Setting Up and Testing the RS-232 Interface
You may need to set up and test the module RS-232 interface.
RS-232 is an 8-bit serial communications standa rd that lets the
oscilloscope communicate with an external RS-232 device such as a
computer, terminal, or printer. The sta ndard defines two device
types: Data Terminal Equipment (DTE ) and Data Communications
Equipment (DCE). The oscilloscope is a DTE device.
RS-232 Conventions on page 141 describes RS-232 conventions.
RS-232 Connector Pinout Diagram on page 142 shows a diagram of
the 9-pin RS-232 connector with pin numbers and signal assign-
ments.
