4.1.3 CN1 Connection Example
* For each interface connection, refer to each item.
Notes:
1) As resistance 330Ω is inserted in the circuit so that current value of ERROR LED and PEOUT
LED is 10 mA, use the LED with forward voltage of 2 V or so. Using LED exceeding 10 mA
may break the control board.
2) Power supply for circuit (Vdd and GND) will operate if it is applied to only one pin. However,
driving power supply (Vp and P-GND) shall be fed to all pins to retain current capacity.
3) Note that though a ceramic capacitor is provided in the circuit to prevent chattering, great
chattering may occur depending on the switch. In this case, the user is requested to take an
appropriate measure.
4) Do not conduct such operation that only paper feeding continues for more than 5 minutes.
Excessive single operation of paper feed motor may cause failure. * In case of printing
operation (12.5% coloring), continuous operation over 5 minutes causes no trouble.
5) The RESET terminal is pulled up with 3.3 kΩ at the circuit side. If it is not in use, it must be
set as Non Connect.
6) Serial interface is equipped with RS-232C driver and receiver. Be sure to use in RS-232C
level.
7) Unused pin shall be insulated so that cable end may not contact other terminal or part.
