# UNRESOLVED: no settable parameters beyond discrete actions

Events

# UNRESOLVED: no unsolicited notifications described in source
# System boot messages are emitted on the SERVICE ONLY minijack during power on/off - ignore.

# UNRESOLVED: no safety warnings or interlock procedures in source

Notes

Command format: 4-char command + 4-char parameter (left-aligned, space-padded) + CR (8 ASCII codes total).
Parameter chars: 0-9, x, blank, ? (x is wildcard for any digit; ? is query).
"ERR" returned when parameter out of range.
Connection drops after 3 min of no communication.
Do NOT select Telnet or SSH service for IP control — service must be "None".
Power On (POWR1___) requires "Initial Setup" → "Quick Start Mode" = On. If Quick Start is Off and "Wake on Wi-Fi/LAN" is Enable, power on is possible via Wake-on-LAN magic packet.
When Quick Start is Off and the display is off, only POWR1___ works at 9600 baud; after sending it, the baud rate reverts to the prior setting.
The SERVICE ONLY minijack outputs system boot messages during power on/off — ignore these.
BAUD command switches RS-232C between 9600 and 115200.
Wait for OK response before sending the next command (no concurrent commands).
