Clock Master

One device in a Pro64 network will always be set as the network’s Clock

Master. In a network with only analog I/O modules, the module set as the

Control Master is set to be the Clock Master by default. The module set as the

Clock Master will have its Clock Master LED lit.

When digital I/O modules such as the 6416dio are used in a network,

incoming Word Clock or AES3 digital data streams (from channels 1/2 only)

can also be clock sources. It is only when a digital module is part of the

network that the Control Master and Clock Master functions can be assigned

to separate devices.

Changing the Network Clock Master

To set a 6416dio Digital I/O Module to be the network Clock Master when

another Pro64 module is the Control Master, press the Cl o C k Ma S t E r button

on the 6416dio. The Enter/Cancel LED and the Clock Master LED will blink;

confirmation is required. Press En t E r to set the 6416dio as the Clock Master

or press Ca n C E l to exit without making a clock change and return to the

previous setting.

Working With Multiple 6416dio Modules

When a Pro64 network contains multiple 6416dio Digital I/O Modules, any

of the 6416dio units can be made the network’s Clock Master while another

Pro64 module (analog or digital) functions as the Control Master. Once a

6416dio has been set to be Clock Master for the network, changing the

clock source to a different 6416dio is a two‑step process. In the first step, the

current Clock Master 6416dio needs to hand off the Clock Master duties to

the current Control Master module. Then a different 6416dio can take control

of the clock from the Control Master as in the example above.

To transition Clock Master from one 6416dio module to another in a network

where the Control Master and Clock Master are set to be different units:

On the Control Master, press its 1. Cl o C k Ma S t E r button.

The Enter/Cancel LED and the Clock Master LED will blink;

confirmation is required.

Press 2. En t E r to set the current Control Master device as the

Clock Master or press Ca n C E l to exit without making a clock

change and return to the previous setting.

Once the Clock Master function is being handled by the 3.

Control Master, press the Cl o C k Ma S t E r button on a differ‑

ent 6416dio. The Enter/Cancel LED and the Clock Master

LED will blink; confirmation is required.

Press 4. En t E r to set the new 6416dio device as the Clock

Master or press Ca n C E l to exit without making a clock

change and return to the previous setting.
