Device control instructions
Device control instructions are used to determine the communication sequence between the cutting machine and computer
through RS-232C interface and/or tell the cutting machine the current computer state. among them, some device control
instructions set the output specifications of mode 2 instructions.
Each device control instruction is organized with three letters: ESC (1Bh), “.” and one upper case letter. Device control
instructions are of two types: one with parameters and the other without parameters.
Parameters can be omitted. A semicolon “;” is used as a delimiter to separate parameters if they are input in succession. A
“;” without parameters means that parameters were omitted.
If parameters are omitted, the default value is set. For a device control instruction with parameters, a terminator needs to be
input in order to signify the end of instructions. A colon “:” is used as the terminator which cannot be omitted.
