One-Step Master: The Sync packet is timestamped, then the
timestamp is inserted into the Sync packet in real-time, as it is trans-
mitted.
Two-Step Master: The Sync packet is timestamped, but the
timestamp value in the Sync packet is ignored. The actual T1 value is
transmitted in a "Follow-Up" packet after the Sync packet.
Note: PTP Masters must select one mode or the other to
operate in. The default mode is one-step.
Enable DHCP: This is a checkbox to enable or disable the delivery of IP
addresses from a DHCP Server. The default setting is enabled (the box is

but not available, the PTP Module will use this IP address. In the format
“#.#.#.#” with no leading zeroes or spaces, where each ‘#’ is a decimal
integer from the range [0,255].
Network Mask: When a DHCP server is not requested or is requested but
not available, the PTP Module will use this Network Mask. In the format
“#.#.#.#” with no leading zeroes or spaces, where each ‘#’ is a decimal
integer from the range [0,255].
Default Gateway: When a DHCP server is not requested or is requested but
not available, the PTP Module will use this Default Gateway. In the format
“#.#.#.#” with no leading zeroes or spaces, where each ‘#’ is a decimal
integer from the range [0,255].
