Communication via Interface Commands

Interface commands are used to communicate directly with the pyrometer via the serial interface. Commands
can be used to write an own access control or can be entered in the terminal field of the software SensorTools
(see 7.6 Communication / Options) or entered via a terminal software.
▪ Data is exchanged in ASCII format with the following transmission parameters:
8 bit, 1 stop bit, even parity (8,1,e)
▪ Command sequence to write parameters:
2-digit device address → command → parameter → <CR> (Carriage Return)
▪ Command sequence to read out the current set parameters:
2-digit device address → command → <CR> (Carriage Return)
INFO
▪ Device address (also see in 6.2.12): In factory setting the device address is 00 but can be changed directly
at the pyrometer (under INTERFACE> → ADD).
In the Terminal field
▪ Parameters are encoded in hexadecimal unless specified otherwise.
▪ When writing with valid parameters, the response will be ok + <CR>
▪ When writing with invalid parameters, the response will be no + <CR>
▪ Deviating reading commands are in parentheses at the respective commands.
Example:
Input in terminal programs with device address 00:
0ar1<CR> sets the 2
00ar<CR> reads out how the analog output is set
Input in the Terminal field
ar1<CR> sets the 2
ar<CR> reads out how the analog output is set
