(9434) Set Asynchronous Messages Enabled
Causes the module to send asynchronous messages to the host when they are ready.
By default this option is disabled on startup of the system. Once it is enabled, the temp record
is sent every 173 milliseconds until one of the following occurs:
• the temperature cycle becomes inactive
• a command is sent to disable the mode
• power is removed from the module
In asynchronous mode, the module might not respond immediately to messages from the
host. Avoid continuous polling of the module when asynchronous messages are enabled and
a temperature cycle is active.
