To be able to run the 394 software with the 384B, you must have firmware version F0:C1. The firmware version appears on the front panel read-out when the instrument is turned on. If you have F0:C1, install the 394 software on your computer, and perform the following:

Connect the ribbon cable (C0191) to the RS-232 port on the 384B and to your computer COM port on the PC using a 25-ti-9 pin adapter. The best port to put the analyzer on is COM 1.

Set the flow control for COM 1 to Hardware (as opposed to Xon/Xoff), and the Baud rate to 9600. For Win95, these changes are made within the Device Manager on Ports.

Changing 384B to 9600 baud rate (refer to 384B manual on page V-52):

1. Remove 4 screws from the top cover of the 384B. Loosen the 6 screws around the front extrusions. Remove top cover.
2. Look at the left rear corner of the instrument. On one of the two boards you will find a switch pack with 4 switches.
3. Change all of the switch positions (S1A=L, S1B=L, S2A=L, and S2B=H). This changes the Baud rate of the 384B to 9600 from 2400.

This should be all that is necessary to get the system communicating with the software.
