Ciprico Rimfire 3880 Manuel D’Utilisation

There are two ways to issue a command to the RF3880 adapter. The simplest 
method involves the use of the Single Command structure. This 52-byte 
structure combines a Parameter Block and a Status Block into a single structure 
along with a field that specifies an interrupt level and ID. This Single Command 
structure is shown below. The important things to remember about the Single 
Command structure are:

•

It is designed to be used for initial set-up.

•

The first command you issue to the board after power-up or reset must 
use this structure.

The Single Command structure is illustrated for you below:

This section of the Single Command structure is where you build a Parameter 
Block containing information related to the command you wish to execute: 
Initiator Pass-through or Board-control. 

Most of the fields are command-specific; if there is data to transfer, for example, 
an address, address modifier and transfer count must be provided. For details 
about the parameter block fields necessary for a Initiator Pass-through 
command refer to Chapter 5, Initiator Pass-through Commands and a SCSI 
specification. For details about a Board-control command see Chapter 7, Board-
control Commands.

Reserved fields must be zeroed. If a non-zero value is permitted in a Reserved 
block, you may get an error.
