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 is a value that has its maximum at 255 and minimum at 0 if the data part is one byte. If the data part is two bytes the minimum strength is still at zero but the maximum strength is at 65535.

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

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.

Default coding: percentage.
Opt. codings: Scale 0-255 (1), Scale 0-65535 (2)

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

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.

Default coding: percentage. Optional codings: Scale 0-255 (1), Scale 0-65535 (2)

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

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.
