With the extended interface, both the software and the hardware can

control the data flow between the HP
and the controller. This
allows you to have more control of data flow between devices. The
HP
uses the following connections on its RS-232C interface for
extended interface communication:
l
Pm 7 SGND (Signal Ground)
l
Pin 2 TD (Transmit Data from HP
l
Pin 3 RD (Receive Data into HP
The additional lines you use depends on your controller’s implementation
of the extended
interface.
l
Pin 4 RTS (Request To Send) is an output from the
HP
which can be used to control incoming data flow.
l
Pm 5 CTS (Clear To Send) is an input to the HP
which controls data flow from the HP
l
Pm 6 DSR (Data Set Ready) is an input to the HP
which controls data flow from the HP
within two bytes.
l
Pin 8 DCD (Data Carrier Detect) is an input to the
HP
which controls data flow from the HP
within two bytes.
l
Pin 20 DTR (Data Terminal Ready) is an output from the
HP
which is enabled as long as the HP
is
turned on.
The TD (Transmit Data) line from the HP
must connect to the
RD (Receive Data) line on the controller. Likewise, the RD
from the
HP
must connect to the TD line on the controller.
