Notes

• Protocol uses ASCII-encoded hex for data bytes. Value 1234h sent as '1''2''3''4' (31h 32h 33h 34h).
• BCC (Block Check Code) = XOR of all bytes from D1 to D16.
• Packet interval: wait 600msec between commands.
• Monitor ID range: 1-100; Group ID: A-I; Broadcast: * (2Ah).
• Temperature readout is 2's complement; divide by 2 for Celsius.
• TV tuner commands (*1) only on US tuner models.
• Local Dimming (E328 model not supported).
• DHCP default; IP settings via User's manual.
