Read Frequency
Command number: 22
Number of parameters: 0
Bytes sent by the GSV: 3
The 3 parameter bytes returned from the command ReadFrequency are coding the
measuring data rate.
With the GSV-21 the data range is not continuously settable (look at
Set Frequency
).
That's why the decoded data rate read with Read Frequency may vary a little bit from the
value setted before (e.g. with Set Frequency).
The decoding formula for the command 22 is:
Data rate = 5000000 / (16777216 – register value read)
Possible error codes 0xA0,0x91,(0x81)
Get norm
Command number: 26
Number of parameters: 0
Bytes sent by the GSV: 3
Get norm
determines the scaling factor register value, as described in
set norm
(without
the related decimal point setting).
Possible error codes 0xA0,0x91
Get unit
Command number: 27
Number of parameters: 0
Bytes sent by the GSV: 1
Get unit
determines the unit register, as described in
set unit
(look at the list of unit
codes).
Possible error codes 0xA0,0x91
Get dpoint
Command number: 28
Number of parameters: 0
Bytes sent by the GSV: 1
Get dpoint
determines the decimal point, as described in
set dpoint
.
Possible error codes 0xA0,0x91
Switch
Command number: 29
Number of parameters: 1
Bytes sent by the GSV: 0
Switch
switches the switch output corresponding to the parameter byte, which is either on
(1) or off (0). The state of the switch output only remains if the measured value is within
