5-15. Testing the RS-232 UUT Port via IEEE-488 Port
This procedure uses the Win32 Interactive Control utility supplied by National
Instruments with the recommended interface cards. Connect the UUT, Calibrator, and
PC as shown in Figure 5-6. Note the use of a modem cable (NOT null modem) for the
UUT connection. (See Appendix C for information about RS-232 cables and
connectors.)

Figure 5-6. Testing the RS-232 UUT Port via IEEE-488 Port
Complete the following procedure to test RS-232 UUT port operation via the IEEE-488
port using the Win32 Interactive Control utility.
1. Complete the “IEEE-488 Port Setup Procedure” earlier in this chapter to set up the
5520A for GPIB operation.
2. Complete “Testing the IEEE-488 Port” to prepare the Calibrator IEEE-488 port for
testing. Before the final step, return to this procedure and continue to Step 3 below.
3. Go to Start then to the Programs menu.
4. Select "NI-488.2M software for... (your operating system)".
5. From the NI488.2M software menu, select "Win32 interactive control".
6. A DOS window opens with a prompt as shown here:
