Precision Time Protocol (PTP) is a time protocol that can be used to synchronize com-
puters on an Ethernet network. SecureSync supports PTP Version1 and2, as specified in
the IEEE 1588-2002 and IEEE 1588-2008 standard, via two (2) Ethernet ports.
SecureSync can be configured as a PTP Master Clock or as a PTP Slave Clock.
Next to PTP specifications, this topic describes the PTP menu items and settings, and out-
lines how to set up SecureSync as a PTP Master or Slave.
