Terminating device messages:
The following end-of-text characters can be used for data receipt:
With IEC bus control: NL (hex: 0A) or NL & EOI or DAB & EOI;
With RS 232C control: NL or CR (hex: 0D) or ETB (hex: 17) or ETX (hex: 03).
The following end-of-message character is used when transmitting the response string:With IEC bus control: NL & EOI;
With RS 232C control: last received end-of-message character.
Abbreviating commands
: Abbreviated commands are identified with boldface letters. Letters not printed in boldface can be omitted. Example: “
OU
TPUT ?” = “OU?”
As a rule, letters can be entered in upper or lower case.
Stringing commands together
: Several commands is a single data string must be separated by semicolons (;). Example: “USET?; ISET?; OUTPUT?”
