Model 5402
DANTE LEADER CLOCK WITH GNSS SYNCHRONIZATION
As such the unit is capable of acting as four independent
Leader clocks: PTPv1 for Dante primary, PTPv2 for Dante
primary, PTPv1 for Dante secondary, and PTPv2 for Dante
secondary. While the PTP processes are asymmetrical,
they do share the same internal timing reference. The
Model 5402 can also act as a PTPv1 and PTPv2 clock
follower but that would typically be utilized only for test
purposes. Standard and Redundant Dante (no AES67
support) uses PTPv1 and that is always enabled in the
Model 5402. AES67 utilizes PTPv2 clocking and if sup-
port for AES67 is desired within the Dante environment it
must be enabled using a configuration setting in the Dante
Controller application.
The Model 5402’s Main menu has four fields that display
the real-time sync status of the PTPv1 and PTPv2 functions
for the Dante primary and Dante secondary interfaces.
If the network configuration in Dante Controller for this
specific Model 5402 has been selected for Switched or
SMgmt the clocking status of the Dante primary
interface will be displayed. In this situation, the Dante
primary PTPv1 interface will show Leader, Follower, Link
Down, or Error (with the latter showing in red text). If AES67
support is enabled in Dante Controller then the same
choices will also be displayed in the primary PTPv2 field.
If AES67 support is not enabled then Disabled will show
in the primary PTPv2 field. Since Dante secondary is not
enabled then the secondary PTPv1 and secondary PTPv2
fields will show Disabled.
If the Model 5402’s network configuration has been se-
lected for Redundant or ReMgmt then both the
primary PTPv1 and secondary PTPv1 sync status fields
will display their respective sync status. They will show
the same choices as described above: Leader, Follower,
Link Down, or Error (with the latter showing in red text).
If AES67 support is enabled in Dante Controller then the
same choices will also be displayed in the primary PTPv2
and secondary PTPv2 fields. If AES67 support is not en-
abled then Disabled will show in both the primary PTPv2
and secondary PTPv2 fields.
Should Leader be displayed in a specific field it would indi-
cates that this specific Model 5402 is acting as the Leader
clock for the Dante network and clock function associated
with that field. If Follower is displayed this indicates that
this specific Model 5402 is obtaining its timing reference
from another Dante device on the network. This would be
the current display if this specific Model 5402 was serving
as a “hot” standby Dante Leader clock.
If Link Down is displayed this will indicate that a valid
Ethernet connection has not been made to the RJ45 jack
associated with that field’s Model 5402’s Ethernet interface.
A display of Error would indicate that this specific Model
5402 is having a permanent or temporary issue with its
internal circuitry. There may be occasions where Error
would display for a few seconds while Model 5402 circuitry
first becomes active.
