Audio input port
(see
analog audio input into the switching transmitter via this stereo mini jack
connector.
NOTES:
•
The analog audio input on this connector is
in addition to the digital audio that may be
embedded in the HDMI inputs. See the figure
at right to identify the connector tip, ring, and
sleeve when you are making connections for the
switching transmitter from existing audio cables.
A mono audio connector consists of the tip and
sleeve. A stereo audio connector consists of the
tip, ring, and sleeve.
•
If you have removed the ground jumpers (see
page 32) because of ground potential differences, the DTP T USW 333 cannot
extend analog audio. The connected receiver outputs no analog audio.
•
The analog audio can be assigned to a specific input or set to be always
output (see
Assign analog audio

Over DTP RS-232 and IR port
modulated IR signal, or both into this 3.5 mm, 5-pole captive screw
connector for bidirectional RS-232 and IR communication (see
RS-232 connector wiring
F
DTP Output RJ-45 port
RJ-45 female connector on the switching transmitter. Plug the opposite end
of this cable into the DTP Input RJ-45 connector on a compatible receiver
(see
STP cable termination and recommendations
properly wire the RJ-45 connector and for detailed NOTES).
ATTENTION:
•
Do not connect this device to a telecommunications or computer data network.
•
Ne connectez pas ces appareils à des données informatiques ou à un réseau

Signal LED — Lights when the unit is outputting a TMDS clock signal on the DTP
output.
Link LED — Indicates a valid link is established between the units.
G
Remote Contact port
locally-contructed contact closure device into this 3.5 mm, 4-pole captive
screw port. Momentarily short the pin for the desired input (1, 2, or 3) to G to
select that input. To force an input to be always selected, leave the short in
place (see
Contact Closure Control
NOTES:
•
Contact closure control overrides front panel input selections.
•
For contact closure control, auto switch mode must be off (see
switch mode
