Overview

The Model 513V Parallel Device Interface Card is a VME-compatible 6U card that provides a programmable interface between external, third party decommutation equipment and the VME-based telemetry processing cardset built by Acroamatics.

Features

DATA TRANSFER

The 513V contains a setup channel to transfer information to external units and verify the data transfer from units that provide a setup verification capability.


 

16 BIT BUS

 Information transfer is program-contr olled via the VMEbus to or from the external 16-bit-wide, bi-directional, parallel I/O channel.


 

DUAL 32 BIT PARALLEL INPUT CHANNELS

The PORT car d provides two 32-bit-wide parallel input channels (Ports 1 & 2). Each of these ports accepts decommutated telemetry data and control signals, then formats the data for input to the Acroamatics 504V Distribution & Host Inter face car d. Each of the two input ports receives a data word that is a maximum length of 16 bits, and is accompanied by ID, Status, and Handshake control signals. The car d refor mats an input message to produce a 32 bit data word and a 32 bit tag word, that are then transferred to the distribution (DIST) card via the distribution input bus. The input data forms the 16 LSBs of a 32 bit word, with the 16 MSBs set to the value of the MSB (sign bit) of the input data word. The data word is preceded by a 32 bit tag word containing a 17 bit ID tag, three status flags, and a 12 bit fine time field. The construction of the ID word depends upon the availability of ID and status information from the input device.


 

FINE TIME

The fine time field is inserted into the tag word by the 503V TIME card when this word is being transferred to the 504V card. The 504V card uses the data and ID tags to select a 505V Programmable Data Stream Processor card. It also specifies the algorithms that are required to process and distribute the data to the desired output resource.

Technical Specs

INPUT PORTS (typical for both)

All 34 signals are single-ended TTL levels (.5 to 4.5 Volts)

16 Data Inputs

Line 0 is LSB - Line 15 is MSB (SIGN)

16 ID Inputs

The 12 LSBs are always ID (although not all lines may be active) - the 4 MSBs may be ID tag or special function, depending upon the signals available from the input channel. Seventeenth bit (MSB) added from Setup Channel Control Register.

1 Data Strobe

Generated by the external channel to indicate that the data & ID lines are stable

1 Channel Ready

Generated by the port card to indicate that the input channel is ready. Ready negates as handshake with data strobe.

OUTPUT PORT

All 18 signals are single-ended TTL levels (.5 to 4.5 Volts)

16 Data

Bi-directional lines, 8 LSBs are Data, 8 MSBs are Unit Address & Function

1 Data Strobe

A signal generated by the setup channel to indicate that the output word is stable. Also used as a Data Acknowledge handshake for receiving setup verification.

1 Data Acknowledge

A signal generated by the device being setup to acknowledge the data transfer. Also used as a Data Strobe function when verification data is sent back to the setup channel (Setup Channel Data Strobe becomes Data Acknowledge.)
