All signals are TTL compatible.
STB#
This active low pulse is used to strobe the printer data into the printer.
AFD#
This active low output causes the printer to automatically feed one line after each line is printed.
PD0...PD7
This bi-directional parallel data bus is used to transfer information between CPU and peripherals.
ERR#
This active low signal indicates an error situation at the printer.
INIT#
This active low signal is used to initiate the printer when low.
SLIN#
This active low signal selects the printer.
ACK#
This active low output from the printer indicates it has received the data and is ready to receive new data.
BUSY#
This signal indicates the printer is busy and not ready to receive new data.
PE
This signal indicates that the printer is out of paper.
SLCT
This active high output from the printer indicates that it has power on.
DTR2#
Active low data terminal ready output for the serial port. Handshake output signal notifies modem that the
UART is ready to establish data communication link.
RI2#
Active low input signal which notifies the UART that the telephone ring signal is detected by the modem.
SOUT2
Transmitter serial data output from serial port.
SIN2
Receiver serial data input.
CTS2#
Active low input handshake signal which notifies the UART that the modem is ready to receive data.
RTS2#
Active low output handshake signal notifies the modem that the UART is ready to transmit data.
DCD2#
Active low input handshake signal which notifies the UART that carrier signal is detected by the modem.
DSR2#
Active low input handshake signal which notifies the UART that the modem is ready to establish the com-
