5-15. Testing the RS-232 UUT Port via IEEE-488 Port
This procedure uses the GPIBTEST utility supplied with the recommended Ziatech
ZT-1444A IEEE-488 PC interface circuit card. Connect the UUT and PC as shown in
Figure 5-6. Note the use of a modem cable (NOT null modem) for UUT connection. (See
Appendix D 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 GPIBTEST utility.
1. Complete the "IEEE-488 Port Setup Procedure" earlier in this chapter to set up the
5820A for GPIB operation.
2. Complete "Testing the IEEE-488 Port" to prepare the 5820A Calibrator IEEE-488
port for testing. After Step 11, return to this procedure and continue to Step 3 below.
3. In the Main Control Window (below), select the Send to command from the Xfer
menu. This brings the focus back to the Parameter Input Window.
