Installation precautions
This product has special circuitry to protect it against moderate surges and static discharges.
However, to ensure reliable operation and long service life, it is important to take the
necessary precautions against any spikes, surges, lightening and static discharges.
Place the unit away from heat sources and allow adequate ventilation.
High quality High-Speed HDMI 2.0 cables (such as SY Stealth range) are highly recommended.
As much as possible cables should be routed away from any noisy sources and avoiding long
runs in close proximity to mains cables.

Controlling the SY-SMS44-18G
Seamless Matrix Switcher
When the SY-SMS44-18G is being used as a seamless matrix switcher, it can be controlled by any
one of the following three methods:
1. Front Panel
2. RS232 Control Software
3. LAN Control WebGUI
Front Panel Control
Each of the following operations is completed only when the ENTER key is pressed. If the ENTER
is not pressed or the CLEAR key is pressed, the switcher will return to the current settings.

2. The default audio routing follows with the video routing, but the user can select Audio
Manual routing mode by PC Tool or an RS232 command. Note that the front panel
does not switch audio when audio routing is in manual mode. This allows a user to
independently control the audio matrix switch from the PC Tool or using RS232
commands.
