Meaning of the Jumper-Group-ID bytes of answer:
Value (Hex)
Meaning
0x01
Jumper 1: position 1. if transfer param. =0: Jumper is in position 1
0x02
Jumper 1: position 2. if transfer param. =0: Jumper is in position 2
0x03
Channel 1
0xFF
Error
Possible error codes: 0xA0,0x59,0x91
Get Sensor Capacity
Command number: 164
Number of parameters: 0
Bytes sent by the GSV: 4
With Get Sensor Capacity the previously saved physical characteristic value of the
connected sensor can be read. The return parameter is encoded as floating point number
to basic 10, whereby the first byte indicates ex1 and the bytes 2 to 4 the mantissa
in High-endian order. The returned mantissa is the 1000000 time mantissa In point
presentation. Example:
The return is 0x04, 0x26
.25.A0
The decimal exponent is then 0x04 -1 = 3.
Mantissa must be divided by 10^6, in this example: 2 500 000 / 10^6 = 2,5
The characteristic value is then: 2,5 * 10^3 = 2500.
possible error code:
0xA0,0x91
Set Sensor Capacity
Command number: 165
Number of parameters: 4
Bytes sent by the GSV: 0
With Set Sensor Capacity the physical value of the connected sensor can be saved. The
transfer parameter is thereby as floating point number to basic 10 coded, whereby the first
byte indicates ex1 and the bytes 2 to 4 the mantissa in High-endian order. The
transferred mantissa is the 1000000 time mantissa in point presentation. Example:
Shall the characteristic value be 150, this means 1,5 * 10^2 (1,5E2)
The exponent byte is then 0x03 (2 +1).
The mantissa must be multiplied by 10^6, in this example: 1,5 * 10^6 = 1.500.000
value range uncoded: 0,01 bis 9.999.999
value range exponent byte: 0x00 bis 0x07
value range mantissa: 0x0186A0 bis 0x98967F
possible error code:
0xA0,0x54,0x55
