The Setup menu is used to configure the basic operational modes of the
XDS Encoder such as selecting which type of video is present, which data
channel will be shown on the decoder output, etc. A ")" symbol to the left
of the main level menu items allows them to be easily distinguished from
the front panel operating messages. The sub-menu choices are shown in
lower case to allow them to be easily distinguished from the main level
items. Items shown in bold are the factory default values.

effectively bypassing all processing circuitry. The relay can also
be forced into bypass from the Bypass Relay Enable parallel
port control pin. (See section 3.5.1)
Select Bypass=off to configure the encoder for normal
