9.3.14 COMMANDS FOR PROHIBITION/PERMISSION OF DTV/HOMENET COMMUNICATION

7 Commands for prohibition/permission of DTV/HomeNet communication
Control device: DTV & HomeNet
Memory: ON/OFF of DTV communication prohibition mode
Applicable models: Only for models for North America
7 Functions
This is a command for forcibly prohibiting communication with DTV (for Elite series panels, communication using
HomeNet is included).
Normally, after the panel and the connected DTV are turned on, any operation is prohibited on the panel until startup of
the DTV is completed. However, on the production line, to avoid a drain on productivity, such waiting time must be
shortened. Thus, for the processes where the DTV is not necessary, such as panel adjustment, the existence of the DTV
can be ignored, to shorten waiting time.
7 Commands
S00
To exit DTV/HomeNet Communication
DTN
S01
To enter DTV/HomeNet Communication
