CoreModule 740
Serial Ring Indicator 1 – Indicates external modem is detecting a ring condition.
Software initiates operation to answer and open communication channel.
Parallel Select In – This output signal is used to select the printer. I/O pin in
ECP/EPP mode.
Ground 1 (Serial)
Parallel Data 3 – This signal provides parallel data to the printer.
Not Connected
Ground 2 (Serial)
Serial Data Carrier Detect 2 – Indicates external serial device is detecting a
carrier signal (i.e., a communication channel is currently open). In direct connect
environments, this is driven by DTR2 as part of the DTR2/DSR2 handshake.
Parallel Data 4 – This signal provides parallel data to the printer.
Serial Data Set Ready 2 – Indicates external serial device is powered, initialized,
and ready. Used as hardware handshake with DTR2 for overall readiness.
Ground 3 (Serial)
Serial Receive Data 2 – Serial port 2 receive data in.
Parallel Data 5 – This signal provides parallel data to the printer.
Serial Request To Send 2 – Indicates port is ready to transmit data. Used as
hardware handshake with CTS2 for low level flow control.
Ground 4 (Serial)
Serial Transmit Data 2 – Serial port 2 transmit data out.
Parallel Port Data 6 – This signal provides parallel data to the printer.
Serial Clear To Send 2 – Indicates external serial device is ready to receive data.
Used as hardware handshake with RTS2 for low level flow control.
Ground 5 (Serial)
Serial Data Terminal Ready 2 – Indicates port is powered, initialized, and ready.
Used as hardware handshake with DSR2 for overall readiness to communicate.
Parallel Port Data 7 – This signal provides parallel data to the printer.
Serial Ring Indicator 2 – Indicates external serial device is detecting a ring
condition. Software initiates operation to answer and open communication
channel.
Ground 6 (Serial)
Ground 7 (Serial)
Parallel Acknowledge – This is a status output signal from the printer. A low
state indicates it has received the data and is ready to accept new data.
to pin-3 on DB9 connector on I/O Interface Board.
Ground 8 (Serial)
USB 1 Power Protection – Port is disabled if this input is low. Direct inputs are
provided for over current protection.
Parallel Printer Busy – This is a status output signal from the printer. A high
state indicates the printer is not ready to accept data.
+5 volts +/-5% (USB1 Power)
Ground 9 (Serial)
