The MSI-P402 is a 32-bit quadrature decoder/counter card 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. Interrupts selection for IRQ3 thru IRQ9 are jumper selectable for managing counter roll-overs, if required. The unit is an 16-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.
