Many modern compact Sunplus boxes use a 3.5mm mini-jack port labeled "RS232" instead of a traditional large serial port. Check your device specification for the exact pinout (TX, RX, and GND). 2. Software Checklist sunplus loader tool

Modern PCs lack native serial ports. A reliable adapter (preferably featuring a Prolific or FTDI chipset) is required to bridge your USB port to the serial cable. 2. Software Requirements

Set this to 115200 (standard for most Sunplus chips).

Sunplus Technology primarily provides tools to its direct partners and OEM clients. They do not typically offer public downloads on their corporate website.
