Overview

 

The Model 514V QPOI card is a VME-compatible 6U card that provides up to four output channels from the Device Bus (A-Bus) to any of the following: an external host computer such as the Acroamatics Model 5110 System Control Unit (SCU), a DEC computer equipped with a DR11W or DRV11W interface, a Gould Instruments TA4000 series strip chart recorder equipped with a digital input interface, or a 32-bit parallel output interface to a digital processing unit such as the Acroamatics Model 2420 Digital to Analog Converter. QPOI input is over the Device Bus, which provides processed and formatted telemetry data that you can programmably direct to any of the eight output devices that use this bus. Data processing occurs in the 504VA DIST and 505V PDSP cards. The telemetry compiler provides the software path that allows you to select the programmable message processing and output distribution on the device bus for a specific application.

 

Features

 

DR11W & DRV11W INTERFACE
The 514V card can include circuitry supporting data transfers from the Acroamatics Telemetry Data Processor to a DEC computer equipped with a DR11W or DRV11W interface card. The device bus device number is switch-selectable to support multi-channel configurations. 16-bit output channels are not available with this option.


 

32 BIT PARALLEL OUTPUT

You can configure this channel to be compatible with the DAC Bus, which is the input to external DAC circuits housed in our Model 2420 series chassis, or as a general purpose output channel. The output provides 16 data and 16 address lines along with an output strobe. The Device Bus device number is switch selectable, but is set to Device 7 to simulate the DAC bus function. You can use other device settings for general purpose data interfacing. and select the output format as 32-bit data or 16-bit data with ID tags.


 

16 BIT OUTPUT CHANNELS

The 514V also provides three 16 bit host computer interface channels to output processed data from the device bus. Output channel A is equipped with a Request and a Grant signal so you can transfer data via an external DMA channel. Output channel B provides 16 data lines with control signals to transfer data to two separate input ports. You can program-select the data to go to Channel 1, 2, or Both. Both A & B have a switch-selectable device address and are configured to allow multi-channel data input structures. The DR11 interface is not available with this option.


 

STRIP CHART FORMATTING
Output channel C receives data from either the A-Bus or the VMEBus as 32 bit messages, then formats
the data for transfer to a TA4000 series thermal digital strip chart recorder as two 16 bit transfers.
This channel processes messages to Device 7.
