Installation and Operation
1. Connect HDMI sources to INPUT ports 1-4 using good quality HDMI cables.
2. Connect an HDMI display device to the HDMI OUT ports of the switcher.
3. Turn the power on using the included remote handset, ensuring LED power indicators are fully lit on the front of the switcher. If not, check to make sure the
HDMI cables are firmly connected.
4. To operate the switcher, press the SWITCH buttons on the front of the unit to scroll numerically through connected sources.
5. Alternatively, use the remote control handset to scroll forwards and backwards through the inputs or push buttons 1-4 corresponding to the connected
sources. Furthermore, a RS-232 connection from a control system can be used to control the device.

RS-232 Wiring
The EXP-MX-0402-H2 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.
Refer to
for details on setting RS-232 modes.

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.
