Introduction, Installation, and Setup
1-1
Introduction
1.1 Introduction
The MSP-GANG430 is an MSP430 device programmer that can program up
to eight MSP430 flash devices at the same time. The MSP-GANG430
connects to the host PC using a standard RS232 serial connection. The
MSP-GANG430 provides flexible device programming options as described
in Chapter 2.
The MSP-GANG430 is not a gang programmer in the traditional sense; there
are not eight sockets provided to program the target devices. Instead, the
MSP-GANG430 is designed to connect to the target devices in-circuit (i.e., the
target devices are mounted in the customer’s final circuit/system). The
MSP-GANG430 accesses the target devices using connectors to the JTAG
signals.
Chapter 6 contains a schematic that documents how the signals from the
MSP-GANG430 can be brought out to each of the target devices via an
MSP430-standard JTAG connector. The circuit could easily be modified to
connect the signals to the target device pins directly (via a socket) if a
traditional gang programmer was desired.
The MSP–GANG430 is provided with an expansion board that implements the
interconnections between the MSP–GANG430 and multiple target devices.
Eight cables are provided that connect the expansion board to eight target
devices (via a JTAG connector).

1.2 Software Installation
To install the MSP-GANG430 software:
1) Insert the MSP430 CD-ROM into the CD-ROM drive of the computer. The
setup routine automatically opens the default browser of the computer and
displays the MSP430 start page. Alternatively, open the file index.htm
located in the root directory of the CD-ROM using a browser. The MSP430
start page is displayed in the browser window.
2) Select Tool Software
3) Select MSP-GANG430 Gang Programmer
4) Select Save this program to disk under the File Download options and click
OK. A Save As dialog is displayed.
5) Using the Save As dialog, save the GANG430_Rxxx.exe program to the
computer. Make a note of the directory path to this file.
6) Navigate to this file (GANG430_Rxxx.exe) and execute it. A welcome
message is displayed on the screen.
7) The setup program guides you through the installation process. Follow the
setup instructions on the screen.
Software Installation
8) On completion of the setup program execution, the MSP-GANG430
program icons are created in the selected folder. Click on the GANG430
Read Me First icon to obtain important information about the
MSP-GANG430 hardware and software.
9) The appropriate program group and icons are added to the Windows
program manager.
10) To start the MSP-GANG430 software, click the GANG430 icon in the
selected program group (the default program group is ADT430).
1.3 Hardware Installation
To install the MSP-GANG430 hardware:
1) Connect the MSP-GANG430 to the serial port (COM1–COM4 or
extension board) of the PC using the 9-pin SUB-D connector.
2) Connect an external power supply to the MSP-GANG430. The voltage of
the power supply must be between 8 V and 15 V dc and must be capable
of providing a minimum current of 300 mA. The center post of the power
supply connector on the MSP-GANG430 is the positive voltage terminal.
The power supply connection status is indicated by the yellow system LED
on the MSP-GANG430.
3) The expansion board should be attached to the 25-pin SUB-D connector
on the MSP–GANG430. It provides connectivity for up to eight targets, via
the included eight 14-pin cables. The target MSP430 flash devices can be
in standalone sockets or can be on an application’s PCB and are accessed
via the JTAG signals.
Introduction, Installation, and Setup
1-3
Hardware Installation
Note: Maximum Signal Path Length: 60 cm
The maximum length of the signal path between the 25-pin SUB-D connector
on the MSP-GANG430 and a target device is 60 cm.
4) The MSP–GANG430 provides the selected power supply voltage V
(VCC_MSP on pins 7 and 14 of the 25-pin SUB-D target connector; pin
2 on the 14-pin cable) to the target devices in application PCBs. A maximum total current of 150 mA can be provided by the programmer to the
targets.
5) When an external supply voltage V
should also be fed into the sense input pin (MSP_VCC_IN on pin 15 of the
25-pin SUB-D target connector; pin 4 on the 14-pin cable) of the
programmer. This connection allows the integrated level shifters to match
the target JTAG signal levels with the external supply voltage.
When an external supply voltage is used for the target systems, it is very
important to disconnect VCC_MSP from the targets to avoid power supply
conflicts that could potential damage the MSP-GANG430 and the targets.
Connect the external supply voltage to MSP_VCC_IN.
It is not possible to use the MSP-GANG430 with targets powered by the
MSP-GANG430 and with targets powered by an external supply
simultaneously.
