Class=15 (0x0f) Data

CLASS1.DATA

Description

Representation for different general data types. Byte 0 is the data coding byte described here. Unit may not have meaning for some of the types and should be set to zero in that case.

Type = 0 (0x00) Undefined

General event.

Type = 1 (0x01) I/O – value

General I/O value. First data byte defines format.

Data byte Description
0 Data coding.
1-7 Data with format defined by byte 0.

Type = 2 (0x02) A/D value

General A/D value. First data byte defines format.

Data byte Description
0 Data coding.
1-7 Data with format defined by byte 0.

Type = 3 (0x03) D/A value

General D/A value. First data byte defines format.

Data byte Description
0 Data coding.
1-7 Data with format defined by byte 0.

Type = 4 (0x04) Relative strength

Relative strength.

Data byte Description
0 Data coding.
1-7 Data with format defined by byte 0.

Coding of units (Level I) | Code | Description | | ---- | ----------- | | 0 | Byte count = 2: Min = 0, Max = 255 \ Byte count = 3: Min = 0, Max = 65535 \ and so on... | | 1 | db (decibel) | | 2 | dbV (decibel volts) | | 3 | Undefined |

Units for Level II are the same as for Level I for the first four units.

Type = 5 (0x05) Signal Level

Signal Level is a relative strength value that (as default) has its maximum at 100 and minimum at 0 interpreted as a percentage. For a digital transmission Signal Level it can be used to give an indication of the analogue signal and CLASS1.DATA, Type = 6, Signal Quality can be used to give an indication of the quality of the digital part as BER (Bit Error Ratio) for example.

Data byte Description
0 Data coding.
1-7 Data with format defined by byte 0.

Coding of units (Level I) | Code | Description | | ---- | ----------- | | 0 | (0-100) percentage | | 1 | Byte count = 2: Min = 0, Max = 255 Byte count = 3: Min = 0, Max = 65535 and so on... |

Units for Level II are the same as for Level I for the first four units.

Type = 6 (0x06) Signal Quality

Signal Quality be used to give an indication of the quality of the digital part as BER (Bit Error Ratio) for example.

Data byte Description
0 Data coding.
1-7 Data with format defined by byte 0.

Coding of units (Level I)

Code Description
0 0-100, Percent
1 Byte count = 2: Min = 0, Max = 255 Byte count = 3: Min = 0, Max = 65535 and so on...
2 tbd

Units for Level II are the same as for Level I for the first four units.

Type = 7 (0x07) Count value

General counter value. First data byte defines format.

Data byte Description
0 Data coding.
1-7 Data with format defined by byte 0.
