Current consumption: LCD-background lighting Off: max. 350 mA (12 V DC) / 200 mA (24 V DC) LCD-background lighting 100%: max. 600 mA (12 V DC) / 300 mA (24 V DC)
Interface: External connections (optional / at Sub-D 9pol. connector X4 male)
Pin 8: EXTERNAL VOLTAGE FOR VARIABLE DIMMING: Analog input signal for variable controlling of the LCD-background and legends illumination. Input voltage free adjustable in the range of [1.5-33]V at edit menu (Display Control Unit Page 5). Look chapter edit menu. Default setting [10-28]V. (10V=Off, 28V=max. dimming) Impedance of input > 50 kΩ
Pin 6: NIGHT STATUS LINE: Low-active. At input voltage < 2.5V the dimming operates in night mode. Max. of brightness ca. 2% of day/default mode impedance of input > 50 kΩ  Only at SAR-DF 517 N with NVG front panel, otherwise do not use.
Pin 4: NVG STATUS LINE: Low-active. At input voltage < 2,5V the dimming operates in NVG mode. Max. of brightness ca. 2% of day/default mode Impedance of input > 50 kΩ Only at SAR-DF 517 N with NVG front panel, otherwise don’t connect.
Pin 7: AUDIO OUTPUT SIGNAL: AC coupled voltage source with very low inner resistance.  Max. output voltage app. 8Vss = 2,83VRMS at Volume Max.  Max. output power ca. 2W with 4Ω speaker.  If a headphone is connected [32…600]Ω / 100mW, we recommend using a resistor (18Ω / 0,25W) Between audio output and headphone to prevent damaging the headphone.
Serial interface RS232: (9600 baud, 8 databits, 1 stoppbit, no parity)

In relation to NE (New) parts, many OEMs change their prices and availability without any notice to dealers or the industry. Therefore, through the REQUEST or RFQ indication, we ask that customers contact us for the most accurate price and availability.

In relation to SV & OH parts, the used parts aftermarket in the aviation industry is not an infinite supply. It is a dynamic, constantly changing market that is significantly affected by and susceptible to highs and lows in supply and demand. Therefore, although we attempt to, at times, we are unable to predict the exact moment when an item may be available. Once again, through the REQUEST or RFQ indication on our website, we ask that customers contact us for the most current and accurate price and availability.
