Rear Panel Connectors

switch to positions 8 or 9 resets the video scaler and the audio de-

embedder.

• Option B (Rotary Switch): This opening features a 10-position

rotary switch that is reserved for future use and should be left at the

factory position of 1.

• Converted CVBS Out (from SDI, BNC-F): This female BNC

connector outputs CVBS (composite) video encoded from the

selected SDI input.

In the MDA model, HD-SDI signals are down-converted for proper

representation in composite video format. A switch is also installed

in the MDA model to allow selection of the video scaler for

communication through the RS-232 #2 connector.

This output functions regardless of other selection settings. This

feature enables encoding of the SDI signal to CVBS independent of

other monitoring functions (as long as a valid SDI signal is present

at the associated input).

• RS-232 #2 Select (Two-Position Select Switch on MDA model only):

This two-position slide switch is used to select the video scaler (up)

or the audio de-embedder (down) for communications through the

RS-232 #2 connector.

• RS-232 #2 (DB-9): In the SDA model, this DB-9 connector is used for

downloading programming, setup, and diagnostic information into

and out of the audio de-embedder. In the MDA model, it is used for

downloading programming, setup, and diagnostic information into

and out of the audio de-embedder or the video scaler. The MDA

model also features a two-position slide switch for selecting the

module that communicates through the connector.

• SDI In (1 & 2 on BNC): The

In 1 and In 2 BNC connectors accept

either stand SD-SDI (SDA model) or HD/SD-SDI (MDA model)

audio signals.

In the SDA model, only standard SD-SDI audio/video signals are

accepted at these two BNC input connectors.

In the MDA model, these two BNC connectors accept both high-

definition HD-SDI and standard SD-SDI audio/video signals (HD-

SDI signals are automatically down converted for monitoring).

Note:

You cannot input signals into both the balanced and

unbalanced connectors within the same AUX section.
