5 BOS/S DIGITAL CONTROLLER BOARD
5.1 INTRODUCTION TO THE BOS/S DIGITAL CONTROLLER BOARD
The following contains all instructions for operation of the BOS/S Digital Controller
Board. This board is a factory-installed option for remote computer control of the
BOS/S power supply, manufactured by Electronic Measurements.
5.2 GENERAL DESCRIPTION
The BOS/S Digital Controller Board provides a means to remotely computer control an
Electronic Measurements, Inc. BOS/S Power Supply. This board is factory installed
within the existing BOS/S enclosure. The controller is interfaced via the General
Purpose Interface Bus (GPIB) or the RS232C serial communications link. Either or
both of these interface methods are available and both can be used at the same time,
providing a great degree of user flexibility.
The controller allows remote duplication of all BOS/S front panel controls. Front panel
controls are remotely locked out by the user via the controller card.
