||
| 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) | ||
| Dimming: | |||
| 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 only at SAR-DF 517 N with NVG frontpanel, otherwise don’t connect. |
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 | ||
| Pin 4 NVG Status Line only at SAR-DF 517 N with NVG frontpanel, otherwise don’t connect. |
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 | ||
| Audio/NF: | |||
| 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. |
