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 any wires to ensure proper operation and to avoid damaging the equipment.
IMPORTANT! Wiring Guidelines
• The use of patch panels, wall plates, cable transmitters, 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 VGA, HDMI and USB 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.
• This product contains a USB-C connection that can be used as an audio/
video input. When using this connection verify that the USB-C cable used
supports audio/video functionality as not all USB-C cables support this
requirement.
Control Communication
RS-232 Wiring
The SW-740-TX uses a 4-pin RS-232 with no hardware flow control. Most
control systems and computers are DTE where pin 3 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.
