- Serial interface connection example.
NOTE: Transmit data to the printer after turning on the power and initializing the
printer.
The TK41 receives data continuously, even while performing printing operation.
The TK41 serial input/output signals (RXD, /RTS and TXD) can be RS232C level or
TTL level (see
APPENDIX E- HOW TO ORDER
).
The TK41 receives and checks serial data according to the transmission baud rate
programmed.
If the input data is not printed correctly, the transmission conditions between the host
device and the TK41 do not probably match. If this happens, the character
“?”
is
continuously printed and user must adjust the transmission conditions so that they
match.
Serial data output (TXD): output pin, SUB-D9-3
•
Data is output according to the programmed transmission conditions.
Serial data input (RXD): input pin, SUB-D9-2
•
Data input port
•
Data is input from the host device according to the programmed transmission
conditions.
Serial busy (/RTS): output pin, SUB-D9-7
•
Indicates whether or not the printer is ready to receive data.
•
When the /RTS signal is “LOW”, data can be input.
NOTE:
For more information on serial data reception see point 3.5.8- SERIAL PORT
ERROR DETECTION FLOW CHART.
Connect the communications cable before turning ON the TK-41.
