Flex Cables

This mainboard supports original flex cables and HML (Huaminglou) FPC, including analog triggers. Choose one of the following three installation methods for your cable.

Option

Connection method

Original flex cable

Install directly

Direct HML connection

Plug HML FPC into the 16-pin connector at the back of the mainboard, complete the solder connection, and configure the portal settings

Other flex cables

Use a contact-to-connector adapter

Option 1: Original flex cable

An original flex cable can be installed directly.

Option 2: Direct HML connection

HML (Huaminglou) FPC currently gives the best results for direct connection. Complete the solder connection below, then configure the flex cable mode and trigger directions after plugging it in.

FPC overview

The photo below shows the HML FPC. It plugs directly into the 16-pin connector at the back of the mainboard.

Required pad connection

Important

When using HML FPC, you must connect the separate pad to the left of the resistor in the red box to the resistor terminal nearest that pad.

Using the orientation in this close-up, with power disconnected, bridge the separate left pad and the resistor’s left terminal with solder. Keep the resistor in place.

Required HML connection: separate pad on the left → left resistor terminal.

Configuration after connecting

After plugging in HML FPC, connect to the configuration portal and open Configuration → System. Set the two areas marked in red below:

  1. Under Device Settings, set Flex Cable Mode to HML.

  2. Under Hardware Directions, enable Invert for both L2 and R2.

  3. Click Apply, then Save, and wait for saving to finish.

HML settings: Flex Cable Mode = HML; L2 and R2 inversion enabled. The screenshot uses the Chinese interface; the settings are described above in English.

Option 3: Other flex cables

Other flex cables can connect to the mainboard through a contact-to-connector adapter.
