Method 2

- Using the hard-wire connector JP3 on the drive carrier circuit board to allow

drive carrier interchangeability between Master/Slave configured receiving

frames

NOTE:

Cable wire not included.

For drive carrier interchangeability between Master/Slave configured receiving frames,it is

necessary to set the Master/Slave drive selection by both a hard-wire connection (cable wires

not included) between the drive and the drive carrier circuit board.

This method requires the fabrication of a cable wire (not provided). Refer to the following

sections to configure the drive carrier circuit board and jumper (JP4) located on the receiving

frame (both required for Method 2).

Configuring the Drive Carrier Circuit Board

The appropriate pins on the drive must be connected to JP3 on the carrier board. These

connections are required to set the Master/Slave configurations of the installed drive. Figure

5 illustrates the Drive Carrier Circuit Board.

When configuring the dual drives for interchangeable Master/Slave assignment, it is necessary

to emulate the Master and Slave drive jumpers and the specific drive's signal polarity definition

of Master and Slave.

= Pin 1

I/O Connector (J2)

The JP3 connector has 3 pins:

Pin 1

Not used.

Pin 2

Connects to the Slave/Slave Present signal of the drive. This signal indicates

whether a Slave D: drive is present or not.

Pin 3

Connects to the Master signal of the disk drive. This signal indicates that this

is the Master C: drive.
