Variables

# No settable parameters beyond discrete actions - all parameterized controls are captured in Actions.

Events

# UNRESOLVED: no unsolicited notification events described in source

Macros

# UNRESOLVED: no multi-step sequences described in source

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source mentions "hard power" vs "soft power" distinction but no
# explicit safety interlock procedures or power-on sequencing requirements stated

Notes

Command format: Binary hex protocol. Set commands are 8 bytes; Get commands are 4 bytes. Last byte is checksum chosen to force total to 100h. Parameterized commands use byte 7 for value; byte 8 adjusts for checksum.

UDP transport: UDP port 57 accepts the identical RS232 hex command set. The "Enable ASCII command service (UDP port 57)" checkbox must be enabled on the Access Control page of the Remote Monitoring web interface.

Known bugs documented in source:

• Contrast changes not saved when hard power turned off
• Mute status query may not reflect actual state if mute was changed by serial commands
• Sharpness get returns value = setting + 4 (offset by 4)

SNMP monitoring: Read-only SNMP supported (community string "public", MIB: PLANARDISPLAY-MIB.txt, OID root 1.3.6.1.4.1.19125). SNMP objects are read-only with no traps.
