SW2/4 HD 4K PLUS • Setup Guide (Continued)
3.
Connect HDMI input sources
to one or more of the SW HD 4K PLUS input connectors (see figures 1 and 2,
B
, on the previous page).
NOTE:
LockIt
®
cable lacing brackets, one for each HDMI input and output connector, are provided with the
SW HD 4K PLUS. These brackets can be used to secure the HDMI cables to the rear panel connectors
to reduce stress on the HDMI connectors and prevent signal loss due to loose cable connections. For
information on attaching the LockIt brackets, see the LockIt HDMI Lacing Bracket instructions in the
SW
HD 4K PLUS Series User Guide
card, available at
www.extron.com
.
4.
Connect an HDMI output device
to the output connector (
C
)
. By default, the EDID of this device is stored at
the HDMI output.
5.
Connect control devices.
Connect your computer
to one of the following SW HD 4K PLUS
communication ports to configure and control the
switcher via SIS commands:
•
RS-232 port
— Connect the unterminated
transmit, receive, and ground wires of the RS-232
cable to the provided 3-pole captive screw plug, as
shown in the illustration at right. Connect the plug
between the rear panel Remote shared connector
(
E
), and the serial port of your computer. Protocol
for the RS-232 port is 9600 baud, 8 data bits, 1
stop bit, no parity.
•
Config port
— Connect a USB mini-B cable between the front panel USB connector (see figures 4 and 5,
B
, on page 4) and a USB port on your computer for control via USB.
•
LAN port
— Use an RJ-45 cable to connect this jack (see figures 1 and 2,
F
) to a LAN for Ethernet control
of the switcher.
6.
(Optional) Connect contact closure and indicator devices
. The Contact/Tally section of the rear panel
contains one (SW2) or two (SW4) female captive screw connectors, each with two pairs of pins labeled
C
and
T
(see
1
in the illustration below right).
Each pin pair is labeled with the number of the HDMI input associated with it. Wire devices to these connectors
as follows:
a.
SW2 models
— Wire and connect the provided 5-pole plug to the 5-pole Contact/Tally captive screw
connector on the rear panel.
SW4 models
— Wire and connect the provided
5-pole
plug to the Contact In/Tally Out connector on the
left
(containing pin pairs 1 and 2), and wire and connect the provided
4-pole
plug to the connector on the
right
(pin pairs 3 and 4).
b.
Connect contact input and tally output devices to the pin pair for each input you are using, as follows:
•
To enable input switching via contact closure, connect a push-button
contact closure input device to pin
C
(
2
) and to the G (ground) pin
(
5
) of the 3-pole RS-232 connector.
•
To identify the currently selected input when the front panel buttons
are not visible, connect an indicator device, such as an LED, to tally
output pin
T
(
3
) of the same pin pair.
When the input you are using is selected, the corresponding tally out
pin shorts to ground, which activates the connected indicator.
c.
Insert the power wires for the contact indicator devices into the +V
connector (
4
).
d.
Press the button on the contact closure device to switch the connected input to the
output.
