Tip
Many PTP settings and detailed diagnostics on PTP can be monitored in the XCU menu: go
to the
Diagnostics > Media Network > PTP
menu to view them.
PTP setup
(this section is valid both in NativeIP and XCU mode)
• Status — shows PTP locking status. The following indications are possible:
• locked XCU is locked to the PTP grandmaster clock.
• Calibrating — a PTP Grandmaster is found and the camera system is calibrating to
the PTP Grandmaster;
• Listening — system is searching for a PTP Grandmaster on the IP Media Network;
• Disabled — PTP is switched off;
• Off — system is not connected to the IP Media Network.
• Profile — select the PTP protocol/domain used for locking to the PTP Grandmaster:
• SMPTE2059 — used for synchronization of broadcast media systems;
• AES67 — media profile of AES67;
• AES-SMPTE — combination of AES67 and SMPTE2059;
• User — User defined PTP settings. The parameters Domain Nr, Delay Req Interval
and Receipt Timeout must be set. For more information about these paramenters,
refer to the IEEE1588 PTP (Precision Time Protocol) specification.
Local reference
Camera
The locking source is connected directly to the camera’s Reference Input BNC connector
(see REF/AES connector , on page 138).
1 Select the reference signal. Go to the
Configuration > Reference
function and select
one of the following options:
• <SDI Input> camera locks to an SDI video signal applied to BNC-D. Note: this option
is not
• <PTP> the camera locks to a PTP signal on the IP Network (in NativeIP mode)
• <TriLvl> (= HD Tri-Level sync): the camera locks to the (expected) TriLvl input on the
REF/AES connector
• <Composite> (SD Black Burst): the camera locks to the (expected) Composite input
on the REF/AES connector
• <FreeRun> not locked (reference signals are ignored)
2 If you selected <SDI Input> or <PTP> as reference signal, the REF/AES BNC connector
can be programmed. Go to the
Configuration > Signals > BNC Ref/AES
function and
select one of the following options:
• <Ref In> Reference input
