: This could be software related to computer-aided design (CAD) specifically for gas chromatography (GC) systems. GC is a method used in chemistry to separate and analyze compounds that can be vaporized.

: This could refer to any software used to control, analyze, or interface with gas chromatography systems.

: The software can often be used even if the elevator's SIM card has been removed, though this may require advanced knowledge of "telegrams" (system commands) to perform basic tasks.

The software is typically used in conjunction with a specialized hardware kit to establish a physical connection between a laptop and the elevator control panel. Commonly available as V3.1 and V3.10. Interface
