Models: DKLA-22160, DKLA-23240 and DKLA-24320

IDE connector

Notes: Pin position 20 is left blank for secure connector insertion. Pin position A,B,C, and D are used for drive address setting.

Signal definition

The pin assignments of interface signals are listed as follows:

Notes:

1. "O" designates an output from the drive.
2. "I" designates an input to the drive.
3. "I/O" designates an input/output common.
4. "PWR" designates a power supply to the drive.
5. "(Resv)" designates reserved pins which must be left unconnected.
6. "*" these signal lines are redefined during the Ultra DMA protocol to provide special functions as detailed in the table below. These lines change from the conventional to special definitions at the moment the host decides to allow a DMA burst, if the Ultra DMA transfer mode was previously chosen via SetFeatures. The drive becomes aware of this change upon assertion of the -DMACK line. These lines revert back to their original definitions upon the deassertion of -DMACK at the termination of the DMA burst.
