INITIALIZATION OF THE BIT 4886 CARD
When a BIT 4886 Card is installed in a BOP it must be initialized prior to use. The initialization of
the BOP BIT card can be performed via either GPIB or RS 232 ports. The process can be
accomplished using the supplied computer program via the GPIB (see PAR. 4.2.1) or by send-
ing SCPI commands using either the RS 232 or GPIB protocol (see PAR. 4.2.2).
4.2.1
INITIALIZATION USING CVI DRIVER - GPIB PORT ONLY
The initialization procedure uses the “soft” front panel which is part of the CVI driver for the BIT
4886. The CVI Driver can be downloaded from the Kepco website at: www.kepcopower.com/
drivers.htm by choosing the appropriate model and CVI configuration. The CVI Driver can not
be used via the RS 232 Port.
1. Unzip the files and doubleclick on setup.exe to install the driver. The bit_mdac folder will be
added to the Start - Programs folder. Doubleclick bit_mdac.exe to run the program, and refer
to the visamdac.pdf in the bit_mdac folder for details about using the soft front panel.
2. Connect GPIB cable from the rear of the BOP with BIT 4886 Card installed to a Microsoft
Windows-based computer with National Instruments VISA software installed and verify that
BOP has standard PC-12 connector installed (Figure 2-2).
3. Install the VISA driver per the text file included with the driver. At the Start-up screen (Figure
4-2) set the correct GPIB Address and click
CONNECT
. Upon successful initialization the ini-
tialization window closes and the Power Supply Type field of the Start-up window (Figure 4-
2) shows BIT 4886. Click
Continue
.
4. Refer to Figure 4-3 and enter the following information:
•
