DEMO MANUAL DC1223A-B
DESCRIPTION
USB to SMBus/SPI Interface
Demonstration circuit 1223A-B facilitates communication
between PC-based user interface software and Linear
Technology SMBus/I2C demonstration boards. DC1223A-B
connects to the computer via USB. It receives power from
the USB and isolates the computer ground from the SMBus/
I2C demonstration board. DC1223A-B adds to DC1223A,
the SMBus monitoring feature. The DC1223A-B can be
used in three ways, depending on the software available
for the demonstration board under evaluation (DBUE):
QuikEval Mode
QuikEval
®
mode is the easiest way to communicate with
a Linear Technology SMBus/I2C demonstration board.
However this is limited to newer battery charger demo
boards like the DC1259A. QuikEval application-specific
user interfaces are available at http://www.linear.com/
designtools/software/. Figure 2 shows an example of an
application-specific user interface for the DC1259A demo
board.
General User Interface Mode
General user interface mode is for demo boards that do
not offer customized software. The general user interface
is PC-based, and graphical, but not application specific. It
can send out discrete commands to any SMBus/I2C device
(see Figure 2 and Appendix A), supporting nine different
SMBus command protocols: Send Byte, Receive Byte, L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks and
QuikEval is a trademark of Linear Technology Corporation. All other trademarks are the property
of their respective owners.
Write Byte, Read Byte, Write Word, Read Word, Block
Write, Block Read and Block Write-Read Process calls. It
also supports additional command protocols for PMBus:
Extended Read Byte, Extended Write Byte, Extended Read
Word, Extended Write Word and Group Send. It can also
monitor the SMBus traffic of an existing communication
between a master and a slave. Contact the Linear Technol-
ogy sales department for the latest general user interface
software.
DC410 Emulation Mode (Windows XP Only)
A number of Linear Technology demonstration boards
offer software for use with the DC410 Serial Port-to-
SMBus Interface Board, e.g. DC285 (LTC1695), DC182
(LT1786F), DC286 (LTC1960), DC486 (LTC1760), DC496
(LTC4008), and DC512 (LTC4100). For these boards, the
DC1223A-B can be used to replace DC410. These demo
boards have application-specific user interface programs
but they are not part of the QuikEval software program.
These application-specific programs are available from
Linear Technology sales department.
Note: This is not a standard mode of operation. Please
see detailed Instructions in Appendix B to replace DC410
with DC1223A-B .
Design files for this circuit board are available at

QUICK START PROCEDURE (QuikEval MODE)
Figure 1. Typical Equipment Setup
Demonstration circuit 1223A-B is easy to set up to
evaluate the performance of Linear Technology SMBus/
I2C demonstration boards DC1223A-B. Refer to Figure 1
for proper measurement equipment setup and follow the
procedure below.
Note: The DC1223A-B Is powered from the Host PC
via USB.
1. Download the QuikEval software from http://www.lin-
ear.com/designtools/software/. Follow the installation
instructions carefully.
2. When prompted to plug in the demo board, first connect
the USB cable to the DC1223A-B and then connect the
Demonstration Board Under Evaluation (DBUE) to the
DC1223A-B. Power up the DBUE as recommended in
its Quick Start Guide.
3. Check to see if there are already pull-up resistors on the
DBUE. If yes, set jumpers JP1 and JP2 on DC1223A-B
to Open.
4. Check to make sure jumper JP4 is on “Direct”. JP4
should only be on “VCP” if it is doing RS232 emulation
for replacing DC410. See Appendix B for this feature.
5. The “Found New Hardware Wizard” window may popup.
If it does then choose the “Recommended” Installation.
NOTE: If Windows cannot find the device driver, then

