MD-224 Hardware Manual Display UART Commands

C-3

BRU (Glass Display Control-Brightness Button)

This command sets the LED brightness value of the touch keypad. The range is from 0x00 to 0xFF (0% - 100%).

The default brightness value of the touch keypad will be changed in the ratio of the panel backlight brightness.

You can send a ? to query the current LED brightness value. LEN=one data byte.

Examples:

Command to set 100% Brightness.

0x07 0xFF 0x42 0x52 0x55 0x01 0x0F 0xFF 0x00

BZZ (Buzzer Control)

The default value for the buzzer is OFF. Users can send this command to turn the buzzer on/off.

If the data and data checksum are incorrect, the reply data field is the current buzzer status. LEN=one byte.

0x00 Turn the buzzer OFF

0xFF Turn the buzzer ON

0x3F Query the current status

Examples:

Turn the buzzer ON.

0x07 0xFF 0x42 0x5A 0x5A 0x01 0x02 0xFF 0x00

ACK

0x06 0xFF 0x42 0x5A 0x5A 0x01 0x03 0xFF 0x00

Query the current status.

0x07 0xFF 0x42 0x5A 0x5A 0x01 0x02 0x3F 0xC0

ACK the current status of the buzzer is ON

0x06 0xFF 0x42 0x5A 0x5A 0x01 0x03 0xFF 0x00

DLN (Download ECDIS RGB Package)

Before sending this command, use DL? to determine how many available packets are in each ECDIS table. This

command cannot be used if the MD-224 has not been calibrated. Every packet has a head (Byte 7 and Byte 8);

Byte 7 is this packet number and Byte 8 is the ASCII code for “-”; the remaining bytes are the data. If the

packet is full the data is in Byte 9 to Byte 38. LEN=one data byte.

Data length is 32. The first byte is package num., the second byte is “-” and the other 30 bytes are data.

Examples:

Command to read package 0.

0x07 0xFF 0x44 0x4C 0x4E 0x01 0x1A 0x00 0xFF

ACK the package 0 of the first RGB file

0x06 0xFF 0x44 0x4C 0x4E 0x20 0xFC 0x00 0x2D Data IDCHK
