internally.
CAUTION
1. Do not apply voltage outside the range of 0 to 5 V
to the remote control input pins. Also, do not
short the output pins or apply external voltage to
them. If you do, the instrument may malfunction.
2. Do not short the D/A output terminal or apply
external voltage to it. If you do, the instrument
may malfunction.
3. When connecting the D/A output to another
device, do not connect the wrong signal pin.
Doing so may damage this instrument or the
connected instrument.
4. Pin17: VCC output, 5V. It serves as the
unregulated max power source for the external
device/logic. The maximum current is 100mA.
5. Pin5: Flyback Diode. It connects to VCC or
External power source.
