Function
Connected to the (+) side of
the open/close detection
switch on the cash drawer.
Pulled up through a 10 k
Ω
resistor on the printer side.
+24 VDC for drawer kick-out
is supplied.
Drawer kick-out drive signal
L2.
Connected to the (-) side
of the open/dose detection
switch on the cash drawer.
Connected to the signal
ground on the printer side.
This signal outputs the pulses specified by the
ESC
p command.
The SW (+) state is checked by the host computer using the ESC u
command.
Electrical characteristics:
(a) Signal output current:
Maximum -1 A (510 ms or less)
(b) Power supply output voltage:
24 VDC (typical)
(c) Power supply output current:
Maximum 1 A (510 ms or less)
(d) Output waveform:
Refer to Figure B-l
NOTES:
1. These are not output during printing.
2. Drawer kick-out drive signals L1 and L2 cannot be output at the same
time.
3. The resistance of the drawer kick-out solenoids should be 24
Ω
or
more. Otherwise, the overcurrent could damage the solenoids.
4. Be sure to use the power supply (pin 4) of the drawer kick-out
connector for the drawer kick-out solenoid power source.
3) Drawer open/close signal
SW (+) signal level:
“LOW = 0 to 0.5 V
“HIGH” = 3 to 5 V
NOTE:
Do not connect anything otherthan a solenoid to the drive signal terminal
of the drawer kick-out connector.
