This listing is for one Brand NEW in BOX Vintage WIN-3016D x United Electronic Industries Inc. Ultra High Speed Data Acquisition Board. Board part number is WIN-3016Dx Box part number is WIN-30DA. Data Board is brand new in unopened package. please view pictures for more details. Here is some info I found online for a WIN-30D model board.... The WIN-30D is an ultra high performance multifunction analog and digital input/output board designed for the PC-AT compatible computers. The WIN-30D offers full 1 MHz throughput utilizing a spectrum of advanced technology, including data packing and a choice of bursting DMA, 16-bit Rep String operations, or, for the ultimate in performance and efficiency, 32-bit Rep String operations. The board can sample 1 channel at 1 MHz, 2 channels at 500 kHz each, up to 16 channels at 62.5 kHz each. All configuration of input ranges, DMA and interrupt levels, etc. is done in software. Once installed, the PC never needs to be opened again. The WIN-30D provides 16 singleended analog inputs with selectable ranges, and high impedance inputs. Software selectable voltage ranges are 0 to 5 V or +_ Vdc. Each input is individually buffered, obliviating the requirement for low impedance voltage sources, and eliminating all possibility of charge pump-back problems. The WIN-30D also features a channel list in hardware, which specifies the sequence in which input channels should be scanned. This technique allows complete flexibility in sampling, as channels can be sampled in any sequence, and allows the card to maintain its full 1 MHz throughout regardless of the number of channels sampled. Block scan mode, or near-simultaneous mode is also available. In this mode a preset number scanned on each strobe. This allows al 16 channels to be sampled within 16 ?sec. The WIN-30D offers the user the option of data packing. This packs four 12-bit samples into three 16-bit words, meaning that for each four 12 bit input samples, the host PC has only to perform three 16-bit AT-bus transfers. This reduces the card’s maximum data rate from 1 MHz to only 750 kHz. Conventional data transfer techniques on PCs are normally limited to either polled I/O or DMA. The WIN-30D offers three additional high speed techniques, Dual DMA Channel, 16-Bit Rep String, and 32-Bit Rep String operations. Dual DMA channel operation utilizes burst DMA transfers, allowing data to be acquired into all available memory, included extended or XMS memory, by utilizing two DMA channels, alternately. In contrast to conventional DMA technology, the bust DMA mode transfers a block of 512 samples, with only a single acquire/release operation for each block. This allows a typical AT class computer to reach a transfer rate of over 900 kwords per second. When used in combination with the WIN-30D’s data packing, this allows a maximum possible transfer rate of over 1.2 million samples per second, comfortably above WIN-30D’s max. sampling rate. Repeat string operations utilize the REP INSW instruction of 286/386/486 microprocessors. The Rep String instruction performs a zero-overhead look which inputs data from the WIN-30D to main system memory. Because processor generated I/O cycles (typically 350 nsec vs 800 nsec), data transfer rates are faster than DMA transfers. When combined with data packing, data transfer rates between 1.6 and 2.5 million samples per second are available. On 386 or better computers. the WIN- 30D can take advantage of 32-bit Rep String instructions, improving transfer rates and efficiency by approx. 10% over the 16-bit rep string.
