LC-graphic display: 128x64 dots, supertwist /transflective, extended range of temperature, dark-blue display on yellow-green background, lit up. Free adjustable (exponentiell) dimming of brightness
Supply voltage range: 12 V - 35 V DC
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)
Pin 3: Txd: Serial output (ca. ±10V)
