The ECL / LVDS-E / RS422-E is a mezzanine board that pairs with an EDT main board (for PCI or PCI Express) for high-speed data transfer. This “E-series” board can be ordered ECL, LVDS or RS-422 inputs/outputs in groups of four, with an E1/T1 option.
Each channel inputs or outputs a signal on the edge of the associated clock, and the data is stored in or sent from host memory via DMA for a simple, flexible data transfer solution.
Also available is an earlier “non-E” LVDS/RS422 board (identifiable by the absence of a fan), which does not support ECL or E1/T1 and works only with a PCI SS or PCI GS main board. Applications designed for this “non-E” board require different configuration files and minor program changes to work with the “E” board, as detailed in the manual.
For details on system requirements and EDT-provided software driver packages, see specifications for your EDT main board (PCI SS, PCI GS, or PCIe8 LX).
