Hello,
This is a follow-up to this thread which has been locked when I could not access the setup to to confinement measures where I live.
I tested again the setup and, again, forcing signal detect to HIGH on channel A causes channel B TX to lock. However, when I deassert signal detect HIGH on channel A, channel B TX unlocks immediately.
I also tried this: Starting from my initial workaround (routing of channel B RX to channel C TX), where channel B TX is locked, I force signal detect high on all four channels of the quad. Then, I change the crosspoint to the initially intended configuration (A RX fans out to A, C and D TX, C RX routed to B TX ; channel B TX is still locked). Finally, I deassert signal detect high on all four channels of the quad. At this time, channel B TX is unlocked.
So the workaround (asserting signal detect high while changing crosspoint configuration, then deassert signal detect high) does not work in my case. Leaving signal detect high could be a workaround, but then I lose the actual information of the signal detect status.
Any advice would be appreciated.
Regards,
