RS-232 CONNECTOR
The RS-232 port is configured according to the Electronic Industries
Association Standard RS-232-C published in August 1969. The Quadra can be
explicitly controlled with ASCII Command Set instructions sent via the RS-232
serial port from either a computer or an ASCII terminal. In Chapter 4, refer to
the “Command Set List
” section for details on all commands.

AND PINOUTS
Physically, the RS-232 port is a 9-pin D-Sub female connector. The pins for the
RS-232 connector are numbered from top to bottom, right to left. Looking at
the connector, pin #1 is located in the upper right corner, and pin #9 is in the
lower left corner.

NULL MODEM
You may need to connect Quadra’s serial port to a computer configured as Data
Communications Equipment (DCE). This is accomplished using a null modem.
The net effect of a null modem is to reverse the Transmitted Data and
Received Data connections within the cable. Also, the Request to Send (RTS)
and Clear to Send (CTS) connections are reversed. This may be done by using
a special “null modem” cable, or by inserting a small “null modem” box or
cable in series with a regular “straight through” cable.
