Adding Pro64 Modules to a Network
When a new device is added to an existing Pro64 network, the new device
makes a request to the Control Master for inclusion in the network. During
this time, the new module’s blue A‑Net LED will flash. When the new module
has been enumerated by the Control Master, its blue A‑Net LED will then light
solidly to indicate that the Control Master has granted the module access to
the network. Adding a new module will interrupt network operation briefly.
Control Master and Clock Source
The Pro64 device designated as Control Master is also in control of the
network master clock. The front‑panel Clock Master LED lights to indicate
that a module is designated as the network’s master clock source. (The
6416dio Digital I/O Module is the only exception to this rule.)

The red Clock Master (CLK) LED lights when a Pro64 device is the Control
Master.
When an analog I/O module is the Control Master, no other analog module
can be used as a clock source in an all‑analog network. When a 6416Y2
console interface card is part of a Pro64 network, the 6416Y2 can be used
as a Clock Master for the network, but it must also be the network’s Control
Master to do so.
When using a 6416Y2 card as the Clock Master, the clock is derived from the
