The Specifications
of the Interface
Device control
Device control instructions are used to determine the communication sequence between the plotter and computer
through RS-232C interface and/or tell the plotter the current computer state. Among them, some device control
instructions set the output specifications of RD-GLI/II instructions.
Each device control instruction is organized with three letters: ESC (1Bh), “.” and one uppercase 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. Please refer to the following table for device control instructions. Depending on the instruction set that
has been selected, some device control instructions may be ignored.
