Plattenparameter / Jumperbelegung ALPS DR311C Daisy-chain Single 2 Drive Master Slave C/D S S O ACT S Note 1 Note 1 DSP O S O HSP O O Note 2 Note 1) In a two drive system, it is possible to light LED with both drive's Status. In such case, the short pin "ACT" on the PCB of both drive should be shortet. Note 2) If this drive is connected to master drive that requires the slave present signal supplied from this drive via the interface signal LED CHAIN, then this drive's short pin HSP should be shorted. Drive Configuration The drive configuration (number of drive cylinders, heads and sectors) at power on can be selected by arranging the short pin DC. And number of heads and sectors can be set freely by "SET PARAMETERS" command (91H). So it is possible to emulate 512 bytes x 17 sectors per track system. The host must issue Set Parameters command after power and reset.
