Introduction

General This publication provides instructions for use of the optional communications card
feature for the Micro-AT Source-Transfer Control (Catalog Number Sufx“-Y8”). See
Figure1. This feature permits local uploading of the Micro-AT control’s “events,” operat-
ing characteristics and operating parameters, digital input and output states, and
messages explaining why the automatic-transfer “ready” indicating lamp isn’t lighted.
This feature also allows local downloading of the user’s standard operating parameters
to the Micro-AT control.
To use the communications card feature, you’ll need the following:
• An IBM PC AT or compatible computer using Intel’s 80386 microprocessor, or higher.
The computer must have a minimum of 2MB of memory, a CD-ROM drive, and a hard
disk drive with at least 2MB of free space. The computer must operate under Micro-
soft Windows™, Version 3.X, Windows® 95, Windows® 98, Windows® 2000,
Windows® NT, Windows® XP, or Windows® 7-32-Bit.
• To use Windows® 764-Bit Operating System, the system version must be Profes-
sional or Ultimate. Both include XP Mode, which is required to use the Micro-AT
Communications Card. Also note that the XP Mode virtual machine must be cong-
ured to use a serial port on the computer (if one exists), or a USB-to-Serial adapter,
and the USB-to-Serial driver must be installed on the XP Mode virtual machine.

Safety Information

Using the Communications Card
Before proceeding, refer to Quick-Start Programming Instruction Sheet 515-530 or
Instruction Sheet 515-500 or 515-600 for instructions on eld programming and opera-
tion of the Micro-AT Source-Transfer Control.
Installing Matlink™
on Your Computer
Hard Drive
NOTICE
Matlink™ communication software, is available for download at www.sandc.com>
Support> S&C Automation Customer Support Portal. If you need assistance, please
contact [email protected] or phone [phone].
Go to the S&C Automation Customer Support Portal, open the Matlink Workspace, and
download the appropriate Matlink Software installer to your desktop. Unzip the down-
loaded folder, and save the folder contents to your desktop. Double click the program
INSTALL.EXE that you saved on the desktop. This will install Matlink Software on
your computer.
To start Matlink, click your Start button and select All Programs. Open the Matlink
V2.xx folder and double click the Matlink program inside the folder.
Running Matlink ÇCAUTION
The steps which follow describe the procedure for running Matlink with a Micro-AT
Source-Transfer Control connected to your personal computer. Matlink can also be
run—and congurationsdcreated—without a Micro-AT control connected to the
personal computer. If you wish to create a conguration(s) for later downloading,
proceed to “APPENDIX” on page 16.
Step 1
Place the manual/automatic operation selector switch on the Micro-AT Source-Transfer
Control in the “MANUAL” position.
Step 2
Decouple each operator from its interrupter switch—changing the Micro-AT congura-
tion might cause a temporary service interruption. Refer to the S&C instruction sheet
furnished with the pad-mounted gear, metal-enclosed switchgear, or Vista® Underground
Distribution Switchgear or, in weatherproof enclosure applications, the S&C instruction
sheet furnished with the switch operators.
Step 3
Loosen the screw which retains the hinged lower panel of the Micro-AT control and swing
open the lower panel. See Figure1 on page 4. (In pad-mounted gear which was originally
furnished with a Type AT-12 Source-Transfer Control, loosen the two screws which retain
the door assembly of the Micro-AT control and swing open the door assembly.)
Step 4
With your computer off, connect the communication cable between the serial port of the
computer and the communication port of the Micro-AT control. A USB-to-Serial adapter
is required if your computer does not have a Serial port.
dA configuration consists of the settings of the Micro-AT control, which include its operating characteristics
and its voltage-, current-, and time-related operating parameters.

Step 5
NOTICE
Help screens have been created and are viewable any time Matlink is running.
Turn on the computer.
Double-click on the MATLINK icon. Or open the File Manager and select MAT-
LINK; then highlight and select MATLINK.EXE.
The Matlink application will appear as shown below.
Step 6
To establish the communication link between your computer and the Micro-AT control:
(a) Highlight and select Communications on the menu bar. A pop-up menu will
appear listing communications options as shown below.
Using the Communications Card
S&C Instruction Sheet 515-506 7

(b) Select the bit rate and port by highlighting and selecting Settings. A dialog box will
appear listing bit rate and port options as shown below. Select 19200 bps and the
appropriate serial port. If you experience data transfer problems, both the Micro-
AT and Matlink communication settings should be set to 9600 bps.
(c) Verify that the status window shows a changing clock display as shown below—
indicating that communication with the Micro-AT control has been established. If a
problem is encountered in establishing communication, an appropriate dialog box
will be displayed explaining the problem. Should you need to change the bit rate at
the Micro-AT control, refer to Quick-Start Programming Instruction Sheet 515-530
or Instruction Sheet 515-500 or 515-600 for details.
NOTICE
A help screen is available for communications and troubleshooting.
Using the Communications Card

What Matlink Can Do Using Matlink, you’ll be able to view the following:
• The settings of a Micro-AT control, which include its operating characteristics and
voltage-, current-d, and time-related operating parameters;
• System voltage and currentdvalues;
• The status of the Micro-AT control, its associated switch operators, and remote
supervisory functionsf, and
• The event log of the Micro-AT control.
You’ll also be able to save to le the Micro-AT settings and the event log. You’ll have
the capability of changing most settings of the Micro-AT control, either from your com-
puter or from a le.
If necessary, you can use Matlink to view messages explaining why the automatic-
transfer “ready” lamp on a Micro-AT control isn’t lighted. And when troubleshooting
data-line circuit problems, you’ll be able to examine the status of digital inputs to the
control and digital outputs from the control.
The event log is available in two formats, *.log and *.csv. The conguration data is
also available in two formats, *.cfg and *.txt. The *.log le can be viewed using an
application such as Microsoft®Notepad or Microsoft®Word.

Using the Communications Card
Viewing Micro-AT
Control Settings NOTICE
For new Micro-AT installations: Before proceeding, you’ll need to normalize
the left and right sources to compensate for any output-voltage magnitude and/or
phase-angle unbalance between the voltage-sensing devices on that source. You’ll
also need to set the base voltages on phase 2 of the left and right sources. Each
source should be in its known normal state during the execution of the normalizing
and set base menu items so that any unusual conditions are calibrated out. Refer to
Quick-Start Programming Instruction Sheet 515-500 or 515-600 for details.
Normalizing the sources and setting the base voltages must be performed at the
Micro-AT control. These functions cannot be performed using Matlink.
In the steps which follow, you’ll be viewing the settings of items listed in the Congura-
tion, Voltage, Current, and Time data windows. You can also access these items by
highlighting and selecting Window on the menu bar, as shown below, and then highlight-
ing and selecting the appropriate data window.
If any of the eld adjustable items need to be changed, refer to “Changing Micro-AT
Control Settings” on page 13.
Step 7
Click on the Cong button bar. The Conguration data window will appear, similar
to that shown below.

positive-sequence voltages, and negative-sequence voltages after normalizing are
displayed.
The eld adjustable items in the Voltage data window which can be changed using
Matlink include Loss of Source Level, Return of Source Level, Unbalance Level,
and Overvoltage Level.
Step 9
If Lockout Option has been factory-set for “Internal,” click on the Current button bar.
The Current data window will appear, similar to that shown below.
The Lockout Level is eld adjustable using Matlink.
Step 10
