Design and function	Optical interface
	Optical interface is integrated into the front panel of the calculator. It is designed for data reading
	via M-bus protocol and parameterization of the meter using SonoMeter 30 UserConfig software and
	optical head OG-1-USB.
	The optical interface is activated by pressing the control button and shuts automatically off 5 minutes
	after the last pressing button or after completing data transmission via interface.
	Wired M-Bus interface
	The energy meter has 1 slot for an additional communication module. The internal M-Bus module
	provides data reading possibility via M-Bus protocol:
	• M-Bus protocol according to EN13757-3 standard
	• 2-wire with polarity reversal protection
	• Electrical isolation
	• •Maximum voltage 50 V DC
	• Current drawn: one M-Bus load (1.5 mA)