1. Make sure you have the latest version of DC1223AB.zip.
Do not connect the USB cable to the PC yet. Install the
DC1223A-B.msi software if not already done. http://www.
linear.com/designtools/software/.
Note: For Windows Vista users, please follow the in-
structions available in the DC1223A-B.zip folder. Read
the “Installing DC1223AB_Vista.htm” file.
2. Move JP4 of DC1223A-B to Direct if it is not already
done. This is very important!
3. Download the QuikEval software from http://www.lin-
ear.com/designtools/software/. Follow the installation
instructions carefully.
4. When prompted to plug in the demo board, first connect
the USB cable to the DC1223A-B and then connect the
Demonstration Board Under Evaluation (DBUE) to the
DC1223A-B. Power up the DBUE as recommended in
its Quick Start Guide.
5. Connect the hardware the same way as shown in
Figure6.
Note: It is not necessary to use a DC486. Any SMBus
device with SCL, SDA, GND can be connected to
DC1223A-B via the P2 connector. For example you can
use a smart battery as a SMBus device as shown in
Figure 6. Smart battery is a master/slave device.
6. Launch DC1223A-B_Monitor.exe.
7. A General User Interface window appears as shown in
Figure 4. Input the slave address and the commands
to talk to the smart battery or LTC1760. 16HEX is the
slave address of the smart battery. A 16HEX device
command is the AlarmWarning() command sent to
the battery. The read word result is 00C0HEX, meaning
no alarms raised except that the battery is currently
discharging. For more information about the meaning
of device command 16HEX go to View → SBS → SBS
Table.
8. To go into SMBus Monitor mode, go to Tools → Monitor.
You will see the windows in Figure 5. For more detail
instructions go to Help → Help Topics.

DEMO MANUAL DC1223A-B
A number of older battery charger demonstration boards,
including the DC286 (LTC1960), DC486 (LTC1760), DC496
(LTC4008) and DC512 (LTC4100) used the DC410 to send
SMBus commands to/from a PC via a serial RS232 com
port. The software developed for this configuration was
based on Labview. This software is provided when you
order these older demo boards.
Please contact Linear Technology Applications if you need
a copy. However, as RS232 is disappearing, and is being
replaced by USB, the DC1223A-B replaces the DC410. The
DC1223A-B can be used to emulate a RS232 com port
for backwards compatibility with the existing application-
specific Labview software.
Note: If you don’t want to use the legacy Labview
software which requires RS232 emulation, you can
alternatively use a General User Interface(GUI) software
developed to communicate using DC1223A-B which
does not require RS232 emulation (use USB directly).
However you will be missing the user friendly interface
specific to a particular device, for example the LTC1760,
LTC4100 or LTC1960 available in the legacy Labview
program. Instead the GUI requires you to input the
parameters yourself. For the GUI program, skip the
below instructions and go to the Appendix A.
So the new configuration is a DC486 (for example) and a
DC1223A-B. The same Labview software can still be used.
However, you need to follow these steps as it involved
RS232 emulation.
Installing Software to Emulate DC410 (RS232)
1. Connect the hardware as shown in Figure 6. Do not
connect the USB port to the computer yet.
2. DC1223A-B jumper positions should be:
JP5 on “5V”
JP4 on “VCP” (Virtual Com Port)
Note: This is a very important step. When you change
the jumper to JP4, you are telling the FTDI chip to
emulate a RS232 port. If JP4 is on “Direct”, the FTDI
chip will communicate directly as a USB.
3. Install DC1223A-B.msi, but don’t run it. If you need
a copy of the software please go to http://www.linear.
com/designtools/software/.
Note: For Windows Vista users, please follow the in-
structions available in the DC1223A-B.zip folder. Read
the “Installing DC1223AB_Vista.htm” file.
4. Download the QuikEval software from http://www.lin-
ear.com/designtools/software/. Follow the installation
instructions carefully.
5. When prompted to plug in the demo board, first connect
the USB cable to the DC1223A-B and then connect the
Demonstration Board Under Evaluation (DBUE) to the
DC1223A-B. Power up the DBUE as recommended in
its Quick Start Guide.
6. Go to the computer’s device manager by choosing
(Start→ Control Panel → System → Hardware tab
Device Manager). Look at the ports (COM and LPT).
Notice the USB Serial Port (COM4). This tells you that
a Virtual Com Port now exists (the USB emulated a
RS232 com port) so that you can continue using the
legacy Labview program. See Figure 8.
7. If the RS232 com port emulated is higher than 4, please
change it to any number between 1 and 4 by right click-
ing on ports (COM & LPT), select the Port Settings tab
and select Advanced. Change the Com port number to
a number from 1 to 4. See Figure 9.
8. Launch the software for the demo board under evalu-
ation (e.g., DC486) and when prompted to enter the
RS232 com port, use the number you obtained from
step 8. If you need a copy of the software please contact
Linear Technology Sales Department. For DC486, you
will need dc486v2.exe. See Figure 10.
