IMPORTANT
The XM-123 must be free of Poll connections when
configuring the Poll Output (Poll Response Assembly)
and Poll Size. Any attempt to download the parameters
while a master device has established the Poll connection
with the XM-123 will result in an error.
To close an existing Poll connection with an XM-440,
switch the XM-440 from Run mode to Program mode.
Refer to Changing Operation Modes on page 89.
To close an existing Poll connection with other master
devices, remove the module from the scan list or turn off
the master device.
