VSNC-500 General Dynamics VME Module

The General Dynamics / Veridian / Veda Systems IMUX Multiplexer platform supports any mix of data inputs. Up to sixty channels of analog, serial, parallel or message data may be input and multiplexed to an aggregate rate of 512 Mbps. IMUX data reproduction accuracy is extremely high, with selectable timing resolution better than one microsecond. IMUX provides the capability to output simultaneously all or selected channels to one or multiple recording devices through standard computer buses (SCSI) as well as other standard parallel interfaces such as DCRsi and VLDS.

IMUX provides high-fidelity reconstruction for individual channel timing and signal characteristics if required, but also allows immediate access to data parameters without the need for traditional demultiplexing and data reconstruction. IMUX stores data in a flexible computer readable file format. The IMUX archive format was designed for ease of reading and processing by any computer system. It is fully documented and is non-proprietary. This data can be read directly from tape and processed. Other formats, such as the newly defined standard based on CCSDS, are also supported by IMUX.

The IMUX hardware multiplexing function is based on our existing Series-30/OMEGA™ telemetry processing system architecture. Both products use the standard 6U VME module format. The same high-speed data bus used for multiplexing and transferring real-time data in our Series-30/OMEGA is also implemented in the IMUX architecture. This data bus is capable of transferring data at rates up to 128 MBytes per second, and is implemented on the user definable VME pins as described by VME bus standards.
