1.Application
Image intensifier tube operating voltage:2.2V-3.4V
There are three specifications for the tube, and the hardware interface needs to be compatible and reserved:
A. Two contact type image intensifier tube(Can’t adjust brightness gain)
B. Three contact/three wires type image intensifier tube(Can be adjust brightness gain)
Compatible with 3 types of batteries
1 piece of AA battery (non-rechargeable versions )
1 piece of CR123 lithium battery (rechargeable and non-rechargeable versions, Batteries with different voltages)
Noted:The device needs to be compatible with two different battery voltage specifications for operation.
2.Interface and key definitions
1.Light Sensor Window: Detect ambient light intensity for AUTO IR and strong light protection
2.4-pin Aviation Connector: Connect external battery box, priority power supply
3.Manual Gain Button: Stepless rotation (gain adjust) + pressing (function control)。
4.4-gear Mode Switch: OFF (full power off, no battery loss)/ON/IR/AUTO
5.IR Illuminator Port: 850nm IR output, 20m effective distance
6.Software Upgrade Interface: Reserved for future function upgrade
7.Status Indicator Light: Blue (auto standby prompt)/Red (IR on)/Green (strong light protection prompt)/Yellow (low battery alert)

4.Power Consumption & Working Time
Normal Mode
AA(1.5V-2000mAh): Power Consumption 132mW, Working Time 20h
CR123(3V-1400mA): Power Consumption 126mW, Working Time 30h
Rechargeable CR123(3.6V-700mAh): Power Consumption 126mW, Working Time 18
IR Mode
AA(1.5V-2000mAh): Power Consumption 142.5mW, Working Time 19h
CR123(3V-1400mA): Power Consumption 135mW, Working Time 28h
Rechargeable CR123(3.6V-700mAh): Power Consumption 135mW, Working Time 16.5h
Special Note: AA battery cannot supply transient starting current when voltage ＜1.35V (failure to power on), but works normally during continuous operation until voltage ＜1.2V. When external battery box is connected, the host is powered by AA battery normally.
