of the monitor. One of the two micro-controllers is located on the G-sync module, and the second micro-controllers is
located on the base board.
3.1.3 Required Hardware
The hardware required to update the code on the two micro-controllers is a TI-MSP430 USB debug interface.
This device can be ordered from TI at http://www.ti.com/tool/msp-fet430uif.
Figure: MSP-FET430UIF with Cables
In order to connect the base board micro-controllers, the standard ribbon cable that comes with MSP-FET430UIF
can be used. In order to connect the MSP-FET430UIF to the P2324 G-SYNC module, a special connection cable
muse be used. This connection cable is provided by NVIDIA and should have come with your G-SYNC module. One
end of that cable will connect to the MSP-FET430UIF programmer, and the other end connects to the G-SYNC
module and looks like this:
