Jumper Configuration
(1) Device type
Master dedvice (device #0) or slave device (device #1) is selected.
(2) Cable Select(CSEL)
In Cable Select mode, the device can be configured either master device or slave device. For use of Cable Select function, Unique interface cable is needed.
Figure 5 and Figure 6 shows examples of cable selection using unique interface cables.
By connecting the CSEL of the master device to the CSEL Line (conductor) of the cable and connecting it to ground further, the CSEL is set to low level. The device is identified as a master device. At this time, the CSEL of the slave device does not have a conductor. Thus, since the slave device is not connected to the CSEL conductor, the CSEL is set to high level. The device is identified as a slave device.
