Programmatically Triggering Hot-Swap on the DFR1168 USB4 to PCIe Docking Station
Philip.Lindsay 2026-07-07 11:05:00 92 Views1 Replies I'm looking for the correct way to trigger the DFR1168's hot-swap function from an external control PCB. Specifically, I'd like to know whether toggling J3/J4 is the recommended approach, how long they should remain disconnected, and if there's any onboard header or signal available for external control instead of modifying the jumpers.
thanks so much

Hi, toggling J3/J4 off and on will be recognized as a valid hot-swap event. We recommend a delay of around 5 seconds.
There is no dedicated external control header. You will need to run wires from the J3/J4 switch pads or remove the switches and control them via an external relay.
