DC1223A-B DC1223A-B ear Tech SM Bus/ I connects to the computer via U SB. It receives pow er f rom the U SB and isolates the computer ground from the SM Bus/ 2C demonstration board. DC1223A-B DC1223A-B adds I to DC1223A DC1223A the SM Bus M onitoring f eature. The DC1223A-B DC1223A-B can be used in three w ays, depending on the softw are available f the demonstration board unor der evaluation (DBU E): QuickEval mode. Q uickEval mode is the easiest w ay to communicate w ith a Linear Technology SM Bus/ 2C I demonstration board. H ow ever this is limited to new er Battery Charger demoboards like the DC1259A DC1259A. Q uickEval application specif user interf ic aces are available at http: /w w w .linear.com/designtools/ tw are/ / sof . Figure 2 show s an example of an application specif ic user interf for DC1259A DC1259A demo board. ace D C410 Emulat ion mode. A number of Linear Tech demonstration boards of softw are for use w ith the fer DC410 DC410 Serial Port-to-SM Bus Interf ace Board, e.g. DC285 DC285 (LTC1695 LTC1695), DC182 DC182 (LT1786F LT1786F), DC286 DC286 (LTC1960 LTC1960), DC486 DC486 (LTC1760 LTC1760), DC496 DC496 (LTC4008 LTC4008), and DC512 DC512 (LTC4100 LTC4100). For these boards, the DC1223A-B DC1223A-B can be used to replace DC410 DC410. These Demo Boards have application specif user interf ic ace programs but they are not part of the Q uickEval sof are program. tw These application specif programs are available from ic Linear Technology sales department. N O TE. This is not a standard mode of operation. Please see detailed Instructions in Appendix A to replace DC410 DC410 w ith DC1223A-B DC1223A-B . General U ser I erf nt ace mode.

Pow er up the DBU E as recommended in its Q uick Start Guide. USB CABLE TO HOST PC DC1223 DC1223 3. Check to see if there are already pull up resistors on the DBU E. If yes, set j umpers JP1 and JP2 on DC1223A-B DC1223A-B to O pen. 4. Check to make sure j umper JP4 is on "Direct". JP4 should only be on "VCP" if it is doing R S232 emulation f replacing DC410 DC410. See Appendix A for this or f eature. 5. The "Found N ew H ardw are W izard" w indow may pop up.

The softw are developed for this conf iguration w as based on Labview . This softw are is provided w hen you order these older demoboards. Please contact Linear Tech Applications if you need a copy. H ow ever, as R S232 is disappearing, and is being replaced by U SB, the DC1223A-B DC1223A-B replaces the DC410 DC410. The DC1223A-B DC1223A-B can be used to emulate a R S232 com port f backw ards compatibility w ith the or existing application-specif Labview sof are. ic tw N O TE. If you don' w ant to use the legacy Labview sof are w hich t tw requires R S232 emulation, you can alternatively use a General U ser Interf ace(GU I) sof are developed to communicate using DC1223A-B DC1223A-B tw w hich does not require R S232 emulation (use U SB directly). H ow ever you w ill be missing the user f riendly interf specif to a particular device, f ace ic or example the LTC1760 LTC1760, LTC4100 LTC4100 or LTC1960 LTC1960 available in the legacy Labview program. Instead the GU I requires you to input the parameters yourself For the GU I program, skip the below instructions and go to the . Appendix B. So the new conf iguration is a DC486 DC486 (f example) and or a DC1223A-B DC1223A-B. The same Labview sof are can still be tw used. H ow ever you need to f ollow these steps as it involved R S232 emulation. I STALLI G SO FTW ARE TO EM ULATE DC410 DC410 (R S232) N N 1. Connect the hardw are as show n (Figure 3). Do not connect the U SB port to the computer yet. 2. DC1223A-B DC1223A-B j umper positions should be: ­ JP5 on "5V" ­ JP4 on "VCP" (Virtual Com Port). N O TE. This is a very important step. W hen you change the j umper to JP4, you are telling the FTDI chip to emulate a R S232 port. IfJP4 is on " Direct" the FTDI chip w ill communicate directly as a U SB. , 3. Install DC1223A-B DC1223A-B.msi, but don' run it. If you need a t copy of the softw are please contact Linear Technology Sales Department. N O TE.

Connect the U SB cable to the PC now . W ith JP4 on "VCP", you may need to install a driver on your computer. If prompted to install the driver (see Figure 4) f U SB or Serial, select "Install from a list or specif location (Advanced)". Type in the path for ic "C: \Program Files\LTC\DC1223A-B DC1223A-B\driver". If asked to overw rite driver, click "Yes". You do not need to launch DC1223A-B DC1223A-B. 5. If prompted to install the driver for U SB Serial Port, f ollow step 4. O therw ise go to the next step. 6. Exit DC1223A-B DC1223A-B if it is launched. 4 DC1223A-B DC1223A-B Figure 3.

Go to the Computer' Device manager by choosing s (Start Control Panel System H ardw are tab Device M anager). Look at the Ports (CO M & LPT). N otice the U SB Serial Port (CO M 4). This tells you that a Virtual Com Port now exists (the U SB emulated a R S232 com port) so that you can continue using the legacy Labview program. See Figure 5. 8. If the R S232 com port emulated is higher than 4, please change it to any number betw een 1 and 4 by right clicking on Ports (CO M & LPT), select the Port Settings tab and select Advanced. . Change the Com port number to a number from 1 to 4. See Figure 6. 9. Launch the softw are f the demo board under or evaluation (eg. DC486 DC486) and w hen prompted to enter the R S232 com port, use the number you obtained f rom step 8. If you need a copy of the sof are tw please contact Linear Technology Sales Department. For DC486 DC486, you w ill need dc486v2.exe. See Figure 7. 5 DC1223A-B DC1223A-B Figure 5. D evice M anager Figure 6. Change t CO M port t U SB is emulat he hat ing Figure 7.

It is not necessary to use a DC486 DC486. Any SM Bus device w ith SCL, SDA, GN D can be connected to DC1223A-B DC1223A-B via the P2 connector. For example you can use a Smart Battery as a SM Bus device as show n in Figure 8. Smart Battery is a M aster/ Slave device. 5. Launch DC1223A-B DC1223A-B_M onitor.exe. 6. A General U ser Interface w indow appears as show n in Figure 9. Input the Slave Address and the commands to talk to the Smart Battery or LTC1760 LTC1760. 16H EX is the Slave address of the Smart battery. A 16H EX device command is the AlarmW arning() command sent to the battery. The read w ord result is 00C0H 00C0H EX , meaning no Alarms raised except that the battery is currently discharging. For more inf ormation about the meaning of device command 16H EX go to View SBS SBS Table. 7. To go into SM Bus M onitor mode, go to Tools M onitor. You w ill see the w indow s in Figure 10.
