Overview

The D to A Converter card has 32 channels of 12-bit D to A output plus 32 addressable discrete lines. The Discrete outputs can be addressed as one 32 bit-word or two 16-bit words and have TTL output levels and drive capability. The Digital-to-Analog Converter card features 32 digital-to-analog outputs and 32 digital discrete outputs. The twelve-bit DACs provide 10 mAmps of drive current for a variety of voltage ranges. The voltage ranges are jumper selectable from: 0 to +5V, 0 to 10V, -5V to +5V and -10V to +10V. The discrete outputs can be addressed in several modes: as two 16-bit registers, as four 8-bit registers, or as thirty-two 1-bit registers. The discrete outputs are TTL compatible. The card receives data from either the Distribution & Host Interface or the Programmable Data Stream Processor via the A Bus.
