Moxa MPC-2150Z-T [57/65] Bru glass display control brightness button

MPC-2150 Hardware Display Control Interface Commands

B-3

BRU (Glass Display Control-Brightness Button)

This command is to set led brightness value of the touch keypad. The range starts 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 ? to query the current value of the led brightness value. LEN=one data byte.

Example:

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 on/off the buzzer.

If the data and data checksum of sending are incorrect, the data field of replying is current buzzer status.

LEN=one byte.

0x00 Turn the buzzer OFF

0xFF Turn the buzzer ON

Example:

Turn the buzzer ON.

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

ACK

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

DLN (Download ECDIS RGB Package)

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

command cannot be used if the MPC-2150 has not been calibrated. Every packet has a head (Byte 7 and Byte

8), Byte 7 is this packet number and Byte 8 is "-" with ASCII, and after the Bytes are data. If packet is full the

data is Byte 9 to Byte 38. LEN=one date byte.

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

Example:

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 - Data IDCHK

DL? (ECDIS RGB Package Query)

Use DL? to know how many available packets in each ECDIS table. This command cannot be used if the

MPC-2150 has not been calibrated. Total package num = Size of ECDIS RGB file/30 bytes per package.

Example:

Send DL? command to query total package num. of the first RGB file.

0x07 0xFF 0x44 0x4C 0x3F 0x00 0x2A

ACK 255 packages

0x06 0xFF 0x44 0x4C 0x3F 0x01 0x2A 0xFF 0x00
