Electrical interface between the Micropolis 1370-Series drive and the host system is accomplished via connectors as shown in the figure below.
Signal Connector J1 is a 50-pin SCSI interface connector on the Device Electronics board. The signals on J1 include the 8-bit SCSI bus and various control and handshaking lines.
Multi-Function Connector J2 is used for device addressing and selecting other options. See 1370-Series Configuration Information
Power Connector J3 is a 4-pin connector used to supply +5V and +12V to the Motor Control board.
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.
