The Lumistar LS-71P PCI D/A Converter (DAC) board provides high speed analog outputs of PCM decommutated data allowing real time data displays using strip chart recorders or similar devices. The LS-71-P board is perfect for use in conjunction with the Lumistar LS-50- P Multifunction PCM Decommutator boards.  This is because it it uses an over the top communication bus directly from the decom to the DAC.  As a result, this avoids glitches in the analog outputs caused by PCI bus activity. Direct “mailbox” type access is also provided to allow the user to send information through the PCI bus to the DACs. The DAC board design allows users to combine 2 LS-50-D Multifunction decom boards with a single DAC board.  As a result, data from either data stream can direct to any DAC channel.
