Sharp LCLE835 Series Control Spec

Summary

Sharp LCLE835 Series commercial LCD display supporting both RS-232C and TCP/IP control interfaces. The protocol uses a binary-encoded ASCII command structure with header, message, check code, and delimiter. Power control, VCP-style parameter get/set, and CTL system commands are documented.

Notes

• Protocol uses ASCII-encoded binary payload within TCP/Serial frames
• Packet interval must exceed 600ms between commands
• Monitor disconnects TCP connection after 15 minutes of inactivity
• Check code (BCC) calculated as XOR from bytes D1 through D16
• Header structure: SOH(1) + Reserved(1) + Destination(1) + Source(1) + MessageType(1) + MessageLength(2)
• VCP and CTL command types share same transport framing but differ in message format
• Some commands (Power ON/OFF, Auto Setup, Factory Reset) return NULL message if received during execution due to processing time required
