Extron electronics SW HD 4K PLUS Series User Manual page 14

Input connectors — Connect HDMI video input sources to these female Type A HDMI
B
connectors.
NOTE: LockIt cable lacing brackets are provided with the SW HD 4K PLUS units.
These brackets secure the HDMI cables to the rear panel connectors and reduce
stress on the connectors, preventing signal loss due to loose cable connections
(see LockIt HDMI Cable Lacing Bracket Installation
information).
Output connector — Connect an HDMI display device to this female HDMI A
C
connector.
The EDID information is read from the connected output device via this connector and is
written to memory on each input whenever the output device is connected to this port
and powered on.
NOTE: The EDID information is also read and stored whenever power is recycled to
the connected output device or when the output device is replaced.
+V connector — The +V pin (SW2 and SW4) or the 3-pin connector (SW6 and SW8)
D
constantly outputs +5 VDC with 200 mA total (shared between pins). Use this pin when
power is needed for external Tally LEDs, such as Extron Show Me cables.
RS‑232 connector — Use this 3-pole, 3.5 mm captive screw connector for RS-232
E
communication with the switcher (including firmware updates).
To enable RS‑232 control, connect the Tx (transmit), Rx (receive) and G (ground) pins
to the serial port of your computer (see
LAN (Ethernet) connector — Use an RJ-45 cable to connect this jack to a LAN for
F
control of the switcher via Ethernet.
• Use a straight-through cable for connection to a switch, hub, or router.
• Use a crossover cable or a straight-through cable for connection directly to a PC.
Wire the connector as shown in the image below.

SW2 — The CONTACT/TALLY panel contains one 5-pole captive screw connector
•
with two pairs of pins labeled C (contact) and T (tally), and a +V pin that supplies
power to an optional indicator device.
SW4 — The CONTACT/TALLY panel contains one 5-pole connector with two pairs
of pins labeled C and T, and a +V pin that supplies power to an optional indicator
device. It also has a 4-pole captive screw connector with two more C-T pin pairs.
(Optional) Connect a push-button contact closure device to a C pin and to the G
(ground) pin of the 3-pole RS-232 connector (see figure 2,
page). Connect an indicator device, such as an LED, to tally output pin T of the
same pin pair, to identify the currently selected input when the front panel buttons
are not visible.
