Modes

The term mode refers to the mechanism for specifying, in a Request, the set of LRI64

devices that shall answer to the Request.

13.1

Addressed mode

When the Address_flag is set to 1 (Addressed mode), the Request contains the Unique ID

(UID) of the addressed LRI64 device (such as an LRI64 device). Any LRI64 receiving a

Request in which the Address_flag is set to 1, compares the received Unique ID to its own

UID. If it matches, it execute the Request (if possible) and returns a Response to the VCD,

as specified by the command description. If it does not match, the LRI64 device remains

silent.

13.2

Non-addressed mode (General Request)

When the Address_flag is set to 0 (Non-addressed mode), the Request does not contain a

Unique ID field. Any LRI64 device receiving a Request in which the Address_flag is set to 0,

executes the Request and returns a Response to the VCD as specified by the command

description.
