Command (CMD) bytes:
ASCII Byte0 Byte1 Byte2 Data Description
TMP 0x54 0x4D 0x50 0x52 Return current temperature
MAN 0x4D 0x41 0x4E - Return manufacture ID "NIN".
TYP 0x54 0x59 0x50 - Return monitor type as defined in the monitorinfo.txt file located at the
microSD-card. Syntax for setting TYP value in monitorinfo.txt:
MONITOR_TYPE={string up to 16 characters}
BRT 0x42 0x52 0x54 1 byte Set BL level.
SLI 0x53 0x4C 0x49 1 byte Set current input: 0x03 = DVI1, 0x0F = DP1, 0x04 = DVI2 and 0x10 =
DP2.
SWI 0x53 0x57 0x49 - Return sw version as defined in the monitorinfo.txt file located at the
microSD-card. Syntax for setting SW value in monitorinfo.txt:
SOFTWARE_ID={string up to 16 characters}
ETC 0x45 0x54 0x43 - Return system run time
SNB 0x53 0x4E 0x42 - Return Serial number
LFD 0x4C 0x46 0x44 - Command monitor to Load factory defaults
BZZ 0x42 0x5A 0x5A 1 byte Buzzer control (note that both 0xFF and 0x01 turn on buzzer, 0x00
turn off buzzer)
Furthermore, commands for simulating HMI keypresses are available:
Corresponding HMI key Command syntax (complete command)
Menu button (J25_HMI3) 07 FF 4D 43 43 01 25 F7 08
ECS button (J25_HMI2) 07 FF 4D 43 43 01 25 FB 04
+ button (J25_HMI0) 07 FF 4D 43 43 01 25 FC 03
- Button (J25_HMI1) 07 FF 4D 43 43 01 25 FD 02
Data length (LEN) byte:
Length of DAT in bytes (0-74 bytes)
Inverse Header Checksum (IHC) byte:
It is a simple 8 bit checksum of the header data (bytes 0 to 5) where a bit-wise inversion has been performed. The
checksum must be initialised to 0. The 8 bit sum (without carry) of bytes 0-6 must be 0xFF.
IHC = 0xFF – (ATT+ADD+CMD0+COM1+COM2+LEN), where only 8 bits are used.
If a message checksum fails the controller will reply with the attention byte 0x15 and no data bytes.
Data (DAT) bytes:
The data bytes will only be send if data length (LEN) is greater than 0.
The data bytes are designated DAT0, DAT1, DAT2, etc.
