Command clarification
Commands must each be finished with Cr Lf (0D 0A or Hex value &0D&0A)
■
“FC” (hex) delivers the current data set e.g. “23.351 25.462”
■
“S” delivers the serial number e.g. “79506000108”
■
“n” delivers the version, e.g. “V3.03”
■
“l” (lower-case l) Read – delivers a dump of all values from the memory in the format
e.g. “23.35 25.46 Cr Lf”
If data are read out from the instrument using the FC (hex) command, the
keyboard is locked. It can be enabled again using the 0 (hex) command.
The data are sent by the instrument in the following format.
Data type = String
The string length depends on whether it is a 1-channel or a 2-channel instrument. With a
2-channel instrument, the string can only be a max. 18 characters long.
