Equipment and Signals by eliminating
common electrical paths
• Boosting Signals to enable more instruments to
be added to an overburdened loop
• Solving the “Bucking Power Supplies” problem
that occurs when a 4-wire transmitter and a
DCS both try to power the same process loop
Figure 1. Compact, yet powerful, the SDY transmitter features programmable inputs and a trimmable output to boost accuracy.

Installing the
Conguration Software
Refer to Table 1 for the equipment needed.
1. Insert the Moore Industries Interface
Solution PC Conguration Software CD
into the CD drive of the PC. Access the
CD and open the SDY SIY TDY TRX
TRY 64 bit PC Conguration software
folder.
2. Double-click the installation program
located in the folder. Follow the
prompts to correctly install the program.
Once the Conguration Program is installed on the
PC, the SDY can be connected to equipment to
simulate input and monitor output. You can then
change the transmitter’s operating parameter
CAUTION:
Any time a connected SDY is “programmed”
by downloading a Conguration File into memory,
ALL of the conguration parameters resident
in the transmitter memory at the time of the
download are OVERWRITTEN. This includes
things like: tag name, calibration date, trim values,
etc.
Conguration
Conguring the SDY consists of:
1. Checking to verify that the unit ordered is in fact
the one received and that it has been correctly
calibrated by the factory according to the order.
2. Installing the SDY Conguration Software by
following the directions on the label.
3. Connecting the SDY to a PC and test setup,
running the SDY PC Conguration Program to
check for correct unit tagging, input type and
range settings, and output zero/span trim.
Prior to shipment, our team of skilled technicians
subjects every SDY to rigorous testing. Every
product Moore Industries manufactures, sells, and
services is guaranteed to meet the strict quality
standards that our company demands.
Even if a unit has been congured to your
specications by the factory (factory calibration),
it is a good idea to perform a bench check. In
addition to providing a safe means of uncovering
any unit damage that may have occurred during
shipping, the procedures a󰀨ord the user the
opportunity of becoming familiar with SDY operation
in a testing environment that is separate from the
intended process or application.
Note:
The procedures in this section should be carried
out in an environment considered appropriate for
the general testing of electronic equipment, rather
than in the eld. Use a technician’s bench or
similar, lab-type environment.

It is possible to run the SDY Conguration program
without actually connecting a unit to the PC, but you
will be unable to set a custom linearization table.
This makes it easy to devise and download a single
conguration to several SDY. To do this, save
the Conguration File to disk, connect the units in
succession, and download the same le to each.

Figure 3. Setting SDY Parameters Using the Conguration Screen
Using the SDY PC Conguration
Program
Once the software has been installed on your hard
disk:
1. Run the PC Conguration Program.
2. Set the values as appropriate for your
SDY application in the various elds of the
Conguration Screen shown in Figure 3.
Note:
If you are building a Conguration File
without a SDY connected, the “SDY Status”
section of the screen will be blank, and the
“Communication” indicator will show steady
ON (as opposed to blinking).
During setup, the SDY tests the availability
of COM Ports 1 through 4 in your system.
The rst available COM port is designated
for SDY communications and is noted
on the Conguration Screen. Your SDY
communications cable must be connected
to this port.
To connect the SDY to a port other than
the default described above, disconnect
the transmitter, then change the default
selection with the pull down menu. Next
reconnect the SDY communications cable.
3. When the Conguration File shown on the
screen has been modied for your intended
application, click the “Stop” button to stop
measurement.

3. Click on the “Quit File” button.
The Conguration Screen will change to show
the parameters entered into the retrieved le.
The parameters can now be edited and/or
downloaded into the memory of a connected
SDY.
Saving the SDY Conguration
File to Disk
This is an optional procedure. You do not have
to save the le to disk in order to download the
le into SDY memory. Use this procedure to save
information on the conguration of your SDY for
downloading into other SDY transmitters, or for
record-keeping purposes, etc.
To save the SDY conguration les to disk:
1. Click on the “File” button. This brings up an
Explorer-like window on the left area of the
screen.
2. Enter the le name that you wish to save in
the “Selected File Name” box.
This will cause the “Prog” button to become
available. Click “Prog”, and the software will
download the parameters on the PC into the
nonvolatile memory of the connected SDY.
Status of the downloading is shown in the
upper left corner of the screen. When
completed, the program beeps.
Note:
Changing the settings on the Conguration
Screen does not change SDY parameters
until the Conguration File is downloaded to
SDY memory as described in Step 3 above.
Any time the SDY settings are changed, the
conguration date will change to reect the
date the new settings were entered.
Printing Saved Congurations
1. Click on the “File” button. This brings up an
Explorer-like window on the left area of the
screen.
2. Navigate to the save le you want to print and
click on it.
3. Click on the “Print” button.
Note:
Printing saved congurations must be done
when the Explorer-like le window is up.

Loading a Conguration File From
a Connected SDY
To edit or view a Conguration File in the nonvolatile
memory of a connected unit, you can use the “Get
Setup” function of the Conguration program.
Note:
Whenever a unit is correctly connected to your
PC, the “SDY Status” section of the Conguration
Screen will show the conguration data already
stored in unit memory.
To load a conguration le from a SDY, connect a
powered SDY and click “Get Setup”.
The editable elds of the SDY Conguration Screen
will change to match the data shown in the “Status”
portion of the screen.
Setting Output Damping
To lessen the impact of your sensor’s step increases
and decreases, you may want to set the damping
time, which will cause the SDY to average out
uctuations over the set amount of time.
Setting the damping time is simple; simply click
on the damping value bar under the “Output”
portion of the screen (in the bottom-right corner),
or click on the box to the right of the
“Damping(sec)” area and type in a number
between 0 and 20.032. This number is the number
of seconds that the sensor’s value will be
averaged over.
Trimming SDY Output
The SDY has a function that allows precise control
over its output. Note that to activate this function, a
unit must be connected in the setup to a current
meter, as shown in Figure 2.
To trim SDY output:
1. Set all unit parameters on the SDY
Conguration Screen as required for your
intended application. Click “Stop” to stop
measurement.
2. Click “Out Trim”.
3. Select and move the “Output Zero” or the
“Output Full” slide bar to adjust the SDY output.
Monitor the output with a calibrated current
meter or with a voltmeter measuring the drop
across a precision, 250 Ohm resistor
(see Figure 2).
4. When both zero and full scale have been
adjusted to satisfaction, press “Quit Trim”, then
“Prog” to program the SDY with the new trim
values.
Note:
Changing the settings shown on the screen in
“Trim” mode DOES NOT CHANGE THE UNIT’S
OPERATING PARAMETERS, it only updates
the screen. The settings are saved to nonvolatile
memory by using the “Prog” function.
The “SDY Status” area of the
Conguration Screen will reect the new
output settings being downloaded into unit
memory.
