What are absolute maximum ratings and electrical specifications of the External I/O ? [External_IO]
(2006/03/16)

Answer... Refer to the following tables.
 
  1. KX-HCM230 and KX-HCM270
     
    Absolute maximum ratings of External I/O
    pin no item absolute maximum ratings notes
    no2 Output current 100mA --
    no3 Input voltage max Vcc +0.5V Vcc is voltage of power output (#2 pin)
    min VGND -0.5V VGND is voltage of GND (#1 pin)
    no4 Input voltage Vcc+0.5V Vcc is voltage of power output (#2 pin)
    Output current 100mA --

    Electrical specifications of External I/O
    pin no item conditions min ave max
    no2 DC power source voltage AC100V ± 10%,during communications
    PAN/TILT ON/OFF
    12V 14V 16V
    no3 low level input voltage -- -- -- 0.3V
    high level input voltage -- 2.8V -- --
    open circuit voltage input- Open -- 2.6V --
    low level input current input voltage-0V -- -- 1.8mA
    high level input current *1 input voltage-5V -- 0.6mA --
    input voltage-3.3V -- 0.15mA --
    pull-up register value -- -- 4.7KΩ --
    no4 high level output leakage current VOH=Vcc -- -- 0.5μA
    output saturation voltage 4 pin sink current-45mA -- -- 0.25V
    *1: When input signal from external sensor is logic level
     
  2. KX-HCM10 and KX-HCM8
