7-3 Battery, RTC(Clock), Buzzer and Cash Drawer Circuits
7-3-4 Cash Drawer Driving Circuit
The circuit is used for opening cash drawer and driven by the Q5(MMBT222A),Q1(KSD288-Y). When its state is high
level signal, Q5(MMBT222A) or Q1 (KSD288-Y) drive the solenoid to open the cash drawer. As an optional item, we
provide sensor switch (we call it a compulsory switch) which checks the drawer whether it is opened or not. This sensor
switch turns on for the drawer open condition, and turns off for the other.
Caution:
Make sure that the Cash Drawer solenoid resistance is more than 20

7-3-5 VFD Display Block Circuits
This uses 10digit Fluorescent Display and uses UCN5812AF (is located on the Front VFD PCB) for the driver. CPU
sends Display data to the driver repeatedly having given time interval in series and then Fluorescent Display is operated.
