TMA VXI -27 101602
3.1.2.3 +5V OUTPUT
The +5V output is an auxiliary +5V source supplied through a 390 ohm resistor which can be
used to power user-supplied external TTL circuits.
3.2 REMOTE OPERATION
The TMA VXI-27 Power Module Controller is programmed over the VXIbus using either SCPI
(Standard Commands for Programmable Instruments) or CIIL (Control Interface Intermediate
Language) commands. SCPI and CIIL provide a common language used in an automatic test
system.
VXI plug&play drivers included with the TMA VXI-27 greatly simplify programming of power sup-
plies connected to the controller via the IEEE 1118 serial bus (see PAR. 3.3). For detailed pro-
gramming information, refer to PAR. 3.4 for VXIbus implementation, PAR. 3.5 for an explanation
of SCPI programming, and PAR. 3.6 for CIIL programming.
3.3 VXI plug&play OPERATION
The TMA VXI-27 Controller includes two disks used to install VXI plug&play drivers. Once these
drivers are installed, any of the power supplies connected to the TMA VXI-27 may be pro-
grammed directly; knowledge of the programming languages (SCPI and CIIL) and correspond-
ing syntax is not required if the plug&play drivers are used.
3.3.1 BACKGROUND
The VXI plug&play Systems Alliance was formed in September, 1993 with the objective of
increasing ease of use for end users of VXI technoloogy. The Alliance endorsed and imple-
mented additional common standards and practices in both hardware and software which
exceeded the scope of the VXI Specifications. These standards are used to define system
“frameworks” which give end users true “plug and play” interoperability at both the hardware and
software levels. Of the three currently defined frameworks, DOS, WIN and GWIN, the TMA VXI-
27 supports the GWIN (Graphical Windows) framework: an MS-DOS framework with key ele-
ments consisting of MS-Windows Soft Front Panel and LabView Drivers and documentation.
3.3.2 DRIVER INSTALLATION
The VXI plug&play install program uses the following structure: Drive C: is the default drive on
MS-DOS based computers (this may be changed during installation). The root directory for all
VXI plug&play drivers is VXIPNP. Each framework (DOS, WIN, and GWIN) is assigned a sepa-
rate subdirectory and each instrument is assigned a subdirectory of the applicable framework;
Figure 3-1 illlustrates the directory structure for the TMA VXI-27 plug&play drivers.
• kptmavxi.exe — MS-Windows standalone executable file for TMA VXI-27 soft panel.
• kptmavxi.llb — LabView driver for soft panel.
• kptmavxi.hlp — MS-Windows help file (the MS Windows help files are also found in
Appendix A).
• kptmavxi.kb — Knowledge base file which describes the TMA VXI-27.
To install the plug&play drivers, install floppy disk No. 1 in the appropropriate drive and run
SETUP.EXE, then follow directions as they appear on the screen.
