Installing the Hardware

1.2 Installing the Hardware

To install the programming adapter hardware, perform the following steps:

1)Using the 9-pin SUB-D connector, connect the programming adapter to the serial port (COM1−COM4) of the PC.

2)Connect an external power supply to the programming adapter. The voltage of the power supply must be between 14 V and 20 V dc and must provide a minimum of 200 mA of power. The center terminal of the supply connector at the programming adapter is the plus pole.

3)The red LED on the programming adapter lights if the power supply is properly connected. If the LED does not light and the power supply is properly connected, check the F1 fuse on the programming adapter printed-wire board (PWB).

4)The MSP430 devices, in a socket or on a PWB, should be connected to the programming adapter through the 14-pin cable.

The programming adapter provides the selected supply voltage VCC at pin 14 of the 25-pin SUB-D connector, or at pin 2 of the 14-pin connector to

supply the MSP430 device. The signal name is VCC_MSP.

If an external supply voltage VCC is used for the MSP430, the internal voltage VCC_MSP must be set to the same voltage level.
