22 Appendix B: Dual Projector Setup
This section describes the necessary steps to install and configure the two IMBs for a dual
projector setup. It also describes how to create a basic playlist.
In Dual IMB setup (using a single ShowVault and two IMBs for dual projector), the two IMBs are
not identical in terms of firmware and software configuration and in terms of serialization.
The primary IMB, a.k.a. the IMB SM (Security Manager) connected to the ShowVault via PCI-e,
is similar to a regular IMB in terms of serialization. It uses a specific firmware for Dual IMB setup
in the 32.xx version range. It can be updated back and forth, with regular IMB firmware used as
a regular IMB.
The secondary IMB, a.k.a IMB LD (Link Decryptor), which is not connected to the ShowVault via
PCI-e, has the same hardware as a regular IMB but is serialized differently in factory. This
different serialization is what allows it to behave as a secondary IMB, a Link Decryptor IMB. It
uses a specific firmware for Dual IMB setup in the 33.xx version range. It cannot be updated
back to regular IMB firmware and cannot be used as a regular/primary IMB.
In this section, the Primary IMB will be referred to as the SM (Security Manager), and the
secondary as the LD (Link Decryptor).
Note: Dolby 3D is not yet supported in Dual IMB setups.
