Description
Ring Indicator. When low, indicates to the modem that a
telephone ring signal has been received by the modem.
They are monitored during power-off for wakeup event
detection.
Note:
Data Carrier Detected. When low, indicates that the
data transfer device (e.g., modem) is ready to establish a
communications link.
Note:
Data Set Ready. When low, indicates that the data trans-
fer device (e.g., modem) is ready to establish a communi-
cations link.
Note:
Description
Acknowledge. Pulsed low by the printer to indicate that it
has received data from the Parallel Port.
Automatic Feed. When low, instructs the printer to auto-
matically feed a line after printing each line. This signal is
in TRI-STATE after a 0 is loaded into the corresponding
control register bit. An external 4.7 KΩ pull-up resistor
should be attached to this ball.
Data Strobe (EPP). Active low, used in EPP mode to
denote a data cycle. When the cycle is aborted, DSTRB#
becomes inactive (high).
Busy. Set high by the printer when it cannot accept
another character.
Wait. In EPP mode, the Parallel Port device uses this
active low signal to extend its access cycle.
Error. Set active low by the printer when it detects an
error.
Initialize. When low, initializes the printer. This signal is
in TRI-STATE after a 1 is loaded into the corresponding
control register bit. Use an external 4.7 KΩ pull-up resis-
tor.
If selected as RI2# function but not used, tie
RI2# high.
If selected as DCD2# function but not used, tie
DCD2# high.
If selected as DSR2# function but not used, tie
DSR2# low.
