• Bytes 23 and 24 (labeled FF FF in the table above) contain the Failure Condition (if any):
OK (No failure) 00 00
Lamp Failure 00 01
Fan Failure (Lamp Cooling) 00 02
Overtemperature (Lamp Cooling) 00 08
If the unit is in Standby State this command is not recognized as a valid one, therefore the response is 15.
Signal Status
When then unit is On, the returned packet (25 byte long) is described in the following table:
1E BE EF 10 11 00 .. .. 01 01 00 01 01 15 01 00 00 08 00 00 00 SS .. .. II
0 1 17 18 20 21 24
where bytes marked with .. are not relevant.
The response may be separated into 4 parts:
• 1 bytes (byte 0) that initiates the packet (1E)
• 17 bytes (bytes 1-17) that duplicate the sent command (apart from 2 of them — the CRC)
• 3 Error bytes (bytes 18-20) that signal errors in the processing of the command
• 4 Data bytes (bytes 21-24) that contain the requested data
If the 3 Error bytes (bytes 18-20) are 00 00 00 then requested data are valid.
The tables below explain the meaning of returned data.
• Byte 21 (labeled SS in the table above) contains current Input Status:
OK 00
No Signal 01
Signal Out of Range 02
• Byte 24 (labeled II in the table above) contains Current Input:
1 Video 00
2 S-Video 02
3 YPrPb 04
RGB 05
4 Graphics RGB 0C
Graphics YPrPb 0D
5 HDMI 1 12
6 HDMI 2 13
If the unit is in Standby State the unit does not respond to this command.
