10.3 Input and Output Signals

10.3.1 Input and Output Signals

(1) RXD

This is a serial received data signal. When a framing error, overrun error, or parity error occurs, that
data is printed as "?".

(2) DTR

When this signal is Ready, write the data or a command. If written at the time of Busy, an overrun
error results, ignoring the previous data. The data can be written in the input buffer even during
printing. Busy is also issuedat the time of power-on, test print, on-line, and reset.

(3) TXD

As data is received, the remaining capacity of the printer’s input buffer decreases.
When it becomes less than 128(10) bytes, a DC3(13H)(Data reception disable signal) is output to the

iDP3420/3421/3423 User’s Manual

host computer. On the other hand, when the remaining capacity of the input buffer increases to
256(20) or more bytes, a DC1(11H)(Data reception enable signal) is output to the host computer.
XON (11H) is sent every 3 seconds in the Star mode.
When a command is received, that requests the printer state and printer status, 1-byte corresponding
data is output.

Note: Thevaluesin()areforwhenthe256bytesoftheinput buffer is selected by

DIP switches.

(4) DSR

When this signal is a space, the data is sent from the printer side. Note that if this sign al is a mark
when a request to send command is executed, the printer will wait until the signal becomes a space.

(5) FAULT

1CBM mode

Whenthis signal is Space,a mechanical error has occurred.

2Star mode

Whenthis signal is Mark, a mechanical error hasoccurred.

(6) RESET

A signal to reset the entireprinter. (Negative logic)

33 CITIZEN

iDP3420/3421/3423 User’s Manual

(7) RTS

This signal is turned to Space when the printer is turned on.

(8) RCH

When the printer is ready to receive, this signal is turned to Space. This signal line is the same as
DTR.

(9) mTXD

TXD signal for the diode gate.

(1) Start Bit

(3) StopBit (1 or More)

(1) Start bit

After a lapse of 1/2 bit from a mark-to-space fall edge, the state is read again, and if it is a space, it is
recognized as the start bit. If it is a mark, it is assumed neither the start bit nor an error, and it is
attemptedto detect the start bit again.

(2) Data bit + parity bit

The data bit and parity bit are sampled for 1 bit worth of time from the 1/2 start bit. The then state
is assumed the data for the corresponding bit. A sequence of the bits are named Bit 0, Bit 1, ...,
parity bit, starting from the one closest to the start bit.

(3) Stop bit

The stop bit is a mark level of 1 bit or more. If a space is detected in detecting the stop bit, a
framingerror results.

35 CITIZEN

10.3.3 Error Detection

A parity error, framing error, and overrun error are detected. When an error is detected, that data is
stored in the buffer as "?".

(1) Framing error

This error results when a space is detected in detecting the stop bit. That data is stored in the buffer
as "?".

(2) Parity error

If a parity check has been specified and an error is detected at the time of parity check, t hat data is
stored in the buffer as "?".

(3) Overrunerror

If an overrun error is detected, that data is stored in the buffer as "?".
