The RS-232 Connector
The RS-232 port on the GPIB-232CV is configured as a DTE (Data
Terminal Equipment) and uses a standard 25-pin shielded D-subminiature
female connector with screwlock assemblies. The RS-232 connector will
accept standard 25-pin D-subminiature male connectors. A diagram of the
serial connector and the signals supported is shown in Figure 1-4. For more
information on the RS-232 signals refer to Appendix B, Interfacing to a
Serial Device.
