USER CONTROLS
The 2405EO is equipped with a 4 position DIP switch to allow the user to configure the module. The On
position is down, or closest to the printed circuit board. Table 5-1 gives an overview of the DIP switch
functions. Sections 5.1 and 5.2 give specific information about each of the DIP switch functions.

Table 5-1: DIP Switch Functions
The 2405OE will reclock SMPTE 259M (143 to 360 Mb/s),
SMPTE 344M (540 Mb/s) or DVB-ASI video signals.
The 2405OE will reclock SMPTE 310M (19.4 Mb/s) video signals.
Table 5-2: Reclock Mode Switch Setting
DESCRIPTION
Set both switches to the AUTO position to enable automatic switching
between the SDI 1 (optical) and SDI 2 (coaxial) inputs. The optical
input is selected as the default signal source. If the module loses lock
on the optical signal and a signal carrier is present on the coaxial input,
the module will automatically switch to the coaxial input.
Set switch 2 to the COAX position to select the SDI 2 (coaxial) input as
the only signal source.
Set switch 3 to the FIBER position to select the SDI 1 (optical) input as
the only signal source.
