Technical description

The following table lists the parameter IDs and values.

The parameter value is sent in the request and response messages in the format given in the table.

The parameters are read and configured using the GET PARAMETER and SET PARAMETER messages.

Table 1. Parameters
Data ID Read/Write Scope Description Format Value
0x10 R/W Port specific

Baud rate (bps).

Defines the serial port speed.

When writing to parameters, the parameter value is updated immediately, but the changes take effect after a restart. Communication works with old values until software is restarted.

Baud rate change requires restart for the changes to take effect.

u8

0 = 9600

1 = 19200

2 = 38400

3 = 57600

4 = 115200

0x11 R Port specific Send acknowledgment about CRC checksum error. u8

0 = No

1 = Yes

0x12 R Port specific

Latest error code.

Read-only, not stored to non-volatile memory.

u8

For possible values, see Error codes

0x13 R/W Device specific

Mobile sensor unit ID that is used in the header.

When writing to parameters, the parameter value is updated immediately, but the changes take effect after a restart. Communication works with old values until software is restarted.

u8

1 = Default

Values 0xFE and 0xFF are not allowed.

0x14 R/W Port specific

Receiver ID when automatic data sending is started.

ID value is used as receiver ID only when automatic data sending is enabled.

u8 0 = Default
0x20 R/W Port specific

Data sending interval from MD30 to system (SEND DATA).

Data interval in milliseconds (ms).

See Automatic data sending.

u16

Range 25 ... 5000

0 = Automatic sending off (default)

0x21 R/W Port specific

Continuous sending started automatically after start-up.

See Automatic data sending.

u8

0 = Not enabled (default)

1 = Enabled

0x30 R/W Port specific

Temperature unit.

Changing temperature unit updates temperature offset correction parameters 0x40 and 0x41.

u8

0 = °C (default)

1 = °F

0x31 R/W Port specific Layer thickness unit. u8

0 = mm (default)

1 = inch

0x40 R/W Device specific

Road surface temperature offset correction.

Set and read using temperature unit selected with parameter 0x30.

f32 0 = Default
0x41 R/W Device specific

Air temperature offset correction.

Set and read using unit selected with parameter 0x30.

f32 0 = Default
0x50 R/W Device specific

Reference setting value of laser 1.

Value change requires restart for the changes to take effect.

f32

1.0 = Default

Value must be greater than 0

0x51 R/W Device specific

Reference setting value of laser 2.

Value change requires restart for the changes to take effect.

f32

1.0 = Default

Value must be greater than 0

0x52 R/W Device specific

Reference setting value of laser 3.

Value change requires restart for the changes to take effect.

f32

1.0 = Default

Value must be greater than 0

0x53 R/W Device specific

Dry road coefficient of laser 1.

Value change requires restart for the changes to take effect.

f32

1.0 = Default

Value must be greater than 0

0x54 R/W Device specific

Dry road coefficient of laser 2.

Value change requires restart for the changes to take effect.

f32

1.0 = Default

Value must be greater than 0

0x55 R/W Device specific

Dry road coefficient of laser 3.

Value change requires restart for the changes to take effect.

f32

1.0 = Default

Value must be greater than 0

0x56 R Device specific

Error condition causing reference setting to be interrupted.

Read-only, not stored to non-volatile memory.

Error code is reset when reference setting is started.

u32

When the SET PARAMETER message updates reference related parameters 0x50 - 0x55, changes take effect after the unit is restarted.

Receiver ID 0xFF can be used in cases where the assigned mobile sensor ID is not known to the client. The assigned ID is in the response message.
