    Requires MXWAPT GUI "Preferences" tab "Mute Preference" set to "External Mute".
    1. User pushes Mic button → APT sends < REP 1 BUTTON_STS ON >
    2. Control System sends command to Mixer to unmute channel 1
    3. Mixer confirms unmuted to Control System
    4. Control System sends < SET 1 LED_STATUS OF ON > (Red off, Green on for Mic #1)
    5. User releases button → APT sends < REP 1 BUTTON_STS OFF >
    6. Control System sends command to Mixer to mute channel 1
    7. Mixer confirms muted to Control System
    8. Control System sends < SET 1 LED_STATUS ON OF > (Red on, Green off for Mic #1)
  note: Switch Behavior (toggle vs latching) determined by Crestron/AMX code when using External Mute.

Notes

Channel number x in commands is ASCII 1-8. Using 0 reports all channels. All messages are ASCII with angle-bracket delimiters < >. yyyyyyyy placeholders are 31-character strings for device/channel names. Special battery codes: 65532=wall wart charger power, 65533=on charger/not charging, 65534=calculating run time/fully charged, 65535=transmitter off. LED state values: ON=On, OF=Off, ST=Strobe, FL=Flash, PU=Pulse, NC=No Change. Metering minimum interval is 100ms, off by default. Flash auto-off after 60 seconds. Codes 255, 254, 253, 252 are special codes for 3-digit numbers; 65535, 65534, 65533, 65532 are special codes for 5-digit numbers — indicate device unavailable.
