Interesting product, the PhD 6000 Connector for Asus MB. What do you like about it?
Some Asus boards feature a connector labeled PHD 6000. This might mean the ASUS brand and CSM MB line share the same connector but use different naming conventions like COM_DEBUG. However, it seems ASUS only mentions supporting a 3° party debug card, possibly a variant of the tl611 pro or tl631 pro. This could be useful information for troubleshooting. Regarding the origin of these boards, I only see references to color variations on AliExpress and similar sites.
I’m not sure about the precise pin configuration, but I appreciate you sharing this information. It could indeed help someone create a custom PCB to integrate a postcode display into older or budget Asus boards.
I'm exploring this to check if I can interpret the header data and apply it for post codes. So far, I've discovered an Aliexpress listing for LPC debugger cards that appear to support reading signals, along with some ASUS motherboard manuals that describe the port and its pin configuration. It looks like a UART interface, with O_COM1_TXD1 likely serving as the TX line. The term SOUTC_P80 seems to refer to port 80, which from my research is the post code debug port on the LPC interface. However, I'm unsure about its exact function—reading it as a TX line, amplifying it, or using it for clock signals. As someone new to electronics, I'm hesitant to just hook an ESP32 onto a high-cost motherboard without guidance. Any advice or suggestions would be greatly appreciated. I've also seen references to soutc_p80 in a COM IC datasheet (like NCT5104D from Nuvoton) and evidence that this chip is used in ASUS motherboards for LPC communication.
Through further investigation I discovered a comparable chip on my own board. It seems the com_debug pins are probably linked directly to the nuvoton IC (NCT6799D-R). The most effective method to determine how to use COM_DEBUG is likely to use a multimeter to test the pin connections to the IC. Once the connections are identified, you can consult the datasheet for guidance on interacting with them.
