Csel Setting - Fujitsu MHU2100AT - Mobile 100 GB Hard Drive Installation Manual

3.4.4 CSEL setting

Figure 3.14 shows the cable select (CSEL) setting.
Note:
The CSEL setting is not depended on setting between pins Band D.
Figure 3.15 and 3.16 show examples of cable selection using unique interface
cables.
By connecting the CSEL of the master drive to the CSEL Line (conducer) of the
cable and connecting it to ground further, the CSEL is set to low level. The drive
is identified as a master drive. At this time, the CSEL of the slave drive does not
have a conductor. Thus, since the slave drive is not connected to the CSEL
conductor, the CSEL is set to high level. The drive is identified as a slave drive.
