The three Drive Adress lines are decoded to select the correspondingly addressed drive. In multiple-drive systems, each drive must have its own unique address. Terminator Pack RN1 provides proper termination for the interface lines. When daisy-chaining the 1653 drives, the terminator is installed only in the last drive on the daisy chain. W1 Hard- or Soft-sectored mode ------------------------------- CLOSED The drive is configured to operate in the SOFT SECTOR mode. Address mark generation and detection are enabled, and the Sector/Address Mark Found interface signal is used to report address mark found. Sector size is selected by the host controller. OPEN The drive is configured to operate in the HARD SECTOR mode. The Sector/Address Mark Found signal is used to transmit sector pulses to the host controller.

Note that the factory default sector configuration is 36 sectors (W2 installed, W3 and W4 not installed). W5 Spindle Control Option -------------------------- CLOSED The drive must wait for a Start Spindle command to start the spindle motor. OPEN The drive automatically starts the spindle motor at power-on. (Factory default configuration) W12/W13 LED ------------ A jumper is installed at W12 or W13 to select the color of the LED. When a jumper is installed at W12, the red LED is selected. When a jumper is installed at W13 (the factory default configura- tion), the green LED is selected. W14 Frame Ground Option ------------------------ CLOSED Frame ground is connected to logic ground. x OPEN Frame ground is not connected to logic ground J12 RESERVED!
