transmitted Data (tD or tX)
This is the pin on which the computer sends the
actual data signal representing the actual infor-
mation to be printed, i.e. a positive voltage (+3V
to +5V) to represent a logic “0”, and a negative
voltage (-3V to -5V) to represent a logic “”.
Ring indicator (Ri)
This line is used by the peripheral device to tell
the computer that a remote device wants to start
communicating. A modem would activate the
Ri
line to tell the computer that a remote modem
was calling, i.e. the phone is ringing. In the case
of a printer, this line is unused.
Data carrier Detect (DcD)
This line is used by a peripheral device to tell the
computer to expect to start receiving data at any
time. Since the printer would not be sending data
to the PC in this case this line is not needed.
Received Data (RD or RX)
This is the pin on which the computer receives
the incoming data signal, i.e. a positive voltage
(+3V to +5V) to represent a logic “0”, and a
negative voltage (-3V to -5V) to represent a
logic “”. Again, in this instance, since the printer
will not be sending the PC any data, this line is
not needed
.
