Setting Up RS-232 Remote Communications
All TDS3000, TDS3000B, and TDS3000C Series communication modules have
a 9-pin D-type shell RS-232 connector, as shown in Figure 1--4 on page 1--5.
The RS-232 interface provides a point-to-point connection between the
oscilloscope and equipment such as a computer or terminal. This section tells
how to connect and set up the oscilloscope for communication over the RS-232
interface.
The RS-232 standard defines two device types: Data Terminal Equipment (DTE)
and Data Communications Equipment (DCE). The TDS3000B and TDS3000C
series is a DTE device. In standard usage, DTE devices have a male connector,
and DCE devices have a female connector. You should use a straight-through
female-to-male cable of less than 50 feet for a local DTE-to-DCE connection.
Figure 1--14 shows the 9-pin connector with its pin number assignments.

Figure 1- 14: The RS-232 connector pin assignments
In terms of the connector and the way the oscilloscope uses the signal lines, the
oscilloscope behaves just like a PC/AT COM port. Table 1--4 lists cables you can
use to connect the oscilloscope to other devices.
