2 Procedure
There are two possible configurations for a Chase Mode setup:
1. Master and Slave – One IMB is the master unit which feeds timecode to one slave unit and
the slave unit chases the master. This configuration allows for the synchronization of two IMBs
(Figure 1).

2. Chasing a Timecode Source – The IMB and ShowVault can chase timecode from any HD-
SDI source that has embedded LTC timecode. To use an embedded timecode source, the HD-
SDI signal must be duplicated with a Distribution Amplifier (DA). The IMB/ShowVault does not
support daisy chaining timecode signals. This configuration allows for more than two IMBs to
be synchronized (Figure 2).
