SECTION 1 - INTRODUCTION
1.1 SCOPE OF MANUAL
This manual contains instructions for the installation, operation and maintenance of the BIT
4882, BIT 4882-F, and BIT 4886 Interface Cards manufactured by Kepco, Inc., Flushing, NY,
U.S.A. References to "Interface Card" refer to both models.
1.2 GENERAL DESCRIPTION
The Kepco BIT Card Series were designed as an accessory for the Kepco BOP series bipolar
power supplies. The BIT cards make it possible to control the BOP output by means of digital
input signals (see Figure 1-1). The BIT card acts as an interface between the digital data bus
and the BOP, accepting the digital input data and converting it to an analog signal, which in
turn, controls the BOP output. The BIT 4882, BIT4882-F and BIT 4886 provide full talk/listen
capability. They are fully compliant with SCPI and CIIL high level programming languages.
The BIT 488 design group consists of four models. Field installable interface cards carry the
prefix "BIT". BOP bipolar power supplies with an installed BIT interface card carry the suffixes
shown in Table 1-1.
Except for the installation procedures, the BIT 4882 and 4882-F cards are functionally identi-
cal. The BIT 4886 card is functionally identical to the BIT 4882 card are except that the BIT
4886 provides 16 bit resolution vs. 12 bit for the BIT 4882. The BIT 4882 and BIT 4886 cards
include a PC board mounted IEEE 488 connector used with the BOP Models indicated in
Table 1-2; the BIT 4882-F is an earlier version of the BIT 4882 which is compatible with most
BOP models, although it is intended for earlier BOP Models indicated in Table 1-2.
