Figure 2-l shows typical IEEE-488 bus connections be­tween the computer, the Model 590 C-V Analyzer, and
the optional Model 230-l Voltage Source. Bus connec­tions to the hot chuck and switching matrix interface are
similar.
2.2.3 Default Primary Address Settings
The default primary address of each device associated with the Model 5958 is as follows:
. Model 590 C-V Analyzer: 15 . Temptronic 0315B Thermochuck: 9 . Optional Model 230-I Voltage Source: 13
You can select other addresses for the Models 590 and
230-I during installation. The thermochuck primary ad-
dress is defined in the hot chuck control file (see Section
6).
If a switching mainframe is used, the primary address must be that same as specified in the user-defined switch
control file (see Section 6). Also, any other devices con-
nected to the same IEEE-488 bus must not use any of the primary addresses listed above. Each device on the bus must have a unique primary address.

2.3 SOFTWARE INSTALLATION
SECTION 2
Getting Started
Place the installation disk in drive A: or B:, then type:
1.
2.3.1 Software Backup
Before installing the software on your hard disk, it is strongly recommended that you make backup copies of each of the disks supplied with the Model 5958. Use the DOS DISKCOPY command to make copies. For two­floppy disk systems, the general command syntax is:
DISKCOPY A: B: <Enter>
Here, the source disk is assumed to be in drive A, and the target (copy) disk is in drive B. (Note that DISK COPY can
be used only for the same type of drives; use COPY *.’ for dissimilar drives.)
Similarly, the command for single-floppy drive systems is:
DISKCOPY A: A: <Enter>
After copying all supplied disks, put the original disks away for safekeeping.
2.3.2 Installation Procedure
Follow the appropriate procedure below to install the Model 5958 software on your hard disk. The following paragraphs discuss using INSTALL.EXE to install the software.
NOTE INSTALL.EXE can also be used to reconfigure the software after installation. Select the reconfigure option to change an existing soft­ware configuration. (You can also run EQUIP.EXE after installation to select graph­ics and printer/plotter configurations.) You should have at least 5MB of free disk space prior to installing the Model 5958. (You can save some disk space by choosing not to in­stall source files during installation if they are not needed.)
A: <Enter> or B: <Enter>

2.3.3 IEEE-488 Driver Software Installation
The driver software for the IEEE488 interface card should be installed per manufacturer’s recommenda-
tions. Refer to the IEEE-488 driver software documenta-
tion for complete details.
2.3.4 CONFIG.SYS Modification
For most computer configurations, you should assign at
least 20 buffers and files in CONFIG.SYS. Use a text edi-
tor to modify or add the following lines:
FILES = 20 BUFFERS = 20
Serial Printer and Plotter Support
Model 5958 will drive printers or plotters connected to either the serial or paiallel port of your computer. If you are using the serial port, you must initialize the port by selecting the proper parameters for your particular serial connection during installation or reconfiguration. For Hewlett-Packard serial plotters, select eight data bits and one stop bit serial parameters.
The graphics routines use polling to send characters to
the serial port. Polling means that a character is sent, and
a check is made to see if the device is busy. If so, the mu-
tine waits until the device is ready to accept another char­acter. However, if the serial port device sends back any character other than busy, the transmission sequence will be interrupted. For that reason, be sure to set your printer
or plotter to its least intelligent mode (turn off handshak-
ing and status reports). Also, be sue to use the proper se-
rial cable, as the software requires that all serial signal
lines be present.

Laser Printer support
Model 5958 supports a Hewlett-Packard LaserJet+ or compatible printer with full-page 300dpi resolution. However, the printer must be equipped with at least
1.5MB of memory to support this resolution. In addition, some computer configurations may not have enough memory to support the required large bit map. In those cases, an “m” (300dpi, l/2 page) or “I” (150dpi, full page) plot can be performed.
GPIB (IEEE-488 Bus Plotter Support)
A GPIB HP-GL plotter can be used with the Model 5958
by selecting the “output to Driver 488 plotter” option on
the configuration menu. The plotter must be set for the addressable mode using a primary address of 5.
Note that a GPIB printer cannot be used.
2.3.6 Memory and Hard Disk Considerations
Your computer should have at least 400KB free base memory before running the software. Also, you should have at least 5MB of free hard disk space prior to installa­tmn.
it is recommended that the entire probe station be mounted in a suitable metal enclosure which is electri­cally connected to C-V Analyzer OUTPUT and INPUT LO. (Mounting chassis-mount BNC connectors on the en­closure chassis will electrically connect the enclosure to LO.)
WARNING Connect the shielded enclosure to safety earth ground using MSAWG or larger wire
before use.
NOTE Connections for the hot chuck, which is re­wired for BTS measurements. are not shown h Figure 2-2. Refer to the instruction manual for the hot chuck equipment for operating de­tails pertaining to that equipment. Note, how­ever, that some hot chuck.? connect chassis ground to the chuck. In that case, setup the Model 590 for floating operation (set rear panel ANALOG COMMON GROUNDING switch to the ungrounded position.)
When making C-V analyzer connections, keep the fol­lowing points in mind:
