Set a New Password

Each Pro64 module can store a network password. However, the password

lock/unlock feature can only be used from the network Control Master.

Passwords can be changed only when the network is unlocked.

The password is a four‑digit number created using the numbered channel

activation buttons 1‑16 on the front panel. Passwords can include repeated

numbers (such as the default factory‑supplied password of 1‑1‑1‑1). When

creating a password, any string of numbers can be used, but note that only

the last four button presses are stored.

To set a new password, press

and then the

button. Key in a four‑digit button combination and then press

. The

channel buttons flash to indicate that the new password has been set.

Pressing the

button will exit the new password Function and leave

the original password intact.

Sample Alignment

All digital networks that allow daisy‑chained connectivity need to

compensate for sub‑millisecond latency build‑up between devices when

data is retransmitted. In the majority of cases, there is no audible effect (as

the individual delays are very small), but without compensation, these small

variations in latency can become an issue in certain applications as the

network grows in size.

On power up, each device in the network will calculate a sample alignment

value based on the current sample rate and will apply it as long as the

network is running. The next time the network sample rate is changed or

the system is power cycled, a new value will be calculated and locked in.

This sample alignment value will be referred to as the default value in the

text that follows. Using the default value will offer the simplest method of

operation.

However, to guarantee repeatable latency down to the microsecond, the

user has the option of measuring the sample alignment amount for a given

sample rate and then applying that calculated value every time the network

is powered up. This is referred to as a stored value in the text that follows. By

using these stored values, the Pro64’s unique software guarantees consistent

delays between each component of the network.

Sample Alignment Lock Status

The sample alignment query, Function 11, can be performed on the Control

Master or any remote unit in the network. The network can use the default

value (created at the time of power‑up) or a stored value.
