1. Introduction
PTP for the DXD-8: The DXD-8 Universal Clock is designed to be the central source of time in a modern A/V installation. As
a master clock generator it provides WC, AES and Video Sync. But with the addition of PTP, the DXD-8 truly becomes universal
by keeping traditional audio/video equipment and IP networks in perfect sync.
The DXD-8 has the capability of being a PTP Grandmaster or a PTP slave. As a PTP master, the DXD-8 can lock to external sync
sources such as WC, AES, Video Sync and 10 MHz, or to its internal crystal, while generating PTP sync. As a PTP slave, it can
lock to a Grandmaster while generating traditional sync signals (word clock, AES, video sync or 10MHz).

GPS and OCXO give the DXD line access to more stable time sources and gives the DXD's a higher priority to become PTP
Grandmaster. GPS also allows remote units to be in perfect sync.
2. Installation
2.1 DXD/PTP INSTALLATION (FIRMWARE) - DXD-8 ONLY
Before installing the DXD/PTP, be sure to update your DXD-8 with the latest firmware, available on the Brainstorm website.
When you purchased your DXD/PTP, you received a unique authorization key, a series of 4 numbers, separated by periods.
This key is only valid for the DXD-8 with the serial number used when you placed the order. Note that PTP is optional on the
DXD-8 only. A feature key is not required on the DXD-16.
Enter this key in Menu 9.5, FEATURE KEYS, under the main menu 9.0 UTILITY. After entering the authorization key, you will be
prompted to confirm your entry. A message will confirm that the feature key has been set.
This authorization procedure only needs to happen once, even with subsequent firmware updates.
2.2 DXD/GPS & DXD/OCXO INSTALLATION (HARDWARE)
For instructions on how to install the GPS receiver and the OCXO oscillator, see Appendix A & B. No authorization code is
required for either of these 2 options. New menus and displays will become available after hardware installation.
