ELECTRICAL INTERFACE

1538 ELECTRICAL INTERFACE Electrical interface between the Micropolis 1538 drive drive and the host system is accomplished with five connectors: J1, J2, J3, J4, and J5.
Control Signal Connector J1 is a 34-pin board-edge connector. The signals on this connector control the drive and transfer drive status to the host controller. Data Transfer Connector J2 is a 20-pin board-edge connector. The signals on this connector contain read or write data. DC Power Connector J3 is a 4-pin connector used to supply +5V and +12V to the drive. Ground Connectors J4 and J5 are 3/16-inch spade lugs located on the HDA and frame, respectively, and are used for grounding purposes. System characteristics determine proper ground connection.
