The HDMI Connector’s Sink Key Cache

If you need to persist the sink key cache on the HDMI UTPro matrix switching input connectors or clear persistence of 
the cache, follow the instructions provided.

Important: These commands apply to the routing state of the entire system. In addition, all HDMI matrix 
switching inputs in the system receive the request. These commands cannot be sent to specific inputs.

SEND_COMMANDs

The HDMI UTPro supports SEND_COMMANDs for saving and clearing the sink key cache on all of its HDMI matrix 
switching inputs.

To persist the Sink Key cache using SEND_COMMANDs:

Complete the procedure for initializing the system for InstaGate

®

 Technology (see page 67).

Enter SEND_COMMAND dvUTPro,"'INSTAGATEPERSIST'"

 

(persists the cache).

To clear persistence of sink key cache using SEND_COMMANDs:

Enter SEND_COMMAND dvUTPro,"'INSTAGATECLEAR'" (clears the cache and disconnects all currently 
routed signals).

Enter SEND_COMMAND dvUTPro,"'INSTAGATEPERSIST'" (persists the empty cache).

BCS Commands 

As a backup, the HDMI UTPro also supports BCS commands for saving and clearing the sink key cache on all of its 
HDMI matrix switching inputs. This procedure requires a terminal emulation program (e.g., TeraTerm, PuTTY, or 
HyperTerminal).

To persist the Sink Key cache using BCS commands:

Complete the procedure for initializing the system for InstaGate

®

 Technology (see page 67.)

Enter ~app! (persists the cache).
The HDMI UTPro will warm boot and display its boot screen.

To clear persistence of sink key cache using BCS:

Enter @et (clears the cache and disconnects all currently routed signals).
Note that the response to the @et command is @eV.

Enter ~app! (persists the empty cache).
