3.2 How to Determine If Your Hardware is Based on eZ430
• Check the installed tool drivers by using the Windows Device Manager (see Figure 5). eZ430 tools
enumerate as HID (Debugger port) and CDC (Backchannel UART) devices.
• Check the Experimenter Board to find out if it is based on an eZ430 tool (see Figure 4). If it is based
on an MSP430F1612 and a TUSB3410, it is an eZ430 tool.

3.3 Signal Connections for In-System Programming and Debugging
For details about the hardware connections of all debug probes refer to the "Signal Connections for In-
System Programming and Debugging" section of the MSP430 Hardware Tools User's Guide.
3.4 Using the Power Supply Feature of the eZ-FET and eZ-FET Lite
The eZ-FET and the eZ-FET Lite only support a fixed voltage power supply. The maximum supply current
is 75 mA. For more details, refer to the specific LaunchPad or experimenter board user's guide.
NOTE: These debug probes do not support externally powering of the device while debugging – if
an external voltage is needed for stand-alone testing, the eZ-FET emulation section should
not be connected through USB. If both external power and the USB power are connected,
there could be a conflict that can damage the device.
3.5 Using the Power Supply Feature of the MSP-FET430UIF and MSP-FET
All MSP debug probes can supply targets with up to 100 mA through pin 2 of the 14-pin JTAG connector.
NOTE: The target should not consume more than 60 mA at peak current, as it may violate the USB
specification. Details can found on www.USB.org.
Example: If the target board has a capacitor on the V
CC
line with a capacity of more than 10 µF, it may
cause an inrush current during capacitor charging that may exceed 60 mA. In this case, the current should
be limited by the design of the target board, or an external power supply should be used.
