Introduction Use the HDMI 4x1 selection switcher to allow multiple HDMI source devices to be routed to a single, available HDMI input on a display. This can reduce the number of HDMI cables required to run to the display. The switch can be controlled using the front panel buttons, IR remote (included), or RS232 control. The switch is a high performance HDMI device supporting resolutions up to 1920 x 1200 at 60 Hz, and 1080p. It supports EDID and DDC, and is HDCP and HDTV compliant.

Operation of the remote controller Figure 2: Remote controller When select any one of the four input channels, press the corresponding key on the remote controller. Pressing and holding the key 1 for 3 seconds triggers the switcher to start or stop running in auto-switching or manual-switching mode. Interface connections Connection with the control system You can perform control functions via a control system (Clare Controls, Crestron, or other system.) using its RS232 communication port.
Connection with the computer To connect the switcher to a computer: 1. Use the DB9 cable (included) to connect the RS232 control port to a control system or computer. The adapter cable is pinned as follows: Pin 1: Connects to the 2 pin of the male 9-pin connector (Tx). Pin 2: Connects to the 5 pin of the male 9-pin connector (Gnd). Pin 3: Connects to the 3 pin of the male 9-pin connector (Rx). 2. Install the serial driver on the computer, if needed. 3.
System diagram Figure 3: System diagram HDMI Signal Auto-switching function The 4x1 HDMI selection switch comes with an auto-switching function. The switch continually checks for an input signal. Once detected, it automatically switches. Additionally, it can be controlled from the front panel, IR remote, or RS232 integration.
The auto-switching mode follows the principles listed below. General switching principle When there is no new source device connected to the input port, the 4x1 HDMI selection switcher detects the input ports one by one and from input 1 to input 4. Input 1 has the highest priority, and the input 4 has the lowest. This means that if input 1 is available, the 4x1 HDMI selection switcher will choose input 1. If not, it will choose the next input available for output.
Auto-switching mode and manual-switching mode can be set by pressing the input 1 button, or by entering an RS232 command. Auto-switching mode is the factory default. The operations are listed below. Button control Pressing INPUT 1 for three seconds toggles the switch between auto-switching mode and manual-switching mode. The Auto-SW LED designates which mode it is currently in. RS232 control Sending the RS232 command “602%” sets the switch to Manual mode and turns off the Auto-SW LED.
