To make these connections easier, the rear-panel connectors on the Brightness
Acceleration Engine and DHD Controllers are identified and color-coded as follows:
Digital Video Connection (G): Connect the HDMI 1 input on the Primary DHD Controller
to the Primary HDMI output on the Brightness Acceleration Engine. Similarly connect the
HDMI 1 input on the Secondary DHD Controller to the Secondary HDMI output on the
Brightness Acceleration Engine.
Analog (HD) Video Connection (A through E): Connect the HD 2 input on the Primary
DHD Controller to the Primary HD video output on the Brightness Acceleration Engine.
Similarly connect the HD 2 input on the Secondary DHD Controller to the Secondary HD
video output on the Brightness Acceleration Engine.
Analog (SD) Video Connection (F): Connect the Composite 1 input on the Primary
DHD Controller to the Primary Composite video output on the Brightness Acceleration
Engine. Similarly connect the Composite 1 input on the Secondary DHD Controller to the
Secondary Composite video output on the Brightness Acceleration Engine.
RS-232 Connection (H): Connect the RS-232 (To Accessory Box) connectors on the
Primary and Secondary DHD Controllers to each other, using the provided “null-modem”
(cross-over) cable.
