Chapter 2

Overview and Operation

SCSI Decoder Command Set

This command set for the Vela CineCast Quad Pro decoder family performs per 
the SCSI-2 Standard. The Model 2000-0422 and Model 2000-0422-2 decoders 
use Firmware (microcode) Revision Q022. The Model 2000-0422-1 “Dash-1” 
version uses Firmware Revision F022. Any differences in the command set 
between the two firmware versions will be noted as appropriate. Contact Vela 
for the latest firmware revision and complete information on the command set, 
if needed. 

SCSI Command Sequence from Power-up, SCSI 
Reset, or Bus Device Reset

The CineCast Quad Pro decoder will report Check Condition to the first SCSI 
command (excluding 

INQUIRY

 and 

REQUEST

 

SENSE

). The host adapter (initiator), 

after seeing the check condition, should respond by performing a 

REQUEST

 

SENSE

.

Per SCSI recommendations, the initiator should renegotiate for synchronous data 
transfers and wide transfers. This is done to enable hot swap capability and proper 
negotiation for Sync and Wide data.
