Jumper settings

Note: Serial-ATA models do not have jumpers. Serial-ATA does not require you to set jumpers and operates without them.

Models: (Parallel only) HCS725050VLAT80, HCS725040VLAT80, HCS725032VLAT80, HCS725025VLAT80

Jumper locations

There are four jumper settings as shown in the following sections:
• 16 logical head default (normal use)
• 15 logical head default
• 32 GB clip
• Power up in standby
Within each of these four jumper settings the pin assignment selects Device 0, Device 1, Cable Selection, or Device 1 Slave Present as shown in the following figures.
The Device 0 setting automatically recognizes device 1 if it is present.

The Device 1 Slave Present setting is for a slave device that does not comply with the ATA specification.
Note: In conventional terminology "Device 0" designates a Master and "Device 1" designates a Slave.

Jumper settings

16 logical head default (normal use)

The figure below shows the jumper positions used to select Device 0, Device 1, Cable Selection, or Device 1 (Slave) Present.

Notes:

1. To enable the CSEL mode (Cable Selection mode) the jumper block must be installed at E-F. In the CSEL mode the drive address is determined by AT interface signal #28 CSEL as follows:
   • When CSEL is grounded or at a low level, the drive address is 0 (Device 0).
   • When CSEL is open or at a high level, the drive address is 1 (Device 1).
2. In CSEL mode, installing or removing the jumper blocks at A-B or C-D position does not affect any selection of Device or Cable Selection mode.
3. The shipping default position is the CABLE SEL position.

15 logical head default

The figure below shows the jumper positions used to select Device 0, Device 1, Cable Selection, or Device 1 (Slave) Present setting 15 logical heads instead of default 16 logical head models.

Notes:

1. To enable the CSEL mode (Cable Selection mode) the jumper block must be installed at E-F. In the CSEL mode the drive address is determined by AT interface signal #28 CSEL as follows:
   • When CSEL is grounded or at a low level, the drive address is 0 (Device 0).
   • When CSEL is open or at a high level, the drive address is 1 (Device 1).
2. In CSEL mode, installing or removing the jumper blocks at A-B or C-D position does not affect any selection of Device or Cable Selection mode.

Capacity clip to 2GB/32GB

The figure below shows the jumper positions used to select Device 0, Device 1, Cable Selection, or Device 1 (Slave) Present while setting the drive capacity down to 32 GB for the purpose of compatibility.

Note: The jumper setting acts as a 32GB clip which clips the LBA to 66055248. The CHS is unchanged from the factory default of 16383/16/63.

Power up in Standby

The figure below shows the jumper positions used to select Device 0, Device 1, Cable Selection, or Device 1 (Slave) Present to enable Power Up In Standby.

Notes:

1. These jumper settings are used for limiting power supply current when multiple drives are used.
2. Command to spin up is SET FEATURES (subcommand 07h). Refer to 12.28 Set Features.
3. To enable the CSEL mode (Cable Selection mode) the jumper block must be installed at E-F. In the CSEL
   mode the drive address is determined by AT interface signal #28 CSEL as follows:
   • When CSEL is grounded or at a low level, the drive address is 0 (Device 0).
   • When CSEL is open or at a high level, the drive address is 1 (Device 1).
