Projectors and screens
Polling Sequence: 5 queries (power, A/V mute, freeze, source, error), each 500 ms on / 3000 ms off, so one query every 3.5 s and a full loop every 17.5 s. It starts at boot from the saved init state. In standby the L260F answers only PWR?; the other four return ERR, so those values go stale. Warm-up 30 s is Epson's PWR ON time for this model; cool-down 20 s is a typical value.
Shure ULXD4D: automatic mic EQ
Tesira asks < GET 0 TX_TYPE > on connect and at boot, and again whenever a transmitter's mute button is released. Each reply picks the matching Uber Filter for that channel: Handheld → HH - 7, Bodypack → Lav - 7, Boundary → Boundary - 7, Gooseneck → Goose - 7. The patterns start with ?LXD, so QLX-D transmitters match too. An unknown or switched-off transmitter matches nothing, and the channel keeps its last EQ. Untick the box to see the design work without unsolicited reports.
Levels
Ramp rate and the −40 to +12 dB range are for the demo. The real rate and limits come from the Level blocks.
