Clock Errors
If a clock error occurs, the Clock Master LED will blink indicating that an error
has occurred. Common causes for a clock error include:
Attempting to change the sample rate on an analog device •
other than the Clock Master in an all‑analog network
Attempting to change the clock source when the network
•
is password protected
Removing or changing external clock sources on a digital
•
I/O module
Incorrect configuration of an external clock source on a
•
digital I/O module
Network Sample Rate
When an analog device is the Control Master, the Control Master is
automatically designated as the Clock Master. It will remain the Clock Master
until a different analog module is made the Control Master or until a digital
module is added to the network and requests to be the Clock Master.
The Clock Master LED will light automatically on the Control Master when
that module is powered on. (Only a digital I/O module can be the source of
the network’s master clock without being the Control Master.)
The system’s internal master clock is derived from the sample rate currently
in use. The sample rate also affects the total number of available A‑Net Slots
available for use in the network.
The Sample Rate section of an I/O module’s front‑panel interface includes a
group of LED indicators for displaying the current network sample rate. One
LED will be lit at all times.
