The MSI-P404 is a 32-bit quadrature decoder/counter card with index inputs designed for monitoring quadrature encoder inputs used in determining motor shaft positions and rotations in machine control and robotic applications. The card can be supplied with 2, 4, 6 or 8 channels. Each channel provides a 32-bit binary up/down counter with selectable 1X, 2X or 4X decoding and latched count outputs using Agilent HCTL-2032 decoders. For each input channel, connector J1 provides quadrature inputs with 10K pull-ups and surge suppressors for operation in harsh environments as well as +5V and ground for powering of user's encoders. Connector J2 provides index inputs with 10K pull-ups and surge suppressors. Each index channnel can be indivdually dissabled. Interrupt selection for IRQ3 thru IRQ9 are jumper selectable for managing counter roll-overs, if required. The unit is an 8-bit stackthrough PC/104 with I/O mapped 16-bit addressing for which the card base address is jumper selectable. A count reset to zero is provided for each individual channel. Operates from -40°C to +85°C.  Requires +5V only.
