Modes
The term “mode” refers to the mechanism used in a request to specify the set of LRIS2Ks
that will answer the request.
Addressed mode
When the Address_flag is set to 1 (Addressed mode), the request contains the Unique ID
(UID) of the addressed LRIS2K.
Any LRIS2K that receives a request with the Address_flag set to 1 compares the received
Unique ID to its own. If it matches, then the LRIS2K executes the request (if possible) and
returns a request to the VCD as specified in the command description.
If the UID does not match, then it remains silent.
Non-addressed mode (general request)
When the Address_flag is cleared to 0 (Non-Addressed mode), the request does not contain
a Unique ID. Any LRIS2K receiving a request with the Address_flag cleared to 0 executes it
and returns a request to the VCD as specified in the command description.
Select mode
When the Select_flag is set to 1 (Select mode), the request does not contain an LRIS2K
Unique ID. The LRIS2K in the Selected state that receives a request with the Select_flag set
to 1 executes it and returns a request to the VCD as specified in the command description.
Only LRIS2Ks in the Selected state answer a request where the Select_flag set to 1.
The system design ensures in theory that only one LRIS2K can be in the Select state at a
time.
