8.3 Description of Input/Output Signals
(1) Input/Output Signals
a) Input Signals (To Printer)
*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.
(Negativelog ic)
*BUSY : This sign al indicates that your printer is in a BUSY state. New data should be input
when this signal is "LOW". (Positive logic)
*FAULT : When your printer is in an alarms tate, this signal is "LOW". At this time, all control
circuits of your printer are interrupted. (Negative logic)
*PE : When the pape r is near its end, this signal is issued. (Positiv elogic)
Note: An alarmcondition 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.
This should be less than 30 mA.
*GND : The common circuit ground.
*FRAME GND : Equivalent to "caseground".

(4) Data ReceivingControl
Your printer is able to receive data sent fromthe ho st 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.
2) B Type
Your printer is provided with a 7K byte input buffer. This makes possible a large am ount of data buffering,
and therefore, the host side is free immediately after data transmission.

9.3 Description of Input/Output Signals
(1) Input/Output Signals
a) RD :
This is the serial signal for received data. When framing, overrun or parity errors occur, the data concerned are
ignored.
b) DTR :
Please write in data or commands when this signal is in a "ready " state. If written in when in a BUSY state, an
overrun erro r will occu r and the data will be igno red. Data can be written into the input buffer even du ring
printing. Further, a BUSY signal is gene rated when the power is turned on, while test printing, when
ONLINEE and during reset.
c) FAULT :
When there is a problem in the printer mechanism the FAULT signal will be issued, and all control circuits will
be interrupted. To RESET this signal, first correct the cause of trouble in the printer mechanism. Then, by
pressing the LINE switch or by inputting "0" (LOW LEVEL) at the RESET terminal, the FAULT can be
cleared.
Causes of the FAULT signal are lack of paper and errors in the printer mechanism. Printer errors include such
as, the print head stopping during print operation or failure of the print head to return to the home position.
d) RESET:
This signal resets the entire printer.
e) PE :
This signal is output whenthe paper roll is near the end.
f) TD (Valid only for type B):
When receiving data signals, and when the printer's input buff er has less than 1K bytes remaining open, the
DC3 code (13H) is issued, ind icating that receipt of data is not possible. When the data in the input buffer is
reducedto 2K bytes, the DC1 (11H) codeis issued,which indicates that data receipt is possible.
g) FG:
Fram e Ground
h) GND:
Common ground for all circuits.

(2) Data Composition
[1] Start bit
[2] Data bits (andparity bit)
[3] Stop bit (1 bit or more)
[1] Start bit
1/2 bit past the line dropping from MARK to SPACE, a status reading is taken again. If the reading is SPACE,
a start bit is recognized , but if it is MARK, it is not taken as a start bit. Th is is not regarded as an error, but the
search for the start bit is performed once again.
[2] Data bit andParity bit
Data bits and parity bits are the data of the bits in question, which are represented by the state at the times
sampling is performed. This is accomplished at time intervals equal to one bit in length, beginning from the
middle of the start bit. The order of the bits is, starting with the bit closest to the start bit, bit-0, bit-1 ....., pa rity
bit. (Note: data bits are based on "one point sa mpling".)
[3] Stop bit
The stop bit consists of one or more bits at "mark" level. When"space" level is detected for a stop bit, a framing
error occurs.
(3) Error Detection
Parity, framing and overrun errors can be detected by your printer. When an error is detected, the ALARM
lamp goes on, the buzzer is sounded, the related data is abandoned, and the printer shifts to the next incoming data.
The ALARM lamp can be turned off by pressing the LINE switc h.
[1] Framingerror
When "space" state is detected during stop bit sampling, the ALARM lamp goes on, the buzzer sounds, and the
related data is ignored.
[2] Parityerror
When parity check is designated, and if when checked an error is detected, the ALARM lamp goes on, the
buzzer sounds and the relateddata 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-710/720/730/750 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,
theALARMlampcanbeturnedoffbypressingtheLINEswitchorbymakingRESET="0".Whentheprinter
is put ONLINE, data receiving restarts.
(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.
