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 F

and then the C

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

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

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 firmware 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.
