5.3 Description of Input / Output Signals
(1) Input signal
All input signals utilize type 74HC of CMOS and can be used in TTL level as the input is pulled up with
3.3 kWresistance.
- DATA 8 bit parallel signal (positive logic)
- STB Strobe signal for reading out data (negative logic)
- RESET Signal for resetting the entire unit (negative logic 4ms or more)
(2) Output signal
TTL is utilized for all output signals. The output is pulled up with 3.3kWresistance.
- ACK Signal for requesting data. ACK is issued at the end of the BUSY signal (negative logic)
- BUSY Signal indicating the printer is busy. Input new data when the signal is in “LOW”
condition.(positive logic)
- SELECT Signal indicating the printer is set to a selected condition (on-line). “HIGH” state indicates
the printer is selected.
(3) Others
- GND The common circuit ground.
- FG Equivalent to “case ground”.

6.3 Description of Input / Output Signal
(1) I / O signals
1) RD
Serial input data signal. Dada is ignored when framing error, overrun error, or parity error has occurred.
2) DTR
Input command or data while this signal is in ready state. Data input while the signal is BUSY will cause an overrun
error to occur and the data will be ignored. Data can be provided to the input buffer even if the printer is printing.
Busy state may also occur when power is applied, or during test printing, on-line, or when the printer is reset.
