Wiring and Connections
WyreStorm recommends that all wiring for the installation is run and terminated prior to making connections to the switcher. Read through this section in it’s
entirety before running or terminating the wires to ensure proper operation and to avoid damaging equipment.
IMPORTANT! Wiring Guidelines
• The use of patch panels, wall plates, cable extenders, kinks in cables, and
electrical or environmental interference will have an adverse effect on
signal transmission which may limit performance. Steps should be taken
to minimize or remove these factors completely during installation for best
results.
• WyreStorm recommends using pre-terminated HDMI cables due to the
complexity of these connector types. Using pre-terminated cables will
ensure that these connections are accurate and will not interfere with the
performance of the product.
IR TX/RX Guidelines
• Using WyreStorm infrared emitters and receivers is the best way to ensure
that most IR coding formats are transmitted and received by the NetworkHD
system. Other 3rd party emitters and receivers can be used; however, these
devices must operate in the same manner as the WyreStorm devices.
• Due to differences in IR across 3rd party control systems their IR ports
should never be connected directly to a NetworkHD system as an
incompatibility may exist. WyreStorm offers a cable that compensates for
voltage differences as well adjusts for differences in the pins used within the
port. Refer to the
product page for more information.
IR TX Port Pinout
Connection for IR TX (transmit) uses a 3.5mm (1/8in) mono plug.
Tip:
Anode
Sleeve: Cathode (IR Signal)
IR RX Port Pinout
Connection for IR RX (receive) uses a 3.5mm (1/8in) stereo jack that outputs
+5V DC to power the included IR receiver.
Tip:
Ring:
IR Signal
+5V DC
Sleeve: Ground (GND)
RS-232 Wiring
The EX-35-H2-ARC uses a 3-pin RS-232 with no hardware flow control. Most
control systems and computers are DTE where pin 2 is RX, this can vary from
device to device. Refer to the documentation for the connected device for pin
functionally to ensure that the correct connections can be made.
3rd Party Device
Pin 1 TX (Transmit) ---> To ---> RX (Receive)
Pin 2 RX (Receive)
---> To ---> TX (Transmit)
Pin 3 G (Ground)
---> To ---> G (Ground)
WyreStorm Connector
Audio Return Input
This receiver contains a switch that determines where the Audio Return is
received to be sent back to the transmitter. Set this switch based on the
connections being used to send and receive audio.
Set the switch to
ARC
to receive audio from the
display via the HDMI connection.
Set the switch to
S/PDIF In
to receive audio from the
display via the S/PDI In connection.
