OptiLevel Supply – the transparency interface.
OptiLevel Supply is the interface between the higher-level system and the gauges, controlling their power supply voltage.
The OptiLevel Supply gives you the possibility of addressing up to eight gauges directly via a serial RS232 interface. A connection can then be made to fuel terminals, POS systems or modems, controllers, displays and so on. Up to four Supplies can be cascaded to control a maximum of 32 HLS gauges.
The OptiLevel Supply is responsible for the galvanic isolation of every individual gauge and therefore offers certain protection against explosions.
