TK23 OPERATION MANUAL
24/81
NOTES:
(1)
If the host is not provided with all or any of the Centronics Signal lines listed above
(TK23 specific signals are not required), both-way communication can fails.
(2)
For interfacing, is recommended that signal lines use twisted pair cables with the
return sides connected to signal ground level.
(3)
Data transmissions shall not ignore the /ACK or BUSY signals. An attempt to
transmit data with either /ACK or BUSY signal ignored, can cause lost data. (Data
transmissions to the printer shall be made after verifying the /ACK signal or while
the BUSY signal is at the low level.)
(4)
Interface cables shall have been made with the minimum length required (Max. 2
meters recommended).
