CAUTION
*1: The 5 VDC power supply from the A172SENC must not be connected if a separate power
supply is used as the manual pulse generator power supply.
If a separate power supply is used as the manual pulse generator power supply, use a 5 V
stabilized power supply. Any other power supply may cause a failure.
