Configuration Options

CABLE SELECT Option (JPl, position E)
The figure below shows the locations of the option jumpers and the connectors on the PCBA
(Device Electronics board).

SLAVE PRESENT Option (JPl, position C)

This option may be needed at system-level integration if the slave drive cannot be detected by the master drive; i.e., if the interface signals identifying the slave drive are not present

• A jumper installed at position C indicates that the slave drive is present.
  
• When the jumper is omitted at position C, the master drive detects the slave drive automatically by using signals DASP- and PDIACI-.
  

DRIVE IS MASTER Option (JP1, position D)

• A jumper installed at position D selects the drive as the master drive.
  
• The jumper omitted at position D selects the drive as the slave drive.
  
• When the jumper is omitted at position E, master/slave selection is accomplished via JP1, position D (DRIVE IS MASTER Option).

CABLE SELECT Options

• When a jumper is installed at position E, the signal level on Signal Connector pin 28 (refer to figure below) defines the drive as follows:
  
  A low (ground) at pin 28 sets the drive as a Master.
  A high (open) at pin 28 sets the drive as a Slave.
  

• When the jumper is omitted at position E, master/slave selection is accomplished via JP1, position D (DRIVE IS MASTER Option).

System Configuration

Most of today's computer systems determine the drive type (cylinders, heads, and sectors per track) automatically and configure themselves at start-up. You may, however, choose to configure your system manually. Manual configuration is a 3-step process:

1. Run the system Set-up program to enter the drive's specifications. Refer to your system manual for details.
2. Partition the drive using FDISK (a program on the DOS Program diskette). Refer to your DOS manual for details. Note that Micropolis drives are low-level formatted at the factory; no low-level formatting is required.
3. High-level format each drive partition using FORMAT (a command on the DOS Program diskette). Refer to your DOS manual for details.

The drive is ready for operation.

Dimensions and Mounting

Caution

The mounting screws must be selected so that they do not penetrate the bottom mounting holes by more than 0.20 inches or the side mounting holes by more than 0.156 inches. Screws that are too long may short to PCBA components.

The drive uses industry-standard mounting (see figure below) for 3.5-inch, 1-inch high, disk drives.

Recommended orientation is vertical on either side, or horizontal with the Device Electronics board down; other mounting orientations may be used.

No matter what mounting orientation is used, Micropolis specifies the maximum allowable
RDA casting temperature to be 600C (1400F).
