Resumen del manual


7-2. Clearing the Input Buffer In case it is desired to delete the data in the input buffer, the power switch should be turned on while pressing the SEL switch. When deletion of the buffer is completed the buzzer will sound. Please be sure to continue pressing the SEL switch until that time. If the printer fails to work properly at the time the power switch is turned on, please delete the input buffer as described above before inputting new data. CITIZEN 18/48 iDP-3540/41 User’s Manual 8. Parallel Interface 8-1. Specifications a) Data Input system : 8 bit parallel (DATA 1~8) b) Control Signals : ACK, BUSY, STB, FAULT, PE, RESET c) Compatible Connector : Printer side : 57LE-40360 (AMPHENOL or equivalent) : Cable side : 57-30360 (AMPHENOL or equivalent) 8-2.

Description of Input / Output Signals 8-3-1. Input / Output Signals a) Input / Output Signals *DATA : 8 bit parallel signal. (Positive logic) *STB : A strobe signal for reading in 8 bit data. (Negative logic) *RESET : A signal which resets the entire printer. (Negative logic, 1 ms or more) b) Output Signals (From Printer) *ACK : This is a pulse signal for requesting 8 bit data, issued at the end of a BUSY signal. (Negative logic) *BUSY : This signal indicates that your printer is in a BUSY state. New data should be input when this signal is “LOU”. (Positive logic) *FAULT : When your printer is in an alarm state, this signal is “LOW”. At this time, all control circuits of your printer are interrupted. (Negative logic) Note: An alarm condition occurs when the timing of the print head movement sensor is abnormal. c) Power Source *”H” Level : H level out put for TTL level *GND : The common circuit ground. *FRAME GND : Connect the shield of interface cable to this. CITIZEN 20/48 iDP-3540/41 User’s Manual 8-3-2. Electrical Characteristics a) Input Signal Level All input signals are TTL level. “HIGH” level …. 2.0V Min. “LOW” Level …. 0.8V Max. b) Output Signal Level “HIGH” level …. 2.4V Min. “LOW” Level …. 0.4V Max. c) Input / Output Conditions All of the input signals are pulled up by 3.3K ohms. [Printer Side] [Host Side] 7406 or equivalent All of the output signals are pulled up by 3.3K ohms. 7406 or equivalent CITIZEN 21/48 iDP-3540/41 User’s Manual 8-3-3. Timing Chart a) Data Input and Print Timing 8-3-4. Data Receiving Control Your printer is able to receive data sent from the host side when the BUSY signal is LOW, but unable to receive when the BUSY signal is HIGH. 8-3-5. Buffering 1) N Type Your printer is provided with a two line input buffer. 2) B Type Your printer is provided with a 7K byte input buffer. This makes possible a large amount of data buffering. And therefore, the host side is free immediately after data transmission. CITIZEN 22/48 iDP-3540/41 User’s Manual 9. Serial Interface 9-1. Specifications a) Synchronism : Asynchronous b) Baud rate : RS-232C type : 110, 150, 300, 600, 1200, 2400, 4800, 9600BPS (Selected by user) Current Loop : 110, 150, 300, 600, 1200BPS Type (Selected by user) c) Composition of one word : Start bit : 1 bit Data bit : 7 or 8 bit (selected by user) Parity bit : Odd, even or no parity (Selected user) Stop bit : 1 bit or more d) Signal Polarity : RS-232C type : *Mark = Logic “1” (-3V to –12V) *Space = Logic “0” (+3V to +12V) Current Loop : *Mark = Logic “1” (Current ON) Type *Space = Logic “0” (Current OFF) TTL type : *”H” level = Logic “1” Ref. to 8-3-2 *”L” level = Logic “0” e) Received Data : RS-232C & Current Loop (RD signal) *Mark = 1 *Space = 0 f) Receiving Control (RD signal) RS-232C : *Mark: Data Transfer not possible *Space: Data Transfer possible Current Loop : *Mark: (Current ON): Data Transfer possible *Space (Current OFF): Data Transfer not possible g) Transmission Control (TD signal) DC1 code (11H) “X” ON: Data Receiving possible DC3 code (13H) “X” OFF: Data Receiving not possible However, this is valid only for type B input buffer (7K).
