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:
y
When CSEL is grounded or at a low level, the drive address is 0 (Device 0).
y
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 Device 0 position.
