Ch XX ISO: Each field will return a one (1) if the channel has a non-isolated
plug-on installed. A zero (0) indicates an isolating plug-on is installed.
Notes
A channel will not function without a plug-on module installed. A one (1)
indicates either a non-isolated plug-on is installed or that no plug-on module
is installed. DO NOT operate the module without a plug-on module
installed on every channel.
For 8-Channel configurations, the upper 8 bits (channels 09 through 16) are
set to 1’s (FF

).
