(1) SCSI cable
A terminating resistor is mounted on the drive when the drive is shipped. A
terminating resistor must be disconnected when the drive is not connected to an
end of the SCSI cable. Select a method of power supply to the terminating resistor
circuit according to the setting pins on the drive. See Section 4.2 for details.
(2) Power supply cable
The drive must be star-chain-connected to the DC power supply unit (one-to-one
connection) to reduce the influence of load variations.
3.4.3 External operator panel
Some set switch settings can be manipulated through the external operator panel
interface.
Figure 3.16 shows a recommended circuit for the external operator panel. Since
an external operator panel is not provided as an option, the user must design one
based on the system requirements and the recommended circuit.
