[. . . ] To ensure reliable operation of the product and to protect it from overheating, do not block or cover these openings. The openings should never be blocked by placing the product on a bed, sofa, rug of other similar surface. This product should never be placed near or over a radiator or heater. This product should not be placed in an built-in installation unless proper ventilation is provided. [. . . ] (Positive logic) : When your printer is in an alarm state, this signal is "LOW". (Negative logic) : When the paper is near its end, this signal is issued. (Positive logic) Note: An alarm condition occurs when the timing of the print head movement sensor is abnormal. c) Power Source *+5V DC : The same +5V output as that of the power source which actuates the control circuits. : Equivalent to "case ground". *GND *FRAME GND 22 CITIZEN CBM-810/720/730/750 User's Manual (2) Electrical Characteristics a) Input Signal Level All input signals are TTL level. c) Input/Output Conditions All of the input signals are pulled up by 1K ohms. All of the output signals are pulled up by 3. 3K ohms. 23 CITIZEN CBM-810/720/730/750 User's Manual (3) Timing Chart a) Data Input and Print Timing (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. (5) Buffering 1) N Type Your printer is provided with a two line input buffer. This makes possible a large amount of data buffering, and therefore, the host side is free immediately after data transmission. 2) 24 CITIZEN CBM-810/720/730/750 User's Manual 9. 9. 1 SERIAL INTERFACE Specifications : Asynchronous a) Synchronism b) Baud rate: RS-232C type Current Loop type : 110, 150, 300, 600, 1200, 2400, 4800, 9600BPS (Selected by user) : 110, 150, 300, 600, 1200BPS (Selected by user) c) Composition of one word: Start bit : 1bit Data bit : 7 or 8 bits (selected by user) Parity bit : Odd, even or no parity (Selected by user) Stop bit : 1bit or more d) Signal Polarity : RS-232C type : *Mark = Logic "1" (-3V to -12V) *Space = Logic "0" (+3V to +12V) : *Mark = Logic "1" (Current ON) *Space = Logic "0" (Current OFF) Current Loop type e) Received Data: RS-232C & Current Loop (RD signal) *Mark = 1 *Space = 0 f) Receiving Control (DTR 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). 25 CITIZEN CBM-810/720/730/750 User's Manual 9. 2 Connector Pin Assignment Signal Pin 1 7 3 20 2 11 12 13 18 23 14 16 22 Return Signal Pin Signal Name FG GND RD DTR TD PE FAULT DTR RD RESET Direction Host/ Printer Function Safety Ground Signal Ground Received Data Printer BUSY Signal Transmitted Date Paper End Signal Printer ALARM Signal Printer BUSY Signal Received Data Printer RESET Signal O O O O RS-232C O O O O O O O Current Loop TTL Notes: [1] [2] [3] [4] The signals for RS-232C use are based on EIA RS-232C level. The loop current for Current Loop signal use should be restricted within the range of 10 to 20mA. Please always maintain the "mark state", when received data are not being transferred. The assignment of RS-232C/Current loop/TTL can be performed with the preset jumper (Refer to 10.

[2] Parity error When parity check is designated, and if when checked an error is detected, the ALARM lamp goes on, the buzzer sounds and the related data is ignored. [3] Overrun error When an overrun error is detected, the ALARM lamp goes on, the buzzer sounds and the related data is ignored. 28 CITIZEN CBM-810/720/730/750 User's Manual [4] Other errors When trouble is detected in the printer mechanism, the ALARM lamp goes on, the buzzer is sounded, the FAULT signal is output, and the DTR signal becomes BUSY. After the cause of the trouble has been corrected, the ALARM lamp can be turned off by pressing the LINE switch or by making RESET = "0". (4) Data Receiving Control When the BUSY signal is LOW, your printer receives data from the host side, but when this signal is HIGH, it cannot receive data. (5) Buffering Data transfer to the input buffer is controlled by the DTR and TD signals. Please refer to 9. 3 b) for the DTR signal and 9. 3 f) for the TD signal. 29 CITIZEN CBM-810/720/730/750 User's Manual (6) Electrical Characteristics a) RS-232C Circuit Input (RD) MAX232 or equivalent Mark = (-8V): Stop bit Space = (-8V): Start bit Output (DTR, TD, FAULT) MAX232 or equivalent *DTR (­8V): (+8V): *FAULT (­8V): (+8V): BUSY READY Normal Abnormal *TD Mark = (­8V): 1 Space = (+8V): 1 30 CITIZEN CBM-810/720/730/750 User's Manual b) Current Loop Circuit Input (RD) Mark Space Output (DTR, TD) = Current ON = Current OFF *DTR *TD c) TTL Circuit Output (PE) Current ON : READY Current OFF : BUSY Mark = Current ON Space = Current OFF 7406 or equivalent *PE H: L: Paper empty Paper reaming RESET 7406 or equivalent LOW for RESET 31 CITIZEN CBM-810/720/730/750 User's Manual 10.
