Possible Command To Send To The Command Register
If it is necessary to perform the same command twice in a row, send the command 0 between a command and
the other.
Internal Status
When it is not 0 there is an internal error, so data from SCT20-IP are not reliable.
When it is 0 data from SCT20-IP are reliable.
Write Enable
Write 0x0000 in Write Enable register if you want that no data are written to SCT20-IP.
Write 0xFFFF in Write Enable register if you want to enable that data are written to SCT20-IP.
Gross weight, Net weight:
The weight values are expressed as positive integer numbers, include decimal figures but without decimal point.
Read the “Status Register” to obtain informations about sign and possible errors on the weight.
Setpoints:
The Setpoints are weight values expressed as positive integer numbers, include decimal figures but without
decimal point.
• READING: send to the Command Register the reading command of the required setpoint (e.g. 90 for reading
setpoint 1) and read the content of the "Setpoint" register.
• WRITING: write the weight value to be set in the “Setpoint” and send to the Command Register, the writing
command of the required setpoint (e.g. 93 for writing setpoint 1).
Setpoints are stored to the RAM volatile memory and lost upon instrument power off. To save them
permanently in the EEPROM memory, so that they are maintained upon the instrument power on, it is
necessary to send the command 99 “Save data in EEPROM” of the Command Register.
