Configuring the Adapter Chapter 3

Valid nodes must have 20-COMM-ER adapters connected to drives with
compatible Logic Command/Status words.

3.

Set Parameter 40 - [Peer A Input] to select the destination of the data that
is input to the drive as Peer A.

D

ata is used from the least significant word in the event of a mismatch in

Reference or Datalink sizes.

4.

If desired, set Parameter 41 - [Peer B Input] to select the destination of
the data to input to the device as Peer B.

5.

If the adapter receives a Logic Command, set the bits in Parameter 42 -
[Peer Cmd Mask]

that the device should use.

The bit definitions for the Logic Command word will depend on the
drive to which the adapter is connected. See

Appendix D

or the device

documentation.

If the adapter receives a Logic Command from both a master device and a
peer device, each command bit must have only one source. The source of
command bits set to ‘0’ will be the master device. The source of command
bits set to ‘1’ will be the peer device.
