LRIS2K states
An LRIS2K can be in one of 4 states:
●
●
●
●
Transitions between these states are specified in
and
Power-off state
The LRIS2K is in the Power-off state when it does not receive enough energy from the VCD.
Ready state
The LRIS2K is in the Ready state when it receives enough energy from the VCD. When in
the Ready state, the LRIS2K answers any request where the Select_flag is not set.
Quiet state
When in the Quiet state, the LRIS2K answers any request except for Inventory requests with
the Address_flag set.
Selected state
In the Selected state, the LRIS2K answers any request in all modes (see
Modes):
