11.2 SSI protocol (data format)
Data formats
Gry24E and Bin24E: 24 data bit gray code/binary code +1 error bit binary
MSB LSB
Bit24 Bit23 Bit22 Bit21 ... Bit3 Bit2 Bit1 Bit0
D24 D23 D22 D21 ... D3 D2 D1 E
Gry24 and Bin24: 24 data bit gray code/binary code
MSB LSB
Bit23 Bit22 Bit21 Bit20 ... Bit2 Bit1 Bit0
D24 D23 D22 D21 ... D3 D2 D1
Gry25 and Bin25: 25 data bit gray code/binary code
MSB LSB
Bit24 Bit23 Bit22 Bit21 ... Bit3 Bit2 Bit1 Bit0
D25 D24 D23 D22 ... D4 D3 D2 D1
G24+8 and B24+8: 24 data bit gray code/binary code +8 status bit
MSB LSB
Bit31 Bit30 Bit29 Bit28 … Bit11 Bit10 Bit9 Bit8 Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0
D24 D23 D22 D21 … D4 D3 D2 D1 S8 S7 S6 S5 S4 S3 S2 S1
Function of status bits S1 ... S8:
S1: MF1 active
S2: MF2 active
S3: Measurement laser active
S4: Heater active
S5: Temperature, received signal level, plausibility warning (logical OR link)
S6: Measurement laser warning
S7: Temperature, received signal level, plausibility error (logical OR link)
S8: Measurement laser error
G25DME: 24 data bit +1 error bit, completely in 25 bit gray code
MSB LSB
Bit24 Bit23 Bit22 Bit21 ... Bit3 Bit2 Bit1 Bit0
This data format is based on the Bin24E format, however with a downstream gray coding over the entire 25 bit in-
cluding error bit. It is therefore compatible to the Gray25 format of the earlier DME3000, DME4000 and DME5000
device families.
