Reading a Command
Every command is a 5-byte hex string. Replace XX with the panel's ID:
01–FF targets one specific panel by ID.
00 broadcasts the command to all panels.
55 XX CMD DATA SUM
The final byte is a checksum. Send the bytes exactly as listed below.
Before You Start
These codes apply to the current-generation INF6513 panel. If a control or automation system was previously programmed for an earlier or now-superseded InFocus model, those older RS232 codes will not map across — the command set differs between generations. When integrating or re-integrating a INF6513, program the control system against the values in this article rather than reusing a previous panel's codes.
