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 its
entirety before running or terminating the wires to ensure proper operation and to avoid damaging equipment.
OM3 Fiber SFP+ Guidelines
The EXF-300-H2 is designed to work with SFP+ OM3 MM ber cables providing a distance of 300m/984ft for all resolutions. This operation can be affected by
how the cables are terminated and routed within an installation. Care should be taken when terminating and routing based on the following guidelines.
• Fiber cable has a bend radius of 6.0cm/2.4in, when routing never exceed this radius as damage to the ber core can occur.
• Fiber core ends should be inspected for damage prior to terminating. Any scratches or blemishes can affect the performance of the connection.
• Never touch the end of the ber core with bare hands so that any oils or dirt can be transferred to the surface of the core.
• Refer to the guidelines and connection parameters from the ber cable manufacturer for more specic information regarding the cable being used.
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 and DP 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 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 CAB-IR-LINK product page for more information.
IR TX Port Pinout
Connection for IR TX (transmit) uses a 3.5mm (1/8in) mono plug.
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.
RS-232 Wiring
The EXF-300-H2 uses a 3-pin RS-232 with no hardware ow 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.
Pin 1 TX (Transmit) ---> To ---> RX (Receive)
Pin 2 RX (Receive) ---> To ---> TX (Transmit)
Pin 3 G (Ground) ---> To ---> G (Ground)
