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.
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.
