Preparing for Communications
• Write ID
(1) The CIDRW Controller is in IDLE. The host device requests the CIDRW Controller change its oper-
ational status to MAINTENANCE.
(2) The CIDRW Controller changes to MAINTENANCE and replies that it has changed state.
(3) The host device sends a Write ID Request message to the CIDRW Controller for Head 1. The
CIDRW Head 1 writes ID, and the CIDRW Controller returns the ID to the host devices.
• Write Data
The host device sends a Write Data Request message to the CIDRW Controller for Head 1 and Data-
Seg S02. The CIDRW Head 1 writes the data, and the CIDRW Controller returns the results to the host
device.
