Operating Instructions
Test Equipment Required Personal Computer with Windows later O/S) parallel port. Power Supply, 500mA. Oscilloscope, Digital sampling, 4-channel High Accuracy (e.g., HP34401A equivalent) Test Steps Software setup Close open Windows application programs. Insert "SMS66EV Software" into CDROM drive. Follow installation instructions, rebooting computer when prompted. After computer reboots, perform full power shutdown install Dongle. Dongle installation Caution: apply power sources SMS66 evaluation board while Dongle connected board. Remove existing cabling from computer's parallel port (LPT1). Connect Dongle parallel port. Insert Dongle cable onto SMS66 Evaluation board connector (pin board corresponds white wire with orange stripe, also SMX3200 Dongle Info Page SMX3200 Data Sheet ROM, site document package). Reapply power computer. After computer restarts, open `SMS66 Programmer' application program click `Standard Settings' button. dialog shown Figure will appear screen. Note: SMS66 device registers preconfigured with Default Configuration Settings shown SMS66 data sheet. Settings specific SMS66EV evaluation included Intel format file located programmed into SMS66 samples shipped with SMS66EV kit. Optional: Click `HEX' folder icon load `SMS66EV.Default Hex' file from CD-ROM drive. Optional: Click `Write Config' button. This configures SMS66 registers sequence DC-DC converters monitor DC-DC converter output voltages, etc. Hardware Note: Dongle interface generates impedance source power program SMS66. Ensure jumpers their correct position displayed Figure Connect power source EVAL board follows: Connect terminal supply `GND' connect pin. Connect terminal supply `5VIN' connect pin. Switch power source HEALTHY (D13) indicates that DC-DC converters enabled within programmed tolerances. Explore SMS66 features changing many configurable parameters. Confirm programmed settings agree with actual measurements. Observe functionality SMS66 varying supply voltage changing states input signals. Only Operation: SMS66 Eval Board designed operate from because DC-DC Converters populated boards specified operate from inputs. order operate board from only, DC-DC converters Eval should removed populated with input devices. Also, jumpers through must moved from positions. Then, connect jumper (VREF_IN) from position VDD_CAP. Furthermore, connect jumper across test pins labeled `VDD' `VDD_CAP' located nearby SMS66 Socket.

Comments Precautions
Ensure that SMS66 device securely seated 48-pin TQFP Spring-Loaded Socket correctly oriented indicated block dot/void part marking orientation. Occasionally, socket lose contact from oxidation. With power turned-off, reseat device pressing down releasing socket. SMS66 precision integrated circuit requiring certain attention spent with regards component selection printed circuit board layout ensure greatest possible performance. Since SMS66 does measure each voltage differentially, special attention must paid where part's connected. measurements best made load power supplies, should also connected power supply return load. Accurate measurements supplies possible laying such that large copper trace from each individual supply voltage return load) routed separately directly SMS66 joined together there `star ground'). large trace ensures that currents flowing between supply returns does result voltage drop occurring between point load single point connection made SMS66 pin. Choose general purpose ceramic capacitor CAPx filtering function, making sure these components located close SMS66 possible. Although accurate internal voltage reference available, ±0.2% tolerance possible using external ±0.1% reference. Locate this device nearby SMS66 keep ground connection from reference short direct SMS66.
