Connecting connector Configuration of the connector for power and interface which is packed in this box is as follows. Make sure to confirm the following configuration before connecting the connector. 5. 1 Function of each connector pins PIN NO.

For LED ERROR , there is a resister of 330 Ohm on the circuit side to make current value 10 mA. Please use LED which its voltage is approx. LED over 10 mA may break a control board. Make sure to supply power to all pins of power supply for circuit and power supply for operation to keep required current capacity. Serial interface equips a driver and receiver of RS-232C, make sure to use it at RS-232C level. RESET terminal is pulled up by 3. 3K Ohm. Make sue to make this terminal NC, when this terminal is not used. Absolutely, do not carry use No. 19, No. 21 and No. 40 pins. Since they are used for printer main unit. In case they are used, they may cause abnormality or break control board. 6 Parallel Interface 6. 1 Specifications Data input method Control signals : 8 bit parallel signal (DATA0 - 7) : ACK, BUSY, STB, FAULT, PE, RESET 6. 2 Explanation of input / output signals DATA0-7 STB RESET ACK BUSY FAULT PE : 8 bit parallel signal (Positive logic) : Strobe signal to read 8 bit data (Positive signal) : Signal to reset control board : 8 bit data request signal. Pulse signal output at the end of the BUSY signal (Negative logic) : Signal to indicate BUSY state of the printer. Input new data for "LOW" (Positive logic) : Signal which is made "LOW" when printer is in alarm state. (Negative logic) : Signal which is output when paper runs out. (Positive logic) CITIZEN 25 6. 3 Electrical characteristics (1) Input Signal Level All the input signals are at TTL level. "HIGH" level : 0. 7Vcc MIN "LOW" level : 0. 3Vcc MAX (2) Output Signal Level All the input signals are at TTL level. "HIGH" level : Vcc ­ 0. 1V MIN "LOW" level : 0. 1V MAX (3) I/O Conditions Input signal of STB and RESET are pulled up by 3. 3K Ohm. Others are pulled up by 50K Ohm. <Printer side> <Host side> All the output signals are pulled up by 50K Ohm. CITIZEN 26 6. 4 Timing chart (1) Data Input and Printing Timing ACK is not outputted. TYP : 500 ms MIN (On supplying power) 6. 5 Data receiving control When BUSY signal is "LOW", data from the host can be received. When it being "HIGH", data can not be received. [. . . ] Therefore, it is possible to include ESC @ into the content of macro definition. l Normal printing operation is carried out even while in macro definition (38) Macro Execution (GS ^ n1 n2 n3) Code : [1D]h + [5E]h + n1 + n2 + n3 * {0 n1 FF} {0 n2 FF} {0 3 1} Data is described in Hex code. l "n1 - n3" indicate as follows: n1 : The number of times of macro execution n2 : Waiting time on macro execution Waiting time of n2 x 100 msec is given for every execution. n3 : Macro execution mode n3 0 1 Continuous execution Mode Continuous execution Execution by LF SW : The Macro is executed n1 times continuously at the time intervals specified by n2.
